Subcision surgery for the correction of ear deformities

Subcision: Indications, adverse reactions, and pearls

BACKGROUND

Subcision, also known as subcutaneous incisionless surgery, is a surgical intervention used to treat a variety of skin conditions including atrophic acne scars, depressed scars, cellulite, and wrinkles.

AIMS

We plan to prepare a review article about the indications of subcision, its adverse reactions, and pearls.

PATIENTS/METHODS

We searched the literature for the information about subcision and its applications from papers published up to March 2019. The search was performed through the databases of the National Library of Medicine.

RESULTS

After a thorough review of the published papers about subcision, we finally chose to review 40 articles that had proper sample size and design to prepare this review article. Twenty-one papers were related to the application of subcision in the treatment of acne scar and other scars. Four articles were about the application of subcision to treat cellulite, and eight articles were related to other applications of subcision such as the treatment of striae or nasolabial fold. The remaining seven articles include published review papers about subcision or acne scar classification.

CONCLUSION

Subcision seems to be effective on various skin conditions including acne scar, other depressed scars, and cellulite. It is easy to apply and inexpensive with short downtime and no significant complications. Subcision needs proper technique and adequate experience.

Comparing cannula-based subcision with the common needle method: A clinical trial

OF TRIAL DESIGN

Treatment of depressed acne scars requires multiple modalities. Although needle subcision is a valuable method, it exhibits mild to moderate efficacy in treatment of deep acne scars owing to the high recurrence rate and other side effects. A total of 100 patients with rolling acne scars were randomly treated using the standard technique of 18 gauge cannula and 27 gauge needle subcision in two parallel groups, and the effect of cannula subcision instead of needle subcision was evaluated in the treatment of rolling acne scars.

METHODS

A total of 100 patients were randomly treated using the standard technique of 18 gauge cannula and 27 gauge needle subcision. The outcomes of these procedures were assessed by three blinded dermatologists and by patients' satisfaction.

RESULTS

Subcision using the cannula showed good and very good improvement in about 83% of patients (n = 50, P < .05) based on dermatologists investigation and almost no side effects were observed in compared with needle subcision. The response rate was significantly different while using cannula subcision.

CONCLUSION

Cannula subcision appears to be a safe and practical technique that can enhance the efficacy of subcision without considerable complications.
