Insights
Early cleft palate surgery at 6 months significantly reduces velopharyngeal insufficiency by age 5 compared to 12 months. This benefits speech outcomes in infants with isolated cleft palate.
Area of Science:
- Craniofacial Surgery
- Pediatric Otolaryngology
- Speech-Language Pathology
Background:
- The optimal timing for primary surgery in infants with isolated cleft palate remains unclear regarding long-term outcomes.
- Key areas of investigation include speech, hearing, dentofacial development, and patient safety.
Purpose of the Study:
- To compare the efficacy of primary cleft palate surgery at 6 months versus 12 months of age.
- To evaluate the impact of surgical timing on velopharyngeal function, speech development, hearing, and dentofacial outcomes.
Main Methods:
- A randomized controlled trial assigned 558 infants with nonsyndromic isolated cleft palate to surgery at 6 or 12 months.
- Speech and language therapists assessed velopharyngeal function via standardized recordings at 5 years of age.
- Primary outcome: velopharyngeal insufficiency (VPI) score ≥4 at age 5; secondary outcomes included speech, hearing, dentofacial development, and complications.
Main Results:
- Fewer infants in the 6-month group (8.9%) experienced VPI at age 5 compared to the 12-month group (15.0%), a statistically significant difference (RR 0.59, P=0.04).
- Postoperative complications and serious adverse events were infrequent and comparable between the two groups.
- Speech recordings were analyzed from 83.6% of the 6-month group and 81.6% of the 12-month group.
Conclusions:
- Primary cleft palate surgery at 6 months of age leads to a lower incidence of velopharyngeal insufficiency at 5 years compared to surgery at 12 months.
- This earlier surgical timing appears beneficial for speech outcomes in infants with isolated cleft palate.
- The study was conducted in well-resourced settings and funded by the National Institute of Dental and Craniofacial Research.
Background:
Among infants with isolated cleft palate, whether primary surgery at 6 months of age is more beneficial than surgery at 12 months of age with respect to speech outcomes, hearing outcomes, dentofacial development, and safety is unknown.
Methods:
We randomly assigned infants with nonsyndromic isolated cleft palate, in a 1:1 ratio, to undergo standardized primary surgery at 6 months of age (6-month group) or at 12 months of age (12-month group) for closure of the cleft. Standardized assessments of quality-checked video and audio recordings at 1, 3, and 5 years of age were performed independently by speech and language therapists who were unaware of the trial-group assignments. The primary outcome was velopharyngeal insufficiency at 5 years of age, defined as a velopharyngeal composite summary score of at least 4 (scores range from 0 to 6, with higher scores indicating greater severity). Secondary outcomes included speech development, postoperative complications, hearing sensitivity, dentofacial development, and growth.
Results:
We randomly assigned 558 infants at 23 centers across Europe and South America to undergo surgery at 6 months of age (281 infants) or at 12 months of age (277 infants). Speech recordings from 235 infants (83.6%) in the 6-month group and 226 (81.6%) in the 12-month group were analyzable. Insufficient velopharyngeal function at 5 years of age was observed in 21 of 235 infants (8.9%) in the 6-month group as compared with 34 of 226 (15.0%) in the 12-month group (risk ratio, 0.59; 95% confidence interval, 0.36 to 0.99; P = 0.04). Postoperative complications were infrequent and similar in the 6-month and 12-month groups. Four serious adverse events were reported (three in the 6-month group and one in the 12-month group) and had resolved at follow-up.
Conclusions:
Medically fit infants who underwent primary surgery for isolated cleft palate in adequately resourced settings at 6 months of age were less likely to have velopharyngeal insufficiency at the age of 5 years than those who had surgery at 12 months of age.
