Objectives: Odontogenic sinusitis (ODS) is common but frequently overlooked condition that differs from rhinogenic sinusitis (CRS) and should be suspected in each case of unilateral sinusitis. Clinical symptoms such as foul smell, congestion, rhinorrhea, and unilateral maxillary sinus opacification with overt dental pathology on radiological scans are more suggestive of ODS than CRS, but the distinctive microbiological flora are another clinical factor in diagnosis. The aim of this study was to compare the microbiological load of ODS and CRS and their clinical presentation for better disease recognition and its predisposing factors. Methods: Adult patients scheduled for endoscopic sinus surgery were included in the study. Clinical data and radiological images were analyzed. The otolaryngologist assessed nasal endoscopy for mucopurulence or edema in middle meatus or sinuses, whereas dental specialist confirmed or ruled out the dental cause. Microbiological samples were collected after endoscopic maxillary antrostomy. After irrigation with 0,9% saline, the aspirated rinse was collected into sterile sets and sent for culturing. Results: The study group consisted of 84 patients, 55 with CRS and 29 with ODS. Streptococcus spp prevailed in the CRS group, whereas Staphylococcus spp prevailed in the ODS group. Statistically significant differences between the groups were found in type of discharge, degree of edema, and presence of polyps. However, no statistical correlations were noted for presence of bacteria in the culture and endoscopic or radiological findings. Conclusions: ODS and CRS share some common features: ODS more often presents with purulent discharge, localized maxillary involvement, and the presence of oral pathogens, and Staphylococcus spp in microbial profile.

Background and Clinical Significance: Acute pediatric rhinosinusitis is most commonly caused by Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. The involvement of Enterobacter species is rare and typically linked to chronic or nosocomial infections. Typical cases of acute rhinosinusitis in children present with abundant nasal discharge, headache, and fever and are generally managed with systemic antibiotics, nonsteroidal anti-inflammatory drugs (NSAIDs), mucolytics, and topical intranasal treatment. Atypical presentations prompt heightened clinical attention, and depending on the symptoms and patient status, surgical interventions might be considered. Case Presentation: We report the case of a previously healthy 5-year-old boy presenting with painful unilateral palpebral edema, minimal ipsilateral nasal discharge, and persistent headache despite standard rhinosinusitis therapy. Imaging tests revealed complete right maxillary sinus opacification. As the clinical response to ceftriaxone and dexamethasone was minimal, we opted for endoscopic sinus surgery. A nasal swab culture identified Enterobacter spp. in the nasal discharge. Conclusions: Unusual pathogens like Enterobacter spp. can cause acute sinusitis in children without prior risk factors. Early surgical intervention and culture-adjusted antimicrobial therapy remain critical for favorable outcomes. Full article

Background/Objectives: Oroantral fistulas (OF) are a challenging complication in oral and maxillofacial surgery, often requiring surgical intervention to restore sinus integrity. The Bichat’s buccal fat pad (BFP) has gained attention as a viable option for OF closure. This study aimed to evaluate the efficacy, safety, and clinical outcomes of BFP advancement for OF treatment. Methods: This prospective study included 20 patients diagnosed with OF. The surgical procedure involved isolation and advancement of the BFP to close the defect. Patients were followed up at 7 days, 45 days, and 6 months postoperatively, with clinical and radiographic assessments. The primary outcome was successful fistula closure at 6 months, while secondary outcomes included complication rates, sinus opacification on CT scans, pain levels, and quality of life improvements. Results: The overall success rate was 85.7%, with complete fistula closure achieved in 18 out of 21 cases (including one bilateral case). Minor complications occurred in 14.3% of cases. CT scans at 6 months showed complete resolution of sinus opacification in 81% of cases. Patients reported significant improvements in pain scores and quality of life. Conclusions: BFP advancement is an effective, safe, and minimally invasive technique for OF closure, offering high success rates and favorable clinical and radiographic outcomes. These findings support the use of BFP as a reliable option for managing OF in oral and maxillofacial surgery. Full article

