Nevus sebaceous (NS) is a benign neoplasm occurring mainly on the face and scalp. It commonly occurs as a solitary, well-demarcated lesion. This paper presents a case of multiple nevus sebaceous, which presented as multiple lesions occurring on the temporal scalp and on the contralateral side of the chin. Multiple NS have only rarely been reported.

The purpose of this study was to evaluate the position and shape of mental foramen in panoramic radiographs. For t his study, panoramic radiographs were obtained from the 200 adults and evaluated the position and shape of mental foramen. According to various positional changes in panoramic radiographs of the patients, the author also obtained panoramic radiographs from the 100 adults and then evaluated the positional and shape changes of mental foramen. The following results were obtained: 1. Shapes of mental foramen were observed elliptical(43.3%), round or oval(42.5%), unidentified(7.5%) and diffuse(6.7%) type in descending order of frequency. 2. Horizontal position of mental foramen were most frequently observed at the 2nd premolar area(54.2%), and area between the 1st premolar and 2nd premolar(43.1%), area between the 2nd premolar and 1st molar(2.7%), and at apex(9.7%), overlap with apex(1.9%), superior of apex(0.2%) in descending order of frequency. 4. According to various positional changes in panoramic radiographs of the patients, shape changes of mental foramen we re more obviously observed at the forward 10mm and chin down 10degrees positioned panoramic radiographs, And changes of horizo ntal and vertical position were observed in similar to compared with normal positioned panoramic radiographs.

The configuration of mandibular symphysis is likely to be dependent upon the genetic predeterminants and/or compensatory adjustments onto functional demands. The interrelation of morphological distinctives of symphysis in conjunction to the craniofacial skeleton had been scarcely anecdotal, therefore, the objective was to determine the correlation of morphological modifications between the mandibular symphysis and craniofacial complex. Lateral cephalometric headfilms of 212 subjects were employed for the conventional measurements. The proportion of chin height against chin depth length was referred as chin ratio, then, Low Symphysis (IS) and High Symphysis (HS) groups were turned out by means of the chin ratio. These samples yielded 35 in LS and 35 in HS groups. The data per capita were statistically analyzed and the following results were drawn ; 1. Overall characteristics of the craniofacial skeleton in HS group manifested hyperdivergence and LS group showed hypodivergence. 2. Gonial angle increased as chin ratio increased and was highly correlated to the chin ratio. 3. The chin ratio presented high correlation to the vertical face height, especially in terms of the chin height to anterior face height and the chin depth to posterior face height. 4. The morphological configuration of chin was hardly correlated with hyoid bone position.
