摘要

A frontocutaneous fistula secondary to chronic frontal sinusitis can present with a fistulous opening in the forehead or in the eyelid. It may or may not be associated with Pott's puffy tumor. In this article, we present 2 cases. A case of frontocutaenous fistula with opening in the upper eyelid at the lateral portion of floor of frontal sinus and another case of chronic frontal sinusitis with sub-periosteal abscess in the forehead on the right side near the eyebrow. Relevant literature has also been reviewed.
