Frontal sinus fractures are of surgical importance because of the microbial flora covering the frontal air sinus and it's proximity with the duramater and brain. There is an increased risk of meningitis when fracture of the posterior wall of the frontal sinus is associated with a dural tear. In this condition, communication occurs between the contaminated space of the air sinus and the intr...

Introduction Perforation of maxillary sinus mucous membrane is of the most prevalent complication during open sinus lift surgery. Moreover, such complication can usually be managed by an absorbable membrane. As far as absorbable membranes are concerned, decellularized maxillary sinus mucous membranes, which is an extracellular matrix, can be used as a biologic scaffold and insulating membrane ...

patients with valvular heart disease suffer from atrial fibrillation for more than 12 months after valve surgery and have a low probability of remaining in sinus rhythm. we performed an intra-operative procedure similar to surgical maze ііі procedure for conversion of this arrhythmia to sinus rhythm. we did this study to evaluate the efficacy of this procedure to restore the sinus rhythm in pat...

INTRODUCTION Frontal sinus mucoceles are the commonest among all paranasal mucoceles. With introduction of functional endoscopic sinus surgery, surgeons prefer endoscopic management of sinus mucoceles, but lesions that appear in the lateral part of the frontal sinus can be difficult to access and often need external approaches. CASE PRESENTATION We described a lateral frontal sinus mucocele w...

BACKGROUND Maxillary sinus mucoceles are relatively rare among all paranasal sinus mucoceles. With the introduction of endoscopic sinus surgical techniques, rhinologic surgeons prefer transnasal endoscopic management of sinus mucoceles. The aim of this study is to describe the clinical presentation of maxillary sinus mucoceles and to establish the efficacy of endoscopic management of sinus muco...

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...