Background and Objectives: Pulsed electromagnetic field (PEMF) therapy offers a promising approach to treating inflammatory diseases. Its notable anti-inflammatory and antimicrobial effects and enhancement of microcirculation in the nasal mucosa make it a valuable treatment option. Despite its potential, the use of PEMF for chronic rhinosinusitis (CRS) is still in its early stages, with limited exploration of its effectiveness. This study aimed to assess the impact of PEMF on alleviating symptoms such as fatigue, headaches, sinus opacifications, and ostiomeatal complex issues associated with CRS. Materials and Methods: Forty-seven patients of both genders with CRS, aged 19 to 40 years, were involved in this study. The participants were randomly assigned to either a magnetic or a control group. The magnetic group underwent a 10 min PEMF session with a 20-gauss magnetic field strength at 7 Hz thrice a week for a month. The control group received the same PEMF application as an inactive device. Before and after the intervention, researchers assessed fatigue levels with a visual analog fatigue scale (VAFS), headache intensity via a numerical pain-rating scale, and the status of sinus opacifications and ostiomeatal complex obstructions by computerized tomography (CT). Results: The study findings showed a significant reduction in fatigue and headache scores in the magnetic group compared to the control group (p < 0.05). Additionally, there was a notable improvement in sinus opacifications and ostiomeatal complex obstructions among participants who received PEMF therapy. Conclusions: PEMF therapy effectively reduces fatigue, headaches, and sinus opacifications in CRS patients, suggesting its potential for inclusion in CRS management guidelines to improve patient outcomes and quality of life. The results of this study indicate that PEMF represents a noninvasive and cost-effective approach for treating adults with mild-to-moderate CRS. Full article

Background/Objectives: Odontogenic sinusitis (ODS) is the most common cause of unilateral maxillary sinus opacification. Initial treatment consists of intranasal steroids and antimicrobial therapy. In case of persistence of the disease, endoscopic sinus surgery (ESS) is advised. It is still not clear what extension of ESS is required and whether frontal sinusotomy or ethmoidectomy is justified in ODS with frontal sinus involvement. Methods: Adult patients presented with uncomplicated recalcitrant bacterial ODS due to endodontic-related dental pathology were evaluated by an otolaryngologist and a dentist and scheduled for ESS. Sinus CT scan demonstrated opacification of maxillary sinus and partial or complete opacification of extramaxillary sinuses ipsilateral to the side of ODS. Patients were undergoing either maxillary antrostomy, antroethmoidectomy, or antroethmofrontostomy. Preoperative and postoperative evaluations were done with nasal endoscopy, dental examination, subjective and radiological symptoms. Results: The study group consisted of 30 patients. Statistically significant decreases in values after surgery were found for SNOT-22, OHIP-14, Lund–Mackay, Lund–Kennedy, and Zinreich scale. Tooth pain was present in 40% cases during the first visit and in 10% during the follow-up visit. Foul smell was initially reported by 73.3% and by one patient during follow-up visit (3.3%). Significantly longer total recovery time and more crusting was marked for antroethmofrontostomy when compared to maxillary antrostomy. Conclusions: ESS resolved ODS with ethmoid and frontal involvement in almost every case. Minimal surgery led to improved overall clinical success in the same way as antroethmofrontostomy without risking the frontal recess scarring and stenosis. Full article

Central compartment atopic disease (CCAD) is a distinct phenotype within chronic rhinosinusitis with nasal polyps (CRSwNP) with a pathophysiology that bridges the gap between allergy and CRSwNP, an association that was previously ambiguous. Understanding this endotype and its link to allergic disease is crucial for improved CCAD management. Using a systematic search and an independent dual-reviewer evaluation and data extraction process, this scoping review examines the clinical features, management options, and treatment outcomes of CCAD. Central compartment (CC) polypoid changes of the MT predominantly correlate with allergic rhinitis, increased septal inflammation, oblique MT orientation, and decreased nasal cavity opacification and Lund–Mackay scores compared to other CRSwNP subtypes. CCAD patients also exhibit higher rates of asthma, allergen sensitization, and hyposmia or anosmia. Surgical outcomes, including revision rate and SNOT-22 improvement, are favorable in CCAD as well. In conclusion, CCAD primarily affects atopic individuals and is managed using endoscopic sinus surgery combined with treating the underlying allergy. Continued research is needed to further refine understanding and develop optimal treatment strategies of this emerging CRS subtype. Full article

