Ethmoid Sinus
The Ethmoid Sinus is one of the four pairs of paranasal sinuses that are directly connected with the nasal cavity. It is located between the eye socket and the upper part of the nose, separated from the frontal sinus above and the maxillary sinus below.
Anatomy[edit | edit source]
The ethmoid sinus is not a single large air pocket, but a collection of 3 to 18 small air cells that are divided into anterior, middle, and posterior groups. These cells are separated by thin bony walls called septae. The ethmoid sinus is unique in that it is present at birth, and continues to grow until adolescence.
Function[edit | edit source]
The primary function of the ethmoid sinus, like other paranasal sinuses, is to produce mucus that moisturizes the inside of the nose. This mucus layer protects the nose and the respiratory tract from foreign particles that might be inhaled, such as dust, pollutants, and microorganisms.
Clinical Significance[edit | edit source]
Inflammation of the ethmoid sinus, known as ethmoiditis, is a common condition that can cause pain, swelling, and tenderness around the eyes and nose. This condition is often associated with other sinus infections, such as sinusitis. Treatment typically involves antibiotics, nasal decongestants, and sometimes surgery.
