Background and Objectives: Patient-reported outcome measures (PROMs) are essential for evaluating outcomes in hand surgery, but the broad range of available instruments complicates selection and increases patient burden due to overlapping content. The Disabilities of the Arm, Shoulder and Hand (DASH), Michigan Hand Outcomes Questionnaire (MHQ), and Patient-Rated Wrist/Hand Evaluation (PRWHE) are the most frequently used PROMs. This study aimed to develop a merged instrument, the Comprehensive Hand Evaluation Form (CHEF), and to test whether CHEF-derived scores are equivalent to the original questionnaires. A secondary objective was to assess equivalence between pain ratings using an 11-item numeric rating scale (NRS) and a visual analogue scale (VAS). Materials and Methods: In this prospective study, adults with chronic atraumatic hand or wrist conditions completed the CHEF in the outpatient clinic and, three days later, the original DASH-G, MHQ-G, and PRWHE-G by mail. Equivalence was evaluated using two one-sided tests with margins set at half the minimal clinically important difference. Completion times were recorded. Results: Of the 100 patients, 57 could be included in the final analysis. Equivalence between CHEF-derived and original scores was demonstrated for PRWHE-G (mean difference −2.0; 90% CI −4.4 to 0.4 within ±7). Equivalence was not demonstrated for DASH-G (mean difference −3.5; 90% CI −5.7 to −1.3; margin ±5) or MHQ-G (mean difference 13.3; 90% CI 10.6 to 15.9; margin ±4.5). Thus, equivalence was achieved for one of three instruments. CHEF completion time was significantly shorter than the combined original questionnaires (median 10 vs. 15 min; p < 0.0001). For pain assessment, equivalence between the numeric rating scale and the visual analogue scale was observed at rest but not during activity. Conclusions: CHEF reduced completion time but achieved score equivalence only for PRWHE-G. These findings suggest that integrated PROM approaches may reduce burden, but do not consistently preserve equivalence across instruments. Full article

Background/Objectives: Chronic otitis media with effusion (OME) is the primary cause of conductive hearing loss in children. High recurrence rates following conventional surgery are often linked to incomplete nasopharyngeal clearance or persistent adenotonsillar biofilms. This study evaluates the long-term impact of endoscopic coblation adenotonsillotomy on middle ear clearance and disease recurrence compared to conventional curettage adenoidectomy. Methods: We conducted a prospective comparative study on 142 pediatric patients with persistent OME. Participants were allocated into Group A (Endoscopic Coblation Adenotonsillotomy, n = 72) and Group B (Conventional Curettage Adenoidectomy, n = 70). Groups were homogeneous regarding age, gender, and baseline audiological parameters (p > 0.05), all presenting with moderate conductive hearing loss and Type B/C tympanograms. Primary outcomes included tympanometric normalization (Type A conversion), auditory gain (Air–Bone Gap closure), and the rate of secondary ventilation tube (VT) insertion, monitored at 1, 3, 6, and 12 months. Results: At the 1-month follow-up, Group A showed a higher normalization rate than Group B (75.0% vs. 60.0%), though this was near the threshold of statistical significance (p = 0.058). However, at 3, 6, and 12 months, the coblation group demonstrated significantly higher recovery rates (p < 0.05). By 12 months, 94.4% of Group A maintained a Type A tympanogram compared to 78.5% in Group B. Group A achieved a significantly lower mean ABG at 12 months (8.2 ± 3.1 dB vs. 12.6 ± 5.4 dB, p < 0.001), reflecting a superior auditory gain (20.2 dB vs. 15.3 dB). Furthermore, the recurrence rate was significantly lower in Group A (4.1% vs. 15.7%, p = 0.021), resulting in a substantially lower requirement for secondary VT insertion compared to the conventional group (2.7% vs. 12.8%, p = 0.018). Conclusions: Endoscopic coblation adenotonsillotomy provides significant long-term clinical advantages over conventional curettage. By ensuring precise, atraumatic clearance of the Fossa of Rosenmüller and addressing the tonsillar biofilm reservoir, this technique achieves more stable middle ear aeration and superior auditory recovery, significantly reducing the necessity for secondary surgical interventions at one year.

