OBJECTIVE The purpose of this study was to present the morphometry and pneumatization of the sphenoid sinus in detail for the neurosurgeon for transnasal approach to the hypophyseal tumors and especially for functional endoscopic sinus surgery. METHODS One hundred and eighty midsagittal magnetic resonance images, 48 bones and 29 hemi-sectioned cadaveric heads obtained from Ege University, Fac...

Introduction Inverted papilloma is a rare benign tumor of the nasal fossa, which usually originates from its lateral wall. Only 5% of cases demonstrate exclusive sinus involvement. Primary sphenoid sinus involvement is even rarer. Although considered a benign lesion, the tumor has a potentially invasive nature and has also been found to have an associated malignancy rate of 7 to 15%. Objectives...

Agenesis of paranasal sinuses is an uncommon finding mainly seen in the frontal and maxillary sinuses. Agenesis of sphenoid sinuses is an extremely rare condition. In this article, we present an 18-year-old female patient suffering from headache and nasal obstruction without any skeletal or cranial anomalies. Axial, coronal and sagittal computed tomography revealed absent sphenoid sinuses. Surg...

A large Rathke's cyst was marsupialized into the sphenoid sinus of a 45-year old woman who presented with headache, polydipsia, cessation of menses and diplopia. A brief review of cases is presented.

INTRODUCTION To describe the unusual manifestation of a giant frontal sinus mucocele. CLINICAL PICTURE A 33-year-old female presented with blurring of vision in the left eye, periorbital swelling and a painless forehead mass. There was proptosis, partial ptosis, and an elongated, soft, subcutaneous mass over the left side of the forehead. CT scan showed a mass arising from the frontal sinus w...

Isolated sphenoid sinus lesions are an uncommon entity and present with non-specific symptoms. In this case report, the patient presented with a history of headaches for a duration of one month without sinonasal symptoms. A computed tomography scan showed a soft tissue mass occupying the sphenoid sinus. An endoscopic biopsy revealed fungal infection. Endoscopic wide sphenoidotomy with excision ...

An 85-year-old man complained of a 2-month history of pain on the left side of his face. Brain computed tomography (CT) and magnetic resonance imaging/magnetic resonance angiography did not clearly show any intracranial abnormality and only showed fluid effusion in his left sphenoid sinus. Filamentous fungi were detected from the left sphenoid sinus specimen. The isolate was Scedosporium apiosp...

Maxillary sinus mucocele can occur due to many medical factors such as chronic infection, allergic sinonasal disease, trauma, and previous surgery. However, it occurs mainly after Caldwell-Luc operation, usually more than 10 years after surgery. There are a few cases of maxillary sinus mucocele with ocular symptoms. Also, a case causing ocular symptoms because of invasion to the orbital floor i...