CBCT significantly impacts dental procedures and has brought significant reforms to our approach to diagnosis and treatment planning despite its limitations in differentiating soft tissues. It is an excellent imaging modality and quickly identifies sinus opacification and provides valuable insight into paranasal sinus pathologies, with considerably lower radiation exposure. The present study aimed to investigate the occurrence of maxillary sinus abnormalities in CBCT scans, identify the frequency, type, and location of these findings, and find the correlation between the distance of periapical lesions and radiographic changes in the maxillary sinus. Two examiners independently evaluated 117 patients to diagnose and classify the cases into different abnormality subtypes. The periapical lesions most closely related to the sinus were recorded. The diameters of the left and right maxillary sinus ostium and the distance of the ostium’s lower border to the sinus’s osseous floor were recorded. The findings were correlated with the age and gender of these patients. The present study reveals that sixty-one patients were diagnosed with mucosal thickening (52.1%). The sinus wall most affected by mucosal thickening was the maxillary sinus floor, followed by the medial and lateral walls. Of 19 patients with periapical lesions, 15 had maxillary sinus mucosal thickening, which is statistically significant (p = 0.004). The high occurrence of abnormalities in the maxillary sinus emphasizes the importance for the radiologist to comprehensively interpret the whole volume acquired in CBCT images, including the entire sinus. Incidental findings may be considered in the individual clinical context of signs and symptoms, reducing the risk of overestimating the real impact of radiographic findings. Full article

Introduction. The presence of bone septum in the maxillary sinus is one of the most common anatomical findings. So-called Underwood septa (US) are an atypical bone formation in the maxillary sinuses. Mostly they are quite easily found in CBCT studies and have major importance in sinus lift procedures in dental surgery. Furthermore, the shape, location, and size of the bony septa are important in each maxillary sinus surgery. Material and methods. A retrospective study of 120CBCT scans from the authors’ own database was conducted. Results. Approximately 37.5% of each CBCT was associated with the occurrence of US, while just 25% had a full septum, and a total of only 14 patients had a half septa. More females have US, while healthy pneumatized maxillary sinus is most commonly found (82.22%). There is no correlation between the occurrence of silent sinus syndrome (p = 0.174), mucosal thickening (p = 0.325), or retention cyst formation (p = 0.272). Most sinuses are without any opacification in CBCT evaluation (91.11%), while other syndromes are not statistically relevant. Conclusions. It seems that the occurrence of Underwood septa is not statistically related to any clinical, radiological, or pathological condition within the sinus (p > 0.05). Furthermore, a more full or partial appearance of US was found in female patients. Full article

This paper presents a literature review and a case of an 83-year-old otherwise healthy female patient with a history of recent syncope, a sudden-onset right-sided temporal headache, diplopia, and vision loss. An exam revealed right-sided upper eyelid ptosis, myosis, vision loss, ophthalmoplegia, and a positive relative afferent pupillary defect on the right eye. CT showed sphenoid sinus opacification, eroded lateral sinus wall, Vidian canal, disease extension to the posterior ethmoid air cells, orbital apex, medial orbital wall, and pterygopalatine fossa. An orbital apex syndrome (Jacod’s syndrome), Horner syndrome, and pterygopalatine fossa infection were diagnosed due to the acute invasive fungal sinusitis developed from a sphenoid sinus fungal ball. The patient was treated with antimicrobial therapy and transnasal endoscopic surgery twice to decompress the orbital apex, drain the abscess and obtain specimens for analysis. The right-sided ptosis, visual loss, ophthalmoplegia, and headache resolved entirely. No immune or comorbid diseases were identified, microbiological and histopathological analyses were negative, and MRI could not be performed on the presented patient. For that reason, the diagnostic procedure was non-standard. Nevertheless, the treatment outcome of this vision and life-threatening disease was satisfactory. Treating the fungal ball in an older or immunocompromised patient is essential to prevent invasive fungal rhinosinusitis and fatal complications. Full article