Background/Objectives: Dental caries is one of the most prevalent chronic diseases in childhood, disproportionately affecting socially vulnerable populations. This scoping review aimed to analyze the clinical effects of selected minimally invasive materials and approaches, specifically mouthrinses, fluoride varnishes, silver diamine fluoride, and glass ionomer-based interventions, for the prevention and management of dental caries in pediatric patients, with emphasis on public health and community-based settings. Methods: This scoping review followed the Population, Concept, and Context (PCC) framework. Electronic searches were conducted up to 23 January 2026, using tailored strategies for mouthrinses, fluoride varnishes, silver diamine fluoride (SDF), and glass ionomer cements (GICs). Randomized clinical trials (RCTs) were included. Data extraction and qualitative synthesis focused on clinical outcomes and applicability in public health contexts. Results: Fifty-five RCTs were included. Fluoride- or chlorhexidine-based mouthrinses showed potential in controlling cariogenic biofilm, with evidence primarily based on microbiological outcomes. Fluoride varnishes were associated with enamel remineralization and control of early white spot lesions, particularly in supervised programs. SDF was reported to achieve high caries’ arrest rates in cavitated dentin lesions of primary teeth, while its preventive effect on sound surfaces appeared comparable to other fluoride-based interventions. GICs were associated with acceptable clinical performance as pit-and-fissure sealants and in atraumatic restorative treatment. Conclusions: Minimally invasive dentistry (MID) approaches show promise for the prevention and management of childhood dental caries in public health and community-based settings. However, these findings should be interpreted with caution due to the heterogeneity of interventions and outcome measures, the predominance of short-term and surrogate (microbiological) outcomes, and the absence of a formal risk-of-bias assessment. As a scoping review, the synthesis is narrative in nature, which limits the ability to draw definitive conclusions. Further studies with standardized clinical outcomes and longer follow-up are needed to strengthen the evidence. Full article

Minimally invasive parafascicular surgery (MIPS) represents a paradigm shift in the management of deep-seated brain tumors, enabling function-sparing resections previously limited to biopsy and/or medical therapy. Central to MIPS are structured frameworks guiding preoperative planning and intraoperative execution. The six-pillar concept—comprising imaging, navigation, atraumatic access, optics, resection, and postoperative care—provides a comprehensive approach to integrate advanced neuroimaging, tractography, tubular retractor systems, fluorescence-guided resection, and neuromonitoring to optimize functional outcomes. Five-point target-trajectory complex planning—craniotomy, outer radial corridor, inner radial corridor, target, and resection margins—translates preoperative imaging and functional mapping into a precise surgical trajectory, balancing maximal tumor resection with minimal disruption of eloquent brain structures. Preoperative assessment of tumor characteristics, vascular relationships, and cortical eloquence informs trajectory planning and intraoperative adjustments. A critical determinant of MIPS success is the intraoperative golden hour, referring to the high-risk period surrounding brain cannulation with a tubular retractor. Key principles include (1) precannulation system checks to ensure instrument readiness; (2) access injury prevention through optimized craniotomy sizing and sulcal preparation; (3) tubular-tumor targeting accuracy addressing brain and tubular translation, tumor displacement, and white-matter sleeves; and (4) intracranial pressure control strategies to minimize tissue strain and venous congestion. Overcoming this period enables a controlled resection phase guided by the above-mentioned surgical adjuncts. The six-pillar concept and five-point target-trajectory complex planning are the foundations of MIPS planning, whereas the intraoperative golden hour provides a roadmap for successful intraoperative delivery of the surgical plan.

