OBJECTIVE In this study, we aimed to examine the relationship between chin deviation and the positional and morphological features of the mandible and to determine the factors that contributed to chin deviation in individuals with a unilateral cleft lip and palate (UCLP). METHODS Cone-beam computed tomography (CBCT) images of 28 adults with UCLP were analyzed in this study. Segmented three-di...

PURPOSE This study investigated the effect of the chin-down posture on the sequence of swallowing events in healthy adults. METHOD Sixteen healthy participants performed 45 5-ml thin liquid swallows during videofluoroscopy: 5 neutral head position, 30 chin-down posture, and then 10 neutral head position. Eight swallowing events were measured: the time of hyoid burst, bolus head in the pharynx...

In this paper, an improved method to extract the chin contour under different face poses is proposed. Several previous approaches have used active contour models(ACM) or snakes in front-view facial images. However, successful chin contour extraction for a wide range of face poses has seldom been mentioned. An algorithm based on an improved snake for chin contour extraction is presented here and...

Augmentation of the chin is a long-standing and effective technique for facial enhancement. We have used preformed expanded polytetrafluoroethylene (Gore-Tex) implants for chin augmentation for several years. For this study, we collectively pooled data detailing our experiences with this material. From January 1, 1998, to March 30, 2001, a total of 324 Gore-Tex chin implants were placed. No res...

BACKGROUND In East Asian countries, a prominent, long, and squared contour of the lower third of the face is considered unattractive, strong, and masculine. To change such a facial contour into an ovular contour, correction of the chin area is essential to accomplish the overall curve in the mandibuloplasty, and various methods for the horizontal reduction of the chin area have been suggested. ...

CONTEXT There have been many cases of medication-induced tremors. We report a patient who developed significant chin tremors after the administration of paroxetine. CASE REPORT A 68-year-old Vietnamese female with a past medical history including GIST and pancreatic cancer status post Whipple procedure and six months of adjuvant chemotherapy with gemcitabine presented with symptoms of anxiety...
