BackgroundNo study to date has analyzed the progression of sinonasal symptoms over time in COVID-19 patients. The purpose of this study is to analyze the progression of sinonasal symptoms and risk factors for olfactory dysfunction in the mild severity COVID-19 patient.MethodsAn internet survey was used to assess sinonasal symptoms in patients with COVID-19. Changes in rhinologic domain and symptom-specific Sinonasal Outcome Test (SNOT-22) scores were compared at five time points: two weeks before diagnosis, at diagnosis, two weeks after diagnosis, four weeks after diagnosis, and six months after diagnosis.Results521 responses were collected. Rhinologic domain SNOT-22 scores increased significantly (p  0.999). Taste-specific SNOT-22 scores also peaked at diagnosis (2.06, p  0.999). There were no significant differences in sense of smell or taste between 1-month and 6-month timepoints.ConclusionSinonasal symptoms, particularly loss of smell and taste, may be important presenting symptoms in the mild severity COVID-19 patient. Our findings support incorporating these symptoms into screening protocols.Level of evidence4.

Background  Outcome studies on sinonasal malignancy are limited to retrospective case series, often with inclusion of diverse histology and short follow-up. The objective of this study was to identify key predictive variables that independently impact survival for paranasal sinus squamous cell carcinoma (SCC) and adenocarcinoma (AC) and to compare these variables in the context of these two distinct clinicopathologic entities. Methods:  Analysis was conducted using the Surveillance, Epidemiology, and End Results database from 1973 to 2012 to identify key variables that impact survival for SCC and AC. Results  A total of 3,714 cases were included. There were 2,895 SCC cases and 819 AC cases. The mean age at diagnosis was 64.1 years. The male to female ratio for SCC and AC was 1.85 and 1.04, respectively. Patients with SCC and AC were most often diagnosed with stage IV disease in 61.8 and 63.4% of cases, respectively. The majority of patients received combined surgery and radiation (52% for SCC and 43.1% for AC). For SCC, increased age ( p

Objective: The recommended readability of health education materials is at the sixth‐grade level. Artificial intelligence (AI) large language models such as the newly released ChatGPT4 might facilitate the conversion of patient‐education materials at scale. We sought to ascertain whether online otolaryngology education materials meet recommended reading levels and whether ChatGPT4 could rewrite these materials to the sixth‐grade level. We also wished to ensure that converted materials were accurate and retained sufficient content. Methods: Seventy‐one articles from patient educational materials published online by the American Academy of Otolaryngology–Head and Neck Surgery were selected. Articles were entered into ChatGPT4 with the prompt "translate this text to a sixth‐grade reading level." Flesch Reading Ease Score (FRES) and Flesch‐Kincaid Grade Level (FKGL) were determined for each article before and after AI conversion. Each article and conversion were reviewed for factual inaccuracies, and each conversion was reviewed for content retention. Results: The 71 articles had an initial average FKGL of 11.03 and FRES of 46.79. After conversion by ChatGPT4, the average FKGL across all articles was 5.80 and FRES was 77.27. Converted materials provided enough detail for patient education with no factual errors. Discussion: We found that ChatGPT4 improved the reading accessibility of otolaryngology online patient education materials to recommended levels quickly and effectively. Implications for Practice: Physicians can determine whether their patient education materials exceed current recommended reading levels by using widely available measurement tools, and then apply AI dialogue platforms to modify materials to more accessible levels as needed.

