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: Chronic rhinosinusitis with or without nasal polyps (CRSwNPs/CRSsNPs) is an inflammatory disease that is becoming increasingly associated with laryngopharyngeal reflux disease (LPRD). Although symptom-based questionnaires, such as the Reflux Symptom Index (RSI) and Reflux Symptom Score (RSS), are widely used, there is a lack of objective endoscopic tools for assessing the nasopharyngeal and nasal manifestations of reflux. The Nasopharyngeal Reflux Endoscopic Score (NRES) is a novel endoscopic scoring system that was developed to address this issue. Objective: The objective of this study was to evaluate the diagnostic accuracy of the NRES in identifying LPRD in patients with CRS, compared with a clinical reference standard. Methods: A prospective diagnostic accuracy cohort study was conducted at two tertiary care centers in Astana, Kazakhstan, from September 2023 to February 2025. A total of 216 adults were enrolled and divided into three groups: CRS with suspected LPRD (n = 116), CRS without LPRD (n = 69), and healthy controls (n = 31). CRS was diagnosed according to the EPOS 2020 criteria. LPRD was defined using a composite reference standard comprising clinical assessment, RSS > 13, RSI, and selective 24 h pH monitoring and gastrointestinal endoscopy. All participants underwent nasopharyngeal and laryngeal endoscopy, with NRES, L-K, RFS, RSI, and RSS assessments at baseline and at 6 and 12 months. Receiver operating characteristic (ROC) analysis was used to evaluate the diagnostic performance, and Wilcoxon tests were used to analyze the changes in scores. Correlation and regression analyses were used to explore associations between scales and predictive factors. Results: At baseline, NRES scores were significantly higher in the CRS with LPRD group (mean: 11.59) than in the CRS without LPRD group (mean: 3.10) and the healthy control group (mean: 2.16) (p < 0.001). ROC analysis demonstrated excellent diagnostic accuracy, with an area under the curve (AUC) of 0.998 (95% confidence interval (CI): 0.994–1.000), a sensitivity of 98% (95% CI: 94–100%) and a specificity of 96% (95% CI: 91–99%) at an optimal cut-off point of 8.5. NRES scores showed strong correlations with RSI, RSS, and RFS scores (r > 0.76, p < 0.001). A longitudinal assessment revealed significant reductions in all scores after treatment with proton pump inhibitors and lifestyle modifications, with sustained improvement at 12 months. Regression analysis found no significant effect of age, gender, or GERD severity (LA classification) on NRES scores. Conclusions: The NRES is a highly sensitive and specific endoscopic tool for identifying nasopharyngeal changes associated with LPRD in CRS patients. It demonstrates strong correlations with established symptom-based and laryngoscopic reflux assessments and responds to anti-reflux therapy over time. The NRES may, therefore, be a valuable objective adjunct in the comprehensive evaluation and longitudinal monitoring of LPRD-associated CRS. Full article

Background: When considering the effects of dupilumab on severe chronic rhinosinusitis with nasal polyps (CRSwNPs), dupilumab is expected to achieve CRSwNPs remission. The aim of this study was to assess the rate of remission of CRSwNPs with comorbid asthma and its predictors on a 24-month course of dupilumab. Methods: Adult patients with severe CRSwNPs and comorbid asthma who had completed a 24-month course of dupilumab were included in this post hoc analysis. The primary outcome was the rate of CRSwNPs remission at 12 and 24 months of dupilumab. The secondary outcome was to identify factors associated with CRSwNPs remission at 12 and 24 months. Based on the European criteria and a previous definition, remission was defined as the absence of symptoms, improved quality of life, no need for surgery, no exacerbations, recovery of olfactory function, and inactive disease by nasal endoscopy for ≥12 months. A rigorous six-component remission, including olfactory testing, was initially used. Results: Of 16 patients, 4 (25%) and 5 (31%) achieved six-component remission of CRSwNPs at 12 and 24 months, respectively. Patients with shorter disease duration and better olfactory function at baseline achieved six-component remission of CRSwNPs more frequently than those without at 24 months (both p < 0.05). Conclusions: Remission of severe CRSwNPs with comorbid asthma is attainable with a 24-month course of dupilumab. Full article

