Abstract

Patients with Treacher Collins Syndrome have severe middle ear malformations. We have studied HRCT of seventeen patients with Treacher Collins Syndrome by using Jahrsdoerfer's grading system. Four patients underwent canalplasty. The appearance of the auricle (which we evaluated by using Marx's grading system) was correlated with the development of the middle ear in patients with Treacher Collins Syndrome. The four cases who underwent canalplasty were using a canal type hearing aid.
