摘要

Objectives

To evaluate the effect of surgical timing of palatal closure on overall masticatory function in infants with cleft lip and/or palate (CL/P).

Materials and methods

In this randomized controlled trial, 60 children with cleft lip and/or palate (CL/P) were assessed at the Wilhelmina Children’s Hospital, University Medical Center Utrecht, the Netherlands. Participants were randomly assigned to early closure (Group A: 6–8 months) or late closure (Group B: 10–12 months). Chewing function was evaluated at 9, 13, and 17 months of age using the Mastication Observation and Evaluation (MOE) instrument, which scores eight components of mastication.

Results

No statistically significant differences were found in total MOE scores between groups at any time point. However, at 17 months, Group B showed significantly better lateral tongue movement than Group A (mean = 2.72, SD = 0.53 vs. mean = 2.45, SD = 0.51; p = .047).

Conclusions

Early palatal closure (6–8 months) does not improve overall mastication compared to late closure (10–12 months) in the first 17 months of life.

Clinical Relevance

Research on mastication in children with CL/P is limited. This study provides novel insights into functional outcomes of palatal surgery, supporting evidence-based refinement of cleft treatment protocols.

Trial Registration Number

The CLEFED study was approved by the Medical Ethics Committee of the University Medical Center Utrecht, The Netherlands (registration no: NTR3275). Date of registration: November 2011. Trial Register: https://www.trialregister.nl/trial/3125 (trial number: NTR3275)
