ABSTRACT
BACKGROUND AND OBJECTIVES:
Osteoma of the external auditory canal is an uncommon benign lesion and represents as a unilateral pedunculated mass in the outer half of the bony canal. The aim of this study is to evaluate the clinical, histopathological characteristics of osteoma and its treatment outcomes. MATERIAL ANDMETHODS:
We have operated 9 patients who visited Chungnam National Universitv Hospital in the past 10 years with the complaints of osteoma arising from the external auditory canal. The medical records were retrospectively reviewed with regard to clinical characteristics, surgical findings, histopathological features and treatment outcomes.RESULTS:
One patient showed regrowth of the tumor after surgery and CT scans demonstrated a hidden lobe embedded in soft tissue of the bony-cartilaginous junction. Five patients have had no connection with regard to tympanosquamous or tympanomastoid suture line, which had been known as the predilection site.CONCLUSION:
Osteoma of the external auditory canal is a distinct benign tumor which can be removed easily. A precise preoperative evaluation of the extent of the tumor and a complete surgical removal under adequate exposure is the best way to ensure no recurrence or complication.
