Children with Prader-Willi Syndrome (PWS) may present with a malocclusion and have a high propensity of developing obstructive sleep apnea (OSA). Obstructive sleep apnea is associated with short- and long-term adverse effects that negatively impact children with PWS. A case of a 15-year-old male with PWS, OSA, and a debilitating malocclusion is presented who underwent a combination of Le Fort 1 osteotomy, genioplasty, and tongue reduction to successfully treat his OSA and malocclusion. In select cases, orthognathic correction and other surgical therapies should be considered in patients with PWS...

The demand for facial feminization is increasing in transsexual patients. Masculine foreheads present extensive supraorbital bossing with a more acute glabellar angle, whereas female foreheads show softer features. The aim of this article is to describe our surgical technique for fronto-orbital feminization. The mask-lift technique is an upper face-lift. It provides rejuvenation by correcting collapsed features, and fronto-orbital feminization through burring of orbital rims and lateral canthopexies. Depending on the size of the frontal sinus and the thickness of its anterior wall, frontal remodeling is achieved using simple burring or by means of the eggshell technique...

AIM: To compare the esthetic perception of different observer groups of 14 photos of two patients with Class II, division 1 malocclusion with severe mandibular retrusion. MATERIALS AND METHODS: A sample of 441 participants, of which 191 were laypeople, was obtained through a snowball sampling method. Fourteen photos of two children with Class II, division 1 malocclusion with severe mandibular retrusion were used, before and after orthodontic treatment (OT), with advance genioplasty simulation...

Aims: The aim of this study was to evaluate cephalometrically the stability of hard tissues and soft tissue changes of advancement genioplasty 2 years after surgery. Methods: A prospective study was conducted which comprised of 25 patients, who underwent advancement genioplasty alone with no other orthognathic surgical procedures. Immediate pre-operative, 6 months postoperative, and 2 years postoperative lateral cephalograms were compiled and assessed. Results: The mean surgical advancement planned was around 8 mm...

PURPOSE: The purpose of this study was to document the malocclusion and facial dysmorphology in patients with primary maxillary deficiency (PMD) and chronic obstructive nasal breathing before treatment and the outcomes after bimaxillary orthognathic, genioplasty, and intranasal surgery. MATERIALS AND METHODS: A retrospective cohort study of patients with PMD undergoing bimaxillary orthognathic, chin, and intranasal surgery was implemented. The predictor variables were grouped into demographic, anatomic, operative, and longitudinal follow-up categories...

Hallermann-Streiff syndrome (HSS) is a rare congenital disorder that mainly affects head and face development. We described the different patterns of the disease throughout the whole growth period and provided innovative treatment steps. Indeed, early genioplasty and dental implantation before growth completion were performed. These steps allowed to improve facial growth and to provide orthodontic anchorage, respectively. Complementary orthognathic surgery achieved satisfactory occlusion and refined aesthetics...

PURPOSE: Recent clinical studies have shown piezotomes might establish the new "state of the art" for osteotomies in maxillofacial surgery. The author hypothesized genioplasty surgery with piezotomes might decrease postsurgical morbidity and increase overall patient satisfaction compared with genioplasty with traditional instruments. MATERIALS AND METHODS: The author implemented a randomized clinical trial. The sample was composed of patients undergoing reductive genioplasty...

BACKGROUND: Recently, the mandibular body and chin shape are known to be important issue as well as the mandibular angle. The authors have performed the one-piece mandibuloplasty from the mandibular angle to the most anterior part of chin to achieve the change of the whole mandibular shape as a one-piece. METHODS: All of 14 patients who complaint prominent mandibular angle and chin were randomly allocated into 2 groups. Group I (n = 7) was treated with conventional mandibuloplasty with narrowing genioplasty and Group II (n = 7) was treated with one-piece mandibuloplasty...

Melnick-Needles syndrome (MNS) is a rare congenital X-linked dominant skeletal dysplasia, characterized by exophthalmos, a prominent forehead, and mandibular hypoplasia and retrognathism. Dental features may include anodontia, hypodontia, or oligodontia. Increased collagen content, unpredictable collagen synthesis, and abnormal bony architecture have raised concerns regarding bone splitting intraoperatively and bone healing postoperatively. This report describes the cases of two sisters with MNS, who successfully underwent orthognathic surgery consisting of bilateral mandibular ramus osteotomies combined with advancement genioplasty and iliac crest bone grafting, to correct the classical MNS facial deformity of mandibular retrognathia...

BACKGROUND: Mandibular angle ostectomy is one of the most common surgical procedures for facial contouring in Asian women. However, some patients complain about mandibular angle hypertrophy recurrence after surgery. The present study evaluated volumetric change of the mandible after angle ostectomy and outer cortex grinding. METHODS: Twenty-four patients who underwent bilateral mandibular angle ostectomy and outer cortex grinding from 2013 to 2016 were enrolled...

INTRODUCTION: The purpose of this study was to retrospectively evaluate the difference between the planned and the actual movements of the jaws, using three-dimensional (3D) software for PC-assisted orthognathic surgery, to establish the accuracy of the procedure. MATERIAL AND METHODS: A retrospective study was performed with 49 patients who had undergone PC-guided bimaxillary surgery. The accuracy of the protocol was determined by comparing planned movements of the jaws with the actual surgical movements, analysing frontal and lateral cephalometries...

INTRODUCTION: As well as the chin is an important esthetic unit of the facial structure, it is also the region having a key role in the appearance of the face. Correction of cosmetic and functional deformities that may occur in this region because of serious hypoplasia (microgenia) is performed by chin augmentation. Chin augmentation is most frequently performed via implant or osseous genioplasty in the literature. Both 2 techniques have their own advantages and disadvantages. In the literature, various studies comparing these 2 techniques and their long-term results are present, but in some severe microgenia cases, these techniques can be insufficient only for augmentation...

Chin augmentation is commonly practiced, whether in microgenia treatment, in cases of orthognathic or cosmetic surgery. Located at the crossroads of many specialties, the technique choice still differs according to the surgeon specialiy. A large number of publications on the subject are available. A comparaison between different surgical methods is therefore possible concerning their indications and their complication. The purpose of this study was to carry out a literature review, with updating knowledge, as well as a synthesis indication regarding aesthetic osseous and alloplastic genioplasty...

The chin may be concerned by morphological abnormalities in its various dimensions. Classical genioplasty techniques can be used to correct these but have some disadvantages. The "chin wing", described by Triaca, is a technique of genioplasty extended to the mandibular angles, considering the mandibular basilar border as an anatomical unit, thus achieving a better harmonious functional and aesthetic result. The preoperative assessment included a mandibular Cone Beam to evaluate the position of the inferior alveolar nerve...

Objectives: Mandibular angle reduction or reduction genioplasty is a routine well-known facial contouring surgery that reduces the width of the lower face resulting in an oval shaped face. During the intraoral resection of the mandibular angle or chin using an oscillating saw, unexpected peripheral nerve damage including inferior alveolar nerve (IAN) damage could occur. This study analyzed cases of damaged IANs during facial contouring surgery, and asked what the basic standard of care in these medical litigation-involved cases should be...
