PURPOSE To delineate the relationship between the optic nerves and the posterior paranasal sinuses using CT data. METHODS Direct coronal sinus CT scans of 150 consecutive patients with chronic inflammatory sinus disease were reviewed by two radiologists. Axial oblique reconstructions along the course of the optic nerve were obtained for the first 100 patients. The direct relationship between ...

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...

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 ...

A case report on dentin dysplasia type I, a congenital disease (autosomal dominant gene defect) affecting deciduous and permanent teeth, is depicted including representations of clinical and histological features, X-ray and CT-findings. Therapy includes extraction of all teeth, ectomization of cystic alteration, revision of paranasal sinus. Aesthetic and functional rehabilitation by means of in...

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...

PURPOSE The aim of this study was to investigate paranasal sinus pathoses detected on cone-beam computed tomography (CBCT) in an adult population. PATIENTS AND METHODS Three observers retrospectively inspected 353 consecutive CBCT scans obtained in a dentomaxillofacial radiology department for paranasal sinus pathoses. Descriptive statistics and chi-square tests were used to determine the pre...
