Abstract

Background:Thermalinjuries  can  lead  to  severe  hypertrophic scarring  and  be  psychologically devastating  for  patients.  Patients  often  seek  help  to  improve  aesthetic  appearance  and  function  of hypertrophic scars and contractures. This study aims to share our experience with microneedling also called “percutaneous collagen induction” of mature hypertrophic scars from thermal injuries in all ages.  Patients  and  method:This  prospective  study  includes  patients  of  all  age  groups,  deemed  suitable  for treatment of mature hypertrophic scars. Patients were excluded if they had skin infections, unrealistic outcome expectations or immature scarring. Suitable patients were instructed in pre-and post-operative treatment  with  vitamin  A  and  use  of  microneedling  (Dermaroller®).  Surgeries  were  performed  under General  Anesthesia.  Patients  were  assessed  in  outpatient  clinics  post-operatively  and  offered  further treatment if necessary. After completed treatment self-assessment forms were filled out by the patients. Results:19 patients (F:M 12:7), age 4-82 years (median 18,5). Burn mechanism was mainly flash burns or scalding. Interval from time of injury to treatment varied from 10 months –17 years. Interval from time  of  treatment  to  evaluation  ranged  from  2,5  weeks -7  months.  14  patients  reported  an  overall improvement on the self-assessment scale. 12 patients reported improvement in thickness, irregularity and colour, 10 patients in elasticity, 7 patients in pain and 8 in pruritus. 8 patients would recommend treatment  to  others.  13  patients  reported  post-operative  discomfort  (itching,  erythema,  swelling). Majority of these adverse effects resided within 3 weeks. Conclusion:Wecan  conclude  that  microneedling  is  a  safe  treatment  for  patients  suffering  scarring following thermal injuries. Results may vary but no harmful side effects were recorded. Further studies are  needed  to  improve  objective  outcome  measurements,  as  this  proved  to  be  the  most  challenging factor in the study.
