The nerve supply to the hard and soft palate is from the greater and lesser palatine nerves passing through the sphenopalatine ganglion. The maxillary nerve (MN) provides sensory innervation of the anterior and posterior palate, the upper dental arch, the maxillary sinus, and the posterior nasal cavity. Maxillary nerve block (MNB) through the infrazygomatic route, used for the treatment of trigeminal neuralgia in adults, permits anesthesia of the entire palatine territory. However, this nerve block has led to complications such as orbital puncture, intracranial injection, maxillary artery puncture, or posterior pharyngeal wall injury.
