Abstract
The aim of this study is to describe the importance of osteodistraction with transpalatal distractors for treating transversal maxillary hypoplasia in patients with cleft and lip palate. The participants were 17 patients (9 females and 8 males) with cleft lip and palate. Among these, 10 presented unilateral cleft lip and palate, 4 bilateral cleft lip and palate, and 3 cleft palate only. All patients experienced a satisfactory palatal expansion and crossbite correction. The mean lengthening was 12.7 mm. The average increase of intercanine distance, intermolar distance, maxillary transverse dimension (MTD), facial transverse dimension (FTD) was 12.16, 8.45, 1.77, and 1.67 mm, respectively. The clinical follow-up was 29.7 months (range: 6-61 months). Palatal distraction is a safe and successful alternative for treating maxillary transversal alterations in patients with cleft lip and palate. This technique facilitates the establishment of an adequate transverse dimension of maxillary, and consequently a proper dental occlusion.
