Abstract:
The reduction mandibular angleplasty is one of the most common aesthetic facial bone contouring surgery in the Oriental and the intraoral approach has been used commonly. However this method has some disadvantages because of anatomical restriction of operation field. We performed therefore the reduction of mandibular angle with endoscopic assistance in 15 patients of mandibular angle protrusion. Thirty patients of mandibular angle protrusion were randomly divided into control group (n=15) who received classic ostectomy and study group (n=15) who received endoscopically assisted ostectomy. We compared two groups in operative times, size of incision, duration of postoperative accommodation and satisfactory rate of doctors and patients. Size of incision was assessed as smaller in study group who received endoscopically assisted ostectomy than that of control group who received classic ostectomy on student t-test (5.50 + /-0.65 versus 4.70+/- 0.56, p< or= 0.01). Duration of postoperative accommodation was also assessed as shorter in study group on student t-test (5.07+/- 0.80 versus 4.00+/-1.00, p< or =0.01). There was no specific difference between 2 groups for operative time on x(2)-test (97.33+/- 12.22 versus 97.33+/-12.80, p=1.00). Satisfactory rate of cosmetic appearances were similar according to patients and surgeons. The postoperative course was satisfactory with smaller size of incision, shorter duration of postoperative accommodation and similar operative time and satisfactory rate of cosmetic appearances according to both patients and surgeons.
