A comprehensive study that compared acoustic rhinometry (AR) data to computed tomography (CT) data was performed to evaluate the accuracy of AR measurements in estimating nasal passage area and to assess its ability of quantifying paranasal sinus volume and ostium size in live humans. Twenty nasal passages of 10 healthy adults were examined by using AR and CT. Actual cross-sectional areas of th...

OBJECTIVES To investigate the up-regulation of chemokine ligand 20 (CCL20) in chronic rhinosinusitis mucosa and to localize the distribution of CCL20 in the human paranasal sinus mucosa. DESIGN Prospective study. SETTING Tertiary academic institution. PATIENTS Ten patients who underwent functional endoscopic sinus surgery for chronic rhinosinusitis without nasal polyps and 10 normal contr...

OBJECTIVE To report clinical characteristics and treatment outcomes of actinomycosis of the paranasal sinus. STUDY DESIGN Retrospective review. SUBJECTS AND METHODS The medical records of six patients with actinomycosis of the paranasal sinus between 1998 and 2006 were analyzed. RESULTS There were no immunocompromised patients and all lesions were unilateral. Only one patient had a histor...

Background This study aimed to present the correlation between headaches and anatomical changes within nasal cavity paranasal sinuses. Material methods: includes a literature search our observations of 24 patients regarding with sinus anatomy.

Alveolar rhabdomyosarcoma (RMS) has a predilection for the deep soft tissues of the extremities and mainly occurs in children. Although the tumor may originate in other sites, such as the nasal cavity or paranasal sinus, invasion of the orbit is unusual. We describe the clinicopathological features of 2 cases of alveolar RMS of the nasal cavity or paranasal sinus in adult patients with orbital ...

OBJECTIVE Immunoglobulin G4 (IgG4) related sclerosing disease (RSD) of the paranasal sinuses is a rare lesion of dense lymphoplasmacytic tissue, with a high proportion of IgG4+ plasma cells. We presented a rare case of IgG4-RSD with isolated involvement of the paranasal sinuses in the absence of multiorgan involvement. METHODS A case report and comprehensive literature review. RESULTS To ou...

Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinu...
