The case of a 17- year-old female patient with a destructive aneurysmal bone cyst of the right mandibular condyle is presented. Surgery revealed an eggshell thin, partly perforated remaining condylar cortex with extension of the lesion into the surrounding soft tissues. Condylar resection with curettage of the adjacent soft tissues and recurrence prophylaxis with intranasal calcitonin for 1 week could not prevent recurrence after 6 months. In a second operation the ascending mandibular ramus was partly resected and immediately reconstructed with a newly developed alloplastic condylar head add-on system. This time the lesion was intraoperatively completely surrounded by solid cortical bone.
本文报告了一例17岁女性患者，患有右侧下颌骨髁突的破坏性动脉瘤样骨囊肿。手术发现剩余的髁突皮质呈蛋壳样薄，部分穿孔，病变延伸至周围软组织。进行髁突切除术，刮除相邻软组织，并使用鼻内降钙素预防复发1周，但6个月后仍未能防止复发。在第二次手术中，部分切除下颌升支，并立即使用新开发的异体塑料髁突头附加系统进行重建。这次术中病变被坚实的皮质骨完全包围。
