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...

UNLABELLED Chronic rhinosinusitis is a disease of undefined etiology that significantly impacts the quality of life of its patients. Various studies carried out in countries other than Brazil have shown endoscopic sinus surgery as an effective means of treating this condition. OBJECTIVE This study aims to analyze, with the aid of SNOT-20, the association between endoscopic sinus surgery and d...

Pseudoaneurysm is defined as blood leaking out of a vessel that does not have true 3 arterial walls like a true aneurysm, and is susceptible to rupture. Only 4 patients of pseudoaneurysm after endoscopic sinus surgery have been reported so far in English literature. Recently, the authors encountered a pseudoaneurysm in the internal maxillary artery after endoscopic sinus surgery, which was imme...

The occurrences of pneumothorax and pneumomediastinum are rare, but considered to be potentially life-threatening conditions in patients undergoing functional endoscopic sinus surgery under general anesthesia. Tracheobronchial rupture may results in serious complications, such as pneumothorax and pneumomediastinum. It may occur accidentally by endotracheal tube when the patient's neck is flexed...

We describe an interactive, intraoperative imaging-guided method for performing endoscopic sinus surgery (ESS) within a vertically open MR system. The procedure was performed with intraoperative imaging using a 0.5-T magnet with a 56-cm vertical gap. Interactive control of imaging planes was accomplished by optical tracking with two infrared light-emitting diodes mounted on an aspirator probe. ...

Functional endoscopic sinus surgery' (FESS) is a common otolaryngologic procedure, with over 250,000 operations performed annually. Computerized surgical navigation systems are available to assist the rhinologic surgeon in the complex dissection required for FESS. Our objective was to determine whether this system provided quantifiable benefits in FESS. We retrospectively reviewed 203 patients ...

BACKGROUND Bleeding during functional endoscopic sinus surgery is a challenge for the quality of the surgical field for surgeons. This study aimed to evaluate the effect of desmopressin premedication on blood loss and the quality of the surgical field in endoscopic sinus surgery. METHODS A total of 90 American Society of Anesthesiologists physical status I-II patients underwent endoscopic sin...

conclusions surgeons should consider the possibility of existence of other mucoceles when they find a large downstream sinus mucocele obstructing the ostia of upstream sinuses on computed tomography scans. introduction mucoceles of the paranasal sinuses are relatively rare. a very busy otolaryngology department does not have more than a few cases each year. bilateral, multiple, and multiloculat...
