Summary
Local anesthesia can be done by field blocks, ring blocks, or localized nerve blocks. Nerve blocks can be used alone or in combination with other forms of anesthesia. Benefits of nerve blocks are the following: longer-lasting anesthesia; more effective anesthesia when field or ring blocks fail; less volume of local anesthesia needed, making procedure safer; and less of a painful anesthetic experience. Not all areas lend themselves to easy nerve blocks. The area being treated must be within a zone fed by a specific nerve. One must have an understanding of sensory enervation and anatomy of different nerves. Care must be taken not to damage the nerve with intraneural injection. In hair transplantation, supraorbital and trochlear nerve blocks for the frontal part of the scalp are common and consistently effective. Occipital nerve blocks for anesthetizing the occipital scalp can be used but are not consistent and therefore used less frequently. For transplants of beard and mustaches, some use submental nerve blocks, but it has to be used in combination with ring or field blocks because it does not usually cover the entire area being transplanted.