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a persistent inflammatory disorder of the upper airways, severely impacting quality of life. Dupilumab, targeting type 2 inflammatory pathways, is effective in managing severe, uncontrolled CRSwNP. However, the comparative accuracy of endoscopic scoring systems in monitoring therapeutic response to dupilumab remains unclear. This study compared the accuracy of the nasal polyp score (NPS) and the modified Lund–Kennedy endoscopic score (M-LKS) in assessing dupilumab response. Methods: A retrospective cohort analysis included 66 severe CRSwNP patients treated with dupilumab at Padua University. Endoscopic scores (NPS and M-LKS), patient-reported outcome mesures (PROMs), and clinician-reported outcome measures (CROMs), including peak nasal inspiratory flow (PNIF) and the Sniffin’ Sticks test, were evaluated at baseline and over 24 months. Results: Both NPS and M-LKS showed significant reductions over time (p < 0.001), significantly correlating with PNIF (p < 0.001). Given time and patient, PNIF emerged to be the only covariate related to endoscopic scores. No significant differences were observed between NPS and M-LKS regarding clinical outcome associations, suggesting equivalent accuracy. PNIF was identified as a critical predictor of endoscopic improvement, highlighting its clinical utility. These findings reinforce the role of standardized endoscopic metrics in assessing the efficacy of biologic therapies for CRSwNP. Full article

Acute invasive fungal rhinosinusitis (AIFR) is a rare, severe, and life-threatening opportunistic infection associated with high mortality and morbidity. Rapid and accurate diagnosis and treatment are crucial for survival and effective disease management. Diagnosing AIFR is challenging because no single pathognomonic feature exists other than surgical biopsy showing fungal angioinvasion and necrosis. This narrative review focuses on the diagnostic challenges and pitfalls, emphasizing the critical clinical value of magnetic resonance imaging (MRI) for early diagnosis of AIFR. It includes selected cases that illustrate the significance of MRI. When AIFR is suspected, clinical symptoms, nasal endoscopy, blood samples, and facial computed tomography all provide non-specific information. In contrast, MRI can identify signs of devitalized sinonasal mucosa consistent with AIFR. The absence of mucosal enhancement on T1-weighted images, combined with restricted diffusivity, are characteristic MRI features of AIFR. The cases presented underscore the usefulness of MRI in supporting clinical suspicion of AIFR and accurately determining its topography, thereby guiding early surgical biopsies and debridement. In suspected cases of AIFR, MRI serves as a valuable supplementary, non-invasive tool to help determine whether prompt surgical biopsy or debridement is necessary, thereby enhancing early diagnosis and improving survival rates. Therefore, the threshold for conducting an MRI in these cases should be low. Full article

Fungal rhinosinusitis (FRS) can be classified into invasive and non-invasive forms, with the fungal ball (FB) representing a common non-invasive type with generally favorable outcomes post-operatively. The clinical presentation of FB can vary and be non-specific, and it is important to consider a wide differential diagnosis for sinonasal masses, including malignancy. We present the case of a 74-year-old female presenting with a two-year history of nasal obstruction and drainage. She has a history of breast cancer and prior maxillomandibular surgery, and imaging showed a poorly defined mass in the right maxillary sinus with possible hemorrhagic and/or proteinaceous content. Rigid nasal endoscopy revealed a friable mass, and endoscopic sinus surgery findings were consistent with FB. This case exemplifies the need to consider a broad set of differential diagnoses when evaluating sinonasal masses, especially if the patient has a prior malignancy or maxillomandibular surgical history, including FB and metastases to the paranasal sinuses. Given the presence of non-specific symptoms, it is important to consider early imaging for patients with distorted anatomy and a history of malignancy. Endoscopic sinus surgery, with high success rates, is the gold-standard treatment for FB. Full article

Background/Objectives: Rhinogenic contact point headache (RCPH) is a controversial secondary headache disorder involving mucosal contact points in the nasal sinuses. The efficacy of surgical versus medical management has been debated, with some studies showing excellent long-term outcomes but others citing placebo effects. This study aimed to clarify the correlation with nasal anatomical variation detected by CT and RCPH treatment outcomes. Methods: A prospective cohort study was conducted on 90 RCPH patients undergoing surgery or medical therapy. Patients were diagnosed using CT scans, endoscopy, and lidocaine testing. The surgery group had endoscopic procedures to remove contact points. The medical group received intranasal steroids. Outcomes were measured by visual analog scale (VAS) for pain and headache frequency. Predictors like age, gender, and nasal anatomical variations were analyzed. Results: The surgery group showed significant reductions in VAS scores (6.02 to 2.51, p < 0.001) and headache frequency (9.11 to 3.04, p < 0.001). The medical group did not improve significantly. All nasal subtypes improved with surgery but concha bullosa had worse VAS outcomes (4.0) than septal deviation (1.8, p < 0.001) or spur (1.73, p < 0.001). Multivariate analysis found nasal anomalies predicted postoperative VAS scores (p < 0.001) but not headache frequency (p = 0.255). Conclusions: Surgery demonstrated superiority over medications for RCPH. This study provides new evidence that preoperative CT scans should be considered a non-invasive gold standard for analyzing nasal subtypes as they significantly influence surgical success, with concha bullosa associated with worse pain relief. Larger studies should validate these findings to optimize RCPH management. Full article

