Purpose: Idiopathic intrakranial hypertension (IIH) is a state of high in the head pressure without any identifiable cause. This is the cause of obesity that increases the frequency of occurrence worldwide. This pathology has a strong connection with tegmental dehisance and spontaneous brain-omurylic fluid (BOS) fluid. Superior semicircular canal depression (SSKD) is also associated with obesity in literature. The objective of this study is to determine the incidence of SSKD in IIH patients, to evaluate the outcomes of odyovestibular in IIH patients with SSKD, and to discuss the possible pathogenetic mechanisms that cause this association. Tools and Methods: 25 consecutive patients diagnosed with IIH in the neurology department between 2016-2018 were evaluated. The study was taken to a group of 10 patients who fulfilled the required criteria and agreed to participate in this study. Odyometry, timpanometry, vestibular stimulated myogenic potential (VEMP) tests and high-resolution computer tomography (HRCT) images were performed. The control group was formed from 20 patients, aged and gender-compatible, who applied to our clinic with various complaints and applied HRCT between 2016-2018 years. Results: SSKD was detected in 1 (10%) patients with IIH in the study group. Two (20%) of patients were examined in the bone canal. No patient in the control group was diagnosed with a radiographic SSKD or bone canal examination. Patients with SSKD were diagnosed with pathological findings in VEMP. The result: While our results are not statistically meaningful, the SSKD incidence appears to be higher in IIH. Advanced work with a wide range of patients is essential.
