Osteoma is the most common benign tumour of the nose and paranasal sinuses. However, involvement of the sphenoid sinus by osteoma is rare. Most of the time, patients with paranasal sinus osteoma are asymptomatic. However, symptoms may present, depending on the location and extension of the tumour. We report a case of a patient with sphenoethmoidal osteoma found incidentally on imaging, with evi...

Background: Chronic rhinosinusitis (CRS) refers to a group of disorders characterized by inflammation of the mucosa of the paranasal sinuses. Nasal endoscopy and computed tomography (CT) scans are successfully used as diagnostic modalities of nose and paranasal sinus diseases. There have been many studies regarding the anatomic variations leading to pathogenesis of paranasal sinus diseases. Con...

Antroliths are calcified masses within the maxillary sinus and are detected incidentally on radiological examinations. They occur as a result of the solidification of mucus and nasal debris by mineral salts, calcium, magnesium phosphate and carbonate. The origin of the nidus of calcification may be extrinsic (foreign body in sinus) or intrinsic (stagnant mucus and fungal ball). Inverted papillo...

Fungal infections of the nose and paranasal sinuses are frequent in this part of the world. One aspect of the increased frequency is the improved clinical, radiological and pathological diagnostic methods that are now available. Aspergillus is the commonest infecting fungus of the nose and the paranasal sinus. It is mainly a saprophytic spore producing fungus and can cause invasive and non-inva...

The paranasal sinuses and the mastoid air-cell systems are evaginations of the mucous membrane of the nasal and nasopharyngeal cavities . Separate theories regarding their pneumatization have been suggested. However, correlation studies between the two systems giving a possible clue to a common pneumatizing process have been few (1 , 2]. One hundred adult patients without ear disease and minima...

Aim: The authors hereby present a case of giant frontal osteoma, i.e., not so rare but in the present case, the size and orbital involvement of this tumor make it a unique case. Introduction: Paranasal sinus osteoma most commonly presents in frontal sinuses. Their growth is slow, and patients usually seek physician’s advice only for cosmetic reasons. Case description: A 20-year-old male present...
