AbstractBackground: Scar revision continues to be a challenge to any practicing cosmetic surgeon. Rejuvenation of existing scar without revision surgery reduces the psychological stress of the patient as well as the clinician. Nano fat grafting for scar rejuvenation has gained increasing popularity because of its relative safety and has become an increasingly popular alternative to dermal fillers due to its biocompatibility. The aim of this study is to determine the aesthetic outcome of nanofat injections in scars using a standardized and validated Patients Observer scar Assessment Scale (POSAS) and photographs.
Material & Methods: This was a prospective observational study done on 50 patients who came in general surgery outpatient department with scars demanding scar revision in J.L.N. Medical College & Hospital, Ajmer, a tertiary care centre in Rajasthan, India during a period of two year from January 2020 to December 2021. Pre-operative POSAS observer scale scoring was done by the principal investigator and the patient scale scoring was done by patient under investigator’s supervision. Photographic documentation was also done for all cases.
Results: Our study showed that the mean age of all the patients which was calculated to be 43.88 ± 9.55 years. Most of the patients, i.e., 76% it had hypertrophic scar where is 14 % had flat type of scar and 10% of all the patients had atrophic type of scar. In this study it was found that 68% of patients at the scar for less than 5 years and 32% of patients had the scar for more than 5 years. Preoperatively, mean score in all the questions ranged between 5.24 and 6.02 with the mean total score being 39.56 ±3.45, whereas, mean score in all the questions postoperatively ranged between 3.5 and 4.74.
Conclusion: After undergoing the extensive research, collecting the data for the study purpose, analyzing the data, we could safely conclude that the nanofat injection was useful for the scar treatment.
