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 posteri-orly. 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.
