PURPOSE: Augmented reality-based constructive jaw surgery has been facing various limitations such as noise in real-time images, the navigational error of implants and jaw, image overlay error, and occlusion handling which have limited the implementation of augmented reality (AR) in corrective jaw surgery. This research aimed to improve the navigational accuracy, through noise and occlusion removal, during positioning of an implant in relation to the jaw bone to be cut or drilled. METHOD: The proposed system consists of a weighting-based de-noising filter and depth mapping-based occlusion removal for removing any occluded object such as surgical tools, the surgeon's body parts, and blood...

PURPOSE: Unilateral or bilateral ankylosis can lead to severe micrognathia and facial deformity that requires multiple, often, staged surgical corrections. To date, there is no ideal treatment modality that satisfactorily corrects the complex anatomy, restores the ramal height, and corrects the micrognathia and microgenia. Distraction osteogenesis has been acclaimed as a successful modality for the treatment of such deformities. It is a cost-effective approach with low morbidity and less relapse thus providing better functional and esthetic outcomes...

PURPOSE: Fluorescence-guided surgery has been recommended for the diagnosis of bone margins in cases of mandibular osteonecrosis. In this article, we report a case in which a generic violet light was used in order to activate bone fluorescence after the administration of tetracycline derivatives, as an alternative to a specific, more expensive equipment that is commercially available for this purpose. The patient had been using alendronate for osteoporosis, resulting in medication-related osteonecrosis of the jaws...

INTRODUCTION: Neck dissection is a part of the standard surgical procedure in the management of head and neck malignancy. Diplopia following neck dissection is a rare entity; hence, its diagnosis and management strategies needed to be discussed for prevention of its grave consequences. CASE REPORT: A 30-year-old male patient presented with binocular horizontal diplopia following total thyroidectomy and neck dissection. On evaluation, there was internal jugular vein (IJV) thrombosis followed by cerebral venous sinus thrombosis (CVST)...

The control of postoperative bleeding represents one of the main intercurrent events associated with soft tissue surgical procedures in the oral cavity. In this context, platelet-rich fibrin (PRF) membranes are materials with great potential for optimizing soft tissue healing and induction of hemostasis. This interventional case series describes the treatment of 10 patients with excisional biopsy of benign oral cavity lesions, following a screening sequence at the surgery clinic of a Brazilian dental school between the years of 2015 and 2017...

Three-dimensional (3-D) printing is a method of manufacturing in which materials like plastic or metal are deposited onto one another in layers to produce a 3-D object. Because of the complex anatomy of craniomaxillofacial structures, full recovery of craniomaxillofacial tissues from trauma, surgeries, or congenital malformations is extremely challenging. 3-D printing of scaffolds, tissue analogs, and organs has been proposed as an exciting alternative to address some of these key challenges in craniomaxillofacial surgery...
