Hilton's Method of Incision and Drainage of Abscess

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)

When I Become a Professor Someday.....

With the passage of time, I may assume different positions and designations in my life be it personal or professional. My acquaintances change, closeness to people at times may vary, some new people get connected and some may be left out somewhere along the journey. But, I might become a Professor some day. I cannot actually visualize what type of professor I am going to be. But, I know what type of Professor I do not want to become.
