Summary

Maxillary advancement surgery generally does not impact velopharyngeal function. Patients with good pre-operative function maintained it post-surgery, though some cleft palate patients experienced minor speech changes.

Area of Science:

  • Investigates the impact of surgical interventions on speech and velopharyngeal function.
  • Focuses on craniofacial surgery and its effects on speech production.

Context:

  • Maxillary advancement is a surgical procedure to correct midface retrusion.
  • Understanding its effects on velopharyngeal function is crucial for patient outcomes, especially in cleft palate cases.

Purpose:

  • To assess velopharyngeal function changes following maxillary advancement surgery.
  • To evaluate the impact on speech and velopharyngeal competence in patients with cleft palate and maxillary retrusion.

Summary:

  • Ten patients underwent maxillary advancement surgery.
  • Pre- and post-operative assessments included cephalometry, nasopharyngoscopy, and speech analysis.
  • No significant changes in overall speech or velopharyngeal competence were observed, although cleft palate patients showed slight hypernasality and nasal emission.

Impact:

  • Results suggest that maxillary advancement is safe for velopharyngeal function in patients with adequate pre-operative function.
  • Highlights the need for careful monitoring in cleft palate patients undergoing this procedure.
  • Provides valuable data for surgeons and speech-language pathologists managing these complex cases.
