This study presents the results of surgically assisted rapid palatal expansion done on an outpatient basis in 19 patients with a mean age of 30 years. Postsurgical and postorthodontic evaluation (mean, 2.4 years) showed a mean relapse rate of 8.8% in the canine region, 1% in the premolar region, and 7.7% in the molar region. These results show that the(More)
PURPOSE Because neurosensory deficit is commonly reported by patients after orthognathic surgery, it is important to know how accurately patients can report their own sensory deficit. This analysis compares the results of objective neurosensory tests with the results of a subjective patient questionnaire. MATERIALS AND METHODS Before and 6 months after(More)
PURPOSE The purpose of this analysis was to compare the frequency and severity of nerve damage with rigid and wire fixation in patients participating in a prospective, randomized clinical trial. PATIENTS AND METHODS One hundred twenty-six patients who required a bilateral sagittal split osteotomy and mandibular advancement were randomly assigned to(More)
Intraoperative maxillary blood flow was measured using laser Doppler flowmetry (LDF) in two groups of patients undergoing orthognathic surgery. Group 1 (n = 14) consisted of patients undergoing Le Fort I osteotomy and group 2 (n = 8) consisted of patients undergoing isolated mandibular osteotomies. In group 1, the mean gingival blood flow (GBF) decreased(More)
OBJECTIVE The effects of orthognathic surgery on temporomandibular disorders may be related to the surgical method that is used. Specifically, it has been suggested that the choice of stabilization technique may play a major role in the functional outcome of mandibular advancement surgery. The purpose of this study was to prospectively compare long-term (2(More)
The proper alignment of the proximal and distal segments after the sagittal split ramus osteotomy (SSRO) has been a major concern since this procedure was first performed. Because of this problem, a comparison was made between a superior border wiring technique and an inferior border wiring technique. This involved the preoperative and postoperative lateral(More)
The purpose of this analysis was to identify a set of predictor variables that are prospectively related to postsurgical outcomes. Specifically, psychosocial characteristics were sought to predict postsurgical outcomes. The 5 Revised Symptom Checklist-90 (SCL-90-R) scales, the neuroticism score of the Eysenck Personality Inventory (EPI), the psychosocial(More)
Having undergone mandibular augmentation using several osteotomy techniques, 12 patients were evaluated for long-term sensory changes in the mental nerve distribution. The mean follow-up period was 32 months. The evaluation included both subjective and objective testing. Objectivity was achieved via the two-alternative forced-choice technique in testing(More)
PURPOSE Controversy exists regarding management of the descending palatine artery (DPA) during Le Fort I osteotomy. Some surgeons advocate preserving the DPA, and others ligate the vessels. The purpose of this study was to evaluate maxillary gingival blood flow (GBF) during Le Fort I osteotomy in a sample of patients with and without ligation of the DPA. (More)
