Oral Presentation
the oral cavity. Clinically ameloblastoma presents solid or cystic form and histologically shows different pattern. Radiologically they appear as unicystic, multicystic and extraosseous type. Usual treatment methods consist of enucleation, curettage, dredging and excision of tumor followed by immediate and delayed reconstruction. Ameloblastoma has strong tendency to recurrence. Objectives: The purpose of this paper is to assist surgeons to develop rational approach to the surgical management of ameloblastoma through evaluation and assessment of individual case. Methods: The study was done at Dhaka dental College and Hospital, Dhaka, Bangladesh from 2004 to 2012. Total 125 cases were evaluated in this study. Findings: Small ameloblastomas were enucleated and cases with massive involvement and bone destruction were treated by jaw resection and reconstruction. Mostly female and children cases with small to moderate sized tumors were treated with dredging method which revealed excellent outcome. Conclusion: Tumor site, size, sex and age of the patient and also clinical, histologic type guide to selecting the method of surgical treatment.
is to present an easy and versatile method for the treatment of Temporomandibular Joint ankylosis and to decrease re-ankylosis. Material and method: This paper is a study based on pre, intra and post op evaluation of fifteen patients who underwent surgical release of Unilateral Temporomandibular Joint Ankylosis followed by temporalis fascia flap interposition arthroplasty, between 2008 and 2014. The follow-up time was 1–5 years. Results: Re-ankylosis did not occur in any of the patients, and all of the patients had satisfactory mouth opening. Conclusion: Surgical treatment of TMJ ankylosis with interposition of the temporalis fascia is an effective and easy procedure for prevention of re-ankylosis. The autogenous nature and close proximity to the joint are the main advantages of the temporalis fascia flap when compared with other interpositional materials.

Background: The current gold standard for the reconstruction of critical-sized maxillofacial defects is the transfer of vascularized bone flaps. These flaps cause donor site morbidity and compromise masticatory function. Bone engineering presents a promising alternative, however it has failed to make a significant clinical translation, largely due to a lack of robust vascularization strategies. Objectives: To design a novel surgical technique to optimize vascularization of a custom designed, 3D printed bone tissue engineering scaffold by building on the current arteriovenous (AV) loop model, and investigating the efficacy of inducing collateral vessels. Methods: In this study, four models (Extrinsic Control, Angiogenesis, Arteriogenesis and AV loop) were investigated to identify the optimal strategy to vascularize bioceramic scaffolds. The monetite scaffolds were manufactured with either a constant luminal diameter or in a tapering fashion. Following in vivo periods of 2- and 4-weeks, tissue specimens were analyzed histologically to quantify the density of blood vessels, and radiographically to determine the degree of graft resorption. Findings: At both the 2- and 4-week time point, the arteriogenesis model displayed a greater density of blood vessels. Furthermore, the arteriogenesis model had the highest rate of graft resorption, an indicator of total mass transfer that can be correlated to the degree of scaffold vascularization. Conclusion: Based on the results of our study, the ideal strategy to vascularize large scaffolds must induce both arteriogenesis and angiogenesis. Furthermore, we discovered that the alteration of scaffold structure can manipulate vascular development and potentially enhance clinically relevant bone engineering.
High cervical versus preauricular anteroparotid transmasseteric approaches for condylar fractures repair A. Mahrous Plastic and Maxillofacial Surgery Department, El Minia, Egypt Background: The transmasseteric approaches has been considered a well established approaches for condylar fracture repair. They may be accessed through a preauricular anteroparotid incision, a high cervical incision or a retromandibular incision. Aim: The aim of this study was to compare the high cervical transmasseteric approach and the preauricular anteroparotid one as regards the accessibility, the rate of complications and the final outcome. Patients: Twenty-four patients had malocclusion due to a unilateral low subcondylar fractures either alone or associated with other fractures were classified into two groups. Group (A) included 12 patients accessed through the high cervical transmasseteric approach. The second group (B) included 12 patients accessed through the preauricular anteroparotid transmasseteric one. Results: The high cervical approach was found to have a better accessibility, a low complication rate especially those related to the facial nerve and a better outcome. Conclusion: When a transmasseteric approach is chosen to repair a fracture condyle, it is better to utilize the high cervical rather than the preauricular anteroparotid one. http://dx.doi.org/10.1016/j.ijom.2015.08.690
