Sphenopalatine vacuities

Sphenopalatine vacuities are a pair of small spaces located in the sphenoid bone of the human skull. They are also known as the sphenopalatine sinuses and are part of the paranasal sinuses system.

Anatomy

The sphenopalatine vacuities are located in the body of the sphenoid bone, behind the nasal cavity and below the sphenoid sinus. They are separated from each other by a thin, bony septum. Each vacuity communicates with the nasal cavity through the sphenopalatine foramen.

Function

The primary function of the sphenopalatine vacuities, like other paranasal sinuses, is to produce mucus that moisturizes the inside of the nose. This mucus layer protects the nose from pollutants, micro-organisms, dust, and dirt. Sinuses also play a role in our voice's tone.

Clinical significance

Inflammation of the sphenopalatine vacuities, often due to infection, can lead to a condition known as sphenopalatine sinusitis. This condition can cause symptoms such as headache, facial pain, and nasal congestion. Treatment typically involves antibiotics, nasal decongestants, and in severe cases, surgery may be required.
