带蒂超长下斜方肌肌皮瓣修复头颈部组织缺损

Application of extralong inferior trapezius musculocutaneous pedicle flap to the restoration of defect in head and neck tissue

目的报道诺蒂超长下斜万肌肌皮瓣修复头颈部组织缺损。方法在对斜方肌及其血供进行显微外科解剖学研究的基础上利用颈横动脉浅降支为蒂设计超长下斜方肌肌皮瓣，其远端可达肩胛下角下17cm处，单侧皮瓣最大面积为36cm×13cm，双侧皮瓣总面积可超过700cm2，皮瓣转移可覆盖颅项、颌面及颈部缺损。结果临床应用修复头颈部组织缺损8例，其中2例采用双侧肌皮瓣转移，10块皮瓣均完全成活。结论超长下科方肌肌皮瓣是修复头颈部组织缺损的较好方法。

Objective To study the application of extralong inferior trapezius musculocutaneous pedicle flap to the restoration of the defect in head and neck tissue. Methods On basis of microsurgical anatomy of the trapezius muscle,extralong musculocutaneous flap obtained from the lower portion of the trapezius pedicle with superficial descending branch of the transverse cervial artery(TCA) was designed with a maximum size of up to 36cm × 13cm. The size of the bilatera1 flaps were 7OOcm2. The distal end of the flap was along the hairline of forehead. Results This restoration technique has been used in 8 cases and all the flaps survived completely. Conclusion The extralong trapezius musculo cutaneous pedicle flap is an appropriate method for the restoration of the head and neck tissue defects.
