Takasaki K, Takahashi H, Miyamoto I et al (2007) Measurement of angle and length of the eustachian tube on computed tomography using multiplanar reconstruction technique. It contains the bones of the middle ear, called the malleus, incus, and stapes. Any problems related to the tube or the middle and inner ear can induce. An ear tube is usually made of metal or plastic. It connects the middle ear (behind the ear drum) to the nasal cavity and upper. The tube is usually closed and opens when a person eats. This opening enables drainage of the middle ear, allows air to flow into the middle ear and prevents the buildup of fluids behind the eardrum. The Eustachian Tube (ET) is a small passage way that connects the middle ear to the nasopharynx. Seibert JW, Danner CJ (2006) Eustachian tube function and the middle ear. Ear tubes are tiny, hollow cylinders that are surgically inserted into the eardrum. 1st and 2nd pharyngeal arches give rise to the malleus, incus, and stapes. On the outside wall of the box has a large hole in it which is covered by the ear drum. In: Flint PW (ed) Cummings otolaryngology: head and neck surgery, 5th edn.
