The palatine foramen is often used during clinical anesthesia. It is a special anatomical landmark used for blocking anesthesia of the anterior palatal nerve, usually for the extraction of maxillary wisdom teeth or maxillary tooth #7. The anatomical location of the palatal foramen is located about 0.5 cm in front of the posterior margin of the hard palate, and the mucosa covering it is visible as a small depression with the anterior palatal nerve running inside, between the alveolar process of the maxilla and the palatal bone, and it is located at the midpoint of the arch-shaped line from the gingival margin of the palatal side of the maxillary third molar to the palatal midline. When extracting the tooth, local anesthesia is also assisted so that the affected tooth can be extracted, usually without discomfort, and after the extraction of the affected tooth, we should wait for the anesthetic to pass before chewing food to prevent burns.
