Hemimaxillectomy for Desmoplastic Ameloblastoma With Immediate Temporalis Flap Reconstruction

Abstract

Ameloblastoma is one of the most common odontogenic tumors encountered, occurring more frequently than all other tumors combined, if one excludes the keratocystic odontogenic tumor. These tumors can cause severe expansion of the cortical bones and gross anatomic deformities. They can affect the dentition, causing tooth mobility and displacement. Fortunately, morbidity can be minimized with recognition on routine radiographic examination. The tissue may be unilocular or multilocular and has been described as having a "soap-bubble" appearance. Nevertheless, its radiographic appearance is insufficient to make a definitive diagnosis, because other tumors have similar appearance. Although the anatomic distribution and progression of ameloblastoma remain fairly consistent, alternative manifestations follow an atypical clinical course. One such variant is the desmoplastic ameloblastoma. We present a case of maxillary desmoplastic ameloblastoma treated with hemimaxillectomy and immediate reconstruction with temporalis flap that was recurrence-free at 36 months.
