Orthognatic surgery

Guilherme Janson, Olga Benário Vieira Maranhão
Skeletal Class III malocclusions are ideally treated with orthodontic-surgical approaches. However, if there are no significant soft tissue implications and the patient does not want to undergo orthognatic surgery, other treatment options may be considered. The current case report describes a compensatory alternative for Class III malocclusion treatment, by means of mandibular canine extractions. This treatment alternative provided facial profile and occlusal improvement, which remains stable seven years posttreatment...

A major objective of orthognatic surgery is the aesthetic outcome. Treatments only correcting for dentoskeletal deformities are not sufficient for optimal facial results because undesirable soft tissue changes may accompany skeletal manipulations. The primary objective of this study was to investigate alar base width (ABW) changes a minimum of 6 months following surgically-assisted rapid palatal expansion (SARPE). The following electronic databases and citation indices were searched: PubMed, Cochrane Library, Scopus, Web of Science, Embase, and Virtual Health Library...

Cardiovascular complications, in particular perioperative myocardial infarctions, are central contributors to morbidity and mortality after non-cardiac surgery. We present a case of a 41-year-old male, smoker and dyslipidemic, who underwent bimaxillary orthognathic jaw surgery with the development of an acute coronary syndrome in the immediate postoperative period. We managed to early diagnose the myocardial infarction and promptly performed a percutaneous transluminal coronary angioplasty, resulting in a positive outcome...

BACKGROUND: Several correlations between morphological and/or positional alterations of the jaws and respiratory functional impairments have been reported. Nasal airway obstruction represents a critical issue with no clearly defined gold standard as for its measurement. Rhinomanometry was adopted by multiple Authors to evaluate whether patients with malocclusion developed respiratory functional changes after an orthodontic-surgical treatment. However, there are contrasting findings in the literature regarding the possibility of improving the respiratory function by means of surgically-assisted rapid palatal expansion (SARPE) or bimaxillary repositioning of the bony bases...

Maxillo-mandibular asymmetry has numerous aetiologies: congenital, traumatic, iatrogenic and post-oncologic. Patients with congenital dentofacial malformations are generally submitted to orthognathic surgery and/or additional procedures (genioplasty, alloplastic implants) with satisfactory results. However, despite achieving skeletal symmetry, noticeable facial asymmetry may persist.This study was performed in 45 patients (29 women and 16 men) operated between December 2012 and June 2014. All patients were affected by maxilla-mandibular asymmetry and underwent orthognatic surgery for hard tissue correction of the deformity...

The bilateral sagittal osteotomy (BSSO) is a widely used surgical technique within orthognatic surgery. The specific osteotomy design may vary from clinic to clinic. The best position of the bone cuts in a BSSO continues to be a point of discussion and probably differs from patient to patient. In addition, standardisation in, for example, research may be desirable. Pre-operative planning using a drilling template in order to position the planned individual saw cuts during BSSO can be of value. To achieve this goal, a pre-operative 3D printed biocompatible drilling template was manufactured for 1 patient on the basis of pre-operative planning...

The aim of this case report is to give comprehensive information on the clinical use of computerized axiography (CA) in the evaluation of temporomandibular joint (TMJ) mobility in a patient who undergoes orthognatic surgery. A 20-year-old female patient with class III skeletal anomaly and who underwent orthognatic surgery is presented. Pre- and postsurgical CA recordings for the patient are compared in order to evaluate the functional modifications that appear. The CA is a functional investigation of the TMJ and records the border movements of the mandible: protrusion, lateral movements and open/close...

Maxillo-mandibular advancement MMA is considered an efficacious treatment for patients affected by severe obstructive sleep apnoea syndrome (OSAS). Even though OSAS improvement is the main goal of MMA, excessive maxillo-mandibular protrusion should be avoided to guarantee pleasant postoperative facial aesthetics. In order to attain such a result, the amount of MMA should be planned preoperatively by both aesthetic and cephalometric analyses. Steiner and Delaire cephalometric analyses are commonly used in the preoperative planning of orthognatic surgery for dentofacial deformities, however controversies still exist about the basis and postoperative aesthetic results of such cephalometric analyses in OSAS patients candidate for MMA...

Skeletal anterior open bite (AOB) or apertognathism is characterized by the absence of contact of the anterior teeth and affects articulation parameters, chewing, biting and voice quality. The treatment of AOB consists of orthognatic surgical procedures. The aim of this study was to evaluate the effects of treatment on voice quality, articulation and nasality in speech with respect to skeletal changes. The study was prospective; 15 patients with AOB were evaluated before and after surgery. Lateral cephalometric x-ray parameters (facial angle, interincisal distance, Wits appraisal) were measured to determine skeletal changes...

An adequate orthodontic preparation is a key to success of every orthognatic surgery. Therefore, the detection and the correction of the existing dentoalveolar compensation tend to favor the correction of the skeletal defects. The pre-surgical orthodontic goals have to be defined at the beginning of the treatment, thus, not always achieving a complete leveling of the arches, nor a final space closure and ideal intercuspation. The orthodontic preparation aims to guide the surgical skeletal displacements. Many dentoalveolar compensations can be identified as specific to different types of malocclusion...

Complete restoration of facial asymmetry is always difficult to achieve. Facial asymmetry due to growth disturbances of the jaws almost requires orthognathic surgical correction, followed, in many cases, by soft tissue corrections. Mandibular hypoplasia is the earliest skeletal manifestation of Hemifacial microsomy and the clinical defect becomes worse with the time, due to asymmetric growth and secondary midface deformity accompanying. Despite correction of the occlusal plane, facial asymmetry can persist if the mandibular body differs in height...

A woman undergoing orthodontic treatment presented with recession and reduced keratinized gingiva on teeth 31 and 41. The patient declined creation of a donor site for conventional autogenous connective soft tissue grafting and opted for an acellular dermal matrix soft tissue substitute for root coverage. Orthodontic treatment followed, and the patient returned for orthognatic surgery after 12 years. Long-term follow up revealed that root coverage remained stable over time and creeping attachment on both teeth was observed...

BACKGROUND: Trismus-Pseudocamptodactyly Syndrome (TPS) is a rare autosomal syndrome characterised by the inability to open the mouth fully, pseudocamptodactyly, short stature and foot deformities. The maxillofacial feature entails hyperplasia of the coronoid processes which mechanically interfere with the zygomatic processes during mouth opening. CASE REPORT: A 22-year-old girl affected by a severe form of TPS was followed from the age of three years. Bone reossification was observed after two coronoidotomies of both hyperplasic coronoid processes...
