Computerised tomography (CT) scan imaging techniques acts as a guide for functional endoscopic sinus surgery (FESS). It plays a vital role in the successful outcome of the treatment and management of the paranasal sinus variations. The frequent predisposing factors of chronic sinusitis are the anatomical variations of the paranasal sinus and nasal region. Computed tomography (CT) scan plays a f...

BACKGROUND We hypothesized that higher body mass index (BMI) was associated with increased prevalence of paranasal sinus disease and examined the hypothesis in Japanese adults. METHODS This was a cross-sectional study including 1350 Japanese adults aged 40 years or more who participated in a health check-up program focusing on brain diseases and metabolic syndrome. Participants were divided i...

BACKGROUND Diseases of nose and paranasal sinuses can complicate to involve the orbit and other surrounding structures because of their close proximity. These diseases are usually infective or can be neoplastic in origin. METHOD All the patients presenting in ENT or Eye Departments of Ayub Teaching Hospital during the one year study period who had complicated nose or paranasal sinus disease w...

Background: Chronic rhinosinusitis (CRS) refers to a group of disorders characterized by inflammation of the mucosa of the paranasal sinuses. Computed tomography (CT) scans used as the gold standard diagnostic modality of nose and paranasal sinus diseases. There has been a lot of studies regarding the anatomic variations leading to pathogenesis of paranasal sinus diseases. Considerable progress...

In normal upper airways, nitric oxide is generated by the paranasal sinus epithelium and then diffuses into the nasal cavities. This study examined whether or not nasal NO concentration is affected by paranasal sinus inflammatory diseases. The influence of obstruction (nasal polyposis) and/or inflammation (allergy or chronic sinusitis) of the paranasal sinuses on nasal NO concentration was eval...
