• The pectoralis myocutaneous flap has been widely used for reconstruction of oral cavity and pharyngeal defects. However, it has several disadvantages, such as chest distortion, hair growth at the reconstructed site, and excessive bulk, all of which can be avoided by the use of the pectoralis myofascial flap. Oral cavities and pharyngeal defects, ranging in size from 4 to 9 cm in largest dimension, in 26 patients were reconstructed with the pectoralis myofascial flap. All but three defects were successfully reconstructed. The surface of the flap was covered by squamous epithelium in 1 month. The flap remained healthy during and after radiotherapy. The pectoralis myofascial flap is ideal for softtissue coverage of small- to medium-size oral cavity and pharyngeal defects. Its major advantages over the pectoralis myocutaneous flap are decreased bulk and improved cosmesis.
