The place of coronal computed tomography (CT) in the assessment of patients prior to functional endoscopic sinus surgery (FESS) is well established. The ability to accurately correlate radiological and surgical anatomy enhances precision and safety during FESS. This pictorial essay reviews the conceptual anatomical framework that forms the basis of FESS.

Endoscopic sinus surgery is a standard procedure in the treatment of various pathologies such as chronic sinusitis or some types of neoplasms. The transnasal approach to tumours of paranasal sinuses is favourable due to functional and aesthetic reasons. We report a rare case of a large primary ectopic meningioma of the paranasal sinuses in a 48-year-old woman referred to the Otolaryngology Clin...

Surgical simulation is an effective tool used to teach many of the fundamental skills required to be a surgeon. Simulation‐based education with directed practice in surgi‐ cal training allows repeated practice in an environment to learn surgical skills, which do not cause harm to patients. There are several simulators developed for endoscopic sinus surgery training. Some simulators have undergo...

Fungus balls are a chronic and non-invasive fungal infection. Despite being relatively common in the paranasal sinuses, they rare nasal cavity. The etiology of fungus cavity is unknown. generally develop slowly asymptomatically. When symptomatic, can cause symptoms similar to those sinusitis or intranasal masses, such as obstruction, postnasal discharge, head face pain, smell perception disorde...

OBJECTIVES We evaluated the effect of endoscopic sinus surgery on irradiation-induced rhinosinusitis of the maxillary-sinus mucosa among patients with nasopharyngeal carcinoma (NPC). DESIGN Surgical outcomes were evaluated by changes to the ultrastructure of the antral mucosa and nasomucociliary clearance. METHODS Twenty-one NPC patients with irradiation-induced chronic sinusitis were enrol...

OBJECTIVES Patients who fail endoscopic drainage procedures for chronic frontal sinusitis often require obliteration of the frontal sinus with abdominal fat. The purpose of this study was to evaluate an endoscopic technique for frontal sinus obliteration. STUDY DESIGN AND SETTING Retrospective case-control. Thirty-five patients underwent frontal sinus obliteration using either an endoscopic (...

OBJECTIVE The aim of this study was to evaluate the efficacy of rehydration of Merocel nasal packs with prilocaine or levobupivacaine on reducing pain and discomfort of nasal packing removal in patients who had undergone septoplasties or endoscopic sinus surgery. STUDY DESIGN Prospective clinical study. Setting. Tertiary referral center. METHODS This prospective study was conducted on 72 pa...

The Messerklinger technique is an endoscopic approach to sinus surgery designed to be minimally invasive and preserve mucosa and hence physiological function. More recently there have been advocates for more radical endoscopic approaches to the frontal sinus such as the Modified Lothrop. This review discusses different approaches to frontal sinus surgery including any advantages and disadvantag...

OBJECTIVE To determine the efficacy of endoscopic surgery for chronic frontal sinusitis. DESIGN A prospective analysis of established measures of clinical outcome (Chronic Sinusitis Survey and Short Form 36) that was administered to patients before frontal sinus surgery and at intervals of 3 months, 6 months, and 1 year after surgery. INTERVENTIONS For limited disease, the frontal recess wa...

AIM Minimally invasive method for retrieving displaced objects like implants from the maxillary antrum with minimal complications. BACKGROUND Minimal invasive endoscopic surgery has been developed for various indications in the craniomaxillofacial area. CASE DESCRIPTION In this article, a technique for endoscopic removal of a dental implant displaced into the maxillary sinus is presented. A...
