Nervus intermedius neuralgia (NIN) is an uncommon disorder that affects a sensory branch of the facial nerve. This condition usually provokes a very intense and stabbing pain localized in the depth of the ear canal. Due to the close anatomical proximity, temporomandibular joint (TMJ) pathologies should be included in the differential diagnosis. The treatment of NIN has not been established, although it seems reasonable that the therapeutic approaches used in other more common craniofacial neuralgias, such as trigeminal neuralgia, should be effective. In this paper, the authors present a case report of a female patient diagnosed with NIN who was successfully managed with pharmacological treatment.

Nervus intermedius neuralgia is one of the craniofacial neuralgias, which is extremely rare compared with trigeminal or glossopharyngeal neuralgia. Despite its unique symptom, the aetiology remains unclear. We present a case of a surgically treated 36-year-old woman who suffered from paroxysmal stabbing deep-ear pain for over 10 years. Preoperative magnetic resonance imaging demonstrated a vascular loop compressing the root entry zone of the vestibulocochlear nerve between the seventh and eighth cranial nerves, suggesting nervus intermedius neuralgia as a cause of her pain. Surgical exploration revealed that the nervus intermedius was displaced upward by the anterior inferior cerebellar artery. Transposition of the artery from the brainstem relieved the patient's neurological symptom immediately after the surgery, supporting the hypothesis that nervus intermedius neuralgia could be caused by neurovascular compression.

Nervus intermedius neuralgia is an extremely rare craniofacial neuralgia characterized by intermittent episodes of pain located deep in the ear that last for seconds or minutes and are often triggered by sensory or mechanical stimuli at the posterior wall of the auditory canal without any underlying pathology. Pain can be associated with disorders of lacrimation, salivation, and taste. Despite the fact that the majority of cases is idiopathic, reports can be found in the literature, where this neuralgia is secondary to a neurovascular conflict between the seventh cranial nerve and anterior-inferior cerebellar artery, posterior-inferior cerebellar artery, and vertebral artery or their branches. For these cases a microvascular decompression procedure can be considered a valid therapeutic approach. In a video, we describe microsurgical decompression of the nervus intermedius in a 40-year-old lady who described a 19-year history of short-lasting paroxystic pain felt in the deep external acoustic meatus on the left side, refractory to medical treatment, with no disturbances of lacrimation, salivation, or taste.
