“…Thus, the results of the study show that Arnold-Chiari malformation Type I can affect the cochlear and vestibular nuclei, leading to abnormal audio-vestibular results [14,15]. A detailed audio-vestibular evaluation can identify the possible site of the lesion and the pathophysiology of the audio-vestibular symptoms.…”

Background: Arnold-Chiari malformation is defined as a congenital neuroanatomic deformity of the craniocervical junction, which is characterized by herniation of contents from the posterior cranial fossa through the foramen magnum into the cervical spinal canal. There is limited literature on audiological and vestibular evaluation on individuals with Arnold-Chiari malformation. Thus, the present study reports the results of a detailed audio-vestibular evaluation in an adult female diagnosed with Arnold-Chiari malformation.Case report: A detailed audio-vestibular evaluation was carried out in an adult female diagnosed with Arnold-Chiari malformation. Pure tone audiometry, immittance evaluation, otoacoustic emissions, auditory brainstem response (ABR), cervical vestibular evoked myogenic potential (cVEMP), ocular vestibular evoked myogenic potential (oVEMP), and video head impulse test (vHIT) were recorded, and the results were analyzed. The results of the study showed an abnormal prolongation of inter-peak latencies in the ABR, which was seen in both ears. Also, cVEMP and oVEMP was absent in both ears. The results suggest possible compression of the cerebellar tonsils on the cochlear and vestibular nuclei. Conclusions:The study suggests that individuals with Arnold-Chiari malformation should undergo a detailed audio-vestibular evaluation to understand the pathophysiology of the disorder, which can guide further management.

“…Firstly, it is important for the differential diagnosis between CM1 headache and migraine or headaches resulting from other conditions. Inadequate and inaccurate assessment of headache will result in a wrong indication for surgery [ 37 , 38 ]. Several studies have attempted to address this topic and proposed criteria to correctly diagnose the Chiari headache (cough headache, Valsalva headache, occipital or suboccipital, lasting a few minutes) [ 39 , 40 ].…”

Diagnosis and treatment of Chiari malformation type 1 in children: the International Consensus Document

et al. 2021

Background Chiari malformation type 1 (CM1) is a rare condition where agreed classification and treatment are still missing. The goal of this study is to achieve a consensus on the diagnosis and treatment of CM1 in children. Methods A multidisciplinary panel formulated 57 provisional statements based on a review of the literature. Thirty-four international experts (IE) participated in a Delphi study by independently rating each statement on a 4-point Likert scale (“strongly disagree,” “disagree,” “agree,” “strongly agree”). Statements that were endorsed (“agree” or “strongly agree”) by < 75% of raters were re-formulated, or new statements were added, and another Delphi round followed (up to a maximum of three). Results Thirty-five IE were contacted and 34 agreed to participate. A consensus was reached on 30/57 statements (52.6%) after round 1. Three statements were added, and one removed. After round 2, agreement was reached on 56/59 statements (94.9%). Finally, after round 3, which took place during the 2019 Chiari Consensus Conference (Milan, Italy), agreement was reached on 58/59 statements (98.3%) about four main sections (Definition and Classification, Planning, Surgery, Isolated Syringomyelia). Only one statement did not gain a consensus, which is the “definition of radiological failure 24 month post-surgery.” Conclusions The consensus document consists of 58 statements (24 on diagnosis, 34 on treatment), serving clinicians and researchers following children with CM1. There is a clear need for establishing an international network and registry and to promote collaborative studies to increase the evidence base and optimize the long-term care of this patient population.

“…However, in this regard, a group of experts do not consider sufficient evidence of a link between affective disturbances and organic neuropathology. They cite the lack of proper response of behavioral manifestations to surgical treatments as another reason for this lack of association 10 . Also, Garcia et al, reported depression and anxiety as common symptoms among patients with Chiari regardless of surgical status 11 …”
