Abstract

Individuals with repaired cleft lip and palate (CLP) may be at risk for decreased tactile sensitivity in the oral cavity due to surgical intervention and scarring. Three research questions were proposed: 1) Do adults with repaired CLP demonstrate reduced palatal sensitivity compared to a control group? 2) Do adults with repaired CLP exhibit longer speech segment durations of alveolar-palatal targets? 3) Is there a relationship between palatal sensitivity and duration of speech segment durations? Tongue and alveolar-palatal tactile thresholds were determined for five adults with repaired CLP and five adults without CLP, using Semmes-Weinstein monofilaments. Normalized speech segment durations were determined for the alveolar-palatal sounds (/s/, /sh/, /t/, and /l/). The difference between groups for tactile thresholds approached significance (p=.0741). Within subjects, significant differences occurred between the tongue and alveolar-palatal sites. Correlations among tactile thresholds and speech segment durations were not significant. Clinical implications are discussed.
