Abstract

It was found that there was a group of patients with repaired cleft palate who demonstrated a discre­pancy between aerodynamic assess­ment of velopharyngeal (VP) adequa­cy and clinical judgement of nasal resonance. The aim of this work is to study such group of patients in order to understand and explain this discre-pancy.This study comprised 37 sub­jects divided into two groups. The first group comprised 12 patients with the diagnosis of repaired overt or submu-cus cleft palate with an age range of 5 to 25 years (mean age = 13 years). This group showed an audible degree of hypernasality in their speech while they have adequate VP port area by aerodynamic measures. The second group (n = 25) comprised age and sex matched normal subjects who demonstrated normal resonance of speech. All the subjects were as­sessed subjectively for the degree of open nasality on a 4-point scale and objectively by acoustic and aerody­namic studies. Acoustic studies demonstrated a highly significant difference in the nasalance scores between both groups. Aerodynamic studies demon­strated a statistically non-significant difference concerning nasal flow and intra-oral and nasal pressure findings between both groups. While, on the other hand, the timing of both the na­sal flow and the intra-oral pressure showed highly significant difference between both groups. Also, the nasal flow peak show a highly significant shift to the right with delay in flow in relation to the intra-oral pressure.
