This block anesthetizes the forehead and anterior third of the scalp. To perform, locate the supraorbital nerve foramen in the medial aspect of the supraorbital ridge as shown in A. After cleansing, insert a small needle (25 or 27 gauge) to a depth of 0.5 to 1 cm just medial and directed towards the foramen as shown in B. Inject 1 to 3 mL of local anesthetic. In older children, adolescents, and adults who report paresthesias, withdraw the needle until paresthesias resolve prior to injection of anesthetic. Allow 5 to 10 minutes for complete anesthesia to occur.
