Which of the following statements regarding a regional block of

bupivacaine or 1-2% lidocaine.
- Palpate the supraorbital notch in the orbital rim above
the pupil.
- Inject 1-2 cc directly over the foramen to block the
supraorbital nerve.
- Inject directly into the supraorbital
foramen for faster anesthesia.
Answer:
D
Remediation:
Injection directly into the foramen can injure the nerve.
About the Image(s):
Image 1:
Supraorbital Nerve - Anatomy and Area of Anesthesia
The supraorbital and supratrochlear nerves are branches of the
ophthalmic division of the trigeminal nerve and provide
sensation to the forehead and anterior scalp. Supraorbital nerve
block provides anesthesia of the lateral forehead. Combined with
a block of the adjacent supratrochlear nerve and superior
branches of the infratrochlear nerve, the entire brow and
forehead can easily be anesthetized.
Image 2: Supraorbital Nerve Block - Anesthesia Technique
With the patient in the supine position, sterilely prep the skin
at the injection site. Palpate the supraorbital notch, where the
nerve emerges from the superior orbital rim, directly superior
to the pupil. Using a long skinny needle, first inject 1-3 ml
directly over the supraorbital notch, and then raise a wheal
along a track to the midline, as illustrated, to block the
medial branches and supratrochlear nerve.
