To assess the application of computer assisted surgical navigation in condylectomy via intraoral approach and its clinical results.
Eight patients aged from 16 to 56 were treated by condylectomy via intraoral approach under computer assisted surgical navigation. There were 6 female and 2 male. The lesions were condyle osteoma in 3 patients, hemimandibular hyperplasia and condylar hyperplasia in 5 patients. Most patients had concomitant LeFortIosteotomy (6 cases), bilateral sagittal split ramus osteotomy (BSSRO) (5 cases),contralateral sagittal split ramus osteotomy (SSRO) (1 cases), genioplasty (4 cases) and mandible contouring (6 cases) to recover the facial symmetry.
All patients had good occlusion, oral function and facial symmetry after the operation. The average mouth opening was 38 mm before operation, and 41 mm one month after operation. The temporomandibular joint(TMJ) dysfunction syndrome alleviated or disappeared. The follow-up period was 3-12 months, and results were stable.
Computer assisted surgical navigation can precisely accomplish the condylectomy via intraoral approach.It causes less trauma to the patient than traditional condylectomy, and can better preserve the TMJ structure and function.
评估计算机辅助手术导航在经口入路髁突切除术中的应用及其临床效果。
8例年龄在16至56岁之间的患者在计算机辅助手术导航下接受经口入路髁突切除术。其中女性6例，男性2例。病变包括3例髁突骨瘤，5例半侧下颌骨增生和髁突增生。大多数患者同时进行了LeFortI截骨术（6例）、双侧矢状劈开下颌支截骨术（BSSRO）（5例）、对侧矢状劈开下颌支截骨术（SSRO）（1例）、颏成形术（4例）和下颌骨轮廓整形术（6例）以恢复面部对称性。
所有患者术后咬合、口腔功能和面部对称性均良好。术前平均开口度为38mm，术后1个月为41mm。颞下颌关节（TMJ）功能紊乱综合征减轻或消失。随访3至12个月，结果稳定。
计算机辅助手术导航能够精确完成经口入路髁突切除术。与传统髁突切除术相比，对患者造成的创伤更小，并且能够更好地保留颞下颌关节的结构和功能。
