Spindle cell variant of ameloblastic carcinoma: a case report and review of literature.

Ameloblastic carcinoma is a rare and malignant odontogenic tumor. Approximately, 100 cases of ameloblastic carcinomas have been reported in the literature, with fewer than 10 reported cases of an even more rare variant with spindle-cell differentiation. Although it is presumed that most ameloblastic carcinomas arise de novo, it also appears capable of proliferating as carcinoma ex ameloblastoma.

Anteriorly pedicled wide temporalis muscle flap with the minimum zygomatic osteotomy technique for post-discectomy temporomandibular joint arthroplasty.

An anteriorly pedicled temporalis muscle flap has been shown to be a suitable interpositional material for the treatment of ankylosis and post-discectomy arthroplasty. The passage of the wide flap beneath the zygomatic arch into the joint space can be difficult owing to its bulk, causing excessive trauma to the vascularized pedicle. We describe the use of minimum zygomatic osteotomy without fixation for the passage of an anteriorly pedicled wide temporalis muscle flap for post-discectomy arthroplasty.
