The aim of this study was to evaluate the amount and interrelationship of the soft and hard tissue changes after simultaneous maxillary clockwise rotation and mandibular setback surgery in skeletal class III malocclusion. The sample comprised of 16 adult patients who had anteroposterior skeletal discrepancy. These patients had received presurgical orthodontic treatment and surgical treatment which consisted of Le fort I Osteotomy and bilateral saggital split ramus osteotomy. The presurgical (T1) and postsurgical (T2) lateral cephalograms were evaluated. The computerized statistical analysis was carried out with SPSS/PC program. The results demonstrated a decrease in the vertical dimension in the soft and hard tissue. The nasolabial angle was increased and the mentolabial angle was decreased. The results showed also many statistically significant correlations(p<0.05). The lower lip closely followed the skeletal movement of the B- point in the horizontal plane. The double jaw rotation surgery can afford a good solution to solve the problems of class III malocclusion cases.

In nonsystemic vasculitic neuropathy, clinically only nerves are affected : there are no or few constitutional symptoms or serological abnormalities. The clinical and pathological features are those of an ischemic neuropathy caused by a necrotizing vasculitis of small arterioles. This is a case report of nonsystemic vasculitic neuropathy in a 22-year-old male who has the distal symmetric poIyneuropathy as a symptom of localized vsaculitis. The sural nerve biopsy showed a few myelin digestion chamber suggesting axonal degeneration. The patient was treated with steroid daily with gradual clinical and electorophysiological improvement.