Background: Arytenoid cartilage dislocation (ACD) is a rare but clinically significant complication of endotracheal intubation that may be misdiagnosed as transient vocal cord paralysis. The potential role of prolonged surgical positioning in ACD remains underrecognized. Methods: A 63-year-old male developed left posterior ACD following robot-assisted radical prostatectomy (RARP) performed in a steep Trendelenburg position for 3.5 h. Intubation was successfully achieved on the first attempt using a video laryngoscope with full glottic visualization and no apparent airway trauma. Postoperatively, the patient developed persistent dysphonia, dysphagia, aspiration, and tongue deviation. Initial flexible laryngoscopy suggested left vocal cord paralysis, whereas direct laryngoscopy on postoperative day 6 confirmed posterior arytenoid dislocation. Urgent closed reduction was performed, followed by structured voice therapy, which resulted in substantial functional recovery. Discussion: This case illustrates that ACD may occur despite technically optimal and atraumatic intubation and should be interpreted as reflecting a temporal association rather than a definitive causal relationship. Prolonged steep Trendelenburg positioning and extended operative duration may be considered potential contributing biomechanical factors, possibly mediated by venous congestion, mucosal edema, altered endotracheal tube dynamics, and cumulative shear stress on the cricoarytenoid joint. However, these mechanisms remain interpretive and hypothesis-generating. Conclusions: Prolonged steep Trendelenburg positioning and extended operative duration may represent possible contributing biomechanical factors in ACD, even in the setting of atraumatic intubation. Early laryngeal evaluation and timely reduction remain essential for optimal functional recovery. Full article

Background/Objectives: Atraumatic electrode array insertion should be targeted in cochlear implantation. Robotic insertion is used in many centers worldwide. Our objective was to evaluate manual electrode placement and robot-assisted placement using RobOtol^® on human temporal bones (TBs), in terms of endocochlear trauma and completion of insertion. Methods: Sixteen TBs originating from eight bodies were implanted with Medel-FLEX24 electrodes through the round window. The right TB was implanted manually, while the left TB of the same body was implanted using RobOtol^® for electrode insertion. Results were analyzed through micro-computed tomography imaging. No statistical analysis was used, given the small sample size; a descriptive interpretation of micro-CT scans was rather preferred. Results: In the “manual group”, there were two cases (25%) of insertion trauma: elevation of basilar membrane at basal turn (Eshraghi-stage-1). In the “robotic group”, there were two cases (25%) of insertion trauma: one case of elevation of basilar membrane at the middle turn (Eshraghi-stage-1) and one case of dislocation of all electrodes in scala vestibuli (Eshraghi-stage-3). There were six cases (75%) of incomplete insertion in the “manual group” and four cases (50%) of incomplete insertion in the “robotic group”. Conclusions: Both techniques of electrode placement yielded fairly similar results, in terms of endocochlear trauma and completion of insertion. New larger-scale cadaveric and clinical studies are needed to determine the possible benefit of robot-assisted electrode insertion in cochlear implantation. Full article

Cochlear implantation (CI) effectively restores hearing across the whole lifespan but may be followed by vestibular complaints, especially in adult recipients. The aim of this narrative review is to provide a comprehensive characterization of vestibular complaints after CI in adults, collecting clinical and instrumental data, as well as discussing the risk factors for their development. From data reported in the literature, we defined five recurring clinical presentations of postoperative vestibular disturbances (phenotypes): acute postoperative vestibular syndrome, benign paroxysmal positional vertigo (BPPV), delayed Ménière-like vertigo attributable to secondary endolymphatic hydrops, chronic postoperative disequilibrium, and stimulation-linked vertigo. According to the different pathogeneses underlying each presentation, the management of postoperative vestibular complaints should be phenotype-guided, including short-course vestibular suppressants and early mobilisation for acute presentations; canalith repositioning for BPPV; empiric therapy for hydropic-like episodes; and vestibular rehabilitation when imbalance is persistent, programming changes for stimulation-linked symptoms. Alongside this phenotype-driven approach, subjective symptoms are common across cohorts but are usually transient and persistent disability is uncommon. Furthermore, instrumental data across the studies indicate that objective abnormalities cluster in otolith and low-frequency canal measures: Cervical, ocular VEMP, and caloric responses are more often impaired than high-frequency canal function on vHIT, confirming histopathological studies showing preferential saccular involvement during the insertion of the electrode array. The risk of postoperative vestibular complaints not only appears to be modulated more by patient-related factors, especially pre-existing vestibular loss, but also by the aetiology of deafness, or age, rather than by device characteristics; atraumatic surgical approaches may further reduce this risk. This review emphasizes that future research on vestibular complaints after CI should adopt standardized phenotypes when evaluating symptoms, objective vestibular function, falls, and quality of life. Additionally, it should correlate these outcomes with hypothetical risk factors and detailed surgical reports. Full article

