Pediatricians and surgeons generally recommend repair of cleft lip as soon as the infant's condition permits. In his recently published textbook of pediatric surgery, Swenson states: "Early repair is now universally advocated, with some difference as to actual age selected for operation. Repair 10-14 days after birth when feeding schedule has been established and a search for obscure anomalies has been completed is preferred." MacCollum et al. suggest that the lip be repaired "when the baby is 2.7 kg (6 lb) in weight or over, exhibits a steady gain in weight, is in good health and is 4 to 6 weeks of age." Thoroughgood and Fischer have recommended repair of unilateral cleft lip at the age of 12 hours.
