RESUMEN
OBJECTIVE: To test the hypothesis that conductive hearing loss (CHL) is associated with dementia, and that middle ear reconstruction (MER) associates with improved outcomes for these measures in a multinational electronic health records database. STUDY DESIGN: Retrospective cohort study with propensity-score matching (PSM). SETTING: TriNetX is a research database representing about 110 million patients from the United States, Taiwan, Brazil, and India. PATIENTS: Subjects older than 50 years with no HL and any CHL (ICD-10: H90.0-2). Subjects of any age with and without any MER (CPT: 1010174). MAIN OUTCOME MEASURES: Odds ratios (ORs) and hazard ratios with 95% confidence intervals (95% CIs) for incident dementia (ICD-10: F01, F03, G30). RESULTS: Of 103,609 patients older than 50 years experiencing any CHL, 2.74% developed dementia compared with 1.22% of 38,216,019 patients with no HL (OR, 95% CI: 2.29, 2.20-2.37). Of patients experiencing CHL, there were 39,850 who received MER. The average age was 31.3 years, with 51% female patients. A total of 343,876 control patients with CHL were identified; 39,900 patients remained in each cohort after 1:1 PSM for HL- and dementia-related risk factors. Matched risk for developing dementia among MER recipients was 0.33% compared with 0.58% in controls (OR: 0.58, 0.46-0.72). CONCLUSIONS: CHL increases the odds for dementia, and MER improves the odds for incident dementia. This study represents the first population study on the topic of CHL, MER, and dementia.

OBJECTIVES: To test the hypothesis that surgical otologic intervention for any type of pediatric hearing loss decreases the odds for incident adverse cognitive and linguistic developmental outcomes. STUDY DESIGN: Retrospective cohort database study. METHODS: Electronic medical record data from the TriNetX Research Network were queried for children with congenital, sensorineural, conductive, and mixed hearing loss (HL) between ages 0 and 5 years. Patients were further stratified by presence (HL + surgery) or absence (HL-surgery) of surgical intervention at any point following diagnosis, including cochlear implantation, tympanoplasty with or without mastoidectomy, and tympanostomy. Primary outcomes were defined as odds for new adverse cognitive or linguistic outcomes at any point given HL treatment status [odds ratio with 95% confidence interval, (OR; 95%CI, p-value)]. Cohorts were balanced using propensity-score matching (PSM) based on US census-defined demographics and clinically relevant congenital conditions. RESULTS: Of 457,636 total patients included in the study, 118,576 underwent surgery (HL + surgery cohort) and 339,060 did not (HL-surgery). In matched cohorts, surgical otologic intervention significantly decreased the odds of developing cognitive disorders including scholastic, motor, psychological developmental disorders, and pervasive developmental delays (p < 0.01). CONCLUSIONS: Surgical interventions for treatment of pediatric HL including cochlear implantation, tympanoplasty with or without mastoidectomy, and tympanostomy should be considered as they may prevent delays in development.

OBJECTIVE: To test the hypothesis that use of cigarettes or other products with either cigarette-like smoke profile or high nicotine content by young populations increases the odds of developing sensorineural hearing loss (SNHL). STUDY DESIGN: Retrospective cohort study. SETTING: TriNetX US Collaborative Network (2003-2022). PATIENTS: Approximately 3.6 million patients at least 18 years old. INTERVENTION: None. MAIN OUTCOME MEASURES: The primary outcome of interest was diagnosis of SNHL, defined using medical billing codes ( International Classification of Diseases, Tenth Revision , Current Procedural Terminology , etc.). Cohort inclusion criteria included electronic health record entry after 2003, age 18 to 54 or 55+ years at index, and status of cigarette, noncigarette nicotine, or cannabis use. Covariates were controlled via 1:1 propensity score matching for SNHL-related conditions, including diabetes mellitus and ischemic diseases. Odds for developing SNHL were calculated against control subjects aged 18 to 54 years who have no record of nicotine/cannabis use. RESULTS: Odds for developing SNHL are higher for people 18 to 54 years old who use any nicotine product (odds ratio [95% confidence interval], 5.91 [5.71-6.13]), cigarettes only (4.00 [3.69-4.33]), chewing tobacco only (9.04 [7.09-11.63]), or cannabis only (3.99 [3.60-4.44]) compared with control. People 55+ years old who use no products also showed increased odds for SNHL (4.73 [4.63-4.85]). CONCLUSIONS: Both nicotine and smoke exposure seem to be strongly associated with increased odds for developing SNHL, with chewing tobacco having the strongest association.
