Recently, families of children with cleft palate often ask whether the younger the better and whether it is as young as about 6 months? However, from the perspective of the maxillary development and anatomy of infants and children, the palate of infants and children around 6 months to 10 months of age is very small, with a thin and narrow mucoperiosteal flap, and after surgery, due to the scar growth of the palate, it is obvious that the growth of the palatal plate width is limited, which results in maxillary dysplasia. The majority of studies have concluded that the mid-facial hypoplasia (commonly referred to as “geodysostosis” in common language) occurs during rapid growth, especially after the age of 8 years. This deformity obviously affects the child’s facial appearance and bite, and most of them need to undergo more invasive orthognathic surgery. The surgery can improve the pronunciation as much as the 6-month-old children. However, in order to restore good pronunciation besides age, it is more important to choose the surgical method. We started functional cleft palate revision 5 years ago, focusing on the reconstruction of the palatopharyngeal cricothyroid muscle. We recommend that the best age for cleft palate (either simple soft palate or complete cleft lip and palate) is around 10 months of age – 1.5 years (1.5 years refers mainly to severe bilateral cleft palate).
