Pedicled temporoparietal galeal myofascial flap for orbital and cheek lining following radical maxillectomy.
Radical maxillectomy is indicated for stage III and IV antroethmoidal carcinoma. In those cases where the anterior bony wall of maxillary antrum or the anterior facial soft tissue is involved or a previous Caldwell-Luc antrostomy was performed, a generous amount of cheek soft tissue has to be resected with the surgical specimen in order to achieve tumour-free margins. In such cases survival of the cheek flap is in jeopardy. Following orbital exenteration the resultant defect requires covering to promote healing and to protect the underlying bone. Traditionally, a skin graft has been used to line the orbital defect and the cheek flap. The pedicled temporoparietal galeal myofascial flap offers well-vascularized, reliable, supple and plentiful tissue which can be used to line both the orbit and the cheek, thus covering both sites with one flap. Such a case is presented and the surgical anatomy and technique are described.
