Palatine nerve block
The palatine nerve block partially anesthetizes the maxillary incisors, canines, and premolars. This block is recommended
in cats. Keep in mind that most of the innervation to the maxillary arch comes from the infraorbital nerve, and the palatine
block only offers some degree of anesthesia. Thus in dogs, the palatine nerve block should be performed simultaneously with
the infraorbital nerve block to offer the highest degree of analgesia. Inject 0.1 to 0.2 ml bupivacaine (0.5%) at a midpoint
between the mesial aspect of the maxillary carnassial tooth and the palatal midline (Figure 6).

carnassial tooth and the palatal midline (arrows). One or both sides may be blocked simultaneously.
