Can Percutaneous Cranial Nerve Block Treat Rhinitis?

Nerve block is the injection of local anesthetic around the nerve trunk, plexus and node to block its impulse conduction and produce anesthetic effect in the area it innervates. A large area of anesthesia can be obtained with a single injection of a nerve block. However, there is a possibility of serious complications, so it is necessary to be familiar with local anatomy during operation, to understand the tissues that the needle will pass through, as well as the nearby blood vessels, organs and body cavities. Common nerve blocks such as interorbital, suborbital, sciatic and digital nerve blocks, cervical and brachial nerve plexus blocks, stellate ganglion block and lumbar sympathetic ganglion block are used for diagnosis and treatment.
