Abstract:

Objective To analyze the training technique, intervention timing, and other related factors involved in the speech therapy delivered to cleft patients with velopharyngeal competence after surgery. Methods A retrospective study was conducted on 32 patients who received phonology-articulation speech therapies during 2012 to 2013 in Dept. of Cleft Lip and Palate, West China Hospital of Stomatology, Sichuan University. All patients achieved normal speech one year after therapy. Information collected included the types and number of consonant articulation error, the overall period of training, the interval between surgery and speech training, and the age during speech training. Statistical analyses were performed in SPSS 16.0. Results Ten patients received less than five sessions of training, seventeen received six to ten sessions, and five received eleven to twenty sessions. The number of sessions was positively correlated with the number of errors (r_s=0.394, P=0.026). On the average, each additional error cost another 0.570 session for correction (confidence interval: 0.137-1.004). Moreover, the number of sessions was negatively correlated with age (P=0.055). Patients between 5 to 10 years old took significantly lesser sessions than those above 10 years. No correlation was found between the number of sessions and the interval between surgeries and trainings. Conclusion Appropriate speech therapy efficiently rehabilitate the speech condition of cleft patients with velopharyngeal sufficiency after surgery. The number of errors is directly proportional to the number of sessions needed. Patients above 10 years require more sessions than those less than 10 years.
