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...
Aspergillus fumigatus infection due to primary infection of the ethmoid sinus affected the brain and orbit of an otherwise healthy elderly woman. Primary nasal sinus infection may be a chronic process analogous to aspergilloma of the lung: it may, however, assume a locally invasive course and spread to the orbit or brain, as in the case described. This form of Aspergillus infection is rare in E...

Malignant peripheral nerve sheath tumors are extremely rare soft tissue sarcomas. Among various locations, the trunk and extremities are the most commonly involved sites, with only 15% of such lesions occuring in head and neck region. Here, we report a case of a 74-year-old male who presented with forehead swelling and right eye deviation. Computed tomography images revealed a tumor involving t...
Intraosseous lipomas are very rare slow-growing benign tumors that may appear as congenital lesions or may be acquired (metaplasia from a pre-existing lipoma). Only a handful of head and neck cases have been reported in the literature. We present the first reported case of a solitary osteolipoma involving the sinonasal tract in a 66-year-old man with sinonasal symptoms. CT showed a lesion invol...
A 31-year-old lady presented to the otorhinolaryngology clinic complaining of right exophtalmus. Imaging studies revealed a right frontal sinus mass, suggestive of a mucocele, and fronto-ethmoidal ground glass opacification. In the operating room, the frontal sinuses were exposed through an osteoplastic flap, and connected to the nasal cavity through a Lothrop-like drainage pathway. The patholo...
OBJECTIVE To determine whether variations in gene expression exist at multiple subsites along the sinonasal tract in patients with chronic sinusitis with polyps and in healthy controls. STUDY DESIGN Prospective, controlled study. SETTING Academic medical center. SUBJECTS AND METHODS Tissue expression levels of 5 genes, previously found to be characteristic of ethmoid polyps, were measured...
A seven-year-old male presented with fever, left-sided facial redness, swelling and proptosis over a 24-hour period. He had noted left-sided toothache and rhinorrhea over the preceding week. On presentation, he stated that he was unable to see " anything, including light " from his left eye. On physical examination, the patient was febrile with left periorbital swelling and significant left-sid...
INTRODUCTION The concept of functional endoscopic sinus surgery (FESS) was established by Stammberger in 1986. When FESS is performed, the first encountered anatomical structure in the sinonasal tract is the uncinate process. Resection of the uncinate process is one of the important procedures in FESS, because the natural ostium of the maxillary sinus is located behind this process in most pati...
Meningiomas are slow-growing benign lesions that constitute ∼ 25% of primary intracranial tumours. Extracranial meningioma of the sphenoid sinus is extremely rare and may arise from ectopic arachnoid nests left behind during embryonic development. We present the case of a 61-year-old woman with left oculomotor nerve paralysis. Magnetic resonance imaging (MRI) revealed a 43 × 31 × 33 mm mass in ...
