Types of Intermaxillary Fixation and Their Interaction With Palatine Fracture Reduction.

Purpose: To compare 3 types of intermaxillary fixation (IMF) and their behavior when subjected to tension forces in 3 study models with a palatine fracture feature.

Materials And Methods: An experimental study of 3 identical acrylic models was performed. All had the same palatine fracture pattern on the maxillary midline.

Reconstruction of medial orbital wall using a retrocaruncular approach.

The purpose of the study was to analyze and describe the retrocaruncular approach to access medial orbital wall. A retrospective analysis was performed in patients referred for the treatment of orbital fractures between January 1st 2011 and July 31st 2017. The study included patients over 18 years old with isolated fractures of the medial orbital wall or combined with the orbital floor who underwent a transconjunctival approach with retrocaruncular extension and lateral canthotomy, and with a minimum follow-up of 6 months.

Correlation Between the Posterior Mandibular Width and the Lingual Gap Caused by Symphyseal Fractures Using a Virtual Model.

Purpose: The objective was to determine the dimensional impact, on the occlusal and articular level, of the gap produced in the lingual plate from symphyseal fractures, correlated with the dimensional change in the posterior mandibular width.

Materials And Methods: We performed an observational experimental study based on 30 computed tomography scans of patients treated by the Maxillofacial Surgery Service, Hospital Clínico Mutual de Seguridad, Santiago, Chile, between 2012 and 2016. The inclusion criteria were jaws without evidence of fractures or pathology, with an absence of orthodontic appliances, and with complete dentition to the first mandibular molar.

C-arm as intraoperative control in reduction of isolated zygomatic arch fractures: a randomized clinical trial.

Purpose: Isolated zygomatic arch fractures (IZAFs) are habitually reduced at a distance, via a temporal approach. Open reductions are not recommended due to the associated morbidity and complications. However, performing closed reductions makes it difficult to determine whether it was done satisfactorily.

Use of onabotulinumtoxinA in post-traumatic oromandibular dystonia.

Purpose: Post-traumatic oromandibular dystonia (PTOD) is a disorder whose symptoms can include bruxism, muscle pain, and involuntary muscle contraction, among others. The use of onabotulinumtoxinA (ObT-A) is helpful in controlling the symptoms of patients with PTOD. The aim of this study was to evaluate the use of ObT-A in the treatment of PTOD.
