Oral cavity reconstruction using pectoralis major muscle and amnion.

The pectoralis major myocutaneous flap has become the mainstay of major oral cavity reconstruction. The flap provides excellent soft-tissue bulk and cavity or surface lining for major defects. There is a high rate of primary take. However, the flap has some deficiencies. A group of patients were identified that are likely to have less than ideal results with the pectoralis major myocutaneous flap technique. In these cases, the flap has been modified and amnion has been added. Initial results indicate enhancement of reconstruction with the modified technique.
