"A New Injection Method of Nerve Block Combined with Local Infiltration Anesthesia for Relieving Pain of Horizontal Neck Lines Injection".

ABSTRACT

SUMMARY: Filler injection is one of the effective methods for the treatment of horizontal neck lines, but the pain caused by injection has become a huge burden for many patients both physically and mentally. Topical anesthesia and local refrigeration are common methods to relieve the pain of injection, but each has its disadvantages. The transverse cervical nerve is the main innervating nerve for pain sensation in the anterior skin of the neck. In this study, we performed nerve block anesthesia and local infiltration anesthesia on one side of the horizontal neck lines and applied topical anesthesia cream on the other side of the neck among 100 patients. The results showed that the pain patients suffered under nerve block anesthesia and local infiltration anesthesia was reduced by 81% compared with that of patients using the topical anesthesia on their neck lines. And such anesthetic technique had multiple benefits, for example, it won't affect surgeon's judgment on patient's neck line shape and helps shorten the treatment time for patients. Therefore, it can be used as a new method to relieve the pain of patients undergoing horizontal neck line injection.