Introduction. Facial asymmetry might have many etiological factors. Most known and recognized factors are related to hemimandibular hyperplasia, elongation, condyle-related pathologies hemifacial microsomia, laterogenia, and others. In some cases, however, facial asymmetry has a different origin within the maxillary sinus (MS) bones. This rare entity as a silent sinus syndrome (SSS) causes secondary midfacial and maxillary asymmetry because of the retraction of the sinus walls. The authors present their own proposal for SSS/CMA (chronic maxillary atelectasia) classification and possible maxillary sinus disease alterations related to the scope of changes in the maxillary sinus walls, asymmetry, opacification, and related features. Material and Methods. The study consisted of 131 CBCT images which were evaluated. The authors focus on fourteen retrospective cone beam-computed tomography studies (CBCT) performed to establish and evaluate sources of facial asymmetry. Results. Neither presented maxillary and facial asymmetry cases correspond to the typical SSS/CMA findings. Asymptomatic maxillary sinusitis co-existing in maxillary asymmetry cases in patients suffering from skeletal malocclusion remains atypical for SSS pure and in-pure cases. The osteomeatal complex (OMC) patency is more common for pure forms. Conclusions. Computed tomography quite easily can identify the source of the problems in the maxillary sinus and identify SSS. Coexistent chronic rhinosinusitis might correspond with another MS pathology, CMA—chronic maxillary atelectasia. The scope and the degree of MS cause midfacial asymmetry; however, the scope of sinus opacification, osteomeatal complex drainage, and occurrence of other symptoms might be more or less present. The OMC patency is more common for pure forms. Full article

Little is known about alternative treatment options for rhinosinusitis (RS). We aimed to evaluate the efficacy of low-level laser therapy (LLLT) for RS in experimentally induced rabbit models of RS. A total of 18 rabbits were divided into four groups: a negative control group (n = 3), an RS group without treatment (n = 5, positive control group), an RS group with natural recovery (n = 5, natural recovery group), and an RS group with laser irradiation (n = 5, laser-treated group). Computed tomography and histopathological staining were performed for each group. mRNA and protein expression levels of local cytokines (IFN-γ, IL-17, and IL-5) were also measured. Tissue inflammation revealed a significant improvement in the laser-treated group compared with the RS and natural recovery groups (p < 0.01). In addition, sinus opacification in the CT scans and cytokine expression was reduced in the laser-treated group, though without statistical significance. LLLT could be an effective option for the management of RS concerning radiological, histological, and molecular parameters. Full article

Background: During oral rehabilitation, dental implants in the posterior maxilla can penetrate the maxillary sinus. The aim was to evaluate the presence of maxillary sinus abnormalities in patients with dental implants in the posterior maxillary region using cone-beam computed tomography (CBCT) images. Materials and Methods: This was a retrospective cross-sectional study, and CBCT scans of 199 patients (459 dental implants) were evaluated. Implants were assessed according to their relative location to the maxillary sinus floor (up to 2 mm from the maxillary sinus cortex, within 2 mm to intimate contact with the maxillary sinus cortex, apical third inside the maxillary sinus, two-thirds or more inside the maxillary sinus) and bone-fixation tissue (Alveolar ridge or Bone graft). Maxillary sinus abnormalities were classified. Kappa and Weighted Kappa and the Kruskal–Wallis test were applied. Results: A higher prevalence of mucosal thickening and non-specific opacification were observed in implants located within 2 mm to intimate contact with the cortex of the maxillary sinus floor. Of the 66 implants with apical thirds located inside the maxillary sinus, 31 (46.7%) were associated with sinus abnormalities and of all implants (n = 5) with two-thirds or more located inside the maxillary sinus, all of these were associated with sinus abnormalities. No association was observed in relation to implant bone-fixation tissue. Conclusions: This study found a significant association between dental implant placement near or within the sinus and sinus abnormalities, mainly mucosal thickening and non-specific opacification.

