RESUMEN
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.
RESUMEN
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.
RESUMEN
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.

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.
RESUMEN
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.
RESUMEN
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.
RESUMEN
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.

STUDY OBJECTIVES: Poor sleep is a prevalent complaint in the population with chronic tinnitus, but the relationship between the two is not well-characterized. The objective of this study was to understand how subjective and objective measures of sleep compare in patients with or without chronic tinnitus. METHODS: This prospective cohort study included consecutive adult patients who presented to a sleep laboratory between January 19, 2017, and January 10, 2020. All patients underwent an in-laboratory nocturnal polysomnogram and filled out questionnaires including the Pittsburgh Sleep Quality Index (PSQI), Tinnitus Screener, and Tinnitus Handicap Inventory, among others. RESULTS: The study included 1,968 participants, out of which 284 (14.4%) reported chronic tinnitus. Patients with chronic tinnitus were younger (51.6 years vs 54.1 years; P < .05) and more likely female (16.4% vs 11.7%; P < .005). They demonstrated worse subjective sleep quality (PSQI: 11.3 vs 9.5; P < .0005) and increased sleepiness (Epworth Sleepiness Scale: 9.8 vs 8.6; P < .005). In the objective sleep parameters only the total sleep time was increased in chronic tinnitus (311.5 vs 294.5 minutes; P < .05) and total arousals were decreased (41.7 vs 47; P < .005). Sleep stage N3 was higher in those with chronic tinnitus (14.9% vs 13.0%; P < .05). In multivariable analyses, as PSQI increases the odds of chronic tinnitus increases. This effect was modified by age: In those younger than 55 years of age, the odds of the presence of chronic tinnitus was 1.10 (95% confidence interval, 1.03, 1.17) times higher as PSQI increased. CONCLUSIONS: Chronic tinnitus is associated with significant changes in qualitative sleep (higher PSQI) but no major differences in quantitative sleep measures were observed.

PURPOSE: To explore anatomic predictors of mortality from gunshot wounds involving the temporal bone. METHODS: A retrospective search of radiology reports was performed for all patients with CT reports suggestive of gunshot wounds (GSW) to the TB (2000-2020). All cases were reviewed by the senior author to confirm injury to the temporal bone. Detailed demographic and radiographic data were collected. MAIN FINDINGS: A total of 120 patients met inclusion criteria. The majority of patients were male (n = 101) and the average age was 32.9. The squamosa was the most commonly involved subsite (n = 90), followed by the mastoid (n = 43). Squamosal entry site had the highest associated mortality (89.7 %). For those with known disposition, 65.8 % (79 of 120) expired on the same hospital admission. Inpatient otolaryngology consultation was noted in 18.3 % (n = 22) of patients, with poor outpatient follow-up. CONCLUSIONS: This series represents the largest survey of GSW to the temporal bone to date. Although associated mortality is high and outpatient follow-up poor, otolaryngologists should be aware of associated morbidities to facilitate both inpatient and subsequent outpatient management.

INTRODUCTION: Pulsatile tinnitus (PT) occurs in many but not all patients with idiopathic intracranial hypertension (IIH). It is poorly understood why some patients with IIH develop PT, yet others do not. The purpose of this study was to determine if any clinical findings differ between those with and without PT in IIH, potentially shedding light on a pathophysiologic mechanism. METHODS: Age-matched cohort analysis of patients with documented IIH and presence or absence of PT was performed, collecting data including body mass index (BMI), blood pressure, visual acuity, cerebrospinal fluid (CSF) opening pressure, sleep apnea, migraines, and transient visual obscurations, among others. Independent-sample t test and χ2 test were used to analyze continuous and binary variables, respectively, with multivariate analysis conducted including variables statistically significant on univariate analysis. RESULTS: Eighty subjects with IIH met the inclusion criteria (40 PT+, 40 PT-). CSF opening pressure showed no significant difference between the two groups. The PT+ cohort was found to have an average BMI of 45.1 kg/m 2 , which was significantly higher than the PT- group (37.7 kg/m 2 ; p = 0.0023). PT+ pulse pressure (60.1 mm Hg) was also significantly higher than the PT- group (51.6 mm Hg; p = 0.019). PT+ patients were also significantly more likely to have sleep apnea ( p < 0.001) and migraines ( p = 0.0036). Multiple logistic regression revealed an adjusted odds ratio of 13.9 for sleep apnea, 4.1 for migraines, and 1.01 for every increase in unit of BMI. CONCLUSION: Among patients with IIH, presence of PT is associated with higher BMI and pulse pressure, and increased incidence of sleep apnea and migraines. Given no significant difference in CSF pressures between the two groups, PT may not be a product of increased disease severity but may be related to sequelae of obesity, such as increased pulse pressure and sleep apnea.

