영문 초록

Exostosis of external auditory canal (EAC) is broad-based lamellated bony outgrowth, which is typically common in individuals who frequently participate in aquatic activities. It forms most commonly as a reaction to cold water exposure in surfers. Also, it also occurs in other aquatic sport players such as swimmers, divers, and kayakers. Not to be confused with external auditory canal osteomas, this disorder is more commonly bilateral and manifests as multiple formation. However, without those specific past history of cold water exposure, idiopathic EAC exostosis have seldom been reported. In this case report, we present a 50-year-old male without history of cold water exposure complaining bilateral ear fullness and progressive left hearing loss. The diagnosis was bilateral exostosis of EAC by physical examination, computed tomography, and audiometries. Under general anesthesia, canaloplasty and type I tympanoplasty via retroauricular approach was done to the left ear due to preoperative conductive hearing loss. There was no recurrence or complications during the following 12 months postoperatively. We report this case with a review of literature.
