Clinical Presentation

Following trigeminal sensory nerve injury, patients present with various types of sensory disturbance including anesthesia, paresthesia, dysesthesia, hyperesthesia, hyperalgesia, hypoalgesia, and allodynia.[19] The taste fibers from the chorda tympani are conveyed to the tongue via the lingual nerve, and disturbance of taste also occurs frequently. The disturbance is compensated partially by the other taste receptors within the oral cavity.[20] Recovery of altered taste is not expected in fourth- and fifth-degree Sunderland injuries.[21]
