To anesthetize the red area near the cheek, which nerve should be targeted?

• A. Infraorbital
• B. Supraorbital
• C. Supratrochlear
• D. Mental

Answer: (A)

Understanding the sensory map of the face is essential. The cheek near the orbit is mainly supplied by the infraorbital nerve, a branch of the maxillary division of the trigeminal nerve. It travels through the infraorbital foramen and provides sensation to the lower eyelid, cheek area, side of the nose, and upper lip. Blocking this nerve in the infraorbital region will anesthetize the red area near the cheek. The supraorbital and supratrochlear nerves come from the frontal nerve and supply the forehead and anterior scalp, while the mental nerve comes from the inferior alveolar nerve and supplies the chin and lower lip. So, to numb the cheek region, the infraorbital nerve is the correct target.