Background and Aim: The correct identification of patients presenting with chest pain and the stratification of their risk for major adverse cardiovascular events (MACE) is essential. The aim of this study was to evaluate subjects who came to the ED for chest pain through the chest pain score, the HEART score and the TIMI risk score in order to assess their validity and prognostic accuracy and to compare their performance. Methods: Patients included in the study met the following criteria: age ≥18 years, reported atraumatic chest pain, and consent to participate in the clinical study. Subsequently, the final scores were calculated based on the information collected and a follow-up was performed to assess the occurrence of adverse cardiovascular events (MACEs) at 30 days. The MACEs considered were a composite endpoint of STEMI or NSTEMI myocardial infarction, positive coronary angiography for critical lesions, percutaneous coronary angioplasty, coronary artery bypass grafting, and death. Results: A total of 102 patients were included in the study sample, divided into 76 patients who did not develop MACEs and 26 patients who experienced MACEs. The AUC values of the ROC curves of the chest pain score, HEART score and TIMI risk score were 0.8312, 0.9757 and 0.9378 respectively. Conclusions: All three scores examined were considered excellent tools to predict the onset of MACEs in patients with chest pain at different points of clinical management, although the HEART score outperformed both the chest pain score and the TIMI risk score in terms of prognostic accuracy.

Background: Intentional tooth replantation (ITR) is a promising treatment option for preserving teeth in cases where conventional endodontic therapy is challenging, or when previous endodontic treatment and apicoectomy have been unsuccessful. The procedure involves extracting the compromised tooth, preserving the alveolar socket and root surface, performing extraoral endodontic therapy, and replanting the tooth in the alveolar socket. Objective: An increase in evidence-based support for ITR has improved the viability of ITR as a treatment option for patients. This review aims to further establish and provide new areas of potential research for ITR with respect to root morphology, extraction, and surgical techniques, maintenance of the tooth socket, and methods for post-op stabilization. Materials and Methods: A literature review was performed across PubMed from 1 January 1980 to 1 July 2025, with a focus on oral surgery techniques, atraumatic extraction techniques, topographical discrepancies in root system anatomy, and ITR procedural outcomes. Conclusions: Although ITR is not a common procedure performed in contemporary clinical practice, gathering sufficient data on the variables influencing the procedure may help patient outcome and improve communication between the endodontist and oral surgeons.

Objectives: Post-extraction remodelling of hard and soft tissues results in volume reduction, leading to aesthetic challenges in planning prosthetic restorations, particularly in the anterior maxilla. This study assessed whether atraumatic vertical extraction, versus conventional extraction, could reduce postoperative volume loss and aesthetic compromises at the extraction site and adjacent teeth. Methods: Following randomized tooth extraction with unassisted healing in the test (Benex^® extraction, n = 10) and control group (conventional extraction, n = 10), postoperative scans were conducted at 30 days (t₁), 60 days (t₂), 90 days (t₃) and 12 months (t₄). Each scan was aligned with the baseline scan (t₀), and surface comparison was performed with five regions of interest (ROIs: central, mesial, distal, papilla mesial and papilla distal). Aesthetic parameters, including recession and Pink Esthetic Score (PES) of adjacent teeth, were clinically evaluated at each follow-up appointment. Statistical analysis used a mixed linear model accounting for confounding factors such as smoking, buccal bone integrity, gingival phenotype, and provisional use. Results: Both groups showed significant volume reduction from baseline to t₃ and t₄. The largest volume loss occurred in the central ROI in both test (t₄: −65.34 ± 36.89 mm³) and control group (t₄: −70.85 ± 30.96 mm³), with no significant difference between groups. A decline in PES and recession at the adjacent teeth was noted in both groups at 12 months. Conclusions: Both groups showed significant volume reduction with aesthetic impairment at the adjacent teeth’s soft tissue. Full article

