Although pre-operative symptoms related to dysfunction of this nerve are uncommon, postoperative symptoms are frequent. The nervus intermedius carries secretomotor fibers to the submandibular, sublingual and minor salivary glands, the nasal and palatine mucus glands and the lacrimal gland. It also carries taste from the anterior two-thirds of the tongue and hard palate, and some somatic afferent fibers from the external auditory meatus. Damage to the nervus intermedius is common in CPA surgery. Reinnervation or transephaptic transmission probably accounts for the onset of lacrima-tion during eating ("crocodile tears") which is present in 44% of patients post-operatively. A reduction in tear production is present in 72% of patients, whilst 48% admit to changes in taste sensation post-operatively . To reduce the distress caused by these symptoms all patients should be adequately counselled pre-operatively.
