BACKGROUND The paranasal sinuses are intimately related to the orbit and consequently sinus disease or surgery may cause severe orbital complications. Complications are rare but can result in serious morbidity, the most devastating of which is severe visual loss. METHODS A retrospective review was undertaken of four cases of severe orbital trauma during endoscopic sinus surgery. RESULTS All...

Project Review Our project is titled “Image Processing for Video-CT Registration in Sinus Surgery.” We aim to develop an occluding contour extraction algorithm that can reliably and efficiently find edges in sinus surgery endoscopic videos. Our project is a critical component of a larger one that aims to enhance magnetic tracker resolution in sinus surgery. The proposed registration algorithm i...

CONTEXT Perioperative antibiotics are widely used to improve the outcomes of endoscopic sinus surgery. OBJECTIVE The aim of this study was to summarize the evidence on the effect of perioperative antibiotic prophylaxis on outcomes of endoscopic sinus surgery. DATA SOURCES AND REVIEW METHODS We searched electronic databases from inception through May 2011 for any relevant clinical trials or ...

INTRODUCTION Choanal polyps are a benign pathology arising in the sinusal mucosa and entering the nasal fossa heading for the choana. It is a unilateral condition mainly affecting young people. It must be surgically removed, with exeresis of both the nasal and the sinusal lesions. MATERIAL AND METHOD A retrospective review has been made of 51 patients treated for choanal polyp at our centre. ...

INTRODUCTION Anatomic variations of the paranasal sinuses are very common. The paranasal sinus anatomy should be carefully examined prior to performing endoscopic sinus surgery in terms of both existent pathologies and anatomic variations. The anatomy of the paranasal sinuses and its variations have gained importance, along with advances in coronal paranasal sinus computed tomography and extens...

Objectives. Organized hematoma (OH) is a rare, nonneoplastic, hemorrhagic lesion causing mucosal swelling and bone thinning, mainly in the maxillary sinus. We aimed to clarify the clinical presentation and treatment of OH. Methods. Three cases of maxillary sinus OH and a literature review are presented. Results. Three men aged 16-40 years complained of nasal obstruction, frequent epistaxis, and...

Keywords Endoscopic sinus surgery Eosinophil Nasal polyposi Paranasal sinus Sinonasal polyps Nasal polyposis is one of the chronic airway diseases, which affects the patient's quality of life in different ways. There are various complications along with nasal polyposis, which might be cured by drug administration. Due to failure of pharmacotherapy effects, various surgical approaches might be u...

A conchal non-pneumatized sphenoid sinus was previously considered to be a contraindication to the endoscopic transsphenoidal route to the sella due to its small sellar floor and poor anatomical landmarks, such as the optic nerve canal, opticocarotid recess and internal carotid arteries canal. The present study aimed to investigate the methodology and characteristics of the endoscopic transsphe...

Corticosteroids are the mainstay of treatment for refractory chronic rhinosinusitis. The off-label use of steroid-eluting stents has increasingly gained popularity in functional endoscopic sinus surgery for decreasing postoperative inflammation and synechiae formation. However, there is a paucity of data outlining the safety profile of this device despite its widespread use. This study was desi...
