Head and neck reconstruction with the deep inferior epigastric perforator flap: a report of two cases.

Rectus abdominis musculocutaneous (RAMC) free flaps are preferred for head and neck reconstruction because of the abundant blood supply to the rectus abdominis musculocutaneous. In contrast, the indications for deep inferior epigastric perforator (DIEP) free flaps in head and neck reconstruction are limited. In this report, two cases of oral cavity reconstruction with DIEP free flaps are described. In both cases, the defect was reconstructed with a DIEP free flap because it could avoid functional damage to the donor site. Successful reconstruction with a two skin-island method was performed in both patients. Furthermore, donor site morbidity was minimal in both patients. When a DIEP free flap is used for head and neck reconstruction, elimination of dead space is the most difficult problem, because a DIEP free flap does not contain well-vascularized muscle tissue. We compensate for this disadvantage with a flap designed to include a de-epithelialized skin flap. Although this technique is not always the first choice for head and neck reconstruction, it is suitable for patients who wish to avoid donor site morbidity.
