Sphenoid And Sellar Tumors

Myxoma of the Sphenoidal Sinus

“…The cells of the latter tumors should appear differentiated. 3 The symptoms of head and neck myxomas are painless swelling in the affected region and nasal obstruction when the tumor arises in the sinonasal tract, as in our case. High-resolution CT reveals bone destruction and clearly outlines the tumor margins.…”

“…Benign lesions that arise in the sphenoidal sinus are papillomas, adenomas, osteomas, ossifying fibromas, chondromas, chordomas, giant cell tumors, hemangiomas, and neurinomas. The cells of the latter tumors should appear differentiated 3 …”

Minimally Invasive Approaches to the Sphenoid Sinus

“…The transseptal, transsphenoidal approach is a safe, rapid, and direct route to the sella. 2 Further, these patients are often referred for this procedure from neurosurgeons, who prefer this approach for its exposure and accessibility to microsurgical instrumentation. Such is the case at our institution.…”

“…A 37-year review of isolated sphenoid sinus lesions from the Mayo Clinic found only 6 primary malignancies. 2 Fibro-osseous lesions, notably fibrous dysplasia and ossifying fibroma, although rare, must also be considered. Lesions of the sella turcica and parasellar region are predominantly intracranial and usually treated by neurosurgeons.…”

“…The differential diagnosis of sphenoid sinus pathology is diverse, but dominated by infectious and inflammatory processes such as rhinosinusitis and polyposis. A 37‐year review of isolated sphenoid sinus lesions from the Mayo Clinic found only 6 primary malignancies 2 . Fibro‐osseous lesions, notably fibrous dysplasia and ossifying fibroma, although rare, must also be considered.…”
