Is distal segment ostectomy essential for stabilization of the condylar position in patients with facial asymmetry?

Background: The purpose of this retrospective study was to evaluate the postoperative change in the position and stability of the mandibular condyle after bilateral sagittal split ramus osteotomy (BSSRO) and BSSRO with distal segmental ostectomy (DSO) in patients with facial asymmetry using 3D computed tomography.

Methods: The condyles of the patient diagnosed with facial asymmetry were divided into the deviated side (DS) and the non-deviated side (NDS). Group I, which was treated with BSSRO only, and Group II, which additionally received DSO along with BSSRO, were superimposed on the condyle using the pre-and postoperative 3D CT.

Positional changes of the mandibular condyle in unilateral sagittal split ramus osteotomy combined with intraoral vertical ramus osteotomy for asymmetric class III malocclusion.

Objectives: In the present study, the effects of sagittal split ramus osteotomy (SSRO) combined with intraoral vertical ramus osteotomy (IVRO) for the treatment of asymmetric mandible in class Ⅲ malocclusion patients were assessed and the postoperative stability of the mandibular condyle and the symptoms of temporomandibular joint disorder (TMD) evaluated.

Materials And Methods: A total of 82 patients who underwent orthognathic surgery for the treatment of facial asymmetry or mandibular asymmetry at the Department of Oral and Maxillofacial Surgery, Dong-A University Hospital, from 2016 to 2021 were selected. The patients that underwent SSRO with IVRO were assigned to Group I (n=8) and patients that received bilateral SSRO (BSSRO) to Group II (n=10, simple random sampling).

Psychosocial Issues Related to Donor's Decision-Making in Living Donor Liver Transplantation.

BACKGROUND The aim of this study was to investigate the detailed motives, concerns, and psychological defensiveness of living liver donor candidates in a Korean population. MATERIAL AND METHODS We analyzed data of 102 donor candidates obtained from routine psychosocial evaluation for living donor liver transplantation (LDLT) using descriptive methods. Donor candidates completed 2 questionnaires regarding their motivations and concerns, as well as a validity scale, the K scale from the Minnesota Multiphasic Personality Inventory-2.
