Ethmoid Sinus

The ethmoid sinus is a group of small air-filled cavities located within the bone between your nose and eyes. These sinuses are part of the larger sinus system and help lightening the skull, humidifying and warming the air you breathe, and enhancing your voice. They are connected to the nasal cavity through tiny drainage pathways. Because of their location, issues like infections or allergies can cause facial pain, pressure around the eyes, nasal congestion, or headaches. Proper functioning of the ethmoid sinuses is essential for healthy nasal and respiratory function.
