PURPOSE: Nearly 10% of patients remain dissatisfied after orthognathic surgery, largely because of psychoeducational or psychosocial factors. The purpose of this study was to evaluate the feasibility and acceptability of a psychoeducationally based group intervention to improve preoperative preparation of orthognathic surgical patients and their caregivers. MATERIALS AND METHODS: The intervention consisted of 2 group sessions, with each session lasting 2 hours...

Kasper Stokbro, Torben Thygesen
PURPOSE: In orthognathic surgery, the repeatability of 3-dimensional (3D) measurements is limited by the need for manual reidentification of reference points, which can incorporate errors greater than 1 mm for every 4 repeated measurements. This report describes a semiautomatic approach to decrease the manual reidentification error. This study evaluated the repeatability of surgical outcome measurements using the semiautomatic approach. Furthermore, a step-by-step guide is provided to enable researchers and clinicians to perform the 3D analysis by themselves...

PURPOSE: The purpose of this randomized trial was to measure the effect of intravenously administered tranexamic acid (TXA) on intraoperative blood loss (IOB) in patients undergoing bimaxillary orthognathic surgery (OS). MATERIALS AND METHODS: The authors designed and implemented a double-blinded placebo-controlled trial composed of patients eligible for OS at the Hospital of South West Denmark (Esbjerg, Denmark) from August 2014 through September 2016. The primary predictor variable was a single intravenous dose of TXA 1 g administered preoperatively or an equivalent saline placebo...

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...

REVIEW
Luis Delgado, Avanti Verma, Teresa M O, Stuart Super
Vascular malformations affect the craniofacial skeleton in many ways, depending on the type of the lesion and its location. The lesions may exert a mass effect and cause thinning or thickening of the bone or cause expansion from direct bony infiltration. Orthognathic surgery can be used to correct any malocclusion or open bite deformities after the soft tissues are addressed.

OBJECTIVE: This study evaluated the relationship between follow-up temporomandibular joint positional change and mandibular stability among patients who had orthognathic and orthodontic treatment for a skeletal Class II malocclusion. METHODS: Thirty-seven patients who underwent 2-jaw surgery (Le Fort I osteotomy, bilateral sagittal split ramus osteotomy and genioplasty with rigid internal fixation) were included with an average follow-up length of 8.10 ± 2.06 years...

Patients with ectodermal dysplasia have abnormalities of 2 or more structures that originate from the ectoderm. The oral manifestations often include the congenital absence of teeth and malformed teeth. This clinical report describes the interdisciplinary care from childhood through the definitive dental rehabilitation completed at skeletal maturation to replace the missing teeth in a patient with ectodermal dysplasia. Treatment began at 9 years of age with an implant-assisted mandibular overdenture to improve function and replace the missing mandibular teeth...

Distraction osteogenesis has been a paradigm shift in the field of orthognathic surgery. Majority of the published cases are those of syndromic patients that have been managed using varying treatment protocols. This communication describes a patient of 18-year-old male diagnosed with skeletal Class II malocclusion due to mandibular retognathism. The patient was taken up for mandibular corpus distraction of 10 mm. By this approach the patient was benefitted with good esthetic result and functional occlusion...

BACKGROUND AND AIM: Postoperative pain is well known and usually disturbing complication of surgery. Inflammation plays an important role in the development and progression of postoperative pain. We aimed to investigate possible relationship between preoperatively measured neutrophil-lymphocyte ratio (NLR) - as an inflammation marker - and postoperative analgesic demand in patients underwent orthognathic surgery. MATERIALS AND METHODS: We retrospectively investigated medical and anesthesia records of 177 patients underwent orthognathic surgery...

In this review, we aimed to depict the clinical, radiological, and genetic features of cleidocranial dysplasia (CCD) and to suggest management guidelines, based on our experience of 8 cases, with an emphasis given to dental complications.The most common craniofacial features of CCD that stand out are a patency of the anterior fontanelle, an inverted pear-shaped calvaria, a hypertelorism, a general midface retrusion, and a mandible prognathism, associated with an excessive mobility of the shoulders, a short stature, and teeth abnormalities such as supernumerary teeth and failure of eruption, in particular...

OBJECTIVE: To evaluate vertical stability after various orthognathic surgical treatment plans for skeletal class Ⅲ malocclusion with anterior openbite. METHODS: A retrospective multicenter cohort study was conducted to investigate vertical stability after various orthognathic surgical treatment plans for skeletal class Ⅲ malocclusion with anterior openbite. From 2010-2016, 122 patients from two domestic stomatological hospitals were included in our study. Patients were divided into four groups according to their treatment plans, namely, bilateral sagittal split ramus osteotomy (BSSRO), intraoral vertical ramus osteotomy (IVRO), BSSRO+Le Fort Ⅰ, and IVRO+Le Fort Ⅰ...

The aim of this study was to evaluate the effect of counterclockwise (CCW) rotation and maxillomandibular advancement (MMA) on the upper airway space using three-dimensional images. An electronic search was performed in the PubMed, Cochrane Library, Scopus, Virtual Health Library, Web of Science, and OpenGrey databases (end date July 2016); a hand-search of primary study reference lists was also conducted. The inclusion criteria encompassed computed tomography evaluations of the upper airway spaces of adult patients undergoing orthognathic surgery with CCW rotation and MMA...

INTRODUCTION: This pilot study had as main objective to test the reliability of a new method to evaluate orthognathic surgery outcomes and also, to understand the effect of hard tissue changes on soft tissue displacement. METHODS: The sample consisted of eight patients that underwent bimaxillary advancement and had CBCT at two time points (before surgery and 6-8 months follow-up). Voxel-based cranial base superimposition was used to register the scans. A different technique of iterative closest point (ICP) was used to measure and correlate the changes...
