CS L 13 Reconstructive Surgery⭐

reconstructive surgery

repairs or replaces skin that as been damaged

common reasons for reconstructive surgery

wounds, neoplasia, developmental disease

3 phases of wound healing

1. Inflam

2. Cellular proliferation/ granulation (fibroplasia, angiogenesis, epithelialization)

3.remodeling/ maturation (contraction and reorganization)

how to optimize wound healing

aseptic handling and equipment

suitable lavage

thorough debridement

correct bandaging

good nutrition

analgesia

what effect does cutaneous muscle have on healing

better when present as blood supply is better

cutaneous muscle is thick on thoracic skin and absent on limbs

types of reconstructive surgery techniques

>special closure techniques

>skin flaps

>skin grafts

what are the special closure techniques

> cosmetic closure of skin defects

> tension relieving and skin mobilization procedures

examples of tension relieving and skin mobilization procedures

far-near-near-far sutures

stents

undermining skin (create small secondary wound near to sutures)

mesh expansion

what is a skin flap

living tissue deprived of original blood supply and transerred to new site

autograft/ iosgraft

same individual

allograft/ homograft

same species

xenograft/ heterograft

another species

full thickness graft

includes epidermis and entire dermis

split thickness graft

epidermis and portion of dermis (more succesful)

mesh graft

A skin graft that is altered to create a mesh-like pattern in order to cover a larger surface area

island grafts

small pieces of skin implanted into large field of open granulation tissue: rely on keratinocytes that proliferate and migrate from edge of islands to cover site

Pinch (split thickness)

Punch (full thickness)

Strip
