Underlying blood vessels or nerves may be injured while draining the abscess. So, a technique known as Hilton's method of Incision and drainage is followed to prevent the underlying nerves and blood vessels.
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)
