Asymmetric mandibular prognathism: outcome, stability and patient satisfaction after BSSO surgery. A retrospective study.

Purpose: To investigate surgical outcome, long-term stability, the time course of relapse, neurosensory disturbances, and patient satisfaction after BSSO for correction of mandibular asymmetry. Another objective was to examine whether osteotomies for transverse rotation of the distal segment represent an increased risk for nerve injury.

Subjects And Methods: In a retrospective study lateral and postero-anterior cephalograms, information from patient files and questionnaires were analysed for 38 patients having more than 4 mm asymmetry at the chin pre-treatment (mean 8.

Patients offered orthognathic surgery: why do many refrain from treatment?

Aim: To examine factors associated with patients' decision to decline surgery.

Material/methods: Of 470 consecutive patients referred to the University of Oslo from 2007 to 2009, a sample of 160 subjects who had not undergone surgery was identified and contacted. 236 operated patients from the same period served as a comparison group.

Extraoral vertical subcondylar osteotomy with rigid fixation for correction of mandibular prognathism. Comparison with bilateral sagittal split osteotomy and surgical technique.

Purpose: The aim was to compare outcome after extraoral vertical subcondylar osteotomy (EVSO) with rigid fixation and bilateral sagittal split osteotomy (BSSO) for correction of mandibular prognathism. The objectives were to examine treatment factors, postoperative results, and long-term stability. The surgical technique for EVSO is presented in detail.
