中文摘要：

骨软骨瘤属于良性肿瘤，髁突是颌面部骨软骨瘤易受累的部位。髁突骨软骨瘤主要表现为关节区肿块、关节功能异常，常继发不对称性牙颌面畸形。手术仍是治疗的主要方法。手术应彻底切除肿瘤、重建关节功能、纠正错耠畸形以获得稳定良好的口颌系统功能。同时应矫正其异常和畸形容貌，以达到功能与形态俱佳的效果，常需以多种手术结合为主的综合治疗方案。本文从髁突骨软骨瘤的病因、临床特点、影像学特点、治疗目标和手术方式等方面对该病的诊治作一系统论述。

英文摘要：

Surgical treatment of condylar osteochondroma combined with secondary dentofacial deformities is a significant clinical challenge. Diagnosis and treatment protocol of condylar osteochondroma patients who also have secondary dentofacial deformities are discussed according to the features of tumor and dentofacial deformities. The condylar osteochondroma and secondary dentofacial deformities were treated through one or several methods of tumor resection, condylar reconstruction, correction of skeletal deformities, and treatment of malocclusion. Temporomandibular joint function, occlusion, and facial appearance were evaluated after operation by radiographic examination and follow- up. Surgical management of condylar osteochondroma with secondary dentofacial deformities requires careful patient selection, treatment planning, and precise execution.
