Objective Outcomes of maxillary reconstruction with temporalis calvarial flap were evaluated. Methods We reconstructed an orbital floor by using a temporalis calvarial flap for six patients with maxillary defects. Results After 12 months, the flaps were alive without noticeable inflammation. The oral and nasal cavities were separated well by the flaps, and the patients were able to take food orally and did not exhibit speech intelligibility problems. Conclusion Temporalis calvarial flap restored the contour and maxillary function; thus, this flap is recommended for the reconstruction of maxillary defects.
