A pneumocele is an abnormal dilatation of a paranasal sinus, most commonly affecting the frontal sinus. Although the etiology of pneumocele is not entirely known, several causative factors have been suggested including trauma, surgery, tumor and infection. We report here a case of post-traumatic pneumocele of the frontal sinus following a head trauma.

purpose : to present a patient with radiation chiasma neuropathy, secondary to radiotherapy of paranasal sinus lymphoma who was referred for evaluation of gradual decrease of vision in both eyes case report : the patient was a 38-year-old male, with history of right maxillary sinus lymphoma, who underwent surgery, chemotherapy and radiation therapy. one year after radiotherapy, he noticed gradu...

Paranasal sinus mucoceles are benign, locally expansile cyst-like masses that are filled with mucus and lined with epithelium. Most occur in the frontal sinus. Maxillary sinus mucoceles are presumably uncommon in the United States and European countries, although they have been frequently reported in Japan, particularly following Caldwell-Luc surgery. Clinical symptoms may not appear for at lea...

OBJECTIVES In the paranasal sinus fungal ball (SFB), changes that occur in the underlying bone have not been well described. Recently, bacterial coinfection has been reported in patients with paranasal SFB. We evaluated whether bone changes occur in patients with unilateral maxillary SFB, and also how bacteria in an SFB affect the bony wall of the sinus. METHODS A retrospective study of patie...

OBJECTIVES We present the clinical and radiological features, treatment protocols, and medium-long-term results of our patients following surgery for paranasal sinus mucocele, along with a review of the relevant literature. MATERIALS AND METHODS A total of 18 patients (11 women and 7 men) who underwent surgery for paranasal sinus mucocele at Kocaeli University Faculty of Medicine, Department ...

INTRODUCTION Mucoceles are slow-growing, benign lesions found in the paranasal sinuses that are locally destructive, causing bony resorption an displacement of adjacent structures. We present our experience in the surgical treatment of these lesions. METHODS This was a retrospective review of 58 paranasal sinus mucoceles in 54 patients between 1989 and 2012. We describe patient age and sex, m...

Objective. To investigate the clinical features of paranasal sinus osteomas and to estimate the growth rate of these tumors in a large series of patients. Design. Case series with chart review. Setting. University hospital, tertiary referral center. Subjects and Methods. The authors retrospectively reviewed the paranasal sinus tomography scans that were taken between January 1997 and April 2008...

INTRODUCTION The aim of this work was to analyze the occurrence of inverted papilloma within the nose and paranasal sinuses, the extent of lesions and the clinical course in the patients who underwent endoscopic surgery. MATERIALS AND METHODS Between the years of 2006-2012, at the Department of Otolaryngology and Laryngological Oncology, 2295 patients were subjected to surgery due to paranasa...

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...
