Endoscopic skull base surgery has undergone rapid advancement in the past decade moving from pituitary surgery to suprasellar lesions and now to a myriad of lesions extending from the cribriform plate to C2 and laterally out to the infratemporal fossa and petrous apex. Evolution of several technological advances as well as advances in understanding of endoscopic anatomy and the development of s...
Introduction: Endoscopic sinus surgery is a common procedure performed by otolaryngologists. This study evaluated the efficacy of intravenous (IV) tranexamic acid (TA) on hemorrhage in patients undergoing elective endoscopic sinus surgery (ESS). Materials and Methods: The present study was performed in 170 patients scheduled for ESS surgery under general anesthesia in order to examine the ef...
Currently, the main application of endoscopic surgery relies on the middle ear cholesteatoma surgical treatment. However, in the natural evolution of the technique there are the steps toward of lateral skull base surgery and treatment of pathologic conditions of pertous bone. The endoscopic approaches to lateral skull base are (1) a transcanal exclusively endoscopic approach or (2) combined app...
OBJECTIVES/HYPOTHESIS Endoscopic ear surgery provides a minimally invasive approach to the middle ear. The disadvantage of endoscopic ear surgery is that it is a single-handed surgical technique. The nondominant hand of the surgeon is utilized for holding and manipulating the endoscope. This necessitated the need for the development of an endoscope holder that would allow both hands to be free ...
The aim of this study was to analyze the location, the cause and treatment of iatrogenic gastrointestinal perforations following therapeutic endoscopic procedures. Perforation occurred in 12 patients out of 3,389, giving cases occurred intraoperatively or postoperatively. Among them, 6 cases were closed by titanium clipping and 1 case by purse string suture. In another case after cap-assisted e...
Here we describe the procedures of endoscopic pituitary and skull base surgery in our institute. We also review the literature to reveal recent advances in this field. Endonasal approach via the sphenoid ostium was carried out for pituitary lesions without the nasal speculum. Postoperative nasal packing was basically not needed in such cases. For meningiomas, craniopharyngiomas, and giant pitui...
Endonasal skull base surgery is growing exponentially as a subspecialty. In recent years, advances in endoscopic techniques and intraoperative navigation systems have allowed us to expand the indications of endoscopic skull base surgery. Major skull base centers worldwide are addressing larger and more complex lesions using endoscopic techniques. As a consequence, the skull base defects are mor...
In the past 5 years, endoscopic neck surgery has been performed by various surgeons in Japan. However, many problems remain to be solved, including indications for this related in malignant thyroid tumors. For small thyroid cancers and legions suspected of malignancy, we found that we could obtain radicality in endoscopic neck surgery that was comparable to that attainable by conventional metho...
