ACNE SURGERY This modality, used for the removal of comedones and superficial pustules, aids in bringing about involution of individual acne lesions. Acne surgery was a mainstay of therapy in the past. However, with the advent of comedolytic agents such as topical vitamin A acid, it is not needed as often. Its use is primarily restricted to those patients who do not respond to comedolytic agents. Even in those patients, the comedones are removed with greater ease and less trauma if the patient is treated first with topical vitamin A acid or a similar topical agent for 3 to 4 weeks. This pretreatment should be done in all patients who are going to undergo mechanical comedo removal. Acne surgery is helpful only when properly done, and inaccurate placement of the comedo extractor may serve only to push the inflammatory material further into the skin. Therefore, it is inadvisable to have the patient do acne surgery at home. The Unna type of comedo extractor, which has a broad flat plate and no narrow sharp edges, is preferable. The removal of open comedones does not materially influence the course of the disease because these lesions do not become inflammatory. However, it is desirable to remove them for cosmetic purposes. In contrast, closed comedones should be removed to prevent their rupture. Unfortunately, the orifice of closed comedones is often very small, and usually the material contained within the comedo can be removed only after the orifice is gently enlarged with a no. 25 needle or other suitable sharply pointed instrument.
INTRALESIONAL GLUCOCORTICOIDS Intralesional injection of glucocorticoids, either by the use of a syringe or by the use of an automatic needleless injector, usually dramatically decreases the size of deep nodular lesions. The injection of 0.05 to 0.25 mL per lesion of a triamcinolone acetate suspension (2.5 to 10 mg/mL) is recommended as the anti-inflammatory agent. This is a very useful form of therapy in the patient with nodular acne, but it often has to be repeated every 2 to 3 weeks. A major advantage is that it can be done without incising or draining the lesions, thus avoiding the possibility of scar formation.
