One Step Mandibular Midline Segmental Osteotomy, Genioplasty, and Sagittal Osteotomy as Strategy to Treat Facial Deformities.

Facial deformities are treated with various osteotomies; one of them is the median osteotomy of the mandibular symphysis. The combined use of other osteotomies offers advantages in addressing different anatomic alterations. This study aimed to analyze the performance of the mandibular midline osteotomy in a series of cases, used in conjunction with other mandibular osteotomies. A series of 9 cases was evaluated, including patients of both sexes, excluding those with incomplete records. Preoperative and postoperative variables were examined to determine indications and surgical sequence characteristics. Two patients presented temporomandibular joint symptoms in the postoperative phase and received minimally invasive treatment. No periodontal alterations were observed at the osteotomy sites, and all cases showed occlusal stability, concluding with standard orthodontic treatment. The results suggest that the described technique allows for predictable and stable occlusal outcomes in the treatment of facial deformities, making it a versatile tool with low complication rates.
