Subsequent magnetic resonance imaging (MRI) identified an enhancing mass involving the left subfrontal
area of the brain with contiguous involvement of the left ethmoid air cell and intracranial extension (figure 1).
Males had eroded spots on the subfrontal
area of the prosoma and claspers, which result from amplexus.
MRI studies of civilians with posttraumatic anosmia demonstrated damage to the olfactory bulbs and tracts, subfrontal
cortex, and temporal lobes [77-78].
During the surgical procedure the brain was visualized to be swollen and the subfrontal
regions severely contused.
Although some authors suggest craniotomy, either from a pterional or subfrontal
approach, or cystoperitoneal or ventriculoperitoneal shunting, most surgeons with experience using the transsphenoidal approach favor the latter as the most direct and least invasive method of decompressing and fenestrating the cyst.
Specifically, suprasellar lesions can be approached through a subfrontal
or pterional (fronto-temporal) approach.
