Abstract
KEY POINTS We present the largest cohort of structured histopathology reports on primary ciliary dyskinesia-related chronic rhinosinusitis (PCD-CRS). Despite endoscopic differences, PCD-CRS and cystic fibrosis-related chronic rhinosinusitis (CF-CRS) had similar structured histopathology reports. Compared to healthy patients and those with idiopathic chronic rhinosinusitis without nasal polyps, patients with PCD-CRS had an increased neutrophil count.

Abstract
INTRODUCTION Over the last 3 years, the FDA has approved dupilumab, omalizumab, and mepolizumab for the treatment of CRSwNP; however, adverse events of these biologics have not been described in post-marketing surveillance trials. By utilizing the FDA Adverse Event Reporting System (FAERS), this study describes and compares biologic-associated adverse events in T2 disease. METHODS This case-non-case study assessed disproportionate reporting rates using reporting odds ratios (RORs). RORs and p values for biologic-associated AEs were categorized and compared among dupilumab, omalizumab, and mepolizumab. This analysis included AEs associated with all treatment indications. Relative AE rates and outcomes were calculated. RESULTS There were a total of 112,560, 24,428, and 18,741 unique AE reports associated with dupilumab, omalizumab, and mepolizumab, respectively. Omalizumab had the strongest association with anaphylaxis (ROR = 20.80, 95% confidence interval [CI]: 18.58, 23.29). Dupilumab had large relative proportions and positive signals in the ophthalmologic category (7.76%, ROR = 6.20, 95% CI: 6.06, 6.35), such as with blurry vision (ROR = 3.80, CI: 3.52, 4.12) and visual impairment (ROR = 1.98, CI: 1.80, 2.19). Dupilumab was the only biologic associated with injection-site reactions (7.98%, ROR = 8.17, 95% CI: 7.98, 8.37). DISCUSSION/CONCLUSION This is the first large-scale comparative analysis of the AE profiles of dupilumab, omalizumab, and mepolizumab. Our data suggest possible relations between dupilumab and ophthalmologic and injection-site AEs. Omalizumab was the only biologic with a positive anaphylaxis signal. This FAERS investigation suggests important AE differences among these biologics.

Abstract
Background A subset of individuals suffering from Coronavirus Disease 2019 (COVID-19) will experience ongoing symptoms that last longer than three months (i.e., long-haul COVID). This includes olfactory dysfunction (OD), which is currently estimated to occur in 1-63.5% of patients at one-year post-infection. However, OD in individuals with long-haul COVID-19 is poorly understood, and there is little information regarding how initial SARS-CoV-2 variants correlate with long-haul symptoms. In this study, we investigated the prevalence and severity of OD in patients with long-haul COVID-19 and investigated how OD severity varied with SARS-CoV-2 variants. Methods Patients were recruited from the University of North Carolina-Chapel Hill COVID Recovery Clinic. Each patient completed the University of Pennsylvania Smell Identification Test (UPSIT). The dominant strain at the time of infection was determined using the date of COVID-19 diagnosis, and Centers for Disease Control and Prevention, World Health Organization, and North Carolina Department of Health and Human Services databases. Results Nearly 85% of patients with long-haul COVID-19 reported some degree of OD, which persisted in some patients for two or more years from the date of the initial infection. There was no association between the time since COVID-19 infection and severity of OD. No difference was detected between OD in patients with long-haul COVID-19 based on the dominant variant at the time of infection (p=0.0959). Conclusion A vast majority of patients with long-haul COVID-19 had some degree of ongoing olfactory complications, although the severity of symptoms was not dependent on the dominant SARS-CoV-2 variant at the time of infection.

Abstract
Solitary plasmacytoma is a rare neoplasm characterized by localized proliferation of monoclonal plasma cells and is classified as solitary bone or solitary extramedullary plasmacytoma. Here, we present two rare cases of plasmacytoma of the head and neck. The first is a 78-year-old male who presented with a 3-month history of epistaxis and progressive obstruction of the right nasal passage. Computerized tomography (CT) imaging revealed a mass in the right nasal cavity with destruction to the maxillary sinus. An excisional biopsy was performed revealing anaplastic plasmacytoma. The second is a 64-year-old male with a past medical history significant for prostate cancer who presented with a 2-month history of left ear pain and progressive non-tender temporal swelling. A PET/CT revealed a highly avid, destructive, and lytic left temporal mass with no other evidence of distant disease. A left temporal craniectomy and infratemporal fossa dissection revealed plasma cell dyscrasia with monoclonal lambda in situ hybridization. Although plasmacytomas are uncommon tumors of the head and neck, they may mimic other entities that require different treatment. Prompt and accurate diagnosis is critical for appropriate therapeutic decisions and prognosis.

