Cornelia de Lange Syndrome: Otolaryngologic Manifestations

Cornelia de Lange syndrome (CDLS) is characterized by multiple congenital malformations and mental retardation. New studies have documented otolaryngologic abnormalities. We examined 45 patients with CDLS. Virtually all had hearing loss, and most had impaired language development. Other otolaryngologic abnormalities, including external auditory canal stenosis and cleft palate, were also common. Because of the high incidence of otolaryngologic abnormalities, and the need for early intervention, it is important for otolaryngologists to recognize CDLS manifestations in the head and neck.
