Delayed post-neonatal intensive care unit hearing disturbance.

Ten children, who developed hearing disturbance after discharge from the neonatal intensive care unit (NICU), are reported. All were born at full term, between November 1988 and November 1992, weighed at least 2500 g and had normal auditory brainstem response (ABR) at discharge from the NICU. All ten underwent thorough evaluation to determine the cause of the subsequent hearing loss.

[Hearing loss following discharge from the NICU].

We experienced 10 pediatric cases born between November of 1988 and November of 1992, whose ABR were normal at the time of discharge from the NICU, who subsequently developed hearing impairment. These children underwent thorough evaluations and the causes of their hearing loss are discussed herein. All 10 were born at full term, birth weights ranged from 2500g to 3826g, and all had severe cardiovascular and/or pulmonary disorders.

Choanal atresia and congenital pharyngeal stenosis.

From 1980 to 1992, 8 patients with choanal atresia were treated in our facility. The female to male ratio was 5:3. One patient, a girl, had unilateral osseous obstruction with membranous closure of the opposite naris while the other 7 had bilateral osseous obstruction.
