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...

Orthodontic camouflage provides an alternative treatment for angle III malocclusion since patients with limited economic resources cannot opt for orthognathic surgery, it being clear that correction will be achieved at the dental level and not at the bone complex. OBJECTIVE: To determine an alternative treatment for patients who do not have the possibility of having orthognathic surgery. CLINICAL CASE: A 13-year-old female patient, dolico facial biotype with slightly concave profile, with Class III Skeletal by mandibular prognathism, anterior crossbite, anterior diastema, and large mandibular body, molar class, and canine III...

INTRODUCTION: Correction of severe malocclusions with skeletal discrepancies requires orthodontic treatment in combination with orthognathic surgery. Even though conventional orthognathic surgery (COS) is a common and well-accepted approach its influence on the signs and symptoms of temporomandibular disorders (TMDs) is still debated. Recently with the introduction of surgery first approach, a different timing for the management of dentoskeletal imbalances has been proposed. The present study is aimed at assessing the relationship between surgery first approach and temporomandibular joint (TMJ) disorders...

The relationship of the maxillary incisor to forehead position and angulation may be a predictor for the esthetic antero-posterior maxillary position in orthognathic surgery, but this has not been fully explored in the existing literature. Additionally, this analysis requires a lateral smiling photograph, which is not typically included in orthodontic/orthognathic records. This is a bidirectional study of Caucasian orthodontic patients with malocclusions correctable with nonsurgical and nonextraction treatment...

The aim of this study was to analyze the presence of complications related to orthognathic surgery performed by surgeons in train. A retrospective study was conducted between 2005 and 2014, analyzing the clinical records of patients treated in the authors' Department. Patients who underwent orthognathic surgery were included, under a bidimensional analysis and with the conventional orthosurgical sequence; intraoperative complications were identified, such as the occurrence of a bad split, bleeding, tissue injury, among others and postoperative variables such as impaired sensation, infection, and alterations in the osteosynthesis systems...

Postoperative nausea and vomiting (PONV) is one of the most unpleasant experiences after surgery. It reduces patient satisfaction and also increases hospital costs due to longer hospitalizations. The aim of this prospective study was to determine whether orthognathic surgery is associated with more PONV than less invasive maxillofacial surgery. Three hundred and eight patients aged 8-87 years who underwent maxillofacial surgery were included. The PONV score, based on the Apfel score, was calculated preoperatively...

REVIEW
Hyun Seok, Seong-Gon Kim
Botulinum toxin (BTX) is a neurotoxin, and its injection in masticatory muscles induces muscle weakness and paralysis. This paralytic effect of BTX induces growth retardation of the maxillofacial bones, changes in dental eruption and occlusion state, and facial asymmetry. Using masticatory muscle paralysis and its effect via BTX, BTX can be used for the correction of malocclusion after orthognathic surgery and mandible fracture. The paralysis of specific masticatory muscles by BTX injection reduces the tensional force to the mandible and prevents relapse and changes in dental occlusion...

The authors aimed to test the hypothesis that in orthognathic surgery the maxilla could be repositioned using spatial distances from Glabella to 3 maxillary dental landmarks as references. An asymmetric skeletal Class 3 malocclusion patient was involved and bimaxillary orthognathic surgery was planned. Virtual surgery was simulated and spatial distances from Glabella to midpoint of the upper dentition (U0) and bilateral medial-buccal cusp of the first molar (6L and 6R) were measured. These distances were used as the repositioning references and were imported intraoperatively into a digital caliper after the maxilla was mobilized, the repositioning of maxilla was manipulated till all the true spatial distances reached the references...

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...
