Definition

The internal nasal branches of infraorbital nerve are one of the terminal branches of infraorbital nerve as it exits the infraorbital foramen. The internal nasal branches extend medially by passing superficial to the depressor septi muscle along the ala and end up providing sensory innervation to the philtrum, nasal septum and vestibule of nose.

Other terminal branches of infraorbital nerve include inferior palpebral, external nasal and superior labial nerves.
