For years, the notion of chin ptosis was somehow integrated with the concept of witch's chin. That was a mistake on many levels because chin droop has four major causes, all different and with some overlap. With this article, the surgeon can quickly diagnose which type and which therapeutic modality would work best. In some cases the problem is a simple fix, in others the droop can only be stab...

BACKGROUND Botox has been used primarily for treating rhytids of the upper face. Its use in the lower part of the face has been reported by several authors but there is a relative scarcity of information regarding the use of Botox in the chin and even fewer well-controlled studies in this area. This study reports the findings from a placebo-controlled trial of Botox for the treatment of chin rh...

BACKGROUND Women with elliptical faces are considered to be aesthetically appealing in Asia. Some men prefer this shape for themselves and choose to have their square-shaped face altered to an elliptical shape. To accomplish this, we perform an ostectomy that includes resection of the mandibular angle, splitting of the lateral cortex, and reduction in the width of the chin. METHODS Nineteen m...

It is commonly believed that upward/backward forces applied to the condyle by a chin-cap cause temporomandibular dysfunction (TMD). In the current study the long-term follow-up (2-11 years) of patients treated with a chin-cap was investigated regarding signs and symptoms of TMD. The treatment group consisted of 32 individuals who had a skeletal Class III malocclusion treated using chin-cap ther...

OBJECTIVE To investigate the dentoskeletal factors which may predict soft-tissue chin strain during lip closure. METHODS The pretreatment frontal and lateral facial photographs and lateral cephalograms of 209 women (aged 18-30 years) with Angle's Class I or II malocclusion were examined. The subjects were categorized by three examiners into the no-strain and strain groups according to the sof...

Purpose: To statistically evaluate circumpubertal changes in AP chin position and to predict the AP changes in chin position based on morphological indicators previouslyused to successfully predict true rotation. Method: A mixed-longitudinal sample of200 untreated subjects from the Montreal Growth Study was utilized, including 97females and 103 males between 10-13 and 12-15 year...

BACKGROUND Scarring following acne vulgaris is common and can be of profound psychosocial consequence. AIMS AND OBJECTIVES We have clinically noted a variant of acne scarring, overlooked by previous categorisation schemes, which we have denominated as papular acne scars of the nose and chin. We sought to characterise these novel entities further. MATERIALS AND METHODS Initially, we identifi...

Background: Although neurosensory disturbances after genioplasty have been evaluated in different studies, standardization for testing and grading of neurosensory injuries is lacking. For this reason, the incidence of neurosensory disturbance varies from 0% to 100%, depending on the definition of nerve damage, the sensitivity of the diagnostic test method, and the follow-up period. Therefore, t...

AIM To systematically search the literature and assess the available evidence for the influence of chin-cup therapy on the temporomandibular joint regarding morphological adaptations and appearance of temporomandibular disorders (TMD). MATERIALS AND METHODS Electronic database searches of published and unpublished literature were performed. The following electronic databases with no language ...

Lalit Bhutani in the last issue of the U L (45:67) has noted the relative sparing of the underside of the chin and the circumocular region and the upper lip in lepromatous patients and the more severe involvement of the malar eminence, the forehead, and the chin. He attributes this variation to the possible effect of photosensitivity. Sabin (Arch. Neurol. 20 [March 1969]; and U L 37 [1969]) des...
