OBJECTIVE
To summarize the experience of diagnosis and treatment on osteoma in the external auditory canal.
METHOD
Retrospective study were undertaken in 26 patients with osteoma in the external auditory canal operated in author's unit.
RESULT
Osteomas were removed through interauricular approach in all patients and confirmed by histopathological examination. The hearing of 22 patients with conductive hearing loss became normal after operation. The air conduction hearing threshold in 2 patients with mixed hearing loss improved average 15 dB and 20 dB respectively after operation. The follow up was more than 1 year, and no recurrence or complications had occurred.
CONCLUSION
Osteoma in the external auditory canal is an uncommon benign lesion. The method of choice in diagnosis is temporal bone CT scan. Osteoma must be distinguished from exostosis in the external auditory canal. Osteoma is confirmed by pathological diagnosis and surgery is the only method for treatment.
目的
总结外耳道骨瘤的诊断与治疗经验。
方法
对作者所在单位收治的26例外耳道骨瘤患者的手术资料进行回顾性研究。
结果
所有患者均经耳内入路切除骨瘤，术后病理检查确诊。22例传导性听力损失患者术后听力恢复正常。2例混合性听力损失患者术后气导听力阈值分别平均提高了15dB和20dB。随访1年以上，无复发及并发症发生。
结论
外耳道骨瘤是一种少见的良性病变。颞骨CT扫描是诊断的首选方法。外耳道骨瘤必须与外耳道骨疣相鉴别。病理诊断可确诊，手术是唯一的治疗方法。
