   Problem Faced Top


Intradermal injections in the scalp are often painful, and it is a challenge to obliviate the pain factor. Various methods of anesthesia for the scalp have been used, such as regional nerve blocks, infiltration anesthesia, and topical anesthetic creams. Each of these methods has its inherent drawbacks. Regional blocks and infiltration anesthesia need a certain level of skill to perform and topical anesthetic creams are messy, take a long time to act on the scalp, and are often ineffective.[1] Cooling and vibration are other methods, which have a limited efficacy and need additional devices.


   Solution Proposed Top


We used a sterile comedone extractor [Figure 1]A, which is a simple and readily available instrument in dermatology clinics, as a device to alleviate pain during scalp injections. The instrument was pressed on the scalp, and injections with an insulin syringe with a 30-32G needle were administered through the head (loop) of the extractor [Figure 1]B, Video 1]. This provided a dual benefit of significant anesthesia via the pain gate theory,[2] as well as hemostasis. According to the pain gate theory, pain perception is reduced by the perception of pressure by the instrument. The rim of the loop provides hemostasis, pressure anesthesia, and a window for injections. The familiarity with the instrument and ease of use are added advantages. This technique provides a neat and effective method of inducing anesthesia for scalp injections.

Platelet-rich plasma (PRP) is injected through the loop with an insulin syringe (32G needle) while maintaining the pressure at comedone extractor