Background/Objectives: Several imaging scores have been developed for subarachnoid hemorrhage (SAH), but their prognostic performance for long-term functional outcome and post-hospital complications remains insufficiently characterized. We evaluated whether five admission imaging scores (modified Fisher, Claassen, Hijdra, Graeb, IVH) independently predict 12-month functional outcome and major secondary endpoints. Methods: We performed a retrospective cohort study of 479 consecutive patients with atraumatic SAH recorded in a prospectively maintained institutional registry. Admission CT/MRI was scored by two board-certified neuroradiologists blinded to clinical outcomes. The primary endpoint was unfavorable functional outcome at 12 months (modified Rankin scale [mRS] 4–6). Secondary endpoints included 12-month mortality, delayed cerebral ischemia (DCI), post-hemorrhagic epilepsy, shunt-dependent hydrocephalus, return to work, and patient-reported health. Receiver operating characteristic (ROC) analyses and multivariable logistic regression adjusted for established predictors were conducted. Results: All imaging scores were significantly associated with the primary endpoint and demonstrated adequate discrimination (area under the curve [AUC] ~0.70–0.74), with the Graeb and IVH scores performing highest for long-term functional outcome, mortality, and shunt dependence. Associations with DCI and epilepsy were modest. In multivariable analyses, all imaging scores remained independently associated with mRS 4–6. Subgroup analyses showed stronger prognostic performance in good-grade SAH, aneurysmal SAH, and cases with concomitant intraventricular hemorrhage. Conclusions: Admission imaging burden independently predicts 12-month functional outcome, mortality, and shunt dependence after SAH. Incorporating IVH-oriented measures alongside established clinical grading may improve individualized risk stratification, particularly in good-grade and aneurysmal SAH. Full article

Cardiovascular clamping procedures can cause tissue traumatization, leading to serious adverse events interrupting blood flow and causing life-threatening hemorrhage. The aim of the study is to evaluate the properties of 3D-printed, high-elasticity elastomeric materials—BioMed Flex 50A and 80A (Formlabs Inc., Sommerville, MA, USA)—in terms of their suitability for the fabrication of atraumatic inserts used for surgical clamping instruments. To show the importance of the elaboration of the new atraumatic materials, finite element simulations of blood vessel compression by a surgical tool were validated experimentally with porcine vessels, and histopathology assessed the tissue response. These results confirm that excessive clamping forces can cause vessel wall stratification and rupture. Specimens BioMed Flex 50A and 80A underwent surface, mechanical, and biological testing, including topography, wettability, acoustic microscopy for structural voids, cytotoxicity with human dermal fibroblasts, pro-inflammatory marker analysis, and bacterial biofilm assessment. The results of the testing of the 3D-printed BioMed Flex 50A and 80A materials show good potential for applications in safe atraumatic surgical instruments. Further research may include the possibilities to develop 3D-printed metamaterials with pressure adapting properties. Full article

Background/Objectives: Scaling is central to non-surgical periodontal therapy; however, it is often perceived as uncomfortable, particularly in periodontitis. Psychological distress may amplify pain and reduce adherence. This comparative pilot study assessed whether ultrasonic technology influences patient-reported pain and psychoemotional status while quantifying the contribution of the periodontal condition and baseline psychological factors. Methods: A monocentric split-mouth design enrolled 42 adults (21 with stage I–III, grade B periodontitis; 21 periodontally healthy). Maxillary scaling was performed with Device nr.1 and mandibular scaling was performed with Device nr.2, and no anesthesia was used. Pain was measured immediately post-procedure using the Short-Form McGill Pain Questionnaire (SF-MPQ; sensory and affective subscales). Psychological status was assessed pre- and post-session with the Kessler Psychological Distress Scale (K10) and the Rosenberg Self-Esteem Scale (RSES). Construct validity was examined via exploratory factor analysis. The Mann–Whitney U, Wilcoxon signed-rank, Spearman’s ρ, and Cliff’s δ were applied (α = 0.05). Results: The overall pain was low. Between devices, sensory pain did not differ, whereas affective pain was modestly lower with the “No Pain” device (p = 0.017). Periodontitis was the dominant determinant of pain: higher sensory (U = 509.00, p = 0.0004; δ = 0.42) and affective scores (U = 290.00, p < 0.0001; δ = 0.67) occurred irrespective of device, while device-related effects were negligible (sensory δ = −0.03) to small (affective δ = 0.27). Somatic distress correlated with affective pain (ρ = 0.25, p = 0.023) and was borderline for sensory pain (ρ = 0.21, p = 0.060); emotional distress showed no significant associations. During the session, K10 scores decreased and RSES values increased, indicating immediate psychoemotional benefits. Conclusions: Pain perception during scaling is shaped primarily by periodontal status and psychological distress rather than by ultrasonic technology per se. Although the electronic module to dynamically adjust the power of the instrument technology may attenuate the affective component, standardized atraumatic techniques and routine psychosocial screening are likely to yield greater gains. The observed short-term improvements in distress and self-esteem support integrating patient-reported outcomes into individualized, patient-centered periodontal care. Full article

