Minimal surgical technique: make a small incision about one-third the diameter of the cyst, then remove the cyst. The advantage of this technique is that it leaves a small scar, but the risk of the cyst is not completely removed, the possibility of recurrence is high. Elliptical excision: This technique is suitable for infected, ruptured or inflamed cysts that have scarred the surrounding tissue. This method has a high risk of leaving a bad scar, but it will help remove the entire cyst and surrounding affected tissue, minimizing the risk of remaining cyst wall causing recurrence. Carbon dioxide laser surgery: this is a modern technique to help evaporate the cyst, leaving little scarring.
