Dermatologists who master the use of facial nerve blocks can make nonsurgical procedures more comfortable for patients, according to Dr. Howard K. The concept of "nonsurgical" cosmetic procedures creates an expectation that the procedures may be painless, said Dr.
The efficacy of different techniques of facial nerve block for cataract surgery was investigated. Forty four patients underwent either modified O'Brien, Atkinson, van Lint, or lid blocks. Intentional muscle activity of the orbicularis oculi muscle was recorded and the area under the EMG curve calculated for quantitative comparison of muscle activity between the groups before and after injection of lignocaine with the vasoconstrictor naphazoline nitrate.
A new study has shown that use of peripheral nerve blocks in the treatment of Trigeminal Neuralgia TGN may produce long-term pain relief. TGN is a condition involving sudden episodes of severe facial pain that significantly reduces quality of life in those affected. When medication fails to control the pain, some patients turn to invasive procedures that require a high level of expertise and can result in long-standing numbness.

Current Dermatology Reports. Peripheral nerve blocks represent an invaluable tool for dermatologic surgeons. Specifically, blockade of the supraorbital and supratrochlear, infraorbital, or mental nerves provides adequate anesthesia to a large area with minimal discomfort to the patient.
A trigeminal nerve block is an injection of medication that helps relieve facial pain. Trigeminal nerves are responsible for sensations in your face and for helping you bite, chew and swallow. Blocking these nerves can help you stop feeling facial pain.
Ophthalmology and Visual Sciences. Addition of 0. The following diagrams illustrate common local nerve blocks used in ophthalmology.
The buccal nerve long buccal nerve is a nerve in the face. It is a branch of the mandibular nerve which is itself a branch of the trigeminal nerve and transmits sensory information from skin over the buccal membrane in general, the cheek and from the second and third molar teeth. Not to be confused with the buccal branch of the facial nerve which transmits motor information to the buccinator muscle. It courses between the two heads of the lateral pterygoid muscleunderneath the tendon of the temporalis muscleand then under the masseter muscle to connect with the buccal branches of the facial nerve on the surface of the buccinator muscle.
Peripheral facial nerve palsy FNP is a common neuropathy of cranial nerves. However, it is a rare condition in dental treatment and may be associated with local anesthetic injections. Initial trauma to facial nerve cab is usually minor.
