颌骨软骨瘤、骨软骨瘤11例

11 caese of Jaw Chondroma and Osteochondroma

目的提高对颌骨软骨瘤和骨软骨瘤的认识、方法收集1978～1998年在我科住院治疗的颌骨软骨瘤、骨软骨癌11例，进行临床分析。结果发生在上颌骨3例、下颌骨8例（髁状突5例、喙突3例）。临床主要表现为局部包块、下颌骨偏颌畸形、关节弹响和开口受限。诊断主要依靠X线和术后病理。结论手术是唯一治疗方法。因软骨瘤复发可恶变为软骨肉瘤;骨软骨瘤可恶变为纤维肉瘤，故必须重视扩大切除和术后追踪观察。

Objective In order to improve recognition to jaw chondroma and osteochondroma.Methods 11 patients with jaw chondroma and osteochondroma were collected in our hospital from 1978 to 1998, and were analysed clinically. Results The lesions were in maxillary bone in 3 cases. In mandibular bone in 8 cases. Main clinical manifestations were local tumor, mandibular hemiprognathism, arthrosnap and opening mouth limit. Diagnosis depends mainly on X-ray and postoperative patholgy. Conclusion Operaion is the only way of treatment. Becouse chondroma recurrence can transfer to chondrosarcoma. Osteochondroma can transfer to fibrosarcoma. Enlarging operative range and folow-up survery are important.
