Treacher Collins syndrome (TCS), mandibulofacial dysostosis, or Franceschetti-Zwahlen-Klein syndrome, is a rare genetic disorder characterised by dysgenesis of the hard and soft tissues of the first and second branchial arches. Early operations focus on maintaining the airway, protecting the eyes, and supporting auditory neurological development. Later operations include staged reconstruction of the mouth, face, and external ear. Bimaxillary surgery can improve the maxillomandibular facial projection, but correction of malar, orbital rim, and temporal defects may be more difficult. We present a clinical review of the syndrome with a chronological approach to the operations.