Background and Clinical Significance: Advanced periodontitis with severe vertical bone loss and grade III mobility is usually managed by extraction and implant placement. Digital workflows and modern regenerative techniques have opened the possibility of preserving teeth that would traditionally be considered for extraction. This report describes a digitally guided modified intentional replantation (MIR) protocol applied to a maxillary tooth with severe periodontal involvement and unfavourable prognosis. Case Presentation: A 68-year-old male, non-smoker, with a history of heart transplantation under stable medical control, presented with generalized Stage IV, Grade C periodontitis. Tooth 21 showed >75% vertical bone loss, probing depths ≥ 9 mm, bleeding on probing, and grade III mobility. After non-surgical therapy and periodontal stabilization, a CAD/CAM-assisted MIR procedure was planned. Cone-beam computed tomography (CBCT) and a 3D-printed tooth replica were used to design a surgical guide for a new recipient socket. The tooth was atraumatically extracted, stored in chilled sterile saline, and managed extraorally for approximately 10 min. Apicoectomy and retrograde sealing with Biodentine^® were performed, followed by immediate replantation into the digitally prepared socket, semi-rigid splinting, and guided tissue regeneration using autologous bone chips, xenograft (Bio-Oss^®), enamel matrix derivative (Emdogain^®), and a collagen membrane (Bio-Gide^®). A conventional orthograde root canal treatment was completed within the first month. At 12 months, tooth 21 exhibited grade 0 mobility, probing depths of 3–4 mm without bleeding on probing, and stable soft tissues. Standardized periapical radiographs and CBCT showed radiographic bone fill within the previous defect and a continuous periodontal ligament-like space, with no signs of ankylosis or root resorption. The tooth was fully functional and asymptomatic. Conclusions: In this medically complex patient, digitally guided MIR allowed preservation of a tooth with severe periodontal involvement and poor prognosis, achieving favourable short-term clinical and radiographic outcomes. While long-term data and larger series are needed, MIR may be considered a tooth-preserving option in carefully selected cases as an alternative to immediate extraction and implant placement.

Background/Objectives: Tooth extraction is known to cause both bone loss and soft tissue collapse, changes that can complicate implant placement. While alveolar ridge preservation techniques have been proposed to limit these alterations, they often fail to maintain both hard and soft tissue dimensions at the same time. Placental-derived extracellular matrices offer a biologically active adjuvant, providing structural proteins that may support healing. The purpose of this study was to assess whether a flowable decellularized Human Placental Connective Tissue Matrix (HPCTM), combined with an allogeneic bone substitute, could improve ridge preservation by addressing changes in soft tissue as the primary outcome and underlying bone volume as the secondary outcome. Methods: In a split-mouth, randomized pilot trial, hopeless teeth in opposite quadrants were atraumatically extracted. Test sockets were grafted with allograft mixed with HPCTM, while control sockets received allograft alone. Healing was followed clinically and digitally using intra-oral scans; standardized photographs at 10, 21, and 30 days post-operatively; and cone-beam computed tomography at 4 months post-operatively. Results: Ten patients completed the study (10 test sites and 10 control sites). Sites treated with HPCTM showed faster and more stable healing. Gingival shrinkage was consistently reduced at test sites, with Hodges–Lehmann median differences of 0.50 mm at Day 10 (95% CI: 0.29–0.62; p = 0.0039), 0.54 mm at Day 21 (95% CI: 0.42–0.65; p = 0.002), and 0.54 mm at Day 30 (95% CI: 0.39–0.68; p = 0.002). Radiographically, test sites lost significantly less bone volume (28.24 ± 2.43%) compared with controls (38.85 ± 1.29%; p = 0.019). Conclusions: Within the limits of this study, HPCTM appears to support better preservation of both gingival architecture and alveolar bone after extraction. Full article
