Concentric circumareolar approach in treatment of gynecomastia

Objective To discuss the method and significance of concentric circumareolar approach in treatment of gynecomastia. Methods The incision was designed with the patient in a standing position. The lo- cation of the new nipple was determined, around which a outer cycle with the diameter of 5 cm was marked. And then a concentric inner circle with the diameter of 2. 5 - 3 cm was marked around the original nipple. The bilater- al nipple position should be on the same level. A rim of tissue around the nipple-areola complex （ NAC ） was de- epithelialized, excision of excess glandular tissue was performed subcutaneously and vascular network of dermis was preserved as much as possible. The purse string suture was applied in the circumareolar incision. Results 30 patients with gynecomastia were treated with this method. The result of the operation was pleasing with good aesthetic appearance, normal blood supply, and inconspicuous scars. Conclusion As a surgical approach of gynaecomastia, concentric circumareolar incision can remove excess glandular tissues and redundant skin, and has the benefit of concealing incision, simple procedure and satisfactory outcome.
