Use of Composite Osteotemporoparietal Fascia Flap for Midface Reconstruction After En Bloc Resection of Squamous Cell Carcinoma Involving the Zygomaticomaxillary Complex

Abstract

Summary:The osteotemporoparietal fascia flap (OTPFF) has been used for bony defects, especially on the maxilla and orbital floor. However, there are limited reports about the reconstruction of the zygoma. We report the use of composite OTPFF for reconstruction of zygomaticomaxillary complex. The patient had undergone zygomaticomaxillary complex reconstruction with composite OTPFF because of the resection of recurrent postradiation tumor. Extratemporoparietal fascia was harvested and rotated to cover the medullary surface of the bone flap. Flap was successfully transferred with complete bone integration. There were no surgical complications and excellent cosmetic result. The patient is free of disease 12 months post surgery. The OTPFF seems to be a good option in zygomatic reconstruction, even in previously irradiated fields. Utilization of extratemporoparietal fascia to cover the medullary surface of the bone flap has potential to be an advantageous technique to minimize bone exposure and improve flap integration.
