Chin surgery, was initially described, for, the treatment of facial abnormalities, advancing the mandibular symphysis; achieved anterior displacement of the base of the tongue showing some value in the treatment of snoring and obstructive sleep apnea, and achieved adequate lip competence.

solution to this, design and planning the advances of the chin. Materials and Methods Patients operated in the service of Maxillofacial Surgery, Specialist Hospital, ‘‘Dr. Bernardo Sepulveda ’’XXI Century National Medical Center, during the period of 2015–2019, orthodontically compensated patients, with labial incompetence and Class II skeletal. Sixty-five patients were operated during this period, and eight cases are presented. Results Lip competition, osseointegration of the segments is observed, with a proper projection of the lower third, no nerve or vascular damage in the area. Conclusions The design of the osteotomy is for orthodontically compensated patients with labial incompetence and Class II skeletal, giving a result mandibular lengthening. The BEM achieved adequate lip competence demonstrated by an interlabial gap of 0 mm, achieved adequate osseous consolidation of the fracture site with a more harmonious facial balance and profile, without nerve or vascular damage with spectacular results.
