The lateral limit of endoscopic endonasal surgery has yet to be defined. The aim of this study was to investigate the lateral limit of endoscopic endonasal surgery at the level of the sphenoid sinus. Access from the sphenoid sinus to the middle cranial fossa through the cavernous sinus triangles was evaluated by cadaver dissection. Anatomical analysis demonstrated that the medial temporal dura ...

OBJECTIVE To measure the intra-sinus pressure and the maxillary sinus functional efficiency (MSFE) in individuals with chronic facial pain after conservative or conventional endoscopic maxillary surgery, as well as in controls. METHOD Sinus manometry was performed 5 times during inhalation. RESULTS The resemblance of pressure values comparing those treated with minimally invasive surgery an...

Introduction: Blood loss is a common concern during functional endoscopic sinus surgery (FESS). The present study aimed to evaluate the efficacy of dexmedetomidine (DEX) in intraoperative bleeding and surgical field in FESS.   Materials and Methods: This double-blind randomized clinical trial was conducted on 72 patients within the age range of 16-60 years who underwent ...

tranexamic acid (ta) is an antifibrinolytic agent which reduces bleeding following certain surgical procedures. the present study was performed on 56 patients, scheduled for elective endoscopic sinus surgery under general anesthesia, to examine the effects of topical ta on providing a bloodless surgical field and evaluate the bleeding volume. the study comprised 26 patients who received topical...

Introduction: Endoscopic endonasal is one of the technological advances used as a supporting examination for diagnosis and therapy. This procedure often to evaluate medical problems nose sinuses, such functional endoscopic sinus surgery or FESS (functional surgery), turbinoplasty, septoplasty. Surgery can be difficult manage because there bleeding due large supply blood vessels in area. study a...