It is generally recommended that severe sinus membrane (SM) thickening should be treated prior to maxillary sinus augmentation (MSA), but during lateral MSA, inflammatory tissue/product may be removed by puncturing the SM. The present case report demonstrates surgical experience of lateral MSA with simultaneous inflammatory tissue/product removal for sinuses with severe opacification. In three patients requiring dental implant placement in the posterior maxilla, severe SM thickening was observed, but they were asymptomatic. The SM was gently elevated, followed by puncturing the SM, removing inflammatory tissue via the punctured site, draining, and thorough saline irrigation. Then, bone grafting and implant placement were performed with extra care not to spread bone substitute material into the punctured area. The postoperative pain following this procedure was more severe as compared to conventional MSA. Nasal bleeding was reported for 2–3 days. All implants were successfully integrated and demonstrated adequate function. Tissue samples retrieved during the surgery showed advanced inflammatory cell infiltration. The follow-up cone-beam computed tomographic scans revealed a significant reduction in SM thickening. In conclusion, inflammatory tissue/product removal by puncturing the SM can be applied during lateral MSA. However, more data should be needed due to the empirical nature of the present outcomes.

Purpose: To investigate the non-pathological opacification of the cavernous sinus (CS) on brain computed tomography angiography (CTA) and compare it with flow-related signal intensity (FRSI) on time-of-flight magnetic resonance angiography (TOF-MRA). Methods: Opacification of the CS was observed in 355 participants who underwent CTA and an additional 77 participants who underwent examination with three diagnostic modalities: CTA, TOF-MRA, and digital subtraction angiography (DSA). Opacification of the CS, superior petrosal sinus (SPS), inferior petrosal sinus (IPS), and pterygoid plexus (PP) were also analyzed using a five-point scale. The Wilcoxon test was used to determine the frequencies of the findings on each side. Additionally, the findings on CTA images were compared with those on TOF-MRA images in an additional 77 participants without dural arteriovenous fistula (DAVF) using weighted kappa (κ) statistics. Results: Neuroradiologists identified non-pathological opacification of the CS (n = 100, 28.2%) on brain CTA in 355 participants. Asymmetry of opacification in the CS was significantly correlated with the grade difference between the right and left CS, SPS, IPS, and PP (p < 0.0001 for CS, p < 0.0001 for SPS, p < 0.0001 for IPS, and p < 0.05 for PP). Asymmetry of the opacification and FRSI in the CS was observed in 77 participants (CTA: n = 21, 27.3%; TOF-MRA: n = 22, 28.6%). However, there was almost no agreement between CTA and TOF-MRA (κ = 0.10, 95% confidence interval: −0.12–0.32). Conclusion: Asymmetry of non-pathological opacification and FRSI in the CS may be seen to some extent on CTA and TOF-MRA due to anatomical variance. However, it shows minimal reliable association with the FRSI on TOF-MRA. Full article

Introduction: Bioabsorbable steroid-eluting implants are available as an adjunct for endoscopic sinus surgery (ESS) in the treatment of chronic rhinosinusitis (CRS). It is unclear which patients are most likely to benefit from this technology. We sought to determine if the severity of preoperative sinonasal inflammation influences the postoperative changes in patient-reported quality of life (QOL) and endoscopic appearance following ESS with implant placement; Methods: Consecutive adult patients undergoing ESS for CRS with ethmoidectomy and placement of a steroid-eluting implant over an 18-month period were prospectively included for study. Pre-operative sinus computed tomography (CT) opacification was evaluated using the Lund-Mackay score (LMS). Sinonasal Outcome Test (SNOT-22) scores and Lund-Kennedy endoscopic scores (LKES) for each patient were collected preoperatively and at three- and six-month intervals postoperatively. Serum eosinophilia (>6.0% on peripheral smear) and sinus tissue eosinophilia were recorded; Results: One hundred and thirty-six patients were included for analysis. Of these, 36.7% had polyposis, 15.4% had serum eosinophilia and 64.0% had tissue eosinophilia. The mean (standard deviation) SNOT-22 score was 45.5 (19.4) preoperatively, which improved postoperatively to 18.8 (14.1) at three months (p < 0.001) and 16.5 (14.0) at six months (p < 0.001). Similar results were found when stratified by the presence of polyposis, serum eosinophilia, tissue eosinophilia or high-grade CT findings (LMS > 6). Higher baseline LKES was observed for patients with eosinophilia or high-grade LMS, but these differences normalized at six months postoperatively; Conclusions: Patient-reported QOL and endoscopic appearance show improvement six months after placement of a steroid-eluting implant during ESS, irrespective of the presence of polyposis or eosinophilia.
