OBJECTIVES To adequately perform orthognathic surgery procedures, it is from basic interest to understand the morphologic changes caused by orthognathic surgery. Anthropometric analyses of standardized frontal view and profile photographs could help to investigate and understand such changes. STUDY DESIGN We present a pre- to postoperative evaluation of orthognathic surgery results based on a...

OBJECTIVE To characterize revision surgery following V-Y subcutaneous tissue pedicle advancement flap repair of large upper lip skin defects. METHODS Retrospective review of upper lip skin defects at least 3.0 cm(2) in area that were reconstructed with a V-Y subcutaneous tissue pedicle advancement flap at an academic tertiary care center. Depth and area of the defect, as well as involvement o...

Female choice experiments were used to investigate the effect of relative male age on mating success in D. melanogaster. Experiments were conducted with a Canton-S (CS) strain, in which two virgin males of different ages (2, 4, or 8 days old) were offered to virgin females. Older males were found to be more successful under competitive conditions in another group of experiments, vermilion (v) m...

Sometimes we see patients with disappearing vermilion totally or in some parts. It seems that the marginal skin has advanced to the lip surface with the same color. It occurs mainly in lower lip. The majority of patients had history of recurrent herpes labialis on their lips, in the same location as disappearing vermilion. Disappearing vermilion is not accompanied by any change in consistency o...

Vermilion red, mercury sulphide (a-HgS), was one of the most important reds in art and its use as a pigment dates back to Antiquity. In medieval Europe, it could be mined as cinnabar, or produced as vermilion by heating mercury with sulphur. This work aims to study the production of synthetic vermilion as a medieval pigment and to confirm which was the source (mineral or artificial) of the reds...

Previous studies based on allozyme variation have found little evidence for genetic differentiation in Drosophila simulans. On the basis of DNA sequence variation at two nuclear loci in four African populations of D. simulans, we show that there is significant structure to D. simulans populations within Africa. Variation at one of the loci, vermilion, appears to be neutral and supports an easte...

PURPOSE This study describes 77 small vascular lesions on the lips of 74 children and adolescents. RESULTS Of the 77 lesions, 70% were on the lower lip and 30% on the upper. The diameter range was 0.5-5.0 mm (mean 1.4 mm). On both lips the lesions were in the vermilion zone, close to the border with the skin. The surface of the lesions was smooth and slightly raised, and varied in color from ...

BACKGROUND The vermilion plays an important role in both the aesthetic and functional aspects of facial anatomy. Due to its structural features, the complete excision of vascular anomalies on the vermilion is challenging, making it difficult to determine the appropriate treatment strategy. Thus, the authors analyzed the results of surgical treatment of vascular anomalies on the vermilion. MET...
