Abstract

Background: Ear auditory exostoses (EAE) or surfer’s ear is a slow benign bony growth within the external auditory canal (EAC). The exact etiology of EAE remains unclear but it is commonly associated with chronic exposure to cold water or wind. The technique of surgery can be transcanal, endaural, or postauricular approach, based on the surgeon's experience. To our knowledge, this is the first documented report of a patient with recurrent EAE without cold water exposure. The purpose of this study is to present a rare case report about a woman with unilateral EAE without cold water exposure with transcanal osteotome surgical approach.

Case presentation: A 29-years-old woman was referred to the Ear, Nose, and Throat Department, West Nusa Tenggara General Hospital, Mataram, Indonesia with left ear fullness since one week ago. The patient was told that she had a lump within the ear canal since 2013 but she had no symptoms. There was no history of recurrent ear infection or participating in water activities. Otoscopy of the left ear revealed a lump rising from EAC that covers 90% of EAC. We could not visualize the left tympanic membrane. The CT scan of her temporal bone demonstrated a hard density mass in the left EAC. The patient was done surgically with a transcanal approach. Indication for this patient was the occlusion of more than 80% of EAC. Transcanal with osteotome was chosen because of its less complication than others.

Conclusion: It is unusual that our patient developed EAE without the usual precipitating factor. The surgery was done with a transcanal approach with an osteotome to prevent complications postoperative. Future experimental studies should be performed.
