Functional oromandibular reconstruction with the microvascular composite groin flap.

Ten patients were reconstructed with the microvascular osteocutaneous groin flap for oromandibular defects with the objective of improving function. The flap was based on the superficial and deep circumflex iliac vessels for optimal positioning of the bone and contouring of the skin. Patients with major glossectomies and arch resections had intelligible speech and were able to eat a soft diet without aspirating. Cineradiographic studies to evaluate swallowing in selected patients showed that the shape of the intraoral flap and the location of the bone graft played an important role in swallowing and prevention of aspiration.
