摘要: Abstract The bilateral sagittal split osteotomy (BSSO) and high oblique (HSSO) are common techniques for mandibular movement in orthognathic surgery. aim of this study was to evaluate the influence both techniques, as well distances directions, on position temporomandibular joint (TMJ). A total 80 movements were performed 20 fresh human cadaver heads, four each head. Pre- postoperative cone beam computed tomography used plan surgical procedure analyse TMJ. Reference measurements included anterior, superior, posterior spaces, intercondylar angles axial coronal planes, sagittal, coronal, angulations proximal segment. Only minor differences found between BSSO HSSO particularly terms angle plane (P