Abstract
Abstract
BACKGROUND
Although endoscopic transsphenoidal surgery (ETSS) is an established treatment for patients with nonfunctioning pituitary adenomas (NFPAs), data are limited regarding the rates and predictors of pituitary dysfunction and recovery in a large cohort of NFPA patients undergoing ETSS.
OBJECTIVE
To analyze the comprehensive changes in hormonal function and identify factors that predict recovery or worsening of hormonal axes following ETSS for NFPA.
METHODS
Among a cohort of 601 consecutive patients who underwent ETSS for NFPA between 2010 and 2018 at Washington University in Saint Louis, recovery or development of new hypopituitarism was retrospectively analyzed in 209 patients.
RESULTS
Preoperative endocrine deficits were observed in 59.8% of patients (125/209), and the deficit rates were 76.8% for male gonadal axis (86/112), 42.5% for thyroid axis, 25.8% for growth hormone axis, and 15.8% for cortisol axis. Recovery of preoperative pituitary deficit was noted in all four axes, with highest recovery in the cortisol axis with a 1-year cumulative recovery rate of 44.3%. New-onset postoperative hypopituitarism occurred most frequently in the thyroid axis (24.3%, 27/111) and least frequently in the cortisol axis (9.7%, 16/165). Multivariate analyses revealed axis-specific predictors of postoperative recovery and de novo deficiency. Older age was a negative predictor for recovery of both male hypogonadism (P= 0.04) and adrenal insufficiency (P=0.046), and a larger tumor volume was a negative predictor for recovery of hypothyroidism (P=0.043). Although higher body mass index was generally associated with any new postoperative pituitary deficit (P=0.03), most predictors of new onset deficits also differed by hormone axis.
CONCLUSIONS
Dynamic changes in pituitary hormonal levels were observed in a significant fraction of patients following ETSS in NFPA patients. The specific hormonal axis dictated postoperative endocrine vulnerability, recovery, and predictors of recovery or loss of endocrine function.

Abstract
IMPORTANCE Improvements in endoscopic technology and reconstructive techniques have made the endoscopic endonasal approach (EEA) a viable option to approach ventromedial lesions in the region of the hypoglossal canal. Prior to contemplating this surgical corridor, a thorough understanding of anatomic relationships and landmarks is essential to safely approach this region of the posterior skull base through an EEA. OBJECTIVE To describe the surgical technique and anatomic landmarks in the EEA to the hypoglossal canal through referencing nasopharyngeal and posterior skull base anatomy. DESIGN, SETTING, AND PARTICIPANTS Study of latex-injected cadaveric heads at the North Carolina Eye Bank Multidisciplinary Surgical Skills Laboratory at the University of North Carolina. INTERVENTIONS An EEA to the hypoglossal canal was carried out bilaterally in 5 embalmed, latex-injected cadaver heads. MAIN OUTCOMES AND MEASURES Cadaveric measurements of anatomic landmarks and relationships in the approach were obtained using a 10-cm surgical ruler and were reported as mean distances. Additionally, high-quality endoscopic images demonstrating the operative technique and anatomic relationships were obtained. RESULTS The distance between the lacerum segment of the internal carotid arteries, the superolateral boundary, was 23.6 mm (SD, 11.8 mm). The distance between the anterolateral edge of the occipital condyles, the inferolateral boundary, was 19 mm (SD, 0.80 mm). The supracondylar groove was identified in the same anteroposterior plane as the nasopharyngeal orifice of the eustachian tube, and the anterior-most edge of the occipital condyle was 14 mm (SD, 0.82 mm) from the posterosuperior edge of the salpingopharyngeal fold. Additionally, the transtubercular corridor was on the same plane as the superior edge of the torus tubarius in the anteroposterior axis. The distance to the hypoglossal canal from midline was 10 mm, which was found after completing drilling in the transcondylar and transtubercular corridors. Last, the hypoglossal nerve rootlets were identified entering the canal 6 mm inferiorly and 8 mm laterally from the vertebrobasilar junction. CONCLUSIONS AND RELEVANCE The eustachian tube and other elements of nasopharyngeal anatomy are fixed landmarks that provide important points of reference when approaching the hypoglossal canal through an EEA. A thorough understanding of these anatomic relationships is vital in safely navigating this direct, surgical corridor to the posterior fossa.
