The veins of the tympanic region, or tympanic veins, also known as the veins of the internal mastoid process, are a venous drainage system located inside the external auditory canal and separating it from the middle ear.
The veins in the tympanic area serve to deliver venous blood from the outer ear to the general circulation system, as well as to drain inflammatory and infectious secretions from the middle ear after otitis media. This vascular device protects the middle ear from infection
