Facial Nerve-Block Anesthesia in Cosmetic Dermatology
Sensory neural blockade of the face with local anesthetics is an important part of the management of cosmetic procedures, but it is not usually considered a simple approach. The facial sensory innervation is provided mainly by the trigeminal nerve, the largest and the most complex cranial nerve. The peripheral branches of the trigeminal nerve that may be accessible through percutaneous needle techniques are the supraorbital, supratrochlear, nasociliary, infraorbital, and mental branches. In addition to indications for general surgical anesthesia and treatment of painful clinical conditions, the local anesthetic blockade of the trigeminal nerve branches can be used to produce more patient tolerance on painful esthetics procedures, such as facial deep chemical peelings, laser, fillers, microneedling, and dermabrasion.
The main purpose of this chapter is to describe the techniques of blockade of the trigeminal nerve branches with local anesthetics by means of practical approaches, including relevant anatomical landmarks, possible complications and unwanted side effects.
