Errata and Corrigenda in the OHNS Literature.

Objectives: To analyze trends in error publication in the top Otolaryngology-Head and Neck Surgery (OHNS) journals. Methods: A retrospective bibliometric analysis utilizing journal-specific search engines of the top 30 OHNS journals (by impact factor) were queried for "errata OR erratum OR corrigenda OR corrigendum OR correction OR corrections," utilizing errors published between 2000 and 2023. Corrections were classified into "erratum" for errors originating from the journal and "corrigendum" for errors originating from the author. Error severity was categorized as trivial, minor, or major, based on the magnitude of their impact on outcomes or their interpretation by the reader. Results: Of the 739 analyzed errors, 62.5% (n = 462) were errata and 37.5% (n = 277) corrigenda, averaging 26.39 (±27.5) errors per journal. There was no correlation between impact factor and error occurrence (P = .979). Trends demonstrated growing numbers of errors published over the years. Mean duration between the publication date of the original article and the error was 10.8 months (±19.4 months), but there was no significant correlation between impact factor and this duration (P = .953). Most corrected articles were original research articles (n = 568, 76.9%), predominantly with the first author from the United States (n = 262, 36.1%). Most errors involved authorship (n = 273, 36.9%) and were "Trivial" in severity (n = 544, 73.6%). However, 72 (9.7%) errors were "Major" and altered the article's findings or interpretation significantly. Conclusion: A multitude of errors exist in the otolaryngology field. Despite most being insignificant and affecting authorship, roughly 10% significantly affect an article's conclusions/outcomes.Level of Evidence: 4.

Impact of Nutritional Status on COVID-19-Induced Olfactory Dysfunction.

OBJECTIVE: Although olfactory dysfunction is one of the most common presenting signs of COVID-19 infection, little is known about which populations are most susceptible. The aim of this study is to evaluate the risk of COVID-19-induced chemosensory dysfunction in malnourished individuals. METHODS: The N3C database was queried for adults having positive COVID-19 test result, diagnosis of chemosensory dysfunction within 2 weeks of positive test date, and overnutrition or undernutrition (i.e., deficiency or excess of micro- and macronutrients) related diagnoses prior to COVID-19 infection. Individuals previously diagnosed with chemosensory dysfunction were excluded. COVID-19-positive adults without olfactory dysfunction were similarly analyzed. Statistical analysis was performed using odds ratio calculations (95% confidence interval [CI]). RESULTS: Of 3,971,536 patients with COVID-19, 73,211 adults were identified with a diagnosis of undernutrition and 428,747 adults were identified with a diagnosis of overnutrition prior to infection. Of those with undernutrition, 264 (0.36%) individuals were identified with a diagnosis of olfactory dysfunction within 2 weeks of infection. Of those with overnutrition, 2851 (0.66%) individuals were identified with a diagnosis of olfactory dysfunction within 2 weeks of infection. The calculated odds ratio for undernutrition and olfactory dysfunction was 0.731 (p < 0.0001, 95% CI [0.0647, 0.0825]). The calculated odds ratio for overnutrition and olfactory dysfunction was 1.419 (p < 0.0001, 95% CI [1.3359, 1.5081]). CONCLUSION: Overnutrition may increase the risk of COVID-19-related olfactory dysfunction, while undernutrition may slightly protect. While reasons are unclear, baseline differences in metabolic, inflammatory, and structural biochemistry deserve closer inspection. LEVEL OF EVIDENCE: 3 Laryngoscope, 2024.

Endoscopic-Assisted Presigmoid Approach to the Internal Auditory Canal. A Feasibility Study.

HYPOTHESIS: The retrolabyrinthine (presigmoid) approach has been utilized in various skull base surgeries but has not been fully utilized in the management of internal auditory canal (IAC) lesions, such as vestibular schwannoma (VS). Microsurgical retrolabyrinthine approach provides limited visualization of the IAC, while endoscopic-assisted techniques allow for further lateral exposure with labyrinthine preservation. BACKGROUND: Traditional approaches to the IAC have the disadvantage of hearing sacrifice or retraction of brain tissue. With the introduction of endoscopic techniques and enhanced visualization, access to this region of complex anatomy is possible. METHODS: Radiomorphometric and anatomical dissection was performed on two cadaveric temporal bones. High-resolution computed tomography was used to segment and delineate the volume of the IAC. Projected accessible IAC was compared to actual postdissection data with preservation of the posterior semicircular canal (PSCC) via the retrolabyrinthine corridor. RESULTS: While preserving the PSCC, the 0° and 30° endoscopes visualized 57.1% and 78.6% of the IAC for cadaver 1, and 64.0% and 76.0% of the IAC for cadaver 2, respectively. Sacrificing the PSCC, the 0° and 30° endoscopes provided visualization of 78.6% 85.7% of the IAC for cadaver 1, and 88.0% and 95.1% of the IAC for cadaver 2, respectively. CONCLUSIONS: Retrolabyrinthine approach to resection of VS is a potentially viable hearing-preserving alternative to traditional approaches. This approach provides access to the majority of the IAC, while angled endoscopes or sacrifice of the PSCC can provide additional access toward the fundus. Further studies are needed to determine the clinical feasibility of this approach.

