Pedicled Tragal Chondral Flap for Interpositional Gap Arthroplasty in a TMJ Ankyloses.

Interpositional gap arthroplasty has shown good results; however, these techniques could be improved by taking into account the biological bases of the tissue used. Therefore, we suggest the pedicled tragal chondral flap as a safe, simple, and low-morbidity alternative.

Open Reduction of Condylar Fracture Through a Modified Endaural Approach.

Throughout history, several authors have extensively modified approaches to temporomandibular joint surgery to improve access, improve aesthetics, and decrease the risk of nerve damage. In this report, we propose the reduction of a medial condylar fracture through the modified endaural approach, being a safe approach for the facial nerve, effective, aesthetic, and simple to perform.

A Novel Method for Lengthening Iliac Crest Grafts for Mandibular Reconstruction.

The objective of this article is to propose a technique for mandibular reconstructions of up to 17 cm, in order to obtain anterior iliac crest grafts smaller than those required, and then lengthen them using corticotomies. This technique has been performed in 5 patients with an indication for reconstruction after partial mandibulectomy due to pathology. Reconstruction of the body of the mandible, including the angle in some cases, was performed using nonvascularized anterior iliac crest grafts.

Management of Bilateral Condylar Fractures in an Edentulous Patient with Atrophic Mandible Using CADCAM Technology.

Postoperative neurosensory impairment perception using ultrasonic BoneScalpel and conventional rotary instruments after bilateral split sagittal osteotomy.

Purpose: Although bilateral sagittal split osteotomy (BSSO) is the most widely used surgical technique for the correction of mandibular dentofacial anomalies, it is associated with lesion of inferior alveolar nerve (IAN) and unwanted neurosensory disorders. The aim of this study was to document the perception of changes in sensitivity and mean recovery time after BSSO, using an ultrasonic BoneScalpel versus the conventional rotary instruments.

Patients And Methods: This retrospective observational study included all patients with diagnosis of skeletal anomaly who underwent advancement or setback BSSO of less than 10 mL, using the ultrasonic osteotome or conventional rotary instruments.

Endoscopic Approach for Insertion of Custom-Designed Facial Implants.

The objective of this article is to describe the combination of virtual planning used to produce a custom-made facial implant, along with the minimally invasive endoscopic approach used to place it, for the reconstruction of the frontal bone. This management reduces the sequelae that occur with the traditional incisions while restoring the proper contour of facial surfaces at the same time.

The Morpho-Functional Three-Dimensional Analysis for Zygomatic Implants: A Clinical Tool With Surgical Implications.

Zygomatic implants (ZIs) have been used successfully for the rehabilitation of jaws with severe atrophy for the past 2 decades. The development of computed tomography, three-dimensional (3D) analysis software, and stereolithographic models has positively impacted the development of preoperative planning. This article describes the protocol developed by the Department of Oral and Maxillofacial Surgery of El Bosque University, Bogotá, Colombia, through 10 years of experience, for the installation of ZIs, covering from the times when the implants were placed through intraoperative guidance, until now, in which drilling guides developed by computer-aided design and computer-aided manufacturing are used, without neglecting in their design multiple factors that must be considered.

Active decompression and distraction sugosteogenesis for the treatment of calcifying odontogenic cyst.

The calcifying odontogenic cyst is as a benign, rare developmental odontogenic cyst with a wide range of histologic characteristics. It may present along with other odontogenic pathologies such as odontoma, ameloblastoma, adenomatoid odontogenic tumor, ameloblastic fibroma, and ameloblastic fibro-odontoma. Clinically, it can be an either intra- or extraosseous painless swelling that can produce cortical expansion.

Previously Reported Approach Now Used for Temporomandibular Joint Replacement.

Over time, different techniques have been described to obtain broad access to the temporomandibular joint (TMJ), in order to allow good visibility, minimizing post-operative complications at the same time. Most of these techniques have been very useful to perform joint replacement using custom made prostheses, varying in its extension, aesthetics and functional results. The aim of this study was to present the authors' experience using the Blair approach modified by Fernández in 2015, to replace failed TMJ prostheses, when distortion of the surgical reference points has occurred.

Is the Mandibular Growth Affected by Internal Rigid Fixation?: A Systematic Review.

Purpose: The purpose of this systematic review was to evaluate, in animal model-based studies, whether there are mandibular growth alterations, after open reduction and internal rigid fixation with titanium plates and screws.

Methods: A literature search was conducted using the MEDLINE, EMBASE, and LILACS databases, up to and including August 2015. Surgical reduction and internal rigid fixation (IRF) of induced fractures were compared to non-invasive procedures, in order to investigate if there were alterations in the mandibular growth patterns.

Conversion of Aneurysmal Bone Cyst into Fibrous Dysplasia: A Rare Pediatric Case Report.

Aneurysmal bone cyst (ABC) is an uncommon, non-neoplastic, expansive and erosive bone lesion. Considered as a pseudocyst due the lack of epithelial lining, the presence of giant cells and similarity to other lesions can make preoperative diagnosis difficult; biopsy findings must be co-related to complete clinical and radiological assessment. ABC's controversial etiopathogenesis and variable clinicopathological presentations have been widely described, but to date, there are just a few reports in literature describing the development of fibrous dysplasia (FD) from an ABC, and even less cases occurring in the jaws.
