Introduction: Mucoceles of the paranasal sinuses are relatively rare. A very busy otolaryngology department does not have more than a few cases each year. Bilateral, multiple, and multiloculated cases are extremely unusual. Case Presentation: We report a 74-year-old man with two separate mucoceles in left ethmoid and frontal sinuses with pansinusitis. After marsupialization of mucoceles and fun...

OBJECTIVES/HYPOTHESIS The purpose of this study is to test the theory that the paranasal sinuses serve a protective function for the central nervous system and special sensory organs. STUDY DESIGN Nonrandomized experimental trauma study with fresh human cadavers. METHODS Fresh human cadaver heads were obtained and the sinuses on one side underwent endoscopic endonasal sinus surgery and were...

Isolated or solitary neurofibromas of the paranasal sinuses are rare. Mostly, they involve the maxillary sinus and so far, a solitary neurofibroma of the frontal sinus has never been reported in the literature. We present a case of frontal sinus neurofibroma treated successfully with surgical excision. A 28-year-old male presented with forehead swelling and computed tomography images revealed a...

Objective: To determine the Keros classification and asymmetrical distribution rates of the ethmoid roof and the frequency of anatomic variations of the paranasal sinuses. Materials and Methods: Paranasal sinus scans of 500 patients obtained using computed tomography were evaluated retrospectively. Measurements were performed using a coronal plan with right-left comparison and with distance mea...

Back Ground: Sinusitis affects millions of people each year and is a major cause of concern worldwide. Chronic rhino-sinusitis is an inflammation of Nose and Paranasal sinuses and the aetiology of it is multifactorial. Anatomical variations of nose and paranasal sinuses are one of the most important aetiological factor for chronic sinusitis. The approach to patients with chronic rhinosinusitis ...

INTRODUCTION The paranasal sinuses mucoceles are benign expansive cystic lesions that occur rarely in the sphenoid sinus and contain mucous material enclosed by cylindrical pseudostratified epithelium. OBJECTIVE To report one case of sphenoid sinus mucocele that occurred with headache and was submitted to surgical treatment through endonasal endoscopy approach. CASE REPORT 59-year-old male ...

Cholesterol granulomas are common in the mastoid antrum and air cells of the temporal bone. In the paranasal sinuses, especially in the frontal sinus, they have occasionally been mentioned in the literature. The pathogenesis is unknown, but the majority of the authors support the concept of airway obstruction in the cells well pneumatised of temporal bone and paranasal sinuses. The authors repo...

Paranasal sinus cancers are rare, aggressive tumours that are usually diagnosed at an advanced stage. They differ from other upper aerodigestive tract tumours in terms of risk factors (wood dust exposure) and premalignant lesions (inverted papillomas). The diagnosis should be suspected in the presence of unilateral and continuous nasal sinus symptoms or bone lysis or a heterogeneous opacity on ...
