fa Proximal segment positioning with high oblique sagittal split osteotomy: indications and limits of intraoperative mobile cone-beam computerized tomography جراحی دهان، فک و صورت Oral and Maxillofacial Surgery پژوهشي Research <p> <strong>Objective </strong></p><p> The purpose of this study was to evaluate the indications and limits for intraoperative proximal segment positioning control by mobile cone-beam computerized tomography (CBCT). </p><p> <strong>Study Design</strong></p><p>  For mandible osteotomy in orthognathic surgery, the high oblique sagittal split osteotomy (HSSO) is our standard procedure. In 22 patients, positioning control of the proximal segment was performed during and after surgery to check this alternative osteotomy technique. </p><p> <strong>Results</strong></p><p>  The mean intercondylar distance increased 0.31 mm in all patients. No significant change of the condyle positions was found in the axial and coronal planes. In the sagittal plane a significant change was found. In 1 case, revision was required because of a lateral shifting of the condyles. </p><p> <strong>Conclusions</strong></p><p>  Intraoperative positioning control with CBCT is an effective and reliable method to avoid condyle malpositions. Only minor position changes occur when using HSSO in orthognathic surgery, without compromising temporomandibular joint function postoperatively. </p><hr><p></p><p> <strong>Source: </strong>Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology </p><p> <a href="http://www.oooojournal.net/article/S2212-4403(12)01676-8/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1624&slc_lang=fa&sid=1 Robin Seeberger 10031947532846007552 10031947532846007552 Yes Department of Oral and Maxillofacial Surgery, University Hospital Heidelberg, INF 400, 69120 Heidelberg, Germany Oliver C.
