Evaluation of craniofacial surgery in the treatment of facial deformities.

Surgical access to the cranial, orbital, and facial areas, as developed by Tessier, has produced not only definitive repair of previously uncorrectable congenital deformities such as orbital hypertelorism and facial stenosis (e.g., Crouzon's, Apert's syndromes) but also has improved markedly the treatment of traumatic and neoplastic defects. The surgical approach allows complete dissection of facial soft tisses including the orbits from the underlying bones followed by corrective osteotomies and fixation. Mobilization of the frontal lobes through a frontal bone flap exposure may be required. The ramifications of this latest intrusion by surgeons into a previously inviolate anatomic area have involved neurosurgeons, ophthalmologists, anesthesiologists, and dental and psycho-social disciplines. The disciplines of genetics and embryology are being influenced by this new field of surgery, much as the study of immunology was influenced by transplantation surgery two decades ago. This report analyzes a 10 year experience with over 100 patients with emphasis on patient selection by disease, age, intellectual status, morbidity, complications, and the psycho-social reactions of patient and family. Procedures initially planned to correct dental and aesthetic defects are proving beneficial for other functions including hearing, taste and smell, articulation and tongue movement, respiratory function, vision, and possibly bone growth. The development of self image, a normal process always in operation, is also strikingly altered. These operations may last as long as 14 to 16 hours. We have had no deaths or postoperative blindness. One postoperative cerebrospinal fluid leak was successfully repaired. Three partial losses of bone grafts and four instances of late cellulitis have occurred. Prevention of infection seems related to avoidance of dead spaces and primary closure of all mucosal, dural, conjunctival and skin surfaces.
