Modelling of Audio-visio-Tactile (AVT) Machine

In some dermatologic and cosmetic procedures, local anesthesia is not sufficient for relieving pain and also patients are often are averse to injections. We propose vibration anesthesia, the use of vibration delivered with commercially available inexpensive massagers to reduce discomfort. We find the analgesic effect of vibration helpful in minimizing pain in patients undergoing injections of botulinum toxin type, a treatment for hyperhidrosis, injection of filler substances such as Rest lane and Juvederm, laser therapy for leg veins, nail-fold injections, Q-switched laser treatment of tattoos, incision and drainage of abscesses, and cautery of facial warts. We expect that additional uses will be found in future. Although the use of vibration anesthesia generally does not eliminate pain completely, it can serve to make the injection or procedure much more tolerable.
