title: Results of the Tessier integral procedure for correction of Treacher Collins syndrome.
abstract: A new procedure is proposed for correction of the malformations of severe cases of Treacher Collins syndrome in the areas of the maxilla, mandible, and orbit. The operation essentially consists of a rotation of the midfacial segment around a transverse axis at the frontonasal angle. The midface is rotated forward anteriorly and downward posteriorly. It is stabilized by cranial grafts impinged into the temporal bone and the maxilla. The mandible is lengthened either by V shape osteotomy or bone grafting of the ramus. The mandible is fixed in an overjet class III dental occlusion. A posterior bite wafer is maintained for 2 months. The construction of the orbital cavity is completed with cranial bone grafts. The Tessier integral procedure for Treacher Collins syndrome has been done in one stage in six patients and in two stages in five patients. Sufficient data were available for analysis of only four patients.
