Background Sinonasal mucosal melanoma has poor survival despite multimodality treatment. While the impact of immunotherapy (IT) on metastatic cutaneous melanoma is well-defined, there are relatively little data on sinonasal mucosal melanoma. Objective We sought to define immunotherapy outcomes in patients with sinonasal mucosal melanoma. Methods A retrospective cohort study evaluated patients treated with IT during their overall treatment strategy for SNMM. Patient demographics, treatment, and survival outcomes were recorded. Results 52 patients had IT treatment for SNMM from 2000 to 2022, with an average age of 69.1 ± 11.9 years. The most common treatment was surgery with radiation and IT ( n = 26, 50%). Most regimens consisted of a combination of Nivolumab and Ipilimumab ( n = 17, 32.7%) or pembrolizumab ( n = 14, 26.9%). 44.2% of patients experienced reported complications. Overall survival at 1-, 2-, and 5 years was 86.9%, 74.1%, and 39.1%, respectively. Conclusion Approximately half of patients will have a local response following immunotherapy, but it is rare to have improvement at metastatic locations. Further research within our group will assess optimal timing and markers that are predictive of response.

Objective To describe the development, implementation, and validation of a radiology-administered protocol to obtain magnetic resonance imaging (MRI) in patients with cochlear implants and auditory brainstem implants without magnet removal. Study Design Retrospective review and description of novel care pathway. Methods A radiology-administered protocol was designed based on careful input from the radiology safety committee and neurotology. Radiology technologist training modules, consent instructions, patient educational material, clinical audits, and other safeguards were implemented, with samples provided in this report. The primary outcomes measured included instances of magnet displacement during MRI and premature termination of MRI studies secondary to pain. Results Between June 19, 2018, and October 12, 2021, 301 implanted ears underwent MRI without magnet removal, including 153 devices housing diametric MRI-conditional magnets, and 148 implants with conventional axial (i.e., nondiametric) magnets. Among cases with diametric MRI-conditional magnets, all studies were completed without magnet dislodgement or need to terminate imaging early due to pain. Among cases with conventional axial (nondiametric) magnets, 29 (19.6%) MRI studies were stopped prematurely secondary to pain or discomfort; the overall rate of this event was 9.6% (29 of 301) among the entire study cohort. In addition, 6.1% (9 of 148) experienced confirmed magnet displacement despite headwrap placement; the overall rate among all cases was 3.0% (9 of 301). Eight of these patients received successful external magnet reseating through manual pressure on the external scalp without surgery, and one required surgical replacement of the magnet in the operating room. There were no documented instances of hematoma, infection, device or magnet extrusion, internal device movement (i.e., gross receiver-stimulator migration), or device malfunction in this cohort related to MRI. Conclusions We present the successful implementation of a radiology-administered protocol designed to streamline care for cochlear implant and auditory brainstem implant recipients who require MRI and ease clinical demands for otolaryngology providers. Examples of resources developed, including a process map, radiology training modules, consent instructions, patient educational materials, clinical audit, and other procedural safety measures are provided so interested groups may consider adapting and implementing related measures according to need.

AbstractObjectiveTo evaluate recurrence patterns and survival after recurrence among patients with sinonasal mucosal melanoma (SNMM).MethodsThis was a multi‐institutional retrospective review from seven U.S. institutions of patients with SNMM from 1991 to 2022. Recurrence was categorized as local, regional, distant, or multifocal. Kaplan‐Meier tests were used to evaluate disease‐free survival (DFS), overall survival (OS), and post‐recurrence survival (PRS) reported with standard errors (SE) and log‐rank testing used for comparison. Cox‐regression was further used, with hazard ratios (HR) and 95% confidence intervals (CI) reported.ResultsAmong 196 patients with SNMM, there were 146 patients with recurrence (74.5%). Among all patients, 60‐month DFS (SE) was 15.5% (2.9%), 60‐month OS (SE) was 44.7% (3.7%), mean age ± standard deviation at diagnosis was 69.7 ± 12.5 years, and 54.6% were female. In 26 patients who underwent primary treatment of the neck, 60‐month DFS did not differ from no treatment (p > 0.05). Isolated distant recurrence was most common (42.8%), followed by local (28.3%), multifocal (20.7%), and regional recurrence (8.3%). Among patients with regional recurrence in the neck, there was no 60‐month PRS benefit for patients undergoing salvage neck dissection or radiation (p > 0.05). Among patients with distant recurrence, only immunotherapy was associated with improved 12‐month PRS (HR = 0.32, 95% CI = 0.11–0.92, p = 0.034), and no treatment group was associated with improved 24‐ or 60‐month PRS (p > 0.05).ConclusionSNMM is associated with a high recurrence rate and poor survival. Primary treatment of the neck was not associated with reduced recurrence, and immunotherapy for treatment of distant recurrence was associated with increased 12‐month PRS.

