Otological Observations on the “Treacher Collins Syndrome”

The “Treacher-Collins syndrome”, of which the most common symptoms are deformities of the eyelids, ears and upper and lower jaws, is described. The etiology of the syndrome is discussed and a short review of previous medical opinion is given. Three cases are described, in order to illustrate the need for otological examination in cases in which an operation for improvement of hearing is possible. As the etiology is still unclear, a study of the causal factors, especially in embryonic development, is desirable.
