Spontaneous Growth of the Palatal Plates in the Cleft Lip and Palate.

This is a prospective study examining palatal casts from patients with unilateral cleft lip and palate (UCLP) in the first month of life, immediately before cheiloplasty, and immediately before palatoplasty. None of the patients receives presurgical orthopedics (nasoalveolar molding). In this prospective study, upper arch plaster models were taken 3 times during the treatment: in the first month of life (T1), before the cheiloplasty (T2), and before the palatoplasty (T3). Anatomic landmarks were defined and linear anthropometric measurements were obtained afterward. Dimensional analysis was performed using 3D software. Two-way analysis of variance followed by Tukey test was performed for statistical analysis. Tertiary, institutional. Twelve patients with UCLP of either sex with less than 1 month of life and without any other syndrome. No intervention was performed. Reduction of the cleft without using orthopedics apparatus. There was a statistically significant reduction in the cleft gap comparing T1 to T3. There was also a significant reduction in the intercanine width comparing T2 and T3, and T1 and T3. There was significant increase in the posterior arch width comparing T2 and T3, and T1 and T3. The palatal plate's width increased in all times analyzed. The palatal cleft narrows spontaneously as well in both midpoint and posterior point during the first 6 months of patient's treatment. This event was enhanced by cheiloplasty. This surgery might have a greater influence on the anterior arch width than in the posterior arch region.
