Post burn contracture reconstruction

Burns can be devastation injury with long lasting morbidity. Deformities secondary to burns are unfortunately uncommon in our country. These deformities in addition to being unsightly, can frequently be functionally limiting. We at Sushrutha provide treatment to primary burns as well as treatment and prevention of secondary deformities.

INTRODUCTION:

Skin being the largest organ of our body, has multiple functions and in general protects the internal organs from environmental insults. Any breach in this protective layer endangers the stability and normal functioning of the body.
Most frequent cause of burns is scalds (spillage of hot liquids), followed by flame burns. Less frequent are contact burns, frictional burns, chemical burns, electrical injury, sun burns, lighting injury. While a number of them die due to burns per se & its multi organ complications, most survivors are left with disabilities & disfigurement making their life miserable. The treatment doesn’t limit to wound management and functional recovery, but extends to emotional, psycho-social and vocational rehabilitation over a course of months or years.

A realistic approach is necessary to harmonize patient expectations with probable outcomes of surgery.

PROCEDURES:

1. EXCISION AND PRIMARY CLOSURE/ Z-PLASTY-

   One of the simplest procedures of reconstruction. It is applicable in areas w here there is no deficiency of tissue that can be mobilized to close the wound. It involves excision of the whole scar tissue and adjacent tissue is mobilized for primary closure.
   May also be done as serial excision, giving the surrounding tissue adequate to stretch. This is especially applicable in facial burns as it has the best outcome with good tissue texture and color match.

2. CONTRACTURE RELEASE AND GRAFTING-

   IIt involves excising the whole scar tissue and covering the tissue with a split or full thickness scar. It is, especially applicable over non-joint surfaces and where there is no sufficient tissue available for primary closure without compromising function.

3. SCAR EXCISION AND LOCAL FLAP COVER:

   The whole scar tissue is excised as a whole and locally available skin and soft tissue is mobilized to cover the defect. The flaps have to be strategically designed to prevent further prominent scars or pull of surrounding appendages (especially in Head, neck and face region). Also important is planning the flaps to facilitate primary closure of donor sites and hence its use may be limited to small scars.
   Advantages include best possible tissue texture and color match.

4. FREE FLAPS:

   The management of post burns scars and contractures have reached a milestone with the advent of microsurgery. Free tissue transfer offers a great option of large defects and joint contractures. Large area of scars especially over joint surfaces leading to contractures and difficulty in normal daily functioning, where there is inadequate or no locally available tissue.
   The long term prognosis is good with vascular tissue.
   The main limiting factors include- needs good microsurgical skills, longer hospital stay to assess flap vascularity, and availability of donor tissue in case of large surface burns and also morbidity of donor site.

5. TISSUE EXPANSION:

   In the face of limited availability of soft tissue cover, tissue expansion has revolutionized plastic surgery leaving the surgeon with far better prospects of reconstruction especially in burns sequelae management. While it provides skin with near perfect color and texture match, it also assures minimal donor site morbidity. The major limiting factors include cost of the implant per se and multiple procedures and serial expansion requiring the patient to come to the clinic or hospital multiple times.

6. NON-SURGICAL PROCEDURES:

   1. SPLINTS: splints are usually bulky and cumbersome. Patient compliance is a major decisive factor determining splint outcome. While minor contractures may require splinting alone, some may require surgical correction followed by splinting.
   2. FACE MASKS: for hypertrophied scars over the head, and face region with or without silicone inserts. Full time application of face masks may not be practical for most patients, however may be an option for patients who do not wish to undergo surgical procedures.
   3. SILICONE INSERTS:

RECOVERY:

Recovery from burns sequel and its management depends upon the procedure done. While primary excision and grafting or local flaps may be healed within a period of 2-3 weeks, free tissue transfer and major reconstructions require about 6weeks for full recovery. Most reconstructions, however ,require multiple procedures done at serial intervals of 6 months or more.
