A Comparative Effectiveness Study of Speech and Surgical Outcomes: Study Overview

Area of Science:

• Craniofacial surgery
• Speech-language pathology
• Pediatric healthcare outcomes

Background:

• Cleft palate repair involves complex surgical techniques with varying speech outcomes.
• The role of early intervention speech-language (EI-SL) services in optimizing speech development post-palatoplasty is not fully elucidated.
• The Cleft Outcomes Research NETwork (CORNET) provides a platform for multi-center research in cleft care.

Purpose of the Study:

• To compare speech outcomes and fistula rates between straight-line closure with intra-velar veloplasty (IVVP) and Furlow Double-Opposing Z-palatoplasty (Furlow Z-plasty).
• To assess practice variations in the use of EI-SL services for children with cleft palate.
• To explore the association between EI-SL services and speech outcomes in this population.

Main Methods:

• A prospective, longitudinal, observational, multi-center study involving 1247 children with cleft palate.
• Comparison of IVVP and Furlow Z-plasty based on surgeon's standard protocol.
• Primary outcome: perceptual ratings of hypernasality at age 3; secondary outcomes: fistula rate, speech production, quality of life. Statistical analysis using generalized estimating equations with propensity score weighting.

Main Results:

• Recruitment completed, with 80% retention and 562 children finishing 3-year speech assessments.
• Data analysis is ongoing to determine the comparative effectiveness of palatoplasty techniques and the impact of EI-SL services.

Conclusions:

• The study addresses critical questions regarding the effectiveness of common palatoplasty techniques.
• CORNET's infrastructure will facilitate future research in comprehensive cleft care.
• Findings will inform clinical practice and improve outcomes for children with cleft palate.
