Mastoid fistula is a rare condition, its causes include chronic suppurative otitis media and repeated ear surgeries. Management is challenging, simple closure typically leads to recurrence due to surrounding necrotic skin edges. Several surgical techniques have been described. In this paper, we present a case of a 60 year old lady who presented with chronic right ear discharge post radical mastoidectomy due to acquired cholesteatoma. At presentation, there was a mastoid opening found over her auricular sulcus, endoscopic examination showed a well epithelized mastoid cavity with mucopurulent discharge, CT of temporal bone correlated with physical findings. The fistula was surgically closed with a three-layer pedicled flap and the fistula was fully healed at the 1-month follow up.
乳突瘘是一种罕见的病症，其病因包括慢性化脓性中耳炎和反复的耳部手术。治疗具有挑战性，单纯缝合通常会因周围坏死的皮肤边缘而导致复发。已经描述了几种手术技术。在本文中，我们报告了一例60岁女性患者，她因后天性胆脂瘤行根治性乳突切除术后出现右耳慢性流脓。就诊时，在她的耳廓沟处发现一个乳突开口，内镜检查显示乳突腔上皮化良好，有黏液脓性分泌物，颞骨CT与体格检查结果相符。通过三层带蒂皮瓣手术封闭瘘管，术后1个月随访时瘘管完全愈合。
