Abstract
This is a cephalometric study performed with 318 lateral radiographs of 88 caucasian unilateral complete cleft lip and palate patients (53 males and 35 females) with ages ranging between 3 and 19 years. Lip surgery (cheiloplasty) was performed before the sixteen month of life and palatal surgery (palatoplasty) was performed until the forty eigth month of life. Using the cephalometric measurements SNA, SNB, SN.ANS and nasolabial angle, the study quantifies the longitudinal effects that cleft, cheiloplasty, palatoplasty, and orthodontic treatment induce upon facial growth. On the basis of the data obtained, it is Iiable to conclude that: maxillary retropositioning is a characteristic of early operated cleft patients that tends to worsen along growth; SNA and SN.ANS angles show a gradual decrease with time; and, SNB angle tends to increase along growth for both sexes.
