Answer

Osteomyelitis is a potential local complication most commonly occurring with frontal sinusitis. Osteomyelitis of the frontal bone is called a Pott puffy tumor and represents a subperiosteal abscess with local edema anterior to the frontal sinus. This can advance to form a fistula to the upper lid with sequestration of necrotic bone.
