Insights

Early palate closure using the Sommerlad protocol resulted in excellent speech and velopharyngeal function (VPF) outcomes by age 5. This technique demonstrated reduced need for speech therapy and secondary surgeries for cleft palate patients.

Area of Science:

  • Craniofacial Surgery
  • Pediatric Otolaryngology
  • Speech Pathology

Background:

  • Velopharyngeal dysfunction (VPD) and speech impediments are common challenges following cleft palate repair.
  • The Sommerlad protocol for palate closure aims to optimize speech outcomes through early intervention and specific surgical techniques.

Purpose of the Study:

  • To evaluate speech and velopharyngeal function (VPF) outcomes at age 5 in children who underwent early complete palate closure using the Sommerlad protocol.
  • To analyze surgical characteristics associated with these outcomes.

Main Methods:

  • A retrospective, descriptive, cross-sectional study of 391 patients who underwent palate repair between 1993 and 2006.
  • Surgical intervention involved lip and vomerine flap repair (3 months) and palate closure (mean 6.6 months) using radical muscle dissection and retropositioning.
  • Speech and VPF outcomes were assessed using the Cleft Audit Protocol for Speech-Augmented (CAPS-A), yielding Velopharyngeal Composite (VPC) and articulation scores.

Main Results:

  • 97% of patients achieved adequate VPF (VPC-SUM CAPS-A score of 0).
  • 73% had no cleft articulation difficulties; bilateral cleft lip and palate (BCLP) group showed poorer articulation.
  • Low rates of secondary speech surgery (2.6%) and fistula repair (10.7%) were observed. Levator muscle quality and retropositioning correlated with VPF outcomes.

Conclusions:

  • Complete palate closure around 6 months via the Sommerlad technique yields excellent VPF and speech outcomes at age 5.
  • This approach appears to require less speech therapy and fewer secondary surgeries compared to other reported methods.
  • The study establishes the Sommerlad protocol as a benchmark for achieving superior speech results in cleft palate patients.
