Summary: Craniofacial microsomia is a broad term that covers a variety of craniofacial malformation conditions that are caused by alterations in the derivatives of the first and second pharyngeal arches. In general terms, diverse therapeutic alternatives are proposed according to the growth stage and the severity of the alteration. When craniofacial growth has concluded, conventional orthognathic surgery (Le Fort I osteotomy, bilateral sagittal split osteotomy, and genioplasty) provides good alternatives for MI and MIIA type cases. Reconstruction of the mandibular ramus and temporomandibular joint before orthognathic surgery is the indicated treatment for cases MIIB and MIII. The goal of this article is to establish a surgical treatment algorithm for orthognathic surgery on patients with craniofacial microsomia, analyzing the points that allow the ideal treatment for each patient to be chosen.
