Two case reports of a modified sagittal split osteotomy of the ramus of the mandible are presented which illustrate a technically simplified modality of treating various dentofacial abnormalities. A brief review of the literature is presented and observations are made on the procedures. The need for future documentation of intraoperative and postoperative results on this type of procedure is re...

background transurethral resection of the prostate (turp) is the most common surgical treatment for benign prostatic hyperplasia. objectives the aim of the present study was to compare the conventional bipolar transurethral resection of prostate (turp) with a modified transurethral resection of the prostate (m-turp) in men with mild to moderate symptoms of benign prostatic hyperplasia. patients...

This paper is the first discussion on the registration of intraoperative MRI and endoscope using Polaris and MRI-compatible endoscope manipulator. An endoscope has been popular in minimally invasive surgery due to its less-invasive, realtime, and fine observations in body cavity. However, because its view is so limited, it's difficult to know the surrounding structures. Intraoperative MRI has b...

Background: Intraoperative awareness is a rare but extremely unfavourable phenomenon affecting 0.1–0.2% of patients who undergo surgery under general anaesthesia. The event exposes patients to stress and its remote, severe outcomes. The aim of the present study was to determine the incidence of intraoperative awareness in patients undergoing general anaesthesia. Methods: The observational quest...

BACKGROUND The risk of technical failure during operations is recognized, but there is evidence that further improvements in safety depend on systems factors, in particular, effective team skills. The hypotheses that small problems can escalate to more serious situations and that effective teamwork can prevent the development of serious situations, were examined to develop a method to assess th...