INTRODUCTION: There is a paucity of data reporting the rate of chorda tympani nerve injury during cochlear implantation (CI) surgery. To better provide clarity to patients and surgeons regarding the risk of taste change, we performed a systematic review and meta-analysis of prospective studies examining taste change after CI. DATA SOURCES: PubMed, Embase, and Cochrane Library databases were queried. METHODS: Databases were queried according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Search terms included "(chorda tympani OR gustatory OR taste OR chemosensory OR dysgeusia OR nervus intermedius) AND (cochlea OR cochlear implant OR cochlear implantation)." Prospective studies were included and further divided into "objective" and "subjective" assessments of taste dysfunction. A systematic review was performed for all studies. A random-effects model was used to compare studies with similar methods and patient demographics. RESULTS: The initial database query yielded 2,437 articles, which were screened according to inclusion and exclusion criteria. Nine appropriate studies were identified, including 442 total patients-254 with subjective assessment and 271 with objective assessment of gustation. Seventeen of 144 patients (11.8%) reported short-term taste change (incidence = 0.09 [0.02-0.16], 95% confidence interval with pooled data). Twenty-six of 265 patients (9.8%) reported long-term taste change (incidence = 0.07 [0.01-0.13]). Objective results were heterogenous and therefore not amenable to pooled meta-analysis. CONCLUSIONS: Taste change from chorda tympani nerve injury is a likely underrecognized complication of CI and may be the most common adverse consequence of CI surgery. Surgeons should counsel prospective patients on this potential complication and that the risk of taste change may persist longer than the immediate postoperative period.

BACKGROUND: Cochlear implantation (CI) has long been the standard of care for patients with severe-to-profound hearing impairment. Yet the benefits of CI extend far beyond speech understanding, with mounting recent literature supporting its role in tinnitus abatement. However, those studies have uniformly analyzed the effects of tinnitus after the traditional 3-4 weeks waiting period between CI surgery and device activation. As many clinics are shifting these waiting intervals to become shorter (in some cases within 24 hours, little is known about tinnitus abatement very early in the postoperative period. The aim of this study was to compare preoperative and postoperative tinnitus handicaps in this unique but growing population of very early-activated patients. METHODS: Twenty-seven adults with severe-to-profound hearing impairment with chronic tinnitus (>6 months) were included. Patients with concomitant psychiatric disorders were excluded. All patients were implanted with the same array and were switched on within 24 hours after the surgery. Tinnitus Handicap Inventory (THI) was recorded preoperatively, immediately after activation at 24 hours postoperatively, at 1 week, 2 weeks, and I month after activation. Wilcoxon signed-rank test was used to compare values between preoperative assessment and respective fitting sessions. RESULTS: Mean THI 24 hours after implantation increased in comparison to that assessed preoperatively (77.6 vs 72.5, p = 0.001). By 1 week after surgery, the THI had decreased to 54.9 ( p < 0.001). This trend continued and was statistically significant at 2 weeks (36.0, p < 0.001) and 1 month (28.5, p < 0.001). CONCLUSION: On average, most patients with tinnitus will note a significant improvement in their tinnitus handicap when activated within 24 hours of CI. However, tinnitus does increase between surgery and 24 hours, most likely reflecting not only intracochlear changes, but modulation of the entire auditory pathway. Following this early rise, the tinnitus continues to abate over the following month. Patients with tinnitus may benefit from early activation, although should be counseled that they may experience an exacerbation during the very early postoperative period.

