Can Transcutaneous Cranial Nerve Block Needle Treat Rhinitis?

Local anesthetics are injected around the nerve trunk, plexus and ganglia to block its impulse conduction and make the innervated area produce anesthetic effect, which is called nerve block. A nerve block is injected in only one place to obtain a large area of anesthesia. However, it may cause serious complications, so the operation must be familiar with the local anatomy, understand the tissue that the needle will go through, as well as the nearby blood vessels, organs and body cavity. Common nerve blocks are helpful for interorbital, suborbital, sciatic, finger (toe) nerve stem blocks, cervical plexus and brachial plexus blocks, as well as stellate ganglion and lumbar sympathetic ganglion blocks for diagnosis and treatment.
