This study describes an unusual case of mandibular asymmetry after fibula free flap reconstruction in a young man following major facial trauma that was corrected using a custom-made polyetheretherketone prosthesis. There is little information in the literature on the use of alloplasts to correct mandibular asymmetry as interest in 'aesthetic re-modelling' has traditionally focused on nasal, zy...

PURPOSE Objective quantifications of facial asymmetry in patients with Unilateral Condylar Hyperplasia (UCH) have not yet been described in literature. The aim of this study was to objectively quantify soft-tissue asymmetry in patients with UCH and to compare the findings with a control group using a new method. MATERIAL AND METHODS Thirty 3D photographs of patients diagnosed with UCH were co...

BACKGROUND Hemifacial microsomia (HFM) features hypoplasia and asymmetry in skeletal as well as soft tissue, and correction of the deformity is difficult in terms of aesthetic outcome. The purpose of this study is to examine the validity of an integrated treatment protocol for correction of this facial deformity. PATIENTS AND METHODS A retrospective study was performed on adult HFM patients w...

BACKGROUND Accurate preoperative planning combined with facial fat compartment augmentation can improve precision and balance in facial rejuvenation techniques. Understanding the concept of "facial shaping" with respect to symmetry and soft-tissue (fat) distribution preoperatively is critical to optimizing aesthetic outcomes in various face lift techniques. METHODS A review of 822 consecutive...

PURPOSE In this study, we evaluated the tonic vibration reflex (TVR) of the masseter muscles in patients with facial asymmetry. SUBJECTS AND METHODS The study was conducted with 10 volunteers without facial asymmetry and 12 orthognathic patients with facial asymmetry. Subjects were seated in a chair and held a stimulator composed of an electric motor and an acrylic bite block between the uppe...

Craniofacial morphology and asymmetry were compared before, during, and after puberty within and between patients with unilateral complete cleft lip and palate (UCCLP) and a non-cleft group. In the UCCLP group, the posterior cranial base and total cranial base were significantly shorter at all skeletal periods, the maxilla was significantly retruded and posteriorly rotated, and the mandible was...

For decades the relationships of twinning and alterations in body patterning, such as laterality and asymmetry, have been investigated. However, the tools to define and quantify these relationships have been limited and the majority of these studies have relied on associations with subjectively defined phenotypes. The emerging technologies of 3-dimensional (3D) facial scanning and geometric mor...

OBJECTIVE To investigate the laterality of the normal asymmetry of the human face, examining differences in laterality in relation to sex, growth stage, and skeletal classification. MATERIALS AND METHODS A total of 1800 Japanese subjects (651 males and 1149 females; mean age, 15 years 3 months; range, 4 years 2 months to 59 years 11 months) were selected. Individuals in the sample were catego...

METHODS: 59 experimental and 59 control facial images were obtained from the senior author’s practice. Experimental images included the following diagnoses (15 cleft lip, 15 facial aging, 12 ear deformity, 7 facial lesion, 6 HIV lipodystrophy, 3 facial asymmetry, 2 nasal deformity). Twenty standardized lookzone regions were mapped onto each facial image. 170 adult subject observers were recruit...

INTRODUCTION Synkinesis and facial asymmetry due to facial nerve palsy are distressing conditions that affect quality of life. Unfortunately, these sequelae of facial nerve palsy are unresolved. The aim of this study was to investigate the efficacy of a combination of biofeedback therapy and botulinum toxin A (BTX-A) injection for the management of synkinesis and asymmetry of facial muscles. ...
