A single lesion on the front part of the ear is usually the initial sign of pseudocyst of the auricle. Pseudocysts of the auricle appear as flesh-colored, nontender, noninflammatory cystic lesions and progress gradually over a 4- to 12-week period. Their diameters range from 1 to 5 cm. Usually, the lesions start off soft and get firmer with time.
Newborn baby immediately after birth, covered in vernix Vernix caseosa , also known as vernix , is the waxy white substance found coating the skin of newborn human babies . [ 1 ] It is produced by dedicated cells and is thought to have some protective roles during fetal development and for a few hours after birth.
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
[1] Those requiring myringotomy usually have an obstructed or dysfunctional eustachian tube that is unable to perform drainage or ventilation in its usual fashion. Before the invention of antibiotics, myringotomy without tube placement was also used as a major treatment of severe acute otitis media (middle ear infection). [1]
Granulation tissue is new connective tissue and microscopic blood vessels that form on the surfaces of a wound during the healing process. [1] Granulation tissue typically grows from the base of a wound and is able to fill wounds of almost any size. Examples of granulation tissue can be seen in pyogenic granulomas and pulp polyps.

In 2008, in full thickness wounds over 3mm, it was found that a wound needed a material [clarify] inserted in order to induce full tissue regeneration. [ 9 ] [ 10 ] Whereas 3rd degree burns heal slowly by scarring, in 2016 it was known that full thickness fractional photothermolysis holes heal without scarring. [ 1 ]
