If skin cover is needed, a skin graft can be placed over top of it. Examples: gastrocnemius flap, latissimus dorsi flap, TRAM flap, and transverse upper gracillis flap. [2] Bone flaps contain bone and are used when structural support is needed such as in jaw reconstruction. Example: fibula flap. [2] [4] [14]
The term most commonly refers to a surface trauma where all layers of the skin have been torn away, exposing the underlying structures (i.e., subcutaneous tissue, muscle, tendons, or bone). This is similar to an abrasion but more severe, as body parts such as an eyelid or an ear can be partially or fully detached from the body.
Canaloplasty, where the ear canal is widened using grafts, was first proposed as the treatment for keratois obturans. However, with the migration of keratin within the canal, any amount of widening could not restore the migration of skin. Reconstruction of the bony canal with cartilage graft from temporalis fascia has showed some results. [6]
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.
However, autologous bone pieces may be unavailable or unsuitable in certain occasions. The body size of children may be not enough to have bone flaps to be stored in their subcutaneous spaces, while cryopreservation facilities for bone grafts are not widely available. [11] [12] The use of autograft is also associated with a high rate of bone ...
A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. [1] [2] Wounds can either be the sudden result of direct trauma (mechanical, thermal, chemical), or can develop slowly over time due to underlying disease processes such as diabetes mellitus, venous/arterial insufficiency, or immunologic disease.

The osteocutaneous ligaments, the zygomatic ligament and the mandibular ligament, are more important. They attach to the skin and bone, leading to a counteraction of gravitational forces. These ligaments should be released surgically to obtain a fully mobile facelift flap. Nasolabial folds; Melolabial folds (marionette lines) Greater auricular ...
