====== Supraorbital nerve ======
{{ ::supraorbitalnerve.jpg?200|}}

The supraorbital and [[supratrochlear nerve]]s arise from the [[frontal nerve]] and are 2 of the 5 branches of [[V1]] (ophthalmic division of the [[trigeminal nerve]]). The supraorbital [[nerve]] is the largest branch. It exits the [[orbit]] through the [[supraorbital notch]] or foramen, usually within the medial third of the orbital roof (mean distance from exit to medial angle of the orbit: 20 mm (range: 5–47)

the supraorbital, supratrochlear and auriculotemporal nerves and their possible clinical significance.

The [[supratrochlear nerve]] exits the orbit without a foramen or notch 3–38 mm medial to the supraorbital nerve (mean: 15.3 mm

the most medial branch varies from 8–30 mm lateral to the patient’s
midline

The supraorbital [[nerve]] passes through the [[supraorbital foramen]], and gives off, in this situation, palpebral filaments to the upper [[eyelid]]. Additionally, it supplies the [[conjunctiva]] of the [[eye]], the [[frontal sinus]], and the skin from the forehead extending back to the middle of the [[scalp]].

The [[supraorbital nerve]] frequently constitutes the lateral [[landmark]] of the [[frontal sinus]], consequently keeping lateral to it, avoids entering the sinus cavity. However, there are several variants that have to be considered.
