Sinus anatomy, computer illustration. The sinuses are membrane-lined air-filled spaces in the bones of the face. The frontal sinuses are above the eyes. Below these are the many lobed ethmoid sinuses and behind them the sphenoid sinuses. Either side of the nose are the maxillary sinuses. The sinuses are lined with mucus, which drains into the nasal passage. | |
