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...

BACKGROUND/OBJECTIVES Mucosal leishmaniasis (ML) is a progressive disease that affects cartilage and bone structures of the nose and other upper respiratory tract structures. Complications associated with ML have been described, but there is a lack of studies that evaluate the structural changes of the nose and paranasal sinuses in ML using radiological methods. In this study, we aimed to asses...

BACKGROUND The issue of heat shock protein (HSP) 70 and anti-HSP70 antibodies in chronic rhinosinusitis (CRS) has never been explored. OBJECTIVE To determine the nasal secretion (NS) levels of HSP70 and anti-HSP70 antibodies in patients with CRS with nasal polyps (CRSwNP) and patients with CRS without nasal polyps (CRSsNP), and to evaluate their associations with CRS clinical severity and cor...

Introduction:  Eosinophilic mucin rhinosinusitis is a type of chronic rhinosinusitis (CRS). Diagnosis and treatment of this condition play a significant role in reducing the patients’ clinical symptoms. This type of rhinosinusitis has a higher relapse rate, compared to the other types. This disease is more resistant to treatment and more dependent on corticosteroid therapy, compared to the oth...

In order to obtain an objective Taiwanese control Lund-Mackay scoring (LMS) dataset, we performed a retrospective study that involved 600 patients, who had undergone head and neck CT scans between July 1st 2008 and November 12th 2010. After non-adults (less than 18 years old) and those with rhinosinusitis, head and neck trauma, epistaxis or cancer with head and neck radiotherapy were excluded, ...

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...

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...

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...
