BACKGROUND This study is a quantitative evaluation of the influence of the mentolabial angle on perceived attractiveness and threshold values of desire for surgery. METHODS The mentolabial angle of an idealized silhouette male Caucasian profile image was altered incrementally between 84° and 162°. Images were rated on a Likert scale by pretreatment orthognathic patients (n = 75), lay people (...

Chin osteotomy is used in esthetic and functional procedure; genioplasty shows different surgical options as lineal osteotomy, curved osteotomy, segmental osteotomy and others for different conditions of the face. This communication shows the use of two surgical guides used in a patient with extremely facial asymmetry; the surgical plan was realized in a stereolithographic biomodel. The first s...

In addition to functionally correcting skeletal facial deformities, orthognathic surgery also has a great impact on aesthetics and proportions. However, patients who have soft tissue changes, such as flaccidity, may not achieve an ideal result, require complementary surgical techniques that promote aesthetic refinement. The literature less invasive is limited, therefore, this work aims report t...

OBJECTIVES This paper proposes Han's ratio as an objective and quantitative comparative result obtained from pre and postoperative data in patients with a mandibular angle reduction. MATERIALS AND METHODS Thirty patients, 12 men and 18 women, who visited the Department of Oral and Maxillofacial Surgery with the chief complaints of skeletal mandibular prognathism and prominent mandibular angle...

Video imaging is an important emerging technology in planning orthognathic surgery and educating patients about the esthetic effects of treatment. The presurgical cephalograms of 56 patients, 41 with mandibular advancement alone and 15 with mandibular advancement plus genioplasty, were digitized, and the computer-generated soft tissue "line drawing" predictions were compared with the actual pos...
