Abstract
The physical symptoms of scarring such as pain, redness and itching have long been known to cause considerable distress to patient and many treatments aim to provide relief. .
Plastic surgeons play an important role in both the prevention and the treatment of unaesthetic scar formation following operations
In the past, treatment was mainly focused on severe scarring, such as the hypertrophic and burn scars.
Several nonsurgical and surgical interventions have been investigated for the treatment of scars .
Lasers could also be used before or immediately after surgery to prevent (or at least reduce) the apparition of scars .
The desired interaction of ablative LASERs is to precisely remove a thin layer for resurfacing or narrow column for fractional treatment of skin , leaving behind minimal residual thermal damage .
CO2 LASER is the most commonly used LASER for ablative skin resurfacing. This LASER light is absorbed by water-containing skin cells within top skin layers, resulting in superficial tissue vaporization with production of coagulative necrosis in the remaining dermis.
The fractional photothermolysis (FP) uses microbeams of LASER to target the tissue , including microthermal zones (MTZ) of injury, that it spares untreated skin surrounding each MTZ , allowing fast healing and reducing the risk of side effects.
In this study we used the fractional co2 LASER to improve early post-operative scars, only part was treated using the co2 fractional LASER and the other part was left as control.
Total number of patients was 20 patients. We didn’t use any local anesthetic cream except in one case which developed moderate pain sensation,
The VSS was improved by 80 % between treated and untreated parts , there was significant difference in total vss score between untreated part mean 4.8 and SD 01.9358 and treated part mean 3.00 and SD 1.2566 (p value < 0.05).
The best response was in the pliability , the difference in pliability between untreated part mean 1.7 and SD 0.8645 and treated part mean 1.00 and SD 0.5620 ( p value < 0.01 ).
Only three cases reported pain sensation which was mild in three cases and moderate in only one case which was avoided by prior application of EMLA ® cream
Regarding other complications, two cases showed hyperpigmentation one disappeared without any intervention and the other required the use of topical steroid creams.
One case showed hypopigmentation which disappeared without any intervention.
