Predictors of Subjective Olfactory Dysfunction and Sinonasal Quality-of-Life After Endoscopic Transsphenoidal Pituitary Surgery.

BACKGROUND: This is the largest study in North America investigating olfactory outcomes after pituitary surgery to date. OBJECTIVE: Characterize factors associated with subjective olfactory dysfunction (OD) and worsened sinonasal quality-of-life (QOL) after endoscopic TSA. METHODS: Patients undergoing primary TSA for secreting and non-secreting pituitary adenomas between 2017 and 2021 with pre- and post-operative SNOT-22 scores were included. Subjective OD was determined by the smell/taste dysfunction question on the SNOT-22 (smell-SNOT). RESULTS: 159 patients with pre- and post-operative SNOT-22 scores were included. Average total SNOT-22 scores worsened from pre-operative (16.91 ± 16.91) to POM1 (25.15 ± 20.83, P < .001), with no difference from pre-operative (16.40 ± 15.88) to POM6 (16.27 ± 17.92, P = .936) or pre-operative (13.63 ± 13.54) to POM12 (12.60 ± 16.45, P = .651). Average smell-SNOT scores worsened from pre-operative (0.40 ± 1.27) to POM1 (2.09 ± 2.01, P < .001), and pre-operative (0.46 ± 1.29) to POM6 (1.13 ± 2.45, P = .002), with no difference from pre-operative (0.40 ± 1.07) to POM12 (0.71 ± 1.32, P = .100). Female gender had a 0.9-point (95% CI 0.1 to 1.6) P = .021, increase in smell-SNOT at POM1, resolving by POM6 (0.1 [-0.9 to 1.1], P = .800) and POM12 (0.0 [-1.0 to 0.9], P = .942). Septoplasty with tunnel approach had a 1.1 [0.2 to 2.0] out of 5-point (P = .023) increase in smell-SNOT at POM1, resolving by POM6 (0.2 [-1.1 to 1.6], P = .764) and POM12 (0.4 [-0.9 to 1.6], P = .567). Female gender had a 9.5 (4.0 to 15.1)-point (P = .001) increase in SNOT-22 scores at POM1, resolving by POM6 (3.4 [-3.0 to 9.8], P = .292) and POM12 (6.4 [-5.4 to 18.2], P = .276). Intra-operative CSF leak had an 8.6 [2.1 to 15.1]-point (P = .009) increase in SNOT-22 scores at POM1, resolving by POM6 (5.4 [-1.7 to 12.5], P = .135), and POM12 (1.1 [-12.9 to 15.1], P = .873). CONCLUSION: Changes in subjective olfaction and sinonasal QOL after TSA may be associated with gender, operative approach, and intra-operative CSF leak, resolving 6-12 months post-operatively.

Stellate ganglion block for treating post-COVID-19 parosmia.

BACKGROUND: Post-COVID parosmia may be due to dysautonomia and sympathetic hyperresponsiveness, which can be attenuated by stellate ganglion block (SGB). This study evaluates SGB as a treatment for post-COVID olfactory dysfunction (OD). METHODS: Retrospective case series with prospective data of patients with post-COVID OD undergoing unilateral (UL) or bilateral (BL) SGB. Patients completed Brief Smell Identification Tests (BSIT) (12 points maximum) and post-procedure surveys including parosmia severity scores on a scale of 1 (absent) to 10 (severe). Scores were compared from before treatment (pre-SGB) to after first (SGB1) or second (SGB2) treatments in overall, UL, and BL cohorts. RESULTS: Forty-seven patients with post-COVID OD underwent SGB, including 23 UL and 24 BL. Twenty patients completed pre- and post-SGB BSITs (eight UL and 12 BL). Twenty-eight patients completed postprocedure surveys (11 UL and 17 BL). There were no differences in BSIT scores from pre-SGB to post-SGB1 or post-SGB2 for the overall (p = 0.098), UL (p = 0.168), or BL (p = 0.230) cohorts. Parosmia severity for the overall cohort improved from pre-SGB (8.82 ± 1.28) to post-SGB1 (6.79 ± 2.38) and post-SGB2 (5.41 ± 2.35), with significant differences from pre-SGB to post-SGB1 (p < 0.001) and pre-SGB to post-SGB2 (p < 0.001), but not post-SGB1 to post-SGB2 (p = 0.130). Number of parosmia triggers decreased for overall (p = 0.002), UL (p = 0.030) and BL (p = 0.024) cohorts. Quality of life (QOL) improved for all cohorts regarding food enjoyment, meal preparation, and socialization (p < 0.05). CONCLUSION: SGB may improve subjective parosmia and QOL for patients with post-COVID OD, however it may not affect odor identification. Further placebo-controlled studies are warranted.

Patient Insights into the Diagnosis of Smell and Taste Disorders in the United States.

