Abstract

The aim of this study was to describe a surgical technique that can be used to solve dentofacial deformities in cleft palate patients with maxillary hypoplasia in order to increase maxillary alveolar bone width, without modifying the skeletal base, and therefore, keeping the velopharyngeal function unaltered. Four patients with a history of cleft palate not associated with syndrome and treated under conventional surgical protocol during their childhood, underwent PAOO surgery incorporating L-PRF, followed by an accelerated orthodontic treatment with checkups every two weeks. All patients reached the desired occlusion without modifying their skeletal bases and velopharyngeal function. Orthodontic treatments were finished between 10 and 14 months after surgery without complications. There were no observed complications in the velopharyngeal postsurgical function and an increase in the arch width was achieved in all cases, along with a reduced orthodontic treatment time. The clinical results obtained confirm that PAOO technique is a safe and reliable complement to orthognathic surgery in the surgical treatment of cleft patients. By increasing the perimeter of the maxillary dentoalveolar ridge, the segmentation of the maxilla could be avoided, increasing the post operatory stability of these patients.
