摘要

骨性纖維瘤屬於纖維骨性病症的一種，爲良性、生長緩慢之腫瘤，病理上可見正常之骨質被膠原纖維、纖維母細胞取代。常見於10歲至40歲，女性略多，大多數爲單一病灶，好發於頭骨，其中又以下頜骨最爲常見，其餘部位則少見。治療傳統上以手術刮除爲主。本院經歷1名16歲男性，主訴左側斷續耳漏、耳痛、伴左耳耳鳴及聽障達1年多，理學檢查可見左側外耳道充滿肉芽組織，純音聽力檢查爲左側傳導性聽力隙礙，高解析度電腦斷層攝影顯示左側顯骨疑似骨纖維結構不良，左側外耳道口狹窄及耳道充滿軟組織。經左側耳道成型術切除部分骨性病變、去除膽脂瘤及肉芽組織。病理診斷爲骨性纖維瘤併外耳道膽脂瘤。手術後7個月追蹤，左側耳道通暢，聽力恢復正常。

Ossifying fibroms is a benign and slow-growing fibro-osseous lesion in which the normal bone material is replaced by collagen fiber and surrounded by osteoblasts. The prevalent age is of 10 and 40 years old, with female preponderance. The typical growth characteristics is monostotic and mostly occurring in the skull bone, especially in the mandible. Surgical excision remains the first choice of treatment. We reported a 16-year-old male who suffered from left otorrhea, otalgia, tinnitus, and progressive hearing impairment for more than one year. The physical examinations revealed left external ear canal (EAC) filled with granulation. The pure tone audiometry indicated left side conductive hearing loss. High resolution computed tomography showed a left temporal bone mass suspected to be fibrous dysplasia, and left EAC stenosis filled with soft tissue. He received left canalplasty which removed partial bony lesion and the soft tissue. The pathology report confirmed the diagnosis of left temporal ossifying fibroma and EAC cholesteatoma. After 7-month of follow up, the left EAC stays patent and the hearing impairment is ameliorated.
