Surgical management in epithelial ovarian cancer (EOC) has a significant impact in overall survival (OS) and progression free survival (PFS). Brazilian Society of Surgical Oncology (BSSO) supported a taskforce with experts for consensus: experienced and specialized trained surgeons, in cancer centers, provide the best EOC surgery. Laparoscopic and/or radiological staging prognosticate the possibility of complete cytoreduction (CC0) and help to reduce unnecessary laparotomies. Surgical techniques were reviewed...

Our aim was to assess patients' perception of paraesthesia of the lower lip after bilateral sagittal split osteotomy (BSSO) at a district general hospital. Patients who had BSSO between August 2013 and August 2014 (n=46) were asked to score their perception of numbness between 0-10 (0=normal sensation. 10=complete loss of sensation/total numbness) one day postoperatively and then weekly for seven weeks, and at three months, 6 months, and one year. Data was collected on score sheets and by regular contact by telephone...

Bilateral sagittal split osteotomy (BSSO) is a widely-performed procedure in orthognathic surgery for the correction of dentofacial deformity. Condylar positioning is a critical step during BSSO to maximize functional and morphological results. The unsuitable positioning of condyles represents one of the causative mechanisms that may induce temporomandibular joint noxious effects after BSSO. Repositioning devices can assist surgeons in maintaining the preoperative condylar position; however, empirical repositioning methods based on experience gained are still commonly used...

Bilateral sagittal split osteotomy (BSSO) is a surgical technique to correct hypoplasia, hyperplasia or asymmetry of the mandible. The risk of complications associated with BSSO with splitter and separators, the so-called splitter-separator technique, and the predictability of this technique were analysed. The average incidence of complications associated with classic BSSO techniques was determined by a review of the literature. With classic techniques, a bad split occurred in 2.3% of the operated sides, removal of osteosynthesis material on account of complaints in 11...

INTRODUCTION: The main challenge during the osteosynthesis of a bilateral sagittal split osteotomy (BSSO) is to take into account the correct position of the condyle. Adjustable plates can be used to fine-tune the final occlusion without changing the osteosynthesis. A new type of adjustable plate is presented in this article. The aim is to assess the mechanical reliability of this system during the surgery and during the healing period, thanks to a preliminary prospective on 15 consecutive cases...

In some units, lower wisdom teeth are extracted in a separate procedure before bilateral sagittal split osteotomy (BSSO), whereas in others they are removed at the time of the osteotomy. We identified 57 patients who had BSSO at Salisbury Hospital between October 2013 and September 2015, 40 of whom had their wisdom teeth extracted at the same time. The remaining 17 did not have wisdom teeth. Patients who have these teeth extracted as a separate procedure require at least one day off work, which can result in a loss of earnings...

INTRODUCTION: Cutting and drilling guides manufactured using computer-aided design/computer-aided manufacturing (CAD/CAM) technologies have attracted increasing interest in orthognathic surgery, particularly in complex cases. The development of these guides requires virtual surgery planning and three-dimensional modelling before they can be printed in titanium, polyamide or resin. We report the use of a personalized titanium device to assist bilateral sagittal split osteotomy (BSSO) with or without genioplasty combined with individual implants for repositioning and fixation...

BACKGROUND: The purpose of orthognathic surgery is to correct facial deformity and dental malocclusion and to obtain normal orofacial function. However, there are controversies of whether orthognathic surgery might have any negative influence on temporomandibular (TM) joint. The purpose of this study was to evaluate the influence of orthognathic surgery on articular disc position and temporomandibular joint symptoms of skeletal CI II patients by means of magnetic resonance imaging. MATERIAL AND METHODS: For this purpose, fifteen patients with skeletal CI II malocclusion, aged 19-32 years (mean 23 years), 10 women and 5 men, from the Isfahan Department of Oral and Maxillofacial Surgery were studied...
