Sinus Anatomy Drainage

There are three ethmoidal sinuses. The two frontal sinuses drain through the frontonasal duct which opens in the lateral wall of the nasal cavity at the semilunar hiatus 2.

Paranasal Sinus Definition Location Anatomy Function

The frontal sinus drainage pathway and related structures.

Sinus anatomy drainage. Most of the sinuses drain into the nose through a small channel or drainage pathway that doctors call the middle meatus. Anterior middle and posterior. Carried out by the anterior jugular veins.

Drained by veins synonymous with the arteries of the face and scalp. These empty into the internal and external jugular veins. Supplied by the dural venous sinuses.

A thin wall called the septum divides the nose. Venous drainage of the neck. Normally these structures help humidify and filter air.

Venous drainage of the brain and meninges. Their drainage path may vary depending on how the frontal sinus drainage pathway fsdp develops 12. The relationships of this sinus are of clinical importance the pituitary gland can be surgically accessed via passing through the nasal roof into the sphenoid sinus and through the sphenoid bone.

The inside of the nose has ridges called turbinates. They empty into the nasal cavity at different places. A person with a sinus infection often has nasal congestion with thick nasal secretions fever and cough webmd.

Patients can be treated by reducing the swelling or inflammation in the nasal passages and sinuses eliminating the infection promoting drainage from the sinuses and maintaining open sinuses webmd. Venous drainage of the scalp and face. The sphenoid sinuses drain out onto the roof of the nasal cavity.

The inferior compartment of the fsdp is formed by the ethmoid infundibulum when the superior portion of the uncinate process attaches to the skull base but is formed instead by the middle meatus when the uncinate process attaches to the lamina papyracea.