AbstractObjectivesDysfunction in smell or taste is well recognized phenomenon in patients infected with SARS‐CoV‐2. This study aimed to quantify the incidence and associated co‐morbidities of reported olfactory or gustatory dysfunction in patients who tested positive for SARS‐CoV‐2.MethodsFrom March 23, 2020 through July 31, 2020, 192,683 patients were tested for SARS‐CoV‐2 at Mayo Clinic. These patients with a positive test were contacted via telephone by physicians at Mayo Clinic and information gathered on patient demographics, comorbidities, symptoms and clinical risk stratification based on these factors.ResultsTwo thousand two hundred and fifty patients tested positive for SARS‐CoV‐2 (1.2%). Six hundred and sixty‐seven (29.6%) of these patients reported loss of smell or taste. Factors found to be correlated with reporting loss of smell or taste on multivariate analysis were: younger age, female sex, or symptoms of chest pain or tightness, cough, or headache and lower clinical risk category. Coronary artery disease (CAD) was associated with not reporting loss of taste or smell.ConclusionOf 2250 patients testing positive for SARS‐CoV‐2 at Mayo Clinic, 667 reported loss of taste and smell. Patients who reported loss of smell or taste were younger, female and more likely to report cough, chest pain, headache, or history of chronic obstructive pulmonary disease (COPD), but overall had fewer high‐risk comorbidities. Those who were older, male, and a reported history of CAD were less likely to report chemosensory dysfunction. Our data are the largest single institution data reporting COVID‐19 associated loss of smell or taste, and the first to associate COPD and CAD as factors that affect rates of reported chemosensory dysfunction.Level of evidenceIIB.

Objective The objective of this study is to determine the association of proliferation indices and pathologic biomarkers on overall and recurrence/metastasis‐free survival (OS and RMFS) in patients with sinonasal mucosal melanoma (SNMM) and to assess the genetic mutational landscape of SNMM. Methods This is a retrospective cohort study of 45 SNMM patients without neoadjuvant therapy who underwent surgical therapy with curative intent and had tumor tissue available for histopathologic review, molecular analysis, and genetic mutational assessment. The OS and RMFS were assessed for associations with numerous tumor and patient‐related factors. Results Among proliferative indices, higher Ki67 and mitotic rates were associated with worsened OS and RMFS (Ki67: p = 0.0007 and p < 0.0001; mitotic rate: p = 0.005 and p = 0.0009, respectively). The presence of brisk tumor‐infiltrating lymphocytes (TILs) was associated with improved RMFS ( p = 0.007) and the presence of lymphovascular invasion was associated with worsened OS and RMFS ( p = 0.02 and p = 0.04, respectively). Patients with amelanotic tumors were more likely to have higher T‐stage ( p = 0.046), less likely to have brisk TILs ( p = 0.02) and had worsened RMFS ( p = 0.03). Patients on immunotherapy with tumor Ki67 < 40% had better 3‐year OS compared to those with higher Ki67 index ( p = 0.004). Actionable genetic mutations such as BRAF V600E are rare and present in only 1 of 20 patients tested. Conclusion In SNMM patients, pathologic and proliferation markers such as Ki67, mitotic rate and brisk TILs are associated with survival and may be considered in future staging systems. Clinical response to immunotherapy appears to correlate with the Ki67 index. Given the distinct genetic profile of SNMM, targeted therapies against the MAPK kinase pathway have limited utility.

AbstractObjectivesThe purpose of this article is to provide a state‐of‐the‐art review of the literature and summarize the latest publications on medical and surgical treatment of cystic fibrosis (CF) chronic rhinosinusitis (CRS), with an emphasis on describing recent advancements in cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies.MethodsA comprehensive literature review was conducted utilizing the PubMed database with search phrases detailed within the body of the article. Abstracts were reviewed to include publications detailing medical, surgical, and CFTR modulating therapies for CF CRS. Findings from studies not previously reviewed and publications regarding CFTR modulators were emphasized.ResultsNo clear guidelines for treatment of CF CRS are available. Nasal saline rinses, topical steroids, topical antibiotics, and topical dornase alfa are reported medical therapies. Ivacaftor has some sinonasal symptomatic benefit. A new triple therapy CFTR modulator, elexacaftor/tezacaftor/ivacaftor, is capable of treating 90% of patients with CF and has shown the greatest FEV1 improvement of any CFTR modulator yet. There is no clear consensus on surgical indications or technique, though aggressive surgery in recalcitrant disease has shown some symptomatic benefit. Endoscopic sinus surgery after lung transplantation may benefit some patients in whom the sinuses serve as a reservoir for recurrent pulmonary infections by decreasing rates of bronchiolitis obliterans syndrome and improving 5 year survival.ConclusionAs lifespan increases for patients with CF, further investigation into medical therapy, CFTR modulator sinonasal outcomes, and surgical technique and outcomes for CF CRS is needed.Level of Evidence5.
