XXXX of pterygoid fossa. Resection for cure utilizing an innervated facial flap and craniofacial reconstruction.

@entity1 @entity980 @entity5 @entity41
Tumors of the pterygoid fossa are often regarded as unresectable because of their anatomic inaccessibility. The rapidly developing techniques of craniofacial surgery have advanced sufficiently to now allow safe ablative surgery in this area and yet preserve the functional status and cosmetic appearance of the @entity1 . A technique utilizing a bicoronal incision that is extended to the angle of the mandible on the involved side is described. This allows wide exposure of the bony structures at the lateral base of the skull while maintaining the integrity of the facial nerve within the cutaneous flap. Temporary removal of the zygomatic arch achieves direct access to and visualization of the contents of the temporal and pterygoid fossae. Skull, mandibular, and maxillary bone adjacent to @entity5 can easily and safely be resected to obtain complete @entity5 -free margins. Craniectomy bone is harvested and split into inner and outer tables to reconstruct the bony defects. This approach was successfully utilized in a 5-year-old @entity1 with a Group III @entity980 with @entity41 following combined chemo- and radiotherapy. He remains @entity5 -free at 15 months, postoperation. The technique can be adapted for a variety of mass lesions located at the anterior base of the skull, both intra- and extracranially. Morbidity and mortality should be minimal with an experienced craniofacial team.
