Infraorbital Nerve

Version 1

Abstract

In about 54% of cases, a middle alveolar nerve arises from the infraorbital, 28% show significant variation, and in 18% the middle alveolar nerve is absent. The branch supplying the upper lip may run independently in the floor of the orbital cavity; other branches of the nerve arise earlier and enter another canal medial to the main channel. The nerve may be doubled.
