The nasal sinuses are air-filled chambers within the bones of our face that drain into the nasal cavity. The sinuses are lined by mucosa, which is a thin lining that secretes mucus. There are four paired sinuses, named according to the bones in which they lie. They develop prenatally as well during childhood, so an adult’s sinus anatomy can be quite different from a child’s.
The sinuses are an essential part of the immune system and also help to filter the air we breathe. The mucus secreted by the sinuses moisturizes the nasal cavity but also helps to trap viruses, bacteria, and particulates from the air. Nasal mucus contains antibodies and other immune factors that help the body fight infection. The mucosal lining at a microscopic level also has tiny hair-like structures called cilia that beat and direct the flow of mucus out of the nasal cavity.
The Maxillary Sinuses
The maxillary sinuses are large single-chambered sinuses existing below the eye and in the cheek. Inflammation or infection in this sinus can cause sensations of cheek pressure or discomfort in the upper teeth. The maxillary sinuses are present at birth and expand as the face develops during childhood development.
The Ethmoid Sinuses
The ethmoid sinuses are a honey-comb like complex of sinuses located between the eyes. Inflammation and infection in these sinuses can cause pressure in or between the eyes. The ethmoid sinuses are also present at birth and continue development through childhood.
The Frontal Sinuses
The frontal sinuses are paired sinuses located in the bone beneath the forehead and above the eyes. Inflammation or infection in these sinuses often causes forehead pain or pressure. The frontal sinuses are not present at birth and only start development around 6-8 years old and finish growing during adolescence or early adulthood.
The Sphenoid Sinuses
The sphenoid sinuses are the deepest most sinuses, located at the center of the skull. Many important structures are located around the sphenoid sinuses including the optic nerves, carotid arteries, and the pituitary gland. Inflammation or infection in the sphenoid sinuses may cause pain or pressure behind the eyes or sometimes at the top of the head. The sphenoid sinuses are also the doorway through which certain skull base tumors may be removed via an endoscopic approach.
