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...

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...

Genioglossus muscle advancement (GMA) was reported in 1993 as an option for the surgical treatment of obstructive sleep apnoea syndrome (OSAS), in the context of phase I of the Stanford University (Powell-Riley) protocol. The rationale for this technique is the placement of tension on the base of the tongue, thus preventing the tongue from falling back into the posterior airway space. However, in retrognathic patients undergoing phase I of the Stanford University protocol, an additional genioplasty will provide a better aesthetic outcome...

The aim of this study was to present a case series of the orthognathic treatment of facial asymmetry due to temporomandibular joint (TMJ) ankylosis and to characterize the current treatment modalities through a literature review. Four patients who presented with facial asymmetry due to TMJ ankylosis between 2010 and 2014 were included in this study. TMJ ankylosis was surgically treated before bimaxillary surgery with advancement genioplasty in some of the cases. In 2 cases, 3-dimensional (3D) models were used for diagnosis and treatment planning, as 3D models are very important tools for planning surgical maneuvers...

INTRODUCTION: Cutting and drilling guides manufactured using computer-aided design/computer-aided manufacturing (CAD/CAM) technologies have attracted increasing interest in orthognathic surgery, particularly in complex cases. The development of these guides requires virtual surgery planning and three-dimensional modelling before they can be printed in titanium, polyamide or resin. We report the use of a personalized titanium device to assist bilateral sagittal split osteotomy (BSSO) with or without genioplasty combined with individual implants for repositioning and fixation...

REVIEW
Armando Retana
Facial cosmetic surgery techniques are constantly updated to meet the expectations of patients who demand less invasive procedures and less recovery time. Current trends in lower eyelid surgery call for periorbital fat repositioning instead of excision of fat. Controversies still exist in chin augmentations regarding osseous genioplasty versus alloplastic chin implant. The benefits, disadvantages, and considerations of these procedures are discussed.