OBJECTIVES: Diagnosis of smell/taste dysfunction is necessary for appropriate medical care. This study examines factors affecting testing and diagnosis of smell/taste disorders . METHODS: The online USA Smell and Taste Patient Survey was made available to US patients with smell/taste disorders between April 6-20, 2022. 4,728 respondents were included. RESULTS: 1,791 (38%) patients reported a documented diagnosis. Patients most often saw family practitioners (34%), otolaryngologists (20%), and Taste/Smell clinics (6%) for smell/taste dysfunction. 64% of patients who went to Taste/Smell clinics received smell testing, followed by 39% of patients who saw otolaryngologists, and 31% of patients who saw family practitioners. Factors associated with increased odds of diagnosis included age (25-39 years (OR 2.97, 95% CI [2.25, 3.95]), 40-60 (OR 3.3, 95% CI [2.56, 4.52]), and >60 (OR 4.25, 95% CI [3.21, 5.67]) vs. 18-24 years), male gender (OR 1.26, 95% CI [1.07, 1.48]), insurance status (private (OR 1.61, 95% CI [1.15, 2.30]) or public (OR 2.03, 95% CI [1.42, 2.95]) vs. uninsured), perception of their family practitioner to be knowledgeable (OR 2.12, 95% CI [1.16, 3.90]), otolaryngologic evaluation (OR 6.17, 95% CI [5.16, 7.38]), and psychophysical smell testing (OR 1.77, 95% CI [1.42, 2.22]). CONCLUSION: Psychophysical testing, otolaryngologic evaluation, patient assessment of family practitioner knowledge level, insurance, age, and gender are significant factors in obtaining smell/taste dysfunction diagnosis. This study identifies barriers to diagnosis including lack of insurance or access to specialist evaluation and highlights the importance of educating family practitioners in diagnosis and management of patients with smell/taste disorders.

The Role of Gender-Concordant Mentorship in Women Premedical Students' Perception and Pursuit of Surgical Careers.

OBJECTIVE: Evaluate the impact of a 6-month structured mentorship program between women premedical student mentees paired with women medical students and surgical residents on mentees' interests and perceptions of surgical careers. DESIGN: Prospective qualitative and quantitative study. SETTING: This study took place at the Boston University School of Medicine, a single institution tertiary care hospital. PARTICIPANTS: Self-identified women premedical students at Boston University were eligible for inclusion in this program (n=90). Participants were recruited and grouped with self-identified women medical student (n=52) and resident (n=19) mentors. Participants were provided with a monthly curriculum to guide discussions. Mentees completed pre- and postprogram surveys with 5-point Likert scale questions regarding interest and exposure to surgery, role models and mentorship, and effect of COVID-19 on their career interests. Pre- and postprogram responses were compared using a Wilcoxon rank sum test. RESULTS: Of the 90 mentees, 63 (70%) completed preprogram surveys, and 53 (59%) completed postprogram surveys. Survey respondents indicated statistically significant increased exposure to positive role models (preprogram mean 3.15, postprogram mean 4.06, p=0.0003), increased exposure to women role models (preprogram 2.30, postprogram 3.79, p<0.0001), increased access to dedicated mentors (preprogram 2.11, postprogram 3.75, p<0.0001), and increased availability of support persons to answer their questions and concerns about careers in surgery (preprogram 3.03, postprogram 3.85, p=0.001). There was also a statistically significant increase in the reported effect that exposure to gender-concordant role models in surgery had on participants' decisions to consider a surgical career (preprogram 3.58, postprogram 4.23, p=0.001). CONCLUSION: This 6-month structured mentorship program for undergraduate premedical students increased mentees' exposure to positive women role models and mentors, and increased mentee's interest in pursuing a surgical career. This emphasizes the need for structured gender-concordant mentorship programs early in women's careers to encourage pursuit of surgical careers in an otherwise men-dominated field.

Otolaryngologic conditions in children with neonatal abstinence syndrome: A descriptive study.

PURPOSE: Literature on otolaryngologic sequelae of children with neonatal abstinence syndrome (NAS) has been scarce to date. Prior reports suggest some otologic conditions associated with long-term NAS outcomes, but no comprehensive exploration of these relationships currently exists. This study aims to characterize the breadth of otolaryngologic conditions diagnosed in children with NAS. METHODS: This is a retrospective descriptive study conducted at a tertiary care hospital. We identified 524 children with NAS born between 1/1/2014 and 12/31/2019 who were evaluated by the otolaryngology department. Diagnoses were categorized as otologic, oropharyngeal, sinonasal, and laryngeal. Additional diagnoses of obstructive sleep apnea (OSA) and congenital abnormalities of head and neck were noted separately. Descriptive statistics were calculated, and ANCOVA testing analyzed for differences in mean number of diagnoses. RESULTS: 680 total otolaryngologic diagnoses were analyzed across 524 patients. Otologic conditions comprised 39.7 % of total diagnoses, oropharyngeal conditions 26.8 %, sinonasal conditions 18.4 %, laryngeal conditions 5.3 %, OSA 1.5 %, and congenital abnormalities 8.3 %. After adjusting for covariates, there were a significantly higher number of otologic diagnoses compared to the other subcategories with mean (standard deviation) of 0.46 (0.83), followed by oropharyngeal 0.35 (0.55), sinonasal 0.24 (0.49), and laryngeal 0.07 (0.29). Thirty total otolaryngology-related procedures were performed in our sample, with myringotomy with tube insertion as the most common. CONCLUSION: Understanding the otolaryngologic sequelae of children with NAS is important as these conditions impact children's early development. Our study also highlights various socioeconomic factors that may impact pediatric ENT care and the follow-up of patients born with NAS.
