What are the branches of the infraorbital nerve that supply the eyelid region and nasal region?

• A. Inferior palpebral and External nasal
• B. Inferior palpebral and Superior palpebral
• C. External nasal and Superior labial
• D. Zygomaticofacial and Zygomaticotemporal

Answer: (A)

Branches of the infraorbital nerve spread to the face as it exits the infraorbital foramen, giving off the inferior palpebral nerve to the lower eyelid and the external nasal nerve to the external nose and nasal region. That pairing—inferior palpebral for the eyelid and external nasal for the nose—is why this option is best. Other branches from nearby nerves don’t supply both the eyelid and nasal skin: the superior palpebral would relate to the upper eyelid but isn’t a standard infraorbital branch, the superior labial serves the upper lip, and the zygomaticofacial/zygomaticotemporal branches go to the cheek and temple rather than the eyelid or nose.
