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...

Abstract Objective The extent of surgery, the type device used and head position may influence nasal irrigation. aim this study was to determine effectiveness topical irrigant delivery paranasal sinuses according these factors. Method Four cadaveric heads underwent four stepwise endoscopic dissections. Irrigations were evaluated after every stage using different devices (squeeze-bottle, gravity...

Mucocele of the paranasal sinuses is a distinct clinicopathologic entity in which there is obstruction of the sinus cavity outflow tract, resulting in expansion of the sinus walls. The histologic features are quite nonspecific, requiring clinical, radiologic, and pathologic correlation. Most of these lesions result from increased pressure in the sinus due to sinus outlet obstruction, usually as...

introduction a mucocele is an epithelial-lined, mucus-containing sac that can fill the sinus completely and expand gradually. mucopyocele is an infected mucocele. case report we presented a case of left maxillary mucopyocele in a 58-year-old man that developed after radiotherapy for nasopharyngeal carcinoma. computed tomography scan showed opacification of the left maxillary sinus expanding thr...

Two young adult males presented with paranasal sinus osteoma associated with mucocele. A 20-year-old man presented with headache and seizure, and another 20-year-old man presented with headache, frontal deformity, and visual disturbances. Both patients underwent surgery and satisfactory results were obtained. Isolated paranasal sinus osteomas are benign and slow-growing tumors, but may become m...

Infections involving paranasal sinuses and nasal cavities is one of the common public health problem in all age groups. Functional endoscopic sinus surgery has revolutionized in the treatment of sinusitis. MDCT has been the most ideal investigation in the assessment of paranasal sinuses especially in the identification of various anatomical variations that predispose to development of sinus inf...

Although a variety of theories have been proposed about functions of the paranasal sinuses, not one is clear today. Nonetheless, paranasal sinus-related diseases are associated with a high rate of morbidities. Therefore, it is essential to identify the structure and pathophysiology of the paranasal sinuses. Computed tomography (CT) is a valuable tool displaying anatomic variations and diseases....

OBJECTIVE Assess paranasal sinus distribution of topical solutions following endoscopic sinus surgery (ESS) using various delivery devices. STUDY DESIGN Experimental prospective study. SUBJECTS AND METHODS Ten cadaver sinus systems were irrigated with Gastroview before surgery, after ESS, and after medial maxillectomy. Delivery was via pressurized spray (NasaMist), neti pot (NasaFlo), and s...

n-Butyl cyanoacrylate (n-BCA) embolization of a hemorrhagic pseudoaneurysmal arteriovenous fistula of the sphenopalatine artery in a patient with paranasal sinus squamous cell carcinoma treated with regional surgery and radiation has, to our knowledge, not been previously reported.
