ENT · Nose and paranasal sinuses: periodicity of sinus headache
Sample itemA patient's headache starts on waking in the morning, is felt over the forehead and eases through the afternoon. Which sinus is most likely involved?

Correct. Morning forehead pain is classically frontal.

Maxillary pain is felt in the cheek and peaks later.
