口腔颌面部恶性肿瘤根治术时往往造成软组织大面积缺损,而导致颌面部明显畸形与器官功能障碍。以往因恶性肿瘤作广泛切除得不到立即整复,使手术治疗受到限制。近年来,由于肌皮辦的问世,特别是胸大肌肌皮辦的临床应用,给口腔颌面外科开创了广阅的前景。它不仅提高了恶性肿瘤的切除率,扩大整复范围,而且缩短了疗程,提高了外形及功能整复的效果。有的学者亦指出:此瓣蒂部较为臃肿易扭转而影响血运。作者根据这一缺点对蒂部进行了改进,取得了较为满意的效果。我科自1982年至1984年收治两例颌面部恶性肿瘤和一例颌面部恶性肿瘤因行放射治
Oral and maxillofacial malignancies often result in large-scale soft tissue defects, resulting in significant deformity of the maxillofacial region and organ dysfunction. In the past due to extensive removal of malignant tumors can not be immediately rectified, surgical treatment is limited. In recent years, due to the advent of musculoskeletal office, in particular the clinical application of pectoralis major muscle skin, opened up a broad prospect for oral and maxillofacial surgery. It not only improves the resection rate of malignant tumors, expand the scope of rehabilitate, but also shorten the course of treatment, improve the appearance and function of the effect of the whole complex.
