Steps for incision and drainage:
1. First, topical anesthesia is achieved with the help of Ethyl Chloride spray.
2. Then, a stab incision is given over a point of maximum fluctuation in the most dependent area along the skin creases, through the skin and subcutaneous tissue
3. If pus cannot be seen, the surgical site is further deepened with Lister's sinus forceps to avoid the damage to underlying vital structures (vessels and nerves)
