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.
