Background: Hypertrophic scars are one of dermal fibroproliferative
disorders which can lead to pruritus, disfigurement
and pain. The use of microneedling to introduce topical agents
or drugs into the dermis is a rapidly growing and popular
skin/scar treatment.
Patients and Methods: This is a prospective randomized
study that included 30 patients suffering from Hypertrophic
scars and they are candidate for the proposed technique.
Microneedling by Dermapen device with application of topical
triamcinolone acetonide solution on scar tissue for three
sessions with 3 weeks interval in between.
Results: During one year, 30 patients were recruited in
our study, the mean age of the patients was 28.16±11.24 (range
21-58 year) and 52% of patients were female. Lesions location
were anterior chest (8), extremities (18) and back (4). Mean
zero VSS scores were achieved with triamcinolone transepidermal
injection in respect of scar height (week 15th) and
pliability (week 15th).
Conclusion: Our results did support the capability of
triamcinolone transepidermal injection using Dermapen in
treatment of hypertrophic scars, with an efficient, less painful
and cost-effective procedure.
