          Abstract

          This paper presents the treatment protocol of maxillofacial surgery in the rehabilitation process of cleft lip and palate patients adopted at HRAC-USP. Maxillofacial surgeons are responsible for the accomplishment of two main procedures, alveolar bone graft surgery and orthognathic surgery. The primary objective of alveolar bone graft is to provide bone tissue for the cleft site and then allow orthodontic movements for the establishment of an an adequate occlusion. When performed before the eruption of the maxillary permanent canine, it presents high rates of success. Orthognathic surgery aims at correcting maxillomandibular discrepancies, especially anteroposterior maxillary deficiencies, commonly observed in cleft lip and palate patients, for the achievement of a functional occlusion combined with a balanced face.

            Elimination of the residual alveolar cleft by secondary bone grafting and subsequent orthodontic treatment.

            A combined surgical/orthodontic procedure to eliminate the residual alveolar cleft by secondary bone grafting and subsequent orthodontic treatment is described. The operations have been carried out on 378 patients: 240 males and 138 females. Seventy-two patients had bilateral clefts, making a total of 450 grafted clefts. The optimal age for this secondary bone grafting has been found to be 9 to 11 years. In 292 of the cases, the canine had reached its final position in the arch, which allowed a four-group semiquantitative assessment of the newly obtained interdental septum on dental radiographs. The best results have been achieved in cases where the bone graft was carried out prior to the eruption of the canine. In this group, a normal (category I) interdental septal height was achieved in 64 percent and a slightly lower (category II) interdental septum in 32 percent. Interdental septa classified as type I and II are considered to be acceptable. The cleft space was closed in 90 percent of the cases. No significant difference between unilateral and bilateral cases was found. When the same procedure was carried out after eruption of the canine, the results were less favorable.

              Rehabilitative treatment of cleft lip and palate: experience of the Hospital for Rehabilitation of Craniofacial Anomalies/USP (HRAC/USP) - Part 1: overall aspects

              Cleft lip and palate is the most common among craniofacial malformations and causes several esthetic and functional implications that require rehabilitation. This paper aims to generally describe the several aspects related to this complex pathology and the treatment protocol used by the Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo (HRAC-USP) along 40 years of experience in the treatment of individuals with cleft lip and palate.
