Educational Pearls:
- Local anesthetics injected directly into wounds can cause distortion - especially important in facial lacerations
- Several blocks can be helpful to help numb branches of the trigeminal nerve (CN V) which innervates the face:
-
- Supraorbital nerve block: blocks distribution of V1 (most of the forehead) through injection above the eyebrow
- External nasal nerve block: blocks superficial innervation of nose through injection along the nasal dorsum
- Infraorbital nerve block: blocks innervation to lip and cheek by injection below the eye
- Mental nerve block: blocks innervation to chin and lower lip by injection at the mandible
- Zygomatic nerve block: blocks innervation to temporal scalp and lateral aspect of forehead by injection at the temple
- Greater auricular nerve block: blocks innervation to on and around the lower ear by injection across the sternocleidomastoid