Increased Incidence of Vestibular Disorders in Patients With SARS-CoV-2.

Objective: Determine the incidence of vestibular disorders in patients with SARS-CoV-2 compared to the control population. Study Design: Retrospective. Setting: Clinical data in the National COVID Cohort Collaborative database (N3C). Methods: Deidentified patient data from the National COVID Cohort Collaborative database (N3C) were queried based on variant peak prevalence (untyped, alpha, delta, omicron 21K, and omicron 23A) from covariants.org to retrospectively analyze the incidence of vestibular disorders in patients with SARS-CoV-2 compared to control population, consisting of patients without documented evidence of COVID infection during the same period. Results: Patients testing positive for COVID-19 were significantly more likely to have a vestibular disorder compared to the control population. Compared to control patients, the odds ratio of vestibular disorders was significantly elevated in patients with untyped (odds ratio [OR], 2.39; confidence intervals [CI], 2.29-2.50; P < 0.001), alpha (OR, 3.63; CI, 3.48-3.78; P < 0.001), delta (OR, 3.03; CI, 2.94-3.12; P < 0.001), omicron 21K variant (OR, 2.97; CI, 2.90-3.04; P < 0.001), and omicron 23A variant (OR, 8.80; CI, 8.35-9.27; P < 0.001). Conclusions: The incidence of vestibular disorders differed between COVID-19 variants and was significantly elevated in COVID-19-positive patients compared to the control population. These findings have implications for patient counseling and further research is needed to discern the long-term effects of these findings.

COVID-19-related chemosensory changes: Findings from a prospective national database.

Objective: The aim of this study was to review findings from a large prospective national database of chemosensory disturbances associated with coronavirus disease 2019 (COVID-19) infection. Data Sources: The Virginia Commonwealth University Smell and Taste Center national database of COVID-19 chemosensory disturbances. Methods: A series of online surveys, first opened on April 10, 2020, was made accessible nationwide to any adult with sudden chemosensory dysfunction since January 2020. Participants received subsequent follow-up surveys 14 days, 1 month, 3 months, and 6 months after enrollment. An additional survey was sent to all participants on May 28, 2022 to assess long-term outcomes. Information pertaining to demographics, symptoms, comorbidities, treatments, and life impact was collected. Results: Of 363 participants who reported complete smell recovery, 51.2% recovered within 1 month, 70% within 3 months, and 79% within 6 months, while 8.8% took over 1 year to completely recover. Among all participants, 7.5% had no smell recovery. Positive predictors of recovery included age <40, male gender, and the presence of nasal congestion. Negative predictors included difficulty breathing and prior head injury. Many participants reported a decrease in quality of life and the presence of potential safety hazards associated with decreased smell loss. Conclusions: Most subjects with COVID-19-related chemosensory dysfunction recover, with the majority noting complete recovery within weeks of infection. Those aged over 40 years and female gender were associated with lower rates of recovery. A considerable number of participants reported significant impact on quality of life and safety.

Awareness campaigns for cochlear implants: Are we making an impact?

OBJECTIVE: This study aimed to determine if the major public awareness campaign for cochlear implants 'International Cochlear Implant Day' influenced national and international public interest as measured by internet search activity. METHODS: Weekly search volume data in the United States, Canada, Australia, Germany, United Kingdom, Brazil, India, Japan, and a 'Worldwide' group for the search topic 'cochlear implant' was collected from Google Trends over a 5-year period (2017-2021). The 'Campaign' window was defined as 1 week before, the week of, and 2 weeks after International Cochlear Implant Day (February 25th). 'Non-Campaign' weeks were considered any data outside the 'Campaign' window. RESULTS: Of the studied regions, the United States, United Kingdom, Australia, India, and 'Global' demonstrated a significant increase in internet search activity between 2017 and 2021. Although some individual years showed significant increases during the 'Campaign' period for Canada, Germany, Brazil, and Japan, none showed statistically significant increases over the 5-year period studied. CONCLUSION: Public awareness campaigns are recognized crucial elements to delivering effective healthcare, but their success varies worldwide. While data from Google Trends suggests that cochlear implant awareness campaigns can translate into increased internet searches, greater efforts can be made in select countries to improve public interest.

Considerations for Use of the MAUDE Database in Otolaryngology-Head & Neck Surgery Research.

The use of the US Food and Drug Administration's (FDA) Manufacturer and User Facility Device Experience (MAUDE) to analyze adverse events linked to medical devices has grown in recent years. MAUDE facilitates post-market surveillance, contributing to the assessment of device performance and the identification of potential safety concerns. The database is instrumental not only for mandatory reporters such as manufacturers and healthcare facilities but also offers a platform for voluntary submissions from clinicians and patients, thus widening the scope of data collection. While the database offers valuable data, there are important limitations that must be understood in order to encourage appropriate interpretation of findings. This commentary highlights the major advantages and disadvantages of the MAUDE database, as well as describes possible areas for improvement in adverse event reporting.
