Intracranial extension of paranasal sinus mucocele: two case reports.

In two cases intracranial extension of mucoceles of the paranasal sinus was safely removed by intranasal evacuation and drainage of the lesions located in the paranasal sinus. The diagnosis was ascertained in both cases via intranasal approach. In addition, the volume of the intracranial lesions was reduced. This procedure is both effective and a less invasive diagnostic treatment for the lesion.