Objective: We aim to construct an artificial intelligence (AI)-assisted nasal endoscopy diagnostic system capable of preliminary differentiation and identification of nasal neoplasia properties, as well as intraoperative tracking, providing an important basis for nasal endoscopic surgery. Methods: We retrospectively analyzed 1050 video data of nasal endoscopic surgeries involving four types of nasal neoplasms. Using Deep Snake, U-Net, and Att-Res2-UNet, we developed a nasal neoplastic detection network based on endoscopic images. After deep learning, the optimal network was selected as the initialization model and trained to optimize the SiamMask online tracking algorithm. Results: The Att-Res2-UNet network demonstrated the highest accuracy and precision, with the most accurate recognition results. The overall accuracy of the model established by us achieved an overall accuracy similar to that of residents (0.9707 ± 0.00984), while slightly lower than that of rhinologists (0.9790 ± 0.00348). SiamMask’s segmentation range was consistent with rhinologists, with a 99% compliance rate and a neoplasm probability value ≥ 0.5. Conclusions: This study successfully established an AI-assisted nasal endoscopic diagnostic system that can preliminarily identify nasal neoplasms from endoscopic images and automatically track them in real time during surgery, enhancing the efficiency of endoscopic diagnosis and surgery.

Background: Nasal and paranasal sinus masses can arise from a wide range of conditions, both benign and malignant, as well as congenital or acquired. Diagnosing these masses is often challenging, requiring a combination of nasal endoscopy, imaging studies, and histopathological analysis. Initial imaging frequently involves computed tomography or cone beam computed tomography (CBCT) to evaluate the bony anatomy of the nasal cavity and surrounding sinuses, while magnetic resonance imaging (MRI) is typically used for detailed assessment of soft tissues and to aid in differential diagnosis when the findings are inconclusive. Methods: This review examines nasal masses evaluated using CT, CBCT, and MRI, highlighting key imaging features that may assist in differential diagnosis. Results: For non-neoplastic lesions, examples include conditions such as rhinoliths, inverted mesiodens, and septal mucoceles. Benign and borderline tumors discussed encompass lobular capillary hemangioma, inverted papilloma, septal osteoma, chondromesenchymal hamartoma, hemangioma, hemangiopericytoma, antrochoanal polyp, sinonasal angiofibroma, ossifying fibroma, and lipoma. Malignant tumors addressed in this review include adenocarcinoma, esthesioneuroblastoma, non-Hodgkin lymphoma, melanoma, and sarcoma. Conclusions: Diagnosing nasal lesions represent a significant challenge for otolaryngologists. Imaging characteristics of nasal masses play a crucial role in narrowing down differential diagnoses before surgery. However, nasal endoscopy combined with biopsy remains the definitive diagnostic approach. 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

Background: Pituitary adenomas represent the most common pituitary disorder, with an estimated prevalence as high as 20%, and they can manifest with hormone hypersecretion or deficiency, neurological symptoms from mass effect, or incidental findings on imaging. Transsphenoidal surgery, performed either microscopically or endoscopically, allows for a better extent of resection while minimising the associated risk in comparison to the transcranial approach. Endoscopy allows for better visualisation and improvement in tumour resection with an improved working angle and less nasal morbidity, making it likely to become the preferred surgical treatment for pituitary neoplasms. The learning curve can be aided by telementoring. Methods: We retrospectively analysed the clinical records of 94 patients who underwent an endoscopic endonasal resection of a pituitary neoplasm between the years 2011 and 2023 at Maribor University Medical Centre in Slovenia. Remote surgical telementoring over 3 years assisted with the learning curve. Results: The proportion of complication-free patients significantly increased over the observed period (60% vs. 79%). A gradual but insignificant increase in the percentage of patients with improved endocrine function was observed. Patients’ vision improved significantly over the observed period. By gaining experience, the extent of gross total tumour resection increased insignificantly (67% vs. 79%). Conclusions: Telementoring for the endoscopic endonasal approach to pituitary neoplasms enables low-volume centres to achieve efficiency, decreasing rates of postoperative complications and increasing the extent of tumour resection.

