Pectoralis major muscle flap with amnion in oral cavity reconstruction.
The pectoralis major myocutaneous flap provides an excellent method for reconstruction of oral cavity defects. This flap has been used since 1978. However, the flap is not without problems. The major problem that has been seen is necrosis of the cutaneous and subcutaneous aspects of the flap. However, in all such instances the muscular portion of the flap survived. This complication was found to occur more commonly in the elderly, diabetics, patients with peripheral vascular disease and patients with excessive adipose or breast tissue superimposed between the cutaneous and muscular components of the flap. In this study the technique of oral cavity reconstruction in the high risk patient group has been modified to avoid using the skin component of the pectoralis major myocutaneous flap. Instead, pectoralis major muscle covered with amnion is used for reconstructive purposes with rapid healing and with very satisfactory functional and cosmetic results.
