Osteoma is a rare slow-growing benign neoplasm which is often asymptomatic and composed of mature bone. Only 21 cases were previously reported in the mandibular condyle.
A 60 year old male presented with gross asymmetry of the lower jaw and reduced function. He mentioned that he was involved in an accident to the head about 16 years ago. Upon examination, it was noticed that the chin deviated to the left with some discomfort during function. Computed tomography revealed a radiopaque mass medial to the left condylar pole. The lesion was gradually increasing in size and in close proximity to the middle cranial fossa. A condylectomy was performed using a pre-auricular approach. A diagnosis of osteoma was confirmed histopathologically. The defect was reconstructed with stock TMJ prostheses.
Osteomas affecting the condyle have significant functional implications and should be considered when deviation of the mandible is present.
骨瘤是一种罕见的缓慢生长的良性肿瘤，通常无症状，由成熟骨组成。以前仅在下颌骨髁突中报告过 21 例。
一位 60 岁男性出现下颌骨明显不对称和功能减退。他提到大约 16 年前头部曾受过一次外伤。检查时发现下巴向左偏斜，功能时有些不适。计算机断层扫描显示左侧髁突极内侧有一个不透射线的肿块。病变逐渐增大，并与中颅窝相邻。采用耳前入路行髁突切除术。组织病理学证实为骨瘤。使用 TMJ 假体重建缺损。
影响髁突的骨瘤具有重要的功能意义，当下颌骨偏斜时应考虑骨瘤。
