髁突肥大继发牙颌面畸形的诊断与治疗

Treatment of dentofacial deformities secondary to condylar hyperplasia

髁突肥大继发牙颌面畸形,是由于髁突非肿瘤性过度增生而导致面部不对称畸形、咬合紊乱、颞下颌关节功能障碍等症状的一种疾病。该病病因仍不明确,目前以正颌外科、关节外科、颌骨轮廓整形术以及术前、术后正畸治疗作为主要治疗方式,根据髁突增生的活跃程度、颌骨畸形的严重程度以及患者意愿,制定个性化治疗方案以期矫治颌骨畸形、改善咬合关系、重建良好的关节功能。本文将从髁突肥大继发牙颌面畸形的病因、临床表现、影像学特点、治疗目标及手术方式选择结合笔者经验对该病的诊治作一系统论述。

Dentofacial deformities secondary to condylar hyperplasiais a kind of disease presenting facial asymmetry,malocclusion,temporomandibular joint dysfunction,and other symptoms caused by non-neoplastic hyperplasia of the condyle.The etiology is still unknown,and currently,pre-and post-operative orthodontics accompanied by orthognathic surgery,temporomandibular joint surgery and jawbone contouring surgery are the main treatment methods.A personalized treatment plan was developed,considering the active degree of condyle hyperplasia,the severity of the jaw deformity,and the patient’s will,to correct deformity,obtain ideal occlusal relationship,and regain good temporomandibular joint function.Combined with the author’s clinical experience,the etiology,clinical and imageological features,treatment aims,and surgical methods of condylar hyperplasia and secondary dentofacial deformities were discussed in this paper.
