A morphometric study of age- and sex-dependent changes in eyebrow height and shape.

Background: Rejuvenation procedures of the periorbital region and the forehead, with the eyebrow as a key structure, are often performed in plastic surgery. There is no common consent on the changes of aging in this region and the consecutive treatment options. This study was designed to support the body of literature with a broader data basis about the natural changes of eyebrow position and its shape.

A 3D Morphometrical Evaluation of Brow Position After Standardized Botulinum Toxin A Treatment of the Forehead and Glabella.

Background: Botulinum toxin treatment for forehead wrinkles has been extensively studied and found to be a safe and reproducible procedure. However, the effect on the position of the eyebrows, which relies on the dynamic positioning of the treated muscles, has received less attention and has not been studied with 3-dimensional (3D) technology.

Objectives: The authors sought to evaluate the changes of eyebrow position after standardized botulinum toxin treatment of glabella or glabella and frontalis muscles with 3D imaging.

Prospective 3D analysis of facial soft tissue augmentation with calcium hydroxylapatite.

Background: Facial rejuvenation is an expanding field with an increasing number of treatment modalities. Several non-autologous filler materials are available for soft tissue augmentation. Calcium hydroxylapatite (CaOH) is aimed at increasing collagen neosynthesis and thereby producing long-term augmentation effects.

Complication assessment and prevention strategies using midfoot fusion bolt for medial column stabilization in Charcot's osteoarthropathy.

In Charcot's osteoarthropathy stabilization of the medial column of the foot was introduced in order to establish a stable foot and reduce the risk for amputation. This study was performed to analyze postoperative complications, define risk factors for those and develop strategies for prevention. Since bolt dislocation takes place frequently, it was aimed to predict an appropriate time point for bolt removal under the condition that osseous healing has occurred.

Aging Changes of the Male Lips-A Lesser Evil Than in Females?

Background: Although aging changes of the female perioral region and aesthetic procedures for perioral rejuvenation are described in literature, specific data for the male population are lacking. This study aims to evaluate perioral aging process in the male population to compare quality and quantity of the observed changes to the female population.

Methods: Magnetic resonance imaging (MRI) scans of 22 male subjects, were recruited into 2 age groups: young (20-35 years) and old (65-80 years) and the following parameters were measured: length of visible upper lip, thickness of upper lip at the level of vermilion border, thickness of upper lip at the level of the mid lip, and cross-section area of upper lip.