Chemosensory losses have long been considered a cardinal symptom of COVID-19 infection. Recent studies have shown changing symptom profiles with COVID-19, including decreasing incidence of olfactory losses. We accessed the National COVID Cohort Collaborative database to identify patients with and without smell and taste loss within 2 weeks of COVID-19 diagnosis. Peak prevalence time intervals for variants were determined from Covariants.org. Using rates of chemosensory loss during the peak time interval for "Untyped" variants as baseline (4/27/2020-6/18/2020), odds ratios for COVID-19-associated smell or taste disturbance fell for each of the Alpha (0.744), Delta (0.637), Omicron K (0.139), Omicron L (0.079), Omicron C (0.061), and Omicron B (0.070) peak intervals. These data suggest that during the recent Omicron waves and potentially moving forward, the presence or absence of smell and taste disturbances may no longer have predictive value in the diagnosis of COVID-19 infection.

OBJECTIVE: Many but not all patients with idiopathic intracranial hypertension (IIH) have pulsatile tinnitus (PT). However, little is known about why some patients with IIH develop PT and others do not. The purpose of this study was to determine if any of the classic magnetic resonance imaging (MRI)-detectable markers of IIH differ between patients with and without PT, thereby shedding light on potential pathophysiology. METHODS: A retrospective age-matched cohort study of patients with documented IIH (diagnosed by neuro-ophthalmologist) was performed. All patients had MRI performed around the time of diagnosis. MRIs were assessed for 16 variables known to be associated with IIH (e.g., pituitary displacement/empty sella, optic nerve tortuosity, transverse sinus stenosis, inferior cerebellar tonsils, arachnoid granulations, slit-like ventricles) by two blinded neuroradiologists. All binary variables were analyzed via χ2 test with Yates correction, or Fisher exact when appropriate. Continuous variables were analyzed via Student t test. Inter-rater reliability for binary variables was assessed by Cohen κ . For continuous variables, intraclass correlation coefficient was calculated. RESULTS: Forty age-matched patients with IIH met the inclusion criteria (20 with PT, 20 without PT). For all known binary MRI findings associated with IIH, there were no statistically significant differences between groups. Likewise, there were no statistically significant differences for continuous variables. CONCLUSIONS: The classic MRI findings associated with IIH do not differ between patients with and without PT, suggesting that systemic (rather than localized intrinsic or extrinsic) factors may play a critical role in the pathophysiology.

OBJECTIVE: To determine if public awareness campaigns in Otolaryngology-Head and Neck Surgery are influencing public interest, as measured by internet searches. STUDY DESIGN: Database Query. SETTING: Internet. METHODS: Six awareness campaigns were analyzed over 5 years (2016-2020). Each campaign was assigned one or more relevant Google search terms/topics. Weekly data on United States internet search queries for these topics/terms were collected from Google Trends. "Campaign" dates were defined as 1 week before and 2 weeks after any awareness "day" or "week," and 2 weeks prior and 2 weeks after any awareness "month." "Non-campaign" weeks were considered any data outside the "campaign" window. A Welch's unpaired t-test was used to determine statistically significant differences between "campaign" dates and "non-campaign" dates. RESULTS: Of the awareness campaigns studied, only "Kids ENT Health Month" (search topic "adenoidectomy," P = < .001) and "Cochlear Implant Day" (search topic "cochlear implant," P = .004615) demonstrated a significant increase in internet search activity during the time frame of interest between 2016 and 2020. Although there were some individual years with significant increases for select search terms/topics corresponding to their campaign of interest, none of the campaigns showed increases over the 5-year period studied. CONCLUSION: Public health advocacy and outreach has long been recognized as an important component of optimizing otolaryngologic care. However, such efforts to increase public awareness may have varying or even minimal impact. Though an imperfect tool, data from Google Trends suggests that with few exceptions, awareness campaigns in otolaryngology do not necessarily translate to increased internet searches.

OBJECTIVE AND IMPORTANCE: With an aging population and increasing utilization of both cochlear implants (CI) to treat hearing loss and deep brain stimulation (DBS) to treat neurodegenerative movement disorders, more patients will be sequentially implanted with the two devices. As such, understanding both presurgical evaluations and surgical procedures will be of great importance to the treating cochlear implant surgeon and neurosurgeon in optimizing outcomes for both conditions. CLINICAL PRESENTATION: Two illustrative cases of sequential CI followed by DBS are reviewed. Relevant pre-, intra-, and postoperative issues are discussed for both DBS following CI surgery and CI following DBS surgery. CONCLUSION: Despite the potential for challenges, sequential CI and DBS (and vice versa) can provide substantial benefit to those individuals with severe hearing loss and movement disorders. A thorough understanding of both devices is critical to ensuring optimal outcomes.
