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: to evaluate the most sensitive symptom to predict early recurrence of nasal polyposis. prospective longitudinal cohort study. tertiary university referral center with accredited otorhinolaryngology residency programs.  materials and methods: in this prospective study, we evaluated 62 patients with diffuse nasal polyposis. all patients underwent functional endoscopic sinus surgery....

OBJECTIVES/HYPOTHESIS The Messerklinger technique is an endoscopic approach to sinus surgery designed to be minimally invasive and preserve mucosa and therefore physiological function. More recently there have been advocates for more radical endoscopic approaches to the frontal sinus such as the modified Lothrop procedure. This study aims to determine the effectiveness of endoscopic frontal sin...

Aim: Review and describe the essential components of modern frontal sinus surgery. Background: Frontal sinus surgery has evolved considerably over the last century, and advances in imaging, optics, and instrumentation have contributed to contemporary treatment paradigms. Outcomes assessment has had an important role in identifying indications for surgery and future areas of research. Review res...

hemangiomas of the sinonasal tract are rare, and because these lesions lack the typical signs or symptoms, they can be confused with other malignant conditions. we report a case of cavernous hemangioma of the maxillary sinus in a 68-year-old man that was completely resected by endoscopic sinus surgery. although computed tomography (ct) and magnetic resonance imaging (mri) showed several enhanci...

Introduction: There are suspended fungal spores in the air and in the nasal mucosa of adults, especially in areas with a humid climate. Several studies have revealed the role of fungi in the pathogenesis of chronic rhinosinusitis (CRS) in recent years but it is a topic of controversy, especially in regions with low humidity. The aim of this study was to evaluate the prevalence of fungal specie...
