The pectoralis major myocutaneous (PMMC) flap is commonly used for head and neck reconstruction especially in impoverished nations. PMMC is a sturdy pedicled flap with relatively fewer complications, the learning curve is short and no specialized training in microvascular surgery is needed in order to use this flap. In a defect that requires a large skin and mucosal lining the authors routinely use either a bi-paddle PMMC or a combination of PMMC (for the mucosal lining) and a delto-pectoral flap (for the skin defect). It is indisputable that free tissue transfer is a better way of reconstruction for the majority of most such defects. Unfortunately, not all patients can be offered this form of reconstruction due to the cost, time, expertise and infrastructural constraints in high volume centres such as ours. Bi-paddling of PMMC is hazardous in obese males and most female patients. In such patients the skin defect is reconstructed usually by the delto-pectoral (DP) flap but this, for obvious reasons, is less welcomed by the patients. The authors suggest a technique wherein mucosal lining is created by the myofascial lining (inner surface) of the flap and the skin defect is reconstructed by the skin paddle of the single paddle PMMC. It should be considered wherever a DP flap is unacceptable, or bi-paddling or free tissue transfer is not possible.
胸大肌肌皮瓣(PMMC)常用于头颈部重建,尤其是在贫困国家。PMMC是一种坚固的带蒂皮瓣,并发症相对较少,学习曲线短,使用该皮瓣无需微血管手术的专门培训。对于需要大面积皮肤和黏膜衬里的缺损,作者通常常规使用双叶PMMC或PMMC(用于黏膜衬里)与三角胸肌皮瓣(用于皮肤缺损)的组合。无可争议的是,对于大多数此类缺损,游离组织移植是更好的重建方式。不幸的是,由于我们这样的高容量中心存在成本、时间、专业知识和基础设施限制,并非所有患者都能接受这种重建形式。PMMC双叶化对肥胖男性和大多数女性患者有风险。在此类患者中,皮肤缺损通常用三角胸肌皮瓣(DP)重建,但显然,患者对此不太欢迎。作者提出一种技术,即通过皮瓣的肌筋膜衬里(内表面)形成黏膜衬里,皮肤缺损用单叶PMMC的皮瓣重建。只要DP皮瓣不可接受,或无法进行双叶化或游离组织移植,就应考虑采用该技术。
