口腔颌面部晚期恶性肿瘤及某些良性肿瘤进行根治性手术时,往往需要广泛切除,从而造成大面积软组织以及骨组织的缺损,后遗功能障碍及外貌畸形。近年来,由于复合组织瓣——肌皮瓣及骨肌皮瓣的临床应用,不但提高了肿瘤的切除率,而且可获得较好功能和外形的恢复。本文就胸大肌肌皮瓣及骨肌皮瓣的临床应用作一初步报道。手术操作在胸肋部(一般设计在相当于第4～5肋表面)以美蓝划好所需肌皮瓣的大小与形状,先解剖与显露胸大肌外侧缘,在此肌膜边缘与深部组织分开;并用手指沿其表面,在胸小肌 Oral and maxillofacial malignant neoplasms and some benign tumors for radical surgery, often require extensive excision, resulting in large areas of soft tissue and bone defects, posterior functional disorders and appearance of deformity. In recent years, due to the clinical application of composite tissue flap - myocutaneous flap and osteomyocutaneous flap, it not only improves tumor resection rate, but also obtains better function and shape recovery. This article on the pectoralis major myocutaneous flap and the clinical application of bone flap made a preliminary report. Surgical operation in the thoracic ribs (usually designed to be equivalent to the first 4 ~ 5 rib surface) to draw the necessary blue flap size and shape of the myocutaneous flap, the anterior pectoralis major dissection and the outer edge of the first, at the edge of the sarcolemma and Deep tissue separate; and with your fingers along its surface, in the pectoralis minor muscle
