Speech disorder correction after cleft palate repair with levator veli palatini retropositioning / 中国组织工程研究

ABSTRACT

BACKGROUND:Cleft palate repair with levator veli palatini retropositioning can achieve good effects on pharyngeal function and voice quality by dissecting the muscle and rebuilding the muscle function only at the incision, without opening the mucoperiosteal flap, OBJECTIVE: To investigate the clinical effects of cleft palate repair with levator veli palatini retropositioning versus traditional surgery treatment on speech disorder correction. METHODS:Totaly 176 children with cleft palate were randomly assigned into treatment group and control group, 88 cases in each group. Patients were subjected to traditional surgery treatment in the control group and levator veli palatini retropositioning in the treatment group. RESULTS AND CONCLUSION:The postoperative speech inteligibility in the treatment group and the control group were 81.8% and 54.5%, respectively, and there was a significant difference between the two groups (P < 0.05). After cleft palate repair, the folowing indicators were al improved in the two groups, including soft palate functional length at static state and when pronouncing, and soft palate elevation angle (P < 0.05), and moreover, these indicators were better in the treatment group than the control group (P < 0.05). Scores on high nasal tone and rhinorrhea tone were decreased significantly in the two groups after repair, and the scores were significantly lower in the treatment group than the control group (P < 0.05). These findings indicate that cleft palate repair with levator veli palatini retropositioning can effectively rebuild soft palate function and perfect velopharyngeal competence in patients, which is of great significance for speech disorder correction and voice quality recovery.
