This report illustrates the importance of expeditiously evaluating for retrocochlear pathology even in young active duty service members with asymmetric or sudden hearing loss. A 36-year-old male presented with right-sided sudden hearing loss and dizziness. Audiometry revealed profound mid-to-high-frequency sensorineural hearing loss in the right ear. A 10-day course of oral steroid therapy and two intratympanic steroid injections were unsuccessful in restoring hearing. MRI revealed a 4.2 cm contrast-enhancing cerebellopontine angle tumor, consistent with a vestibular schwannoma (VS). Microsurgical resection utilizing a retrosigmoid craniotomy approach was performed with near-total resection of the tumor and preservation of the facial nerve but not the cochlear nerve. Despite preservation of the facial nerve, progression of post-operative facial weakness required gold weight placement to prevent exposure keratopathy. The patient had recovered partial function in all facial nerve branches at last follow-up. In light of the rising global incidence of VS, any asymmetric or sudden hearing loss in military service members should be evaluated with audiometry and referral to otolaryngology for workup of retrocochlear pathology.<\/jats:p>","DOI":"10.1093\/milmed\/usab040","type":"journal-article","created":{"date-parts":[[2021,2,21]],"date-time":"2021-02-21T06:56:15Z","timestamp":1613890575000},"page":"637-642","source":"Crossref","is-referenced-by-count":4,"title":["Sudden and Asymmetric Hearing Loss Among Active Duty Service Members: Underscoring the Importance of Active Screening"],"prefix":"10.1093","volume":"186","author":[{"given":"John M","family":"Sommerfeldt","sequence":"first","affiliation":[{"name":"Walter Reed National Military Medical Center, Bethesda, MD 20889, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John P","family":"Marinelli","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, San Antonio Uniformed Services Health Education Consortium, San Antonio, TX 78234, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Samuel A","family":"Spear","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, San Antonio Uniformed Services Health Education Consortium, San Antonio, TX 78234, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2021,5,3]]},"reference":[{"issue":"10053","key":"2021050314251832500_R1","doi-asserted-by":"crossref","first-page":"1545","DOI":"10.1016\/S0140-6736(16)31678-6","article-title":"Global, regional, and national incidence, prevalence, and years lived with disability for 310 diseases and injuries, 1990-2015: a systematic analysis for the Global Burden of Disease Study 2015","volume":"388","author":"GBD: 2015 Disease and Injury Incidence and Prevalence Collaborators","year":"2016","journal-title":"Lancet"},{"issue":"3","key":"2021050314251832500_R2","doi-asserted-by":"crossref","first-page":"351","DOI":"10.1007\/s00420-015-1083-5","article-title":"Occupational noise exposure and hearing: a systematic review","volume":"89","author":"Lie","year":"2016","journal-title":"Int Arch Occup Environ Health"},{"key":"2021050314251832500_R3","volume-title":"Annual benefits report, fiscal year","author":"Department of Veterans Affairs","year":"2019"},{"issue":"28","key":"2021050314251832500_R4","first-page":"955","article-title":"Severe hearing impairment among military veterans\u2014United States, 2010","volume":"60","author":"Groenewold","year":"2011","journal-title":"MMWR Morb Mortal Wkly Rep"},{"issue":"1_suppl","key":"2021050314251832500_R5","doi-asserted-by":"crossref","first-page":"S1","DOI":"10.1177\/0194599819859885","article-title":"Clinical practice guideline: sudden hearing loss (update)","volume":"161","author":"Chandrasekhar","year":"2019","journal-title":"Otolaryngol Head Neck Surg"},{"key":"2021050314251832500_R6","article-title":"Cochlear implantation in the active duty military population: a survey assessing military readiness and satisfaction","author":"Sommerfeldt","year":"2020","journal-title":"Otol Neurotol"},{"issue":"4","key":"2021050314251832500_R7","doi-asserted-by":"crossref","first-page":"695","DOI":"10.1177\/0194599818756300","article-title":"Asymmetric hearing loss prompting mri referral in a military population: redefining audiometric criteria","volume":"158","author":"Tolisano","year":"2018","journal-title":"Otolaryngol Head Neck Surg"},{"issue":"1","key":"2021050314251832500_R8","doi-asserted-by":"crossref","first-page":"95","DOI":"10.5152\/iao.2018.5364","article-title":"EAONO position statement on vestibular schwannoma: imaging assessment.
