ABSTRACT
BACKGROUND AND OBJECTIVES@#External auditory canal osteoma is an uncommon benign lesion and represents as unilateral solitary pedunculated mass. The aim of this study is to evaluate the clinical symptoms of osteoma and its treatment outcomes over a 10-year period in a tertiary hospital.SUBJECTS AND METHOD:
Eight patients underwent operation to remove an external auditory canal osteoma at Chungbuk National University Hospital from 2008 to 2017. The medical records were retrospectively reviewed with regard to clinical characteristics, size and location of osteoma, method of surgery and treatment outcomes.@*RESULTS@#The average age of patients was 41.8 years with the male predominance of 62. All of the lesions in the osteoma were unilateral and solitary (average size 5.0 mm). All of the eight cases were pedunculated in four cases, the stalks of the osteoma were found on the tympanomastoid suture line and in three cases, it was found on the tympanosquamous suture line. Four patients were asymptomatic, where the lesions were found incidentally during unrelated evaluations. No patients were found with conductive hearing loss in the pure tone audiometry. Transcanal and endaural approach were used in five and three cases, respectively. Most of the cases were removed by curettage only, except for the two who needed additional drilling. The average surgery time was 15.6 minutes. There was no postoperative complication or recurrence.@*CONCLUSION@#The external auditory canal osteoma was mostly unilateral and solitary. The removal of osteoma in the early stage was relatively easy with no recurrence or complication.
