Pseudocyst of the auricle, also known as auricular pseudocyst, endochondral pseudocyst, cystic chondromalacia, intracartilaginous auricular seroma cyst, and benign idiopathic cystic chondromalacia, [1] is a cutaneous condition characterized by a fluctuant, tense, noninflammatory swelling on the upper half of the ear, known as the auricle or pinna.
Hearing loss is often secondary to absent, small or unusually formed ears and commonly results from malformations of the middle ear. Researchers have found that most patients with Treacher Collins syndrome have symmetric external ear canal abnormalities and symmetrically dysmorphic or absent ossicles in the middle ear space.
Ear anomalies include extra openings in front of the ears, extra pieces of skin in front of the ears (preauricular tags), or further malformation or absence of the outer ear . Malformation or absence of the middle ear is also possible, individuals can have mild to profound hearing loss.

TBS patients may have the following symptoms: [3] Abnormalities of the external ears (unusually large or small, unusually shaped, sometimes with sensorineural hearing loss or deafness due to lesions or dysfunctions of part of the internal ear or its nerve tracts and centers or conductive hearing loss from the external or middle ear), dysplastic ears, lop ear (over-folded ear helix ...
Each involves the external ear. The difference between them is that a cyst does not connect with the skin, but a sinus does. [ 3 ] Frequency of preauricular sinus differs depending the population: 0.1–0.9% in the US, 0.9% in the UK, and 4–10% in Asia and parts of Africa.
Microtia is a congenital deformity where the auricle (external ear) is underdeveloped. A completely undeveloped auricle is referred to as anotia.Because microtia and anotia have the same origin, it can be referred to as microtia-anotia. [1]
Ear hair generally refers to the terminal hair arising from follicles inside the external auditory meatus in humans. [2] In its broader sense, ear hair may also include the fine vellus hair covering much of the ear, particularly at the prominent parts of the anterior ear, or even the abnormal hair growth as seen in hypertrichosis and hirsutism.