Although technical causes of endoscopic sinus surgery (ESS) failure have long been reported, we were curious about the quality of contemporary sinus surgery. The electronic health database of Mayo Clinic, Arizona was scrutinized to identify adult patients with diffuse chronic rhinosinusitis (CRS) who underwent revision ESS between January 2019 and September 2023 with a history of bilateral full-house ESS. Anatomical features on preoperative radiology and intraoperative endoscopy were cataloged: residual uncinate tissue, maxillary antrostomy with a non-incorporated natural os, residual ethmoidal septations (three septations > 3 mm), and inadequate sphenoid osteotomy (os size < 6 mm). Sixty-nine subjects were identified. A deviated nasal septum was present in 53.6%. Residual uncinate tissue was noted in 50.7% of patients associated with missed natural maxillary os in 39.13% of antrostomies. An inadequate os diameter was noted in 63.8% of sphenoidotomies. Significant residual septations were seen in posterior ethmoidal cells in 66.7% and anterior ethmoidal cells in 62.3% of patients. Residual frontoethmoidal cells were noted in 72.4% of patients. Although the extent of ESS must be individualized, a high prevalence of features reflecting suboptimal surgery that could limit the success of ESS was identified. These findings merit further consideration for focused training during residency and continuous professional development activities. Full article

Rhinosinusitis in granulomatosis with polyangiitis (GPA) is categorised as a secondary, diffuse and inflammatory chronic rhinosinusitis (CRS). It is one of the conditions that impacts the nasal microbiota. This study aimed to compare the nasal microbiomes of patients with GPA, CRS and NSP. A total of 31 patients were included in the study (18 GPA, 6 CRS and 7 nasal septum perforation (NSP)). In all patients, SNOT 22, a nasal endoscopy (Lund–Kennedy scale) and a brush swab were performed. The metagenomic analysis was carried out based on the hypervariable V3-V4 region of the 16S rRNA gene. At the genus level, statistically significant differences were observed in two comparisons: the GPA/NSP and the GPA/CRS groups. In the GPA/NSP group, the differences were related to four genera (Actinomyces, Streptococcus, Methylobacterium-Methylorubrum, Paracoccus), while in the GPA/CRS group, they were related to six (Kocuria, Rothia, Cutibacterium, Streptococcus, Methylobacterium-Methylorubrum, Tepidimonas). Patients with GPA had lower diversity compared to CRS and NSP patients. There were no statistically significant differences found for the Staphylococcus family and Staphylococcus aureus between the three groups. Full article

Endoscopy-related musculoskeletal injuries (ERIs) are frequent among gastrointestinal, pulmonary, nasal, and urologic endoscopists, impacting the healthcare system. The present review aims to compare the ERI rates, risk factors, and ergonomic recommendations in the different endoscopic fields. A review was conducted using PubMed and Cochrane Library for articles based on surveys and published until 10 January 2024. Demographic, work, and ERI data from 46 publications were included, covering 10,539 responders. The ERI incidence ranged between 14% and 97%, highlighting the need of intervention independent of the specialties. The neck, back, and shoulder were the most frequent ERI locations, while gender, age, years of experience, and procedure volume the most common risk factors. Ergonomic recommendations suggest concentrating on endoscope design changes, especially in gastrointestinal endoscopy, to increase the comfort, adaptability of the equipment in the operating room, and workflow/institutional policy changes. The inclusion of an ergonomic timeout guarantees the correct equipment positioning, the neutralisation of the endoscopist’s posture, and an indirect break between procedures. Ergonomic training to increase awareness and best practice should be promoted, also using new technologies. Future research should concentrate on intervention and comparative studies to evaluate to which extent prevention measures and newly designed equipment could reduce ERI incidence. Full article

Olfactory neuroblastoma (ONB) is an uncommon neuroendocrine malignancy arising from the olfactory neuroepithelium.

Olfactory neuroblastoma (ONB) is an uncommon neuroendocrine malignancy arising from the olfactory neuroepithelium. ONB frequently presents with nonspecific sinonasal complaints, including nasal obstruction and epistaxis, and diagnosis can be obtained through a combination of physical examination, nasal endoscopy, and computed tomography and magnetic resonance imaging. Endoscopic resection with negative margins, with or without craniotomy, as necessary, is the standard of care for definitive treatment of ONB. Regional metastasis to the neck is often detected at presentation or may occur in a delayed fashion and should be addressed through elective neck dissection or radiation. Adjuvant radiotherapy should be considered, particularly in the case of high grade or tumor stage, as well as positive surgical margins. Systemic therapy is an area of active investigation in both the neoadjuvant and adjuvant setting, with many advocating in favor of induction chemotherapy for significant orbital or intracranial involvement prior to surgical resection. Various targeted immunotherapies are currently being studied for the treatment of recurrent or metastatic ONB. Prolonged locoregional and distant surveillance are indicated following definitive treatment, given the tendency for delayed recurrence and metastasis. Full article
