The first step in ear harvesting is to understand the structure of the ear, which is divided into three parts: the outer ear, the middle ear and the inner ear.
External ear: Including auricle and external auditory canal. The shape of the auricle is conducive to the gathering of sound energy, the collection of sound, and the location of sound sources.
Middle ear: It is mainly located in the petrous part of temporal bone, including tympanic chamber, eustachian tube, tympanic sinus, mastoid process and mastoid chamber.
Inner ear: Complex structure, also known as labyrinth, all buried in the petrous bone of the temporal bone, between the tympanic chamber and the bottom of the inner ear canal, consisting of bone labyrinth and membranous labyrinth.
In the second part, we need to know the types of ears, which can be divided into four types: cauliflower ear, hidden ear, windbreaker ear and cup ear.
Cauliflower ear: Cauliflower ear, which makes cartilage contracture thicker and more deformed, curls up and has irregular shape, is called cauliflower ear.
Saphenous ear: Saphenous ear, also known as baggy ear, is a rare congenital ear deformity. It is characterized by a combination of the anterior ear skin and the cranial skin except for the normal earlobe, and the normal cartilage structure of the auricle, which is buried in the skin but not normally prominent, is called the saphenous ear.
Wind-inspiring ear: Wind-inspiring ear is a common congenital ear deformity, mostly bilateral. It is characterized by a slightly larger auricle, flat upper part, hypoplasia of the earring and disappearance of its shape; and over-development of the ear concha with an angle greater than 150 degrees (normal 90 degrees) between the ear concha and the ear concha is called the windbreaking ear.
Cup ear: Cup ear, also known as curly ear or lobe ear, is a common congenital ear deformity, mostly occurring on both sides. It is characterized by tightening ear rim, curling and adhesion of ear wheel and auricle cartilage, narrow scaphoid and triangular fossa, narrowing and drooping of the whole upper part of the auricle in severe cases, disappearance of the shape of the scaphoid and the pair of ear wheels, and tubular whole auricle is called cup ear.
Before ear harvesting, let the recipient take a comfortable position or sit or lie down. The head is tilted to one side and the light should be sufficient.
