Abstract
Due to the prevalence of acne scarring and the emotional distress it causes to those affected, dermatologists are likely to be presented with the challenge of evaluating and managing patients with atrophic acne scars (Fife, 2011).
Success in the management of the acne scar patient hinges on the physician’s clear understanding of the patient’s goals for treatment, ability to tolerate downtime and pain, time constraints, and financial constraints (Fife, 2011).
Various therapeutic options have been described with variable clinical outcomes and complications (Kim et al., 2009).
Whatever the choice, it should be clearly understood by both physician and patient that, at present, improvement of acne scarring, rather than total cure, is the ultimate goal (Rivera, 2008).
Subcision is a simple procedure for revision of acne scars. Any area on the face can be treated in minutes with an inexpensive specialized needle. Treated scars can become substantially less noticeable. Improved but somewhat persistent scars can be subcised again or further smoothed by a resurfacing technique, such as laser resurfacing. (Branson, 1998).
Suction is a complementary treatment to subcision that can be done after subcision in depressed and flat scars. It was hypothesized that, repeated suctioning of the subcised scars might prevent re-depression by induction of repeated haemorrhage in the dermal pocket, delay in healing and more new connective tissue formation at the scar area. (Harandi et al., 2011).
