Objectives: Orthognathic surgery is a treatment method that repositions the maxilla and mandible to correct severe skeletal deformities and malocclusions, thereby improving anatomical relationships, functionality, and facial aesthetics. Studies have reported that Class III malocclusion is observed in 73.9% of patients with an isolated cleft palate. The aim of this case report is to present the orthodontic and orthognathic surgical treatment stages and outcomes of a patient with Class III malocclusion and an isolated cleft palate.
Case Report: The patient’s treatment plan included fixed orthodontic treatment with the extraction of teeth 15 and 25, followed by orthognathic surgery. During the fixed orthodontic treatment, the maxillary and mandibular arches were leveled, and decompensation was achieved, after which the patient underwent orthognathic surgery. In the surgical procedure, the maxilla was advanced by 6 mm using a single-piece Le Fort I osteotomy. Post-treatment cephalometric analysis yielded the following findings: SNA: 81.3°, SNB: 80°, ANB: 1.3°, SNGoGn: 27.4°, and IMPA: 86.4°
Conclusions: The aesthetic and functional dentofacial improvements achieved through fixed orthodontic treatment and orthognathic surgery in a patient with skeletal Class III malocclusion and an isolated cleft palate resulted in successful outcomes with high patient satisfaction.
