The purpose of the study is to explore the critical parameters determining the visual perception of postoperative facial symmetry. This study retrospectively included 24 patients with skeletal class III malocclusion and double-jaw orthognathic surgery (OgS). The patients were classified according to the outcome of subjective visual perception scores (SVPS) based on the postoperative frontal images by 10 orthodontists: symmetrical surgical outcome (S group, n=12) and facial asymmetry after surgery (A group, n=12)...

Atypical facial characteristics have been observed in many disorders associated with developmental disability. While autism spectrum conditions (ASC) have not previously been thought to be associated with a distinct facial phenotype, an emerging research literature is casting doubt on this assumption. The identification of differences in the facial phenotype of individuals with ASC may contribute to efforts to promote early identification of the condition and help elucidate etiological pathways. With the aim of identifying facial phenotypes associated with ASC, this commentary evaluated facial features purported to distinguish ASC from typical development...

INTRODUCTION: The purpose of our study was to describe a novel technique for reconstruction of orbital defects after maxillectomy using a non-anatomic titanium mesh suspension of orbital contents for both support and volume correction. This construct is then articulated with a layered fibula osteocutaneous free flap that restores orbital rim, zygoma, and maxillary alveolus. We herein present our application of this technique, including refinements over time and long-term outcomes. METHODS: A retrospective review was performed on 12 patients who underwent reconstruction of Brown class III orbitopalatomaxillary defects with extensive orbital involvement (at minimum complete orbital floor and rim absent) with titanium mesh sling and a layered fibula free flap...

PURPOSE: The aim of the present study was to compare the accuracy of two-dimensional (2D) and three-dimensional (3D) prediction methods. The hypothesis was that a 3D technique would give a more accurate outcome of the postoperative result. MATERIAL AND METHODS: Patients with severe class III occlusion were included and planed with both a 2D and 3D prediction technique. They were there after randomly subdivided into a control (2D) and test (3D) group and treated according to the technique randomized for...

Scissor bite is a rare form of malocclusion that is often accompanied by varying degrees of facial asymmetry. Correction and treatment of scissor bite in posterior teeth is a challenging job for an orthodontist. There are several treatment options for correction of scissor bite in posterior teeth but some have their own ill-effects on the dentition thus contributing further to the problem and some require patient compliance which compromises the outcome of the treatment. Therefore to overcome these drawbacks we have designed a new appliance to correct the molar scissor bite...

Congenital Ectropion Uveae (CEU) is a rare anomaly characterised by ectropion uveae, iris hypoplasia, iridotrabecular dysgenesis and glaucoma. Hyperplasia of the iris pigment epithelium and its apparent spread over the anterior surface of the iris is supposed to cause the classic ectropion uveae in CEU. Almost all patients develop open angle glaucoma due to angle dysgenesis, so they should be carefully examined periodically for its early detection. We hereby report a case of isolated unilateral CEU without any systemic association which is quite uncommon...

Unilateral condylar hyperplasia is an uncommon condition with unknown etiology which causes overdevelopment of condyle leading to facial asymmetry, mandibular deviation, malocclusion, and articulation dysfunction. Two Indian families with unilateral condylar hyperplasia are presented where the similar abnormality was also detected in one of their parents. The condylar hyperplasia in these two families indicates that mandibular condylar hyperplasia could be genetic in origin.

INTRODUCTION: We describe a case of intracerebral haemorrhage (ICH) following uncontrolled episodes of autonomic dysreflexia (AD) within 24 h of a minor urological procedure. CASE PRESENTATION: A 33-year-old active paraplegic patient T1 Association Impairment Scale A underwent an elective suprapubic catheter (SPC) placement for bladder management. The surgery was done under general anaesthesia and was uneventful. Four hours after surgery, he developed haematuria and multiple blood clots in the urine, which eventually caused blockage of the SPC and resulted in symptomatic AD...

BACKGROUND: Buccal fat is often used as a pedicled flap in cleft palate repairs to minimize scarring and fortify tenuous closures. Although many surgeons have adopted this technique, others have remained circumspect because of the concern for subsequent facial asymmetry. METHODS: Patients who underwent cleft palate repair using buccal fat pad flaps for closure between 2007 and 2015 were reviewed. Only patients with unilateral buccal fat pad flaps and three-dimensional photography were included...

PURPOSE: To develop a computer-based method for automating the repositioning of jaw segments in the skull during three-dimensional virtual treatment planning of orthognathic surgery. The method speeds up the planning phase of the orthognathic procedure, releasing surgeons from laborious and time-consuming tasks. MATERIALS AND METHODS: The method finds the optimal positions for the maxilla, mandibular body, and bony chin in the skull. Minimization of cephalometric differences between measured and standard values is considered...

PURPOSE: Maxillofacial deformities are always psychologically and physically distressing to the patients and is also challenging to the treating surgeons. The term Micrognathia means a "small jaw". True micrognathia, where the maxilla or the mandibular skeleton does not grow to the full size can be congenital or acquired. Distraction osteogenesis also called as callus distraction or callostasis or osteodistraction or distraction histogenesis is a biological process of regenerating newly formed bone and adjacent soft tissue by a gradual and controlled traction of surgically separated bone segments...
