Abstract
The complexity of cranial base surgery is a reflection of skull base anatomy as well as technical demands for maximum visualization, control of essential structures, adequate tumor resection and/or reconstruction. Facial translocation has been developed as a new approach to cranial base. It consists of extensive modular facial disassembly which includes displacement of composite facial soft tissue flap and craniofacial skeleton. It creates surgical field with epicenter in nasopharynx and infratemporal fossa allowing easy expansion into sphenoid bone and cranial fossae as well as craniovertebral junction. Reconstruction is functional and esthetic. Versatility of this approach permits expansion into neighboring craniofacial regions. During a 14-month period (11/88-12/89), this facial translocation approach to cranial base was utilized in 20 patients. The approach provided excellent visualization of the involved cranial base permitting oncological as well as reconstructive procedures. All patients healed primarily. Two patients were reoperated on at 4 and 6 months postoperatively; one for a bone graft infection and the other for tumor recurrence. The facial translocation approach offers favorable exposure of the critical zones of cranial base resulting in increased surgical safety and benefit of cranial base surgery.
