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 ...

Introduction  Many patients undergoing functional endoscopic sinus surgery still have an uncontrolled clinical disease in the late post-operative period. Up to 11.4% of the patients will require a revision surgery. Findings such as the residual uncinated process and the lateralization of the middle turbinate were considered by some studies as being responsible for failure in the primary surgery...

Sinus mycetoma is a dense accumulation of hyphae that form a rounded mass within the mucosal confines of a paranasal sinus. The aim of this study was to present a case series of three patients with maxillary sinus mycetoma and to describe their radiographic presentations. Three cases are presented. The first two, a 44-year-old woman and an 88 year-old man, both diabetics, were referred to maxil...

Surgical ciliated cyst is uncommon in Western countries but frequently reported in Asian populations as a delayed complication of surgery, with inclusion in the bone of nasal or sinus mucosa. Isolated cases have also been reported in the mandible after orthognathic surgery. We report a case in the maxillary region three years after radical sinus surgery for chronic sinusitis. Intraoral examinat...

Draf's drainage surgery, an endonasal micro-endoscopic approach to establish one of three types of frontal sinus drainage, is becoming the standard operative procedure in Europe and America especially for recurrent cases. We reported a recurrent frontal sinus cyst that we treated in accordance with Draf's drainage surgery under the navigation system. The patient was an 81-year-old male, who com...

The anatomical variations of the nasal and sinus paranasal can cause headaches. most common variants have deviated septum, concha bullosa, agger nasi cells. These narrowing osteomeatal complex. Computed tomography was primary modality for evaluating sinuses in diagnosis management. Functional endoscopic surgery generally performed to restore sinuses' drainage ventilation variations. It has been...

Objective. We report the first utilisation of transnasal marsupialization to treat a keratocystic odontogenic tumor in the maxillary sinus of a 37-year-old man. Case Report. A 37-year-old man presented with a nasal discharge and right odontalgia. Computed tomography revealed an expanding cystic lesion with a calcificated wall containing an impacted tooth in the right maxillary sinus. The diagno...

BACKGROUND Silent sinus or imploding antrum syndrome is a very rare condition, consisting of a usually asymptomatic spontaneous collapse of the sinus walls and floor of the orbit. It is associated with negative pressures, and when this occurs, it presents with manifestations such as enophthalmos, hypoglobus, and tilt flow orbital floor. As its incidence is very low, it is frequently missed as a...

INTRODUCTION Endoscopic sinus surgery is a minimally invasive procedure used to restore normal sinus ventilation and mucociliary function. It is a routine otolaryngology procedure with a success rate of about 90% for symptomatic improvement in patients with refractory chronic rhinosinusitis. Because of the proximity of the paranasal sinuses to the brain and the orbit, it cannot be performed wit...
