✦ Synopsis
Extensive midfacial defects after ablative surgery constitutes a challenging problem for reconstructive surgeons. Particularly for types IV and V midfacial defects, provision of missing bony support and obliteration of the maxillary cavity defects require microsurgical free tissue transfers. In the last three years, four patients have undergone total maxillectomy for midfacial tumours and the postmaxillectomy defects were three-dimensionally repaired with free rectus abdominis muscle flap and skin graft or myocutaneous flaps. Obliteration of maxillary cavity defects and orbital support were achieved with this type of free flap. The least follow-up period of the patients is one year and slight ectropion, later corrected, was seen in two patients. In this study, the free rectus abdominis myocutaneous (RAM) flap, with its long vascular pedicle and availability of various skin paddle designs and muscle bulk, is presented in treatment of extensive midfacial defects. In spite of initial overcorrection of contour, the denervated rectus abdominis muscle gradually atrophies, resulting in loss of contour. The muscle bulk fills the cavity defect, but, in order to achieve good facial contour, it is necessary to support the bony skeleton with some material.
