OBJECTIVE To determine the accuracy of computed tomography (CT) in the diagnosis of pediatric chronic rhinosinusitis (CRS). SETTING Multi-institutional prospective dual cohort study. METHODS Two cohorts of children undergoing CT of the paranasal sinuses were prospectively evaluated. The first cohort consisted of children undergoing CT in preparation for endoscopic sinus surgery (diseased gr...

introduction: the surgical management of chronic frontal sinus disorders remains a challenge for rhinologists. the aim of this study was to evaluate the result of draf iii in a series of patients who underwent this procedure.   materials and methods: twenty patients were included in this study. demographic data, history of prior surgery, asthma,  aspirin sensitivity and lund–mackay score were r...

UNLABELLED Many score methods have been created to measure paranasal sinus abnormalities seen under CT scan. Currently, the Lund-Mackay staging system is widely accepted. However, its results may be affected by the development in children. AIM To assess the precision and accuracy of a new tomography score, called "opacification-development ratio". It translates the percentage of sinus area th...

PURPOSE Concha bullosa (CB) alters the intranasal anatomy and may influence the buffering of inhalant allergens and the inflammatory microenvironment central to chronic rhinosinusitis (CRS). By investigating the link between allergies and CB, we can examine this theoretical benefit, which has implications on the extent of resection in endoscopic sinus surgery. METHODS Forty-three adults treat...

A 69 year-old man, with bilateral inflamed sinonasal polyps that had been treated medically for years, referred for surgical treatment suffering from moderate progressive bilateral nasal obstruction, sinus pressure with no rhinorrhoea or other symptoms and typical bilateral inflamed polyps emerging from the middle meatus, not exceeding the level of the lower concha (Endoscopic Appearance Score ...

BACKGROUND Although chronic rhinosinusitis (CRS) is increasing in prevalence and incidence, its diagnosis and treatment still pose a challenge. The Task Force on rhinosinusitis (TFR) advocates the use of symptom based criteria. However, many otorhinolaryngologists depend on diagnostic nasal endoscopy and computed tomography (CT) of paranasal sinuses for diagnosis of CRS. Computed tomography has...

The association of bronchiectasis with chronic rhinosinusitis (CRS) has been reported. However, apart from primary ciliary dyskinesia (PCD) and cystic fibrosis (CF), predisposing conditions have not been established. We aimed to define clinical and laboratory features that differentiate patients with bronchiectasis with upper airway symptoms (UASs) and without PCD from patients without UASs. We...

Background. Preoperative imaging of the nose and paranasal sinus is standard in otorhinolaryngology. Previous studies on phantoms demonstrated the potential for dose reduction of cone beam computed tomography (CBCT) by varying the application parameters. Methodology. Based on previous studies, the standard protocol of paranasal sinus imaging by CBCT was altered. One hundred and fifty examinatio...
