The relationship between survey-based subjective olfactory awareness and objective olfactory function.

KEY POINTS: Correlation between symptom-based surveys and objective olfactory testing is variable. For diagnosis and symptom monitoring, surveys should correlate with objective testing. The Odor Awareness Scale (OAS) and Affective Importance of Odor Scale (AIO) showed significant but moderate positive correlations with University of Pennsylvania Scent Identification Test (UPSIT) score.

The Surprising Effect of Priming on SNOT-22 Results.

BACKGROUND: Priming is a psychological phenomenon where subconscious cues in the environment impact our behavioral responses in certain situations. Well studied in the worlds of business, marketing, and even politics, it is unclear how the priming phenomenon impacts patient perception of their own disease state nor how they report that perception using tools like the Sinonasal Outcomes Test (SNOT-22), used to measure that perception in chronic rhinosinusitis. OBJECTIVE: To determine the impact of positive or negative priming on self-reported patient perception of their chronic rhinosinusitis disease using the SNOT-22 disease-specific quality of life instrument. METHODS: Single-blind, randomized, prospective cohort pilot study of 206 consecutive adult patients with a clinical diagnosis of chronic rhinosinusitis presenting to a university rhinology clinic. Patients were randomized to receive "positive priming" (103) or "negative priming" (103) by reading a passage about the positive or negative aspects of chronic sinusitis and its treatment respectively. Patients were then asked to fill out the SNOT-22 and results between the two groups were compared. RESULTS: The negative priming group had a higher median SNOT-22 score of 49 [IQR = 39] compared to the positive priming groups' score of 22 [IQR = 27], p < 0.0001), a difference of nearly three times the minimal clinical impactful difference (MCID). This effect was consistent regardless of age or sex of the patient. Subgroup analysis revealed a greater impact when priming was performed by the senior male attending regardless of patient age or sex (p < 0.001), while priming performed by the younger female research fellow had greater impact on older patients (>59 years, p = 0.001) and female patients (p = 0.003). CONCLUSIONS: Priming impacts how patient's perceive their chronic rhinosinusitis as determined by the SNOT-22. It is imperative that the rhinologist understand this when using this instrument in research applications and in clinical decision-making for patients.

"Left on their own": Left-handedness among rhinologists and otolaryngology trainees.

KEY POINTS: Left-hand-dominant (LHD) respondents reported higher rates of training difficulties because of handedness differences. LHD respondents cited particular difficulty with functional endoscopic sinus surgery. Both LHD and right-hand-dominant respondents perceived a need for laterality-specific training during residency.

Characterizing Adverse Events of Biologic Treatment of T2 Disease: A Disproportionality Analysis of the FDA Adverse Event Reporting System.

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.

Histologic characterization of primary ciliary dyskinesia chronic rhinosinusitis.

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.

Vascular Loop of the Anterior Inferior Cerebellar Artery (AICA) as a Cause of Sensorineural Hearing Loss (SNHL): A Case Report.

Sensorineural hearing loss (SNHL) is one of the most common causes of hearing loss worldwide. Although highly prevalent, many patients often present with SNHL of unknown cause. Related to SNHL is tinnitus, which often presents with SNHL and can have debilitating effects on patients. The idiopathic nature of SNHL and tinnitus often makes treatment difficult, however, a relatively new etiology has been suggested as a cause of SNHL and tinnitus -- vascular loops within the internal auditory canal (IAC). This report presents the case of a 36-year-old male with bilateral SNHL and tinnitus treated with oral steroids. The patient reported subjective improvement of hearing loss and tinnitus, and the audiogram demonstrated hearing improvement, except in higher frequencies. After initial treatment, MRI revealed a vascular loop of the anterior inferior cerebral artery (AICA) in the right IAC, in contact with the vestibulocochlear nerve. Thus, this case report seeks to present a conservative strategy for SNHL and tinnitus in the presence of a vascular loop of the AICA. As a controversial cause of SNHL and tinnitus, there is no standard of treatment for AICA loops of the IAC which are often treated surgically. This case highlights the importance of an initial conservative prior to surgical intervention. Thus, we seek to contribute to the growing body of literature by further elucidating the relationship between SNHL, tinnitus, and vascular loops and discussing potential pathophysiological mechanisms to guide optimal management strategies.

