RESUMO
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.

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.

Several techniques have been proposed for the management of perforation of or severe damage to the temporomandibular joint disc, with a wide range of success rates reported. We describe a new method using a pedicled sliding flap of the tragal cartilage.

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. RESULTS: Of a total of 624 potentially relevant papers identified through the searching process, five were eligible for inclusion. Three studies using 3-month old New Zealand white rabbits induced fractures of mandibular body or symphysis and internal fixation with titanium microplates and screws, whereas two were based on 6-month old goats with condylar fracture. None of the studies showed statistically significant difference between experimental and control groups. CONCLUSION: As literature regarding this subject is scarce, and the included studies show low level of evidence, it is not possible to conclude that open reduction and internal rigid fixation with titanium plates and screws cause significant growing alteration of the mandible.
RESUMO
OBJECTIVE: The aim of this study is to present our experience with a modification of the Blair approach to the parotid area, by means of a modified endaural component, which provides both excellent exposure and optimal functional and esthetic results, mainly over the preauricular area. PATIENTS AND METHODS: A retrospective case series study was performed. It included surgical cases of patients who were operated on the parotid region in which the mentioned approach was indicated. The information was collected from the database available at the Universidad El Bosque Oral and Maxillofacial Surgery Department in Bogota, Colombia from 2008 to 2013. RESULTS: The sample consisted of 12 patients, with ages ranging from 23 to 56 years and a mean age of 38 years. A total of 8 patients were women and 4 patients were men. Parotid pathologies included salivary gland tumor (10 patients) and cranial base tumor (2 patients). Procedures executed were: superficial lobe and total parotidectomy resection, pharynx extended and cranial base tumor resections. CONCLUSIONS: This investigation presents our experience with a modified approach to the parotid region. This approach gives an extended and safe exposure to the region with excellent cosmetic outcomes.

We present a modification of the classic lateral canthal approach by means of which the anatomy of the lateral palpebral edges will remain unscathed, with the incision beginning 2 mm lateral to the external canthus. We have used this technique in 76 patients at 3 major trauma centers in Bogota, Colombia, from January 2006 to January 2012. The approach provided excellent access to the frontozygomatic area, lateral wall of the orbit, and malar body. This method avoids important anatomic structures and offers outstanding cosmetic results, especially in adult patients.
