Tissue-Plug Modification of Pectoralis Major Myocutaneous Flap for Intractable Pharyngocutaneous Fistula Repair.

Objective: To evaluate the feasibility and effectiveness of a novel tissue-plug modification of the pectoralis major myocutaneous flap for repairing intractable pharyngocutaneous fistulas, especially in difficult-to-access defects.

Materials And Methods: The novel technique involved designing a tissue-plug modification of pectoralis major myocutaneous flap and suspension sutures. Cadaver studies were performed to refine the surgical method before clinical application.
