Multimodal treatment of XXXX of the jaw.

@entity1 @entity3478 @entity5 @entity809 @entity3538 @entity2103 @entity421 @entity158
@entity421 ( @entity421 ) account for 40 to 60% of primary @entity3478 . About 10% occur in the head and neck region, frequently in the mandibula or maxilla. We treated a 30-year-old @entity1 with 26-month history of right-sided facial @entity158 and @entity809 . Investigation showed high-grade OS of the right mandibular coronoid process, affecting the mandibular nerve, @entity3538 (ICA). True en bloc resection was performed after upfront adjuvant chemotherapy. The ICA was trap-ligated intradurally, whereafter the floor of the middle fossa, including the mandibular nerve and the glenoid fossa, was detached from the skull base in one piece. Subsequently, a hemimandibulectomy, total parotidectomy, ICA sacrifice, and removal of the pterygoid plates and muscles were performed, and the abovementioned structures were removed as a solitary specimen, including the @entity5 . A sural nerve graft was interposed between five major facial nerve branches to reanimate the face. The @entity1 had an uneventful recovery, is able to eat, and has a partial @entity2103 . He has no @entity5 recurrence 26 months after surgery. OS of the jaw should be treated with radical surgery as the primary modality.
