Three-dimensional changes in the mandibular condyle in skeletal class III patients treated with orthognathic surgery: a systematic review.

This systematic review aimed to evaluate the available evidence on the incidence and quantification of 3-dimensional changes in mandibular condyles after orthognathic surgery by bilateral sagittal split osteotomy (BSSO), with or without maxillary surgery, in class III symmetrical or asymmetrical individuals. The databases PubMed, Lilacs, Web of Science, Embase, SciELO, Scopus, EBSCO, Cochrane, and Google Scholar were surveyed and the study was registered on the PROSPERO (CRD42022383594). The selected studies met the criteria established by the PICO model: 1: Population - individuals over 18 years of age with class III dentofacial skeletal deformities; 2: Intervention - orthognathic surgery using BSSO; 3: Comparison - condylar tomographic measurements (volume, thickness, height, and width) prior to the surgical procedure; and 4: Results - condylar tomographic measurements (volume, thickness, height, and width) at least 12 months after surgery.
