Spindle cell carcinoma (SpCC) is a rare variant of squamous cell carcinoma (SCC). SpCC of sinonasal origin is relatively rare and more aggressive than normal SCC. It most commonly involves the maxillary sinus, and rarely the sphenoid sinus. The present study reports a case of sphenoid sinus SpCC presenting with bilateral visual loss. Following endoscopic sinus decompression surgery, the patient...

Mucocele is a benign pseudo-cyst formation that rarely develops in the maxillary sinus. Mucocele is secondary to various conditions having in common an inflammation and an obstruction of the sinus ostium. The latter may be primary but it is often secondary to a trauma, tumor, chronic inflammation. Diagnosis is based on imaging. CT scan is essential for assessing osseous changes and for planning...

Background and Purpose Sphenoid bone fractures and sphenoid sinus fractures have a high morbidity due to its association with high-energy trauma. The purpose of this study is to describe individuals with traumatic injuries from different mechanisms and attempt to determine if there is any relationship between various isolated or combined fractures of facial skeleton and sphenoid bone and spheno...

Giant mucoceles of the frontal sinus are rare but their recognition is important in the differential diagnosis of proptosis and fronto-orbital lesions. The authors describe a patient with frontal giant mucocele with intracranial as well as orbit and ethmoid sinus involvement. Thirty-two years after a frontal sinus fracture, a 51-year-old female presented with headache, and left exophthalmos and...

OBJECTIVE To report 3 cases of pneumosinus dilatans of the sphenoid sinus associated with visual loss. MATERIALS AND METHODS Retrospective case series describing history of visual loss, visual examination, visual field deficits, and radiologic imaging. RESULTS Three patients developed visual loss associated with pneumosinus dilatans of the sphenoid sinus. CONCLUSIONS Pneumosinus dilatans ...

Bilateral paranasal sinus mucoceles are rare. To date, only 5 cases have been reported in the English-language literature. All were bilaterally symmetrical. We present a patient with bilateral asymmetric mucoceles. This patient had a symptomatic mucocele of the right ethmoid sinus with orbital extension and an asymptomatic mucocele involving the left maxillary sinus with retroorbital extension....

Ten percutaneous transnasal sphenoidotomies were performed in nine children; and in seven, a sphenoid window was also created. All procedures were performed in the special procedures laboratory, with biplane fluoroscopic guidance used in each case. Under general anesthesia, with the child in the supine position, a 14-gauge antral trocar was placed transnasally into the sphenoid sinus. The sinus...

Primary inverted papilloma of the sphenoid sinus is rare. Such a case, of a 42-year-old female, is reported here, discussing the clinical presentation, diagnostic clues, radiographic features, histological findings and management. In contrast to the vast majority of cases that present with nasal complaints because of lateral nasal wall involvement, the clinical presentation of inverted papillom...

The aim of this study was to analyze the bacterial flora in the nasal cavity and sphenoid sinus and evaluate the sensitivity of these bacteria to antibiotics that can be used to prevent postoperative meningitis. Bacteria of the preoperative nasal cavity and intraoperative sphenoid sinus mucosa were cultured and analyzed in 40 patients (20 men and 20 women; mean age, 52.2 years) who underwent en...
