Anatomy
The supratrochlear nerve is a terminal cutaneous branch of the frontal nerve. The frontal nerve arises from the ophthalmic division of the trigeminal nerve (V1). The supratrochlear nerve exits out from the orbital cavity and runs anterior and then ascends the forehead. It innervates the upper eyelid, forehead, and anterior scalp. The injection site is where it is found superficially at the superomedial aspect of the supraorbital ridge.

Technique
Landmark Guided
- Position the patient supine with their head in a neutral position.
- Use a 1.0 or 2.5 mL syringe with a 30-gauge needle.
- Locate the nasal bridge and the medial aspect of the supraorbital ridge.
- Insert the needle at the medial aspect of the corrugator muscle, just lateral to the procerus and above the eyebrow line to a depth of 4โ5 mm.
- Aspirate to ensure not located in an artery and then inject, producing a small wheal under the skin
