microvascular decompression of the anterior inferior cerebellar artery for intermediate nerve neuralgia
Stereotactic and Functional Neurosurgery, 2010Co-Authors: Walid M Younes, Hansholger Capelle, Joachim K KraussAbstract:The authors present the case of a 63-year-old woman with a 5-year history of intractable paroxysmal 'atypical' otofacial pain. The patient's pain attacks were not typical for either trigeminal or vagoglossopharyngeal neuralgia. Surgical exploration via a suboccipital retromastoid craniotomy showed vascular compression of the Nervus intermedius by the anterior inferior cerebellar artery and the patient's pain was successfully managed with microvascular decompression.

anterior inferior cerebellar arteries juxtaposed with the internal acoustic meatus and their relationship to the cranial nerve vii viii complex
Cureus, 2017Co-Authors: Fernando Alonso, Marios Loukas, Mohammad W Kassem, Joe Iwanaga, Rod J Oskouian, Amin Demerdash, Shane R TubbsAbstract:Vascular loops in the cerebellopontine angle (CPA) and their relationship to cranial nerves have been used to explain neurological symptoms. The anterior inferior cerebellar artery (AICA) has variable branches producing vascular loops that can compress the facial cranial nerve (CN) VII and vestibulocochlear (CN VIII) nerves. AICA compression of the facial-vestibulocochlear nerve complex can lead to various clinical presentations, including hemifacial spasm (HFS), tinnitus, and hemiataxia. The formation of arterial loops inside or outside of the internal auditory meatus (IAM) can cause abutment or compression of CN VII and CN VIII. Twenty-five (50 sides) fresh adult cadavers underwent dissection of the cerebellopontine angle in the supine position. In regard to relationships between the AICA and the nerves of the facial/vestibulocochlear complex, 33 arteries (66%) traveled in a plane between the facial/Nervus intermedius nerves and the cochlear and vestibular nerves. Five arteries (10%) traveled below the CN VII/VIII complex, six (12%) traveled posterior to the nerve complex, four (8%) formed a semi-circle around the upper half of the nerve complex, and two (4%) traveled between and partially separated the Nervus intermedius and facial nerve proper. Our study found that the majority of AICA will travel in a plane between the facial/Nervus intermedius nerves and the cochlear and vestibular nerves. Although the relationship between the AICA and porus acusticus and AICA and the nerves of the CN VII/VIII complex are variable, based on our findings, some themes exist. Surgeons should consider these with approaches to the cerebellopontine angle.

isolated deep ear canal pain possible role of auricular branch of vagus nerve case illustrations with cadaveric correlation
World Neurosurgery, 2016Co-Authors: Kentaro Watanabe, Shane R Tubbs, Shunsuke Satoh, Ali R Zomorodi, Wolfgang Liedtke, Moujahed Labidi, Allan H Friedman, Takanori FukushimaAbstract:Glossopharyngeal, Nervus intermedius, and vagus neuralgias can all present with ear pain. However, to our knowledge, there have been no reports of otalgia as the only symptom of vagus neuralgia. The seventh, ninth, and tenth cranial nerves have many interneural connections, and the exact anatomy and pathophysiology of these neuralgias are often not clear. Moreover, symptoms due to involvement of any of these nerves can be difficult to attribute solely to 1 of them. The overlapping sensory innervation of the external auditory canal can lead to misdiagnosis in patients suffering from otalgia. This report presents a case of pure otalgia due to vascular compression of the vagus nerve (VN) and considers the microanatomic differences between glossopharyngeal and Nervus intermedius neuralgia via cadaveric dissections. We report 2 cases of external auditory canal pain that continued following microvascular treatment of trigeminal neuralgia. Intraoperatively and at secondary operation, the posterior inferior cerebellar artery was found to be adherent and to penetrate between the fibers of the VN. Following microvascular treatment of the VN, the pain resolved. Conclusion This is the first report of vagus neuralgia presenting solely with ear pain. Surgeons should be aware that primary external auditory canal pain can be due to vagus neuralgia via its auricular branch and that such patients can be misdiagnosed with glossopharyngeal or Nervus intermedius neuralgias.

neural connections between the Nervus intermedius and the facial and vestibulocochlear nerves in the cerebellopontine angle an anatomic study
Author, 2015Co-Authors: Shane R Tubbs, Nicole Hose, Marios Loukas, Raffaele De Caro, Aaron A CohengadolAbstract:Unexpected clinical outcomes following transection of single nerves of the internal acoustic meatus have been reported. Therefore, this study aimed to investigate interneural connections between the Nervus intermedius and the adjacent nerves in the cerebellopontine angle. On 100 cadaveric sides, dissections were made of the facial/vestibulocochlear complex in the cerebellopontine angle with special attention to the Nervus intermedius and potential connections between this nerve and the adjacent facial or vestibulocochlear nerves. A Nervus intermedius was identified on all but ten sides. Histologically confirmed neural connections were found between the Nervus intermedius and either the facial or vestibulocochlear nerves on 34 % of sides. The mean diameter of these small interconnecting nerves was 0.1 mm. The fiber orientation of these nerves was usually oblique (anteromedial or posterolateral) in nature, but 13 connections traveled anteroposteriorly. Connecting fibers were single on 81 % of sides, doubled on 16 %, and tripled on 3 %, six sides had connections both with the facial nerve anteriorly and the vestibular nerves posteriorly. On 6.5 % of sides, a connection was between the Nervus intermedius and cochlear nerve. For vestibular nerve connections with the Nervus intermedius, 76 % were with the superior vestibular nerve and 24 % with the inferior vestibular nerve. Knowledge of the possible neural interconnections found between the Nervus intermedius and surrounding nerves may prove useful to surgeons who operate in these regions so that inadvertent traction or transection is avoided. Additionally, unanticipated clinical presentations and exams following surgery may be due to such neural interconnections.

DOI 10.1007/s10194-011-0350-4 BRIEF REPORT Familial neuralgia of occipital and intermedius nerves in a Chinese family
2013Co-Authors: Yu Wang, Franz Riederer, Lin Huang, Dominik A. EttlinAbstract:Ó The Author(s) 2011. This article is published with open access at Springerlink.com Abstract Cranial nerve neuralgia usually occurs sporadically. Nonetheless, familial cases of trigeminal neuralgia are not uncommon with a reported incidence of 1–2%, suggestive of an autosomal dominant inheritance. In contrast, familial occipital neuralgia is rarely reported with only one report in the literature. We present a Chinese family with five cases of occipital and Nervus intermedius neuralgia alone or in combination in three generations. All persons afflicted with occipital neuralgia have suffered from paroxysmal ‘electric wave’-like pain for years. In the first generation, the father (index patient) was affected, in the second generation all his three daughters (with two sons spared) and in the third generation a daughter’s male offspring is affected. This familial pattern suggests an X-linked dominant or an autosomal dominant inheritance mode

Familial occipital and Nervus intermedius neuralgia in a Swiss family
The Journal of Headache and Pain, 2010Co-Authors: Franz Riederer, Peter S. Sándor, Michael Linnebank, Dominik A. EttlinAbstract:Familial trigeminal neuralgia has been reported in 1–2% of cases consistent with an autosomal dominant inheritance. We present a Swiss family with several members suffering from occipital and Nervus intermedius neuralgia alone or in combination. We suggest that peripheral sensory anastomoses or central convergence of afferent pathways could explain neuralgia affecting two cranial nerves. The pedigree has two main characteristics: (1) affected individuals in two generations and (2) in the first generation the father is affected, in the second generation all women are affected, and none of the men. This is suggestive of an X-linked dominant or an autosomal dominant mode of inheritance.