Characteristics of olfactory dysfunction in patients with long-haul covid-19.

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.

Plasmacytoma of the Head and Neck: Case Series and Review of the Literature.

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.

Sinonasal quality of life in primary ciliary dyskinesia.

KEY POINTS: Our findings suggest that primary ciliary dyskinesia (PCD)-related chronic rhinosinusitis (CRS) has a more significant impact on quality of life than CRS without nasal polyps and cystic fibrosis (CF). PCD and CF have similar mucociliary clearance defects, yet sinonasal symptom severity varies between the two.

Granulomatosis With Polyangiitis Presenting as an Infratemporal Fossa Mass.

Granulomatosis with polyangiitis is a rare autoimmune disease that affects small to medium-sized blood vessels throughout the body. Here, we present a case of an infratemporal mass that was the result of granulomatosis with polyangiitis. A 51-year-old male presented to the emergency department due to right cheek and facial pain that he had been experiencing for 2 to 3 months. An MRI revealed a mass within the right infratemporal and pterygopalatine fossae extending into the inferior right orbital fissure along the maxillary division of the trigeminal nerve (V2) and the vidian nerve causing concern for malignancy. Histology from an endoscopic biopsy demonstrated multiple arteries with luminal obliteration with non-necrotizing granulomas. The patient was started on steroids and immunosuppressive therapy, which improved his symptoms and decreased the size of the residual mass. This case illustrates the need for laboratory testing, imaging, and biopsy of the involved tissue in cases where GPA is suspected to prevent treatment delays that could lead to the destruction of vital organs.

"Hole-Punch" Technique for Recurrent Auricular Hematomas.

Effective treatment of auricular hematomas can be a challenging problem for both the otolaryngologist and the patient. Recurrence rates are high even with proper drainage and bolstering. The hole-punch technique is a powerful tool to address the difficult problem of recurrent auricular hematomas and avoid disfiguring deformities of the ear. Laryngoscope, 133:814-817, 2023.

Mental health burden of empty nose syndrome compared to chronic rhinosinusitis and chronic rhinitis.

BACKGROUND: Empty nose syndrome (ENS) is characterized by the paradoxical perception of nasal obstruction despite patent sinonasal anatomy after surgery. We investigated the relationship between ENS, and anxiety, depression, obsessive-compulsive disorder, and somatic symptom disorder (SSD) compared to individuals with chronic rhinitis (CR) and chronic rhinosinusitis (CRS). METHODS: This cross-sectional survey study compared ENS and CR and CRS patients. A total of 116 patients participated: 58 ENS patients from digital support groups, and 58 CRS and CR patients from tertiary rhinology clinics. Study participants completed four validated surveys: (1) Empty Nose Syndrome 6-Item Questionnaire, (2) Rhinosinusitis Disability Index (RSDI), (3) Obsessive Compulsive Inventory - Revised (OCI-R), and (4) PRIME MD Patient Health Questionnaire (PHQ). RESULTS: ENS patients exhibited a mean RSDI of 78.6, 95% confidence interval [CI] 72.8-84.5, compared to 25.2, 95% CI 18.6-31.8 for CRS/CR patients (p < 0.0001). This difference was seen across all subdomains. Using the PHQ, 53% of ENS patients met diagnostic thresholds for SSD compared to 14% of CRS patients (p < 0.0001). In relation to obsessive compulsive disorder (OCD), 18.37% of ENS patients compared to 8.62% of CRS/CR patients scored above the diagnostic threshold (>21) on the OCI-R questionnaire (p = 0.159). CONCLUSION: ENS patients had diminished sinonasal quality of life and a higher prevalence of comorbid anxiety and depression, compared to CR and CRS. ENS patients were more likely to exceed thresholds for OCD and SSD compared to controls. Future studies are needed to assess the role of SSD in ENS to help optimize treatment for these complex patients.
