Palatal Re-Repair With Z-Plasty in Treatment of Velopharyngeal Insufficiency of Syndromic and Nonsyndromic Patients With Cleft Palate

Background: Velopharyngeal insufficiency (VPI) often results from palatal shortening or insufficient levator function after cleft palate repair.

Aims: To assess the efficacy of palatal re-repair with Z-plasty in treatment of VPI for patients with isolated cleft palate (ICP).

Methods: This retrospective analysis comprised 130 consecutive patients who had ICP with VPI that required Z-plasty as secondary surgery between 2008 and 2017. Pre- and post-operative evaluation of velopharyngeal function was done perceptually and instrumentally by Nasometer.

Results: Median patient age at Z-plasty was 6.8 years (range 3.0-20.1). Of the 130 patients, preoperatively VPI was severe in 73 (56%), mild-to-moderate in 55 (42%), and borderline in 2 (2%). Postoperatively, 105 (81%) of patients achieved adequate (normal or borderline) velopharyngeal competence and 16 (12%) required second operation for residual VPI. The success rate was 84% in nonsyndromic patients, 79% in nonsyndromic Pierre Robin sequence patients, and 58% in syndromic patients. In syndromic children, the speech outcome was significantly worse than in nonsyndromic children (P = 0.014). Complications included wound healing problems in 3 patients (2%), mild infection in 1 patient (1%), postoperative bleeding in 1 (1%), and postoperative fistula in 2 (2%).

Conclusion: Palatal re-repair with Z-plasty is a safe operation for VPI correction in patients with ICP with a success rate of 81%. In syndromic patients, the procedure did not seem to work as well as in nonsyndromic patients.
