Microtia ear reconstruction

This ear reconstruction video shows a surgery to correct microtia by Toronto Plastic surgeon, Leila Kasrai MD. Microtia means small ear, and it is a congenital abnormality which causes problems with the formation of the ear tissue. In some children, a small portion of tissue is seen where the ear would normally be found. In others, the ear lobe or hollow of the ear, may be partially formed with the rest of the ear tissue missing. The most severe form of this condition leaves almost no ear tissue visible.

Keloids Pictures and Therapy

A Keloid is a type of scar with mainly type I and some type III collagen which results in an overgrowth of tissue at the site of a healed skin injury. Keloids are firm, rubbery lesions or shiny, fibrous nodules, and can vary from pink to flesh-colored or red to dark brown in color. A keloid scar is benign, non-contagious, and usually accompanied by severe itchiness, sharp pains, and changes in texture. In severe cases, it can affect movement of skin.

You should not be confused with hypertrophic scars,Hypertrophic scars remain limited to the traumatized area and regress spontaneously within 12-24 months, although regression may not necessarily be complete.

Prevention:
It is the first line in keloid therapy. Avoid performing nonessential cosmetic surgery in patients known to form keloids; however, the risk is lower among patients who have only earlobe lesions. Close all surgical wounds with minimal tension. Incisions should not cross joint spaces. Avoid making midchest incisions, and ensure that incisions follow skin creases whenever possible.


Treatments:
*Occlusive dressings include silicone gel sheets and dressings, nonsilicone occlusive sheets, and Cordran tape. These measures have been used with varied success. Antikeloidal effects appear to result from a combination of occlusion and hydration, rather than from an effect of the silicone.

*Compression therapy involves pressure, which has long been known to have thinning effects on skin. Reduction in the cohesiveness of collagen fibers in pressure-treated hypertrophic scars has been demonstrated by electron microscopy.

- Compression treatments include button compression, pressure earrings, ACE bandages, elastic adhesive bandages, compression wraps, spandex or elastane (Lycra) bandages, and support bandages. In one study, button compression (2 buttons sandwiching the earlobe applied after keloid excision) prevented recurrence during 8 months to 4 years of follow-up observation.

*Corticosteroids, specifically intralesional corticosteroid injections, have been the mainstay of treatment. Corticosteroids reduce excessive scarring by reducing collagen synthesis, altering glucosaminoglycan synthesis, and reducing production of inflammatory mediators and fibroblast proliferation during wound healing. The most commonly used corticosteroid is triamcinolone acetonide (TAC) in concentrations of 10-40 mg/mL administered intralesionally with a 25- to 27-gauge needle at 4- to 6-week intervals.

Recent innovations:
New treatments for keloids and hypertrophic scars include intralesional IFN; 5-FU; doxorubicin; bleomycin; verapamil; retinoic acid; imiquimod 5% cream; tacrolimus; tamoxifen; botulinum toxin; TGF-beta3; rhIL-10; VEGF inhibitors; etanercept; manose-6-phosphate inhibitors; etanercept; onion extract; the combination of hydrocortisone, silicon, and vitamin E; PDT; intense pulsed light (IPL); UVA-1; and narrowband UVB.
