The ophthalmic branch of the trigeminal nerve is indeed the primary nerve responsible for sensation in the upper third of the face. This branch provides sensory innervation to crucial areas such as the forehead, upper eyelids, and the bridge of the nose. It plays a significant role in gathering sensory information from these regions, which is critical for various esthetic procedures, including skin treatments and assessments.

In contrast, while the zygomatic nerve does contribute to facial sensation, it primarily interacts with the areas around the cheek, not the upper third of the face. The facial nerve is predominantly involved in motor functions, controlling muscles of facial expression rather than sensation. The cervical nerve pertains more to the neck area and does not influence the sensory pathways of the facial regions effectively. Thus, the ophthalmic branch best encapsulates the innervation required for the top third of the face.
