Perceptual-Speech,Nasometric,and Cephalometric Results after Modified V-Y Palatoplasties with or without Mucosal Graft

Abstract

Objective

Although the goal of cleft palate (CP) repair is to achieve normal speech, no standard procedure ensures that patients' speech will be at the same level as speech in children without CP. In this study, postoperative speech outcomes following primary CP repair combined with or without a mucosal graft was analyzed in comparison with that of control subjects without CP.

Participants

Eighty-two patients who underwent modified V-Y palatoplasty with a mucosal graft on the nasal side for symmetrical muscular reconstruction during 2006-2012 (MG group) and 109 patients who previously underwent modified V-Y palatoplasty without a mucosal graft (non-MG group) were enrolled in this study. Speech data on 37 Japanese subjects without CP were used as a control.

Main outcome Measures

Perceptual rating of resonance and nasal emission and nasometry were carried out for all participants. Furthermore, cephalometric analyses were performed to assess postoperative velopharyngeal morphology and velar movement.

Results

Normal resonance was achieved at a significantly higher rate (90.3% of patients) in the MG group than in the non-MG group (68.8%) (P ≤ .01). The mean nasalance scores in the MG group were significantly lower (P ≤ .01) and were almost at the same level as in controls. Cephalometric analyses revealed a greater velar length and velar elevation angle during phonation in the MG group (P ≤ .01 and P ≤ .05, respectively).

Conclusions

Modified V-Y palatoplasty combined with a mucosal graft on the nasal side of the velum for symmetrical muscular reconstruction facilitates speech outcomes for children with cleft palate that are comparable with those for peers without CP.
