title: [Syndromes 11. Treacher collins syndrome].
abstract: Treacher Collins syndrome is seen once in 10.000 births. Inheritance is autosomal dominant with variable expressivity. The most prominent symptoms are antimongoloid slant of the eyelids, hypo- or even aplasia of the zygomata, very hypoplastic mandible with receding chin, deformed ear lobes and conductive hearing loss. With two to three operations a considerable improvement can be achieved. The correction of the eyelids is often the most difficult problem.
