Objectives: Biphenotypic sinonasal sarcoma (BSNS), previously low-grade sinonasal sarcoma with neural and myogenic features, is a rare tumor of the sinonasal tract first described in 2012. Due to its rarity, limited literature is available in providing clinicians with a standardized treatment regimen, particularly in cases of positive surgical margins. This article aims to provide a clinical review of the currently available reported cases of BSNS, as well as presenting clinical, radiologic, and pathologic details of 2 novel cases. Methods: Online electronic databases include PubMed and Embase where queried for reports of biphenotypic sinonasal sarcoma or low-grade sinonasal sarcoma with neural and myogenic features. Two previously unpublished cases were included in the results. Data including clinical presentation, epidemiologic data, radiologic evaluation, intraoperative details, histopathology, treatment modality, and postoperative follow-up information were included. Results: A total of 100 previously published cases were identified in 12 prior articles. Mean age at presentation was 52.9 years. Extrasinonasal extension was observed in 27.4% of cases with most common site of extension being cribriform plate. Forty-seven cases included treatment details with surgical excision being the most common modality. Recurrence rates were identical for both surgical excision alone and surgical excision with adjuvant radiotherapy (33.3%). Conclusions: Biphenotypic sinonasal sarcoma is a slow-growing tumor that is amenable to surgical resection. Recurrence rates are similar between surgical excision and surgical excision with adjuvant radiation therapy, but limited data in reported cases preclude a determination of treatment superiority.

Purpose Since the COVID-19 pandemic began, emergency departments (ED) across the country have seen a significant decrease in patient visits. We aim to evaluate the impact of COVID-19 on ED visits for acute otolaryngologic complaints in New York City, one of the first epicenters of the pandemic in the US. Materials and methods We conducted a retrospective study of patients who presented to the ED with a primary diagnosis of an acute otolaryngologic complaint between March 1 and May 31 in 2019 and 2020. This was a multicenter study, including two tertiary care hospital systems encompassing Manhattan, Bronx, Queens, and Long Island. Results A total of 10,162 patients were identified. Significantly fewer patients presented to the ED for acute otolaryngology complaints in 2020 (7332 vs 2830, p < 0.001). The rate of total otolaryngology-related ED visits was decreased by a factor of 0.635 (95% CI 0.6079 to 0.6634). In a subgroup analysis of each individual diagnosis, there was a significant decrease in rate of ED visits for 13 out of 18 diagnoses, including for life-threatening conditions, such as anaphylaxis. There was no significant difference based on which borough in New York City. Pediatric patients (age 0–17) were more significantly impacted by the pandemic compared to other age groups. Conclusion The COVID-19 pandemic has led to a reduction in the utilization of ED for acute otolaryngologic complaints, including those requiring emergent management, and an even more significant reduction in the pediatric population. Healthcare providers should encourage patients to seek appropriate care, particularly for those illnesses with significant associated morbidity and mortality.

Objective To evaluate the efficacy of omega-3 fatty acid (O3FA) supplementation in the treatment of COVID-related olfactory dysfunction (OD). Methods Patients with laboratory-confirmed or clinically-suspected COVID-19 infection and new-onset OD from August 2020 to November 2021 were prospectively recruited. Patients with quantitative OD, defined as a brief smell identification test (BSIT) score of 9 or less, were eligible for study inclusion. The experimental group received 2 g of O3FA supplementation, while the control group received an identical placebo to be taken daily for 6 weeks. The primary outcome was a change in BSIT score between the initial and 6-week follow-up tests. Results One hundred and seventeen patients were included in the analysis, including 57 patients in the O3FA group and 60 in the placebo group. O3FA group patients demonstrated a mean BSIT improvement of 1.12 ± 1.99 compared to 0.68 ± 1.86 in the placebo group ( p = 0.221). Seventy-seven patients, 42 within the O3FA group and 35 in the placebo group, completed a follow-up BSIT survey at an average of 717.8 days from study onset. At long-term follow-up, there was an average BSIT score improvement of 1.72 within the O3FA group compared to 1.76 within the placebo group ( p = 0.948). Conclusion Among patients with persistent COVID-related OD, our study showed no clear evidence of relative short-term or long-term olfactory recovery among patients receiving high doses of O3FA supplementation.
