Tinnitus is, in fact, the most prevalent military service-connected disability. There is no cure for tinnitus, but interventions are available to help patients manage their reactions to tinnitus and reduce its functional impact. Progressive tinnitus management (PTM) is a stepped-care protocol that involves coordinated audiological and behavioral health clinical services.

Younger age, low viscosity of the middle ear fluid, and female sex were associated with an increased risk of false peaked 226-Hz tympanograms despite MEE. Furthermore, larger equivalent outer ear canal volumes were linked to false peaked 226-Hz tympanograms.</p><p><strong>Conclusions: </strong>The comparison of myringotomy findings and 226- and 1000-Hz tympanometry confirms the superiority of high-frequency tympanometry in infants younger than 12 months. Although this study identified some vague predictors of potentially false peaked 226-Hz tympanograms, the assessment of the middle ear state by 226-Hz tympanometry remains unreliable in young infants.</p>","PeriodicalId":49241,"journal":{"name":"American Journal of Audiology","volume":" ","pages":"1246-1256"},"PeriodicalIF":1.4,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142478863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
