Pre-surgical Infant Orthopaedics (IO) did not significantly impact consonant production in children with Unilateral Cleft Lip and Palate (UCLP) by 18 months. Both UCLP groups showed fewer consonant types than controls.

Area of Science:

  • Speech-Language Pathology
  • Craniofacial Anomalies
  • Pediatric Development

Background:

  • Unilateral Cleft Lip and Palate (UCLP) can affect speech development.
  • Early intervention strategies aim to improve outcomes for children with UCLP.
  • The role of Infant Orthopaedics (IO) in speech development requires further investigation.

Purpose of the Study:

  • To evaluate the effect of pre-surgical Infant Orthopaedics (IO) on consonant production at 18 months in children with UCLP.
  • To compare consonant production in UCLP children with and without IO to typically developing controls.

Main Methods:

  • A cohort study comparing 20 children with UCLP, ten receiving IO and ten not.
  • Soft palate repair was performed at 6.3 months; hard palate remained unrepaired.

  • Phonetic transcriptions of consonants were analyzed from audiotape recordings of 9 children per group at 18 months.

    • Main Results:

    • No significant difference in the number of consonant tokens or types between UCLP groups (with and without IO).
    • Both UCLP groups produced significantly fewer consonant types than the control group.
    • No significant differences in plosive manners or places of articulation between UCLP groups; controls had higher frequency of bilabial and dental plosives.

    Conclusions:

    • Pre-surgical IO did not demonstrate a significant benefit for consonant production at 18 months in children with UCLP.
    • Children with UCLP, regardless of IO, exhibited delayed consonant development compared to controls.
    • Further research is needed to explore long-term speech outcomes and the efficacy of different interventions for UCLP.
