To perform the cranial infraorbital block in the dog, palpate the infraorbital foramen as a depression in the alveolar mucosa apical (dorsal) to the distal root of the maxillary third premolar or the mesial root of the maxillary fourth premolar. In the cat, the infraorbital foramen is located at the mesial aspect of the third premolar.

Four nerve blocks are commonly used for dental nerve blocks in dogs and cast to the different regions of the oral cavity of mesocephalic and dolicocephalic dogs—the infraorbital and …

The infraorbital nerve exits the infraorbital foramen along with the infraorbital artery and vein. The foramen is located approximately dorsal to the 3rd premolar (dogs) or 2nd premolar (cats).

Local anaesthetic drugs used in local and regional blockade can completely block the transmission of nociceptive impulses, decreasing both intra-operative nociception and postoperative pain, while decreasing the potential incidence of adverse effects that can be associated with systemic boluses of drugs.

After giving off the caudal maxillary alveolar nerve, the maxillary nerve enters the infraorbital canal, where it is called the infraorbital nerve. While the infraorbital nerve is traversing the infraorbital canal, it gives off two more branches that exit ventrally from the canal.

Lab Objectives: • Dissect superficial nerves of the head: - facial nerve and its branches (innervate facial expression muscles) - mandibular nerve branches: lingual nerve & inferior alveolar nerve also, as you dissect vessels, find: - maxillary nerve, which becomes infraorbital n. (p. 259) - vagus nerve and its laryngeal branches (p. 260)

2009年6月1日 · Infraorbital, maxillary, mental, and mandibular (inferior alveolar) nerve blocks provide anesthesia to the upper or lower jaw and are commonly performed in practice for dental extractions. These blocks are also used for any surgical procedure of the …

2024年7月7日 · The trigeminal nerve (cranial nerve V) is the main nerve that innervates the teeth. Dental nerve blocks in veterinary practice are used to desensitise five major nerves; the maxillary, infraorbital, major palatine, inferior alveolar (mandibular) and middle mental nerves [105].

Nerve blocks are essential before oral surgical procedures are performed in dogs. Not only do nerve blocks provide a basis for pain management in the immediate postoperative period, they also allow for decreased minimum alveolar concentration of inhalant anesthetic, resulting in a safer procedure.

Approach: Dog: cranial border P4, Cat: below medial canthus Needle position: Enter foramen in caudal direction, place the needle opening in the entrance to the infraorbital canal and compress the soft tissue over the foramen with the thumb of the non-dominant hand during injection. CAVE: The infraorbital canal in cats is very short (approx. 4mm)
