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 Although common variable immunodeficiency (CVID) is associated with sinopulmonary disease, there are no previous systematic evaluations comparing computed tomographic (CT) sinus imaging with immunoglobulin measurements in patients with this condition. METHODS We performed a retrospective review by a blinded observer using the Lund-Mackay numerical scoring scale as well as a visual ...

The paranasal sinuses were prospectively evaluated by CT, clinical history, and physical examination in infants and children having cranial CT for indications unrelated to upper respiratory inflammation (URI). One hundred and one CT scans were studied, and sinus abnormalities were detected in 18% of patients older than 1 year and without signs or symptoms of URI. When signs and/or symptoms of r...

Introduction. Complications can occur as a consequence of both acute and chronic sinusitis. Most frequently complications are caused by acute ethmoiditis or frontal sinusitis. The complications of paranasal sinusitis are divided into intraorbital, intracranial and osteomyelitis. The children with complications of paranasal sinusitis require hospitalization, treatment with combined intravenous a...

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 ...
