HYPOTHESIS Exposure to certain new surgical instruments and operating room devices during procedures could cause hearing damage to patients and personnel. BACKGROUND Surgical instruments and related equipment generate significant sound levels during routine usage. Both patients and physicians are exposed to these levels during the operative cases, many of which can last for hours. The noise l...

BACKGROUND Recently, several transoral approaches for minimally invasive surgery have been developed for oropharyngeal cancer. However, all approaches have certain disadvantages. Therefore, we built and examined new surgical environments for improving the situation. METHODS Endoscopic transoral resection using a pharyngeal retractor or distending laryngoscope, rigid videoendoscope, and laparo...

There is substantial historical evidence to support the prevalence of surgical practice during ancient times in the subcontinent of India. However, in contrast to the contemporaneous Greek and Roman periods, there is a notable absence of any archaeological finds in the form of surgical instruments. Inquiries to major museums and personal contacts have not been fruitful. This lack of relevant ar...

the ameloblastic carcinoma is a rare malignant counterpart of the ameloblastoma. ameloblastic carcinoma is a malignant lesion with characteristic histologic features and behavior that dictates a more aggressive surgical approach than that of a simple ameloblastoma. however, reliable evidence of its biologic activity is currently unavailable due to the scarcity of well-documented cases. we prese...

Surgical techniques rely heavily on adequate visualization of target anatomy. Particularly in laparoscopic and robotic laparoscopic surgery, the operative anatomy and the general view of the operative field is removed from the surgeon’s direct vision. Manipulation of peripheral anatomy (i.e. retraction) may lead to ischemia, infarction, and mechanical disruption. The primary goal of our researc...

INTRODUCTION Retained sponges and instruments (RSI) due to surgery are a recognised medical 'never event' and have catastrophic implications for patients, healthcare professionals and medical care providers. The aim of this review was to elucidate the extent of the problem of RSI and to identify preventative strategies. METHODS A comprehensive literature search was performed on MEDLINE(®), Em...

This most interesting monograph was presented as a thesis which formed part of the examination for the degree of M. D. of the University of Aberdeen, and it gained for its author "Highest Honours." The object of the book is to lay before the student of medical history an account of the various instruments with which the ancient Greeks and Roman surgeons prosecuted their craft. To understand any...
