Hearing and speech assessment of cleft palate patients after palatal closure

Our findings indicated: (a) a simultaneous appearance of speech and hearing impairment at the same age for each cleft type post-surgically in our patients; (b) that the muscular and vomer complex rather than the anatomic extent of the cleft is a significant factor for speech outcome after surgical repair; and (c) that hypernasality is exacerbated by compensatory articulation.
