the author studied anatomical variations of the origin of the chorda tympani nerve from the mastoid portion of the facial nerve. the studies were performed on 200 specimens of human temporal bone. it was found that the chorda tympani may arise from the facial nerve in three levels: most commonly from the mid third of its mastoid segment (70%), less commonly from the proximal third (20%), and ve...

Introduction: Coverage of bone grafts is very important in reconstructive surgery. In edentulous alveolar ridges this coverage is particularly important for supporting dental prostheses. Here we present the case of a patient with a large deficient maxillary anterior region that was reconstructed with a bilateral palatal submucosal periosteal connective tissue flap: a soft tissue reserve for up...

Objectives: The purpose of this study was to investigate the responsiveness absolute error estimated speaking fundamental frequency (AEF0) after intervention voice disorders. correlation between changes in AEF0 measures and multidimensional measurements were explored. Usefulness (ΔAEF0) for predicting vocal improvement also Methods: 30 male female patients with benign fold lesions participated ...

Surgery is at a crossroads of complexity. However, there is a potential path toward patient safety. One such course is to leverage computer and robotic assist techniques in the reduction and interception of error in the perioperative environment. This white paper attempts to facilitate the road toward realizing that promise by outlining a research agenda. The paper will briefly review the curre...

Patellar instability is a common clinical problem encountered by orthopedic surgeons specializing in the knee. For patients with chronic lateral patellar instability, the standard surgical approach is to stabilize the patella through a medial patellofemoral ligament (MPFL) reconstruction. Foreseeably, an increasing number of revision surgeries of the reconstructed MPFL will be seen in upcoming ...

Minimally invasive endoscope based abdominal procedures provide potential advantages over conventional open surgery such as reduced trauma, shorter hospital stay, and quick recovery. One major limitation of using this technique is the narrow view of the endoscope and the lack of proper 3D context of the surgical site. In this paper, we propose a rapid and accurate method to align intraoperative...
