Speech Outcomes Following Operative Management of Velopharyngeal Dysfunction (VPD) in Non-Syndromic Post-Palatoplasty Cleft Palate Patients.

Objective: Approximately 30% of patients with a history of repaired cleft palate (CP) go on to suffer from velopharyngeal dysfunction (VPD). This study discusses the operative management of VPD and postoperative speech outcomes in a cohort of CP patients.

Setting: An academic tertiary pediatric care center.

Methods: Retrospective cohort study.

Patients: Patients with history of repaired CP (Veau I-IV) who underwent operative management of VPD between January 1st, 2010 and December 31st, 2020. Operative modalities were posterior pharyngeal flap (PPF), sphincter pharyngoplasty (SPP), Furlow palate re-repair, and buccal myomucosal flap palate lengthening (PL).

Outcome measures: The primary outcome measure is postoperative speech improvement evaluated by the Pittsburgh Weighted Speech Scale (PWSS).

Results: 97 patients met inclusion criteria. 38 patients with previous straight-line primary palatoplasty underwent Furlow re-repair; these patients were significantly younger (7.62 vs 11.14, P < .001) and were more likely to have severe VPD per PWSS (OR 4.28, P < .01, 95% CI 1.46-12.56) when compared to VPD patients with previous Furlow repair. 21.1% of these patients required an additional non-revisional VPD procedure. The remaining patients underwent a non-revision procedure (26 PPF, 22 SPP, 11 PL); all experienced significant (P < .001 on paired t-test) reductions in PWSS total and subgroup VPD severity scores without difference in improvement between operation types. SPP was statistically associated with all-cause complication (OR 2.79, 95% CI 1.03-7.59, P < .05) and hyponasality (OR 3.27, 95% CI 1.112-9.630, P < .05).

Conclusion: Furlow re-repair reduced need for additional VPD operations. Speech outcomes between non-revisional operations are comparable, but increased complications were seen in SPP.