Objective: Structured histopathology (SHP) is a method of analyzing sinonasal tissue to characterize endotypes of chronic rhinosinusitis with nasal polyps (CRSwNP). Allergic fungal rhinosinusitis (AFRS) shares several features with certain endotypes of CRSwNP. Our objective was to compare the histopathology of AFRS and eosinophilic CRSwNP to further understand whether they are separate endotypes or disease entities altogether. Methods: A retrospective review of AFRS and CRSwNP patients undergoing endoscopic sinus surgery was performed. Data were collected on demographics, comorbidities, subjective and objective severity scores, and 13‐variable SHP reports. CRSwNP patients with >10 eosinophils per high‐power field (eCRSwNP) were included. Chi‐squared and t‐tests were used for statistical analysis. Results: A total of 29 AFRS and 108 eCRSwNP patients were identified. AFRS patients were younger and more often Black. Symptom severity scores (SNOT‐22, Lund‐MacKay, and Lund‐Kennedy) were uniform between groups. AFRS patients had a higher rate of Charcot–Leyden crystals (41.4% vs. 10.2%; p < 0.001). Severe degree of inflammation, eosinophilic inflammatory predominance, eosinophil aggregates, subepithelial edema, and basement membrane thickening were common in both groups, and their rates were not statistically significantly different between groups. Metaplasia, ulceration, fibrosis, and hyperplastic/papillary change rates were low (<30%) and similar between groups. Conclusion: The SHP of eCRSwNP and AFRS are highly consistent, which suggests AFRS is a severe subtype of CRSwNP overall rather than a separate disease entity. This also lends credence to AFRS belonging on the endotypic spectrum of CRSwNP. Level of Evidence: 3 Laryngoscope, 134:2617–2621, 2024 [ABSTRACT FROM AUTHOR]

Objectives Ectopic olfactory neuroblastoma is an uncommon manifestation of an already rare neoplasm. We aimed to systematically review the literature for cases of ectopic olfactory neuroblastoma to better characterize this rare disease entity and to present two new case reports. Methods A search of the PubMed and Embase databases was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify English-language articles reporting cases of ectopic olfactory neuroblastoma, published from 1955 through November 2021. Results Sixty-six cases of ectopic olfactory neuroblastoma were identified in 62 articles including the current review. Ectopic olfactory neuroblastoma arose in a wide age range (2–89 years) without significant sex predilection. It occurred most commonly in the ethmoid (25%), maxillary (25%), and sphenoid (16%) sinuses. Seventy-three percent of cases presented with low Hyams grade (I and II). The most common symptoms were nasal obstruction (32%) and epistaxis (32%). Paraneoplastic syndromes were observed in 27% of patients. The most common treatment was surgical resection followed by adjuvant radiotherapy. Overall, 76% of all patients were disease-free at the time of last follow-up. Locoregional recurrences and distant metastases were found in 19 and 5% of cases, respectively. Conclusion This systematic review describes previously reported cases of ectopic olfactory neuroblastoma, a disease entity with poorly understood characteristics. Physicians should consider olfactory neuroblastoma in the differential diagnosis for sinonasal masses, as their ectopic presentation may present considerable diagnostic and therapeutic difficulties. Patients with olfactory neuroblastoma may benefit from long-term follow-up and routine endoscopic examinations for surveillance of ectopic recurrences. [ABSTRACT FROM AUTHOR]

Objective: To analyze clinical and radiographic features that may impact the rate of focal hyperostosis (FH) on computed tomography (CT) for primary and recurrent sinonasal inverted papillomas (IPs) as well as highlight factors that may affect concordance between FH and IP true attachment point (TAP). Methods: All IPs resected between 2006 and 2022 were retrospectively reviewed. CTs were read by a neuroradiologist blinded to operative details. IP with malignancy was excluded. Operative reports and long‐term follow‐up data were evaluated. Results: Of 92 IPs, 60.1% had FH, 25% had no CT bony changes, and 20.7% were revision cases. The recurrence rate for rhinologists was 10.5% overall and 7.3% for primary IPs. Primary and revision IPs had a similar rate of FH (63% vs. 52.6%; p = 0.646) and FH–TAP agreement (71.7% vs. 90%; p = 0.664). Nasal cavity IPs, especially with septal attachment, were more likely to lack bony changes on CT (57.1%) compared to other subsites (p = 0.018). Recurrent tumors were 16 mm larger on average (55 mm vs. 39 mm; p = 0.008). FH (75.0% vs. 60.9%; p = 0.295), FH–TAP concordance (91.7% vs. 74.4%; p = 0.094), and secondary IP (18.8% vs. 20.3%; p = 0.889) rates were similar between recurrent and nonrecurrent tumors. Conclusion: Primary and revision IPs have a similar rate of FH and FH–TAP agreement. Nasal cavity IPs are less likely to exhibit bony CT changes. Lower recurrence was associated with smaller size and fellowship training but not multiple TAPs, revision, FH absence, or FH–TAP discordance.
