Hole of the Eustachian Tube Tympanic

The orifice of the tympanic tube or tympanic foramen is an open space that connects the tympanic cavity of the middle ear to the nasal cavity. This is one of three openings through which the ear cavity is ventilated and the pressure inside the ear cavity is controlled. The tympanic tube consists of four main elements: the external auditory canal, the tympanic membrane, the intratympanic cavity, and the auricle.

The hole of the drum tube is the air inlet and outlet. It opens from the tympanic membrane to the nasal cavity and allows sound to pass into the ear cavity without difficulty. The tympanic meatus is tapered to create optimal acoustic effect and can be closed by small muscles called Eustachian valves.

When the ear canal becomes closed or blocked for any reason, the outside air pressure increases which can lead to various problems. The most common disorders associated with tympanic meatus closure include chronic ear congestion, hearing loss, and eustachian tube dysfunction. Myringitis, an inflammation of the membrane covering the ear drum caused by fluid accumulation in the inner ear and bacterial infection, may also occur.

Trouble

The opening of the auditory tube is a two-way canal between the upper parts of the nose and pharynx and the middle ear, connecting the tympanic cavity through the auditory tube with the nasal cavity. Under normal conditions, it is hermetically sealed by muscles and one of the branches of the auditory tube or a sickle
