Orthostatic tinnitus: an otological presentation of spontaneous intracranial hypotension

Audiovestibular impairments associated with intracranial hypotension

“…Our patients mostly had unilateral low-frequency SNHL while one showed bilateral low-and high-frequencies SNHL. These are consistent with the findings of earlier case reports on intracranial hypotension, which described unilateral or bilateral low-frequency SNHL with occasional progression to downsloping mild-to-profound SNHL [6][7][8][9][10][11][12][13][14][15][16][17]. In contrast, the caloric tests were normal in all.…”

“…A study of 30 consecutive patients with intracranial hypotension has described neurotological symptoms including dizziness (30%), tinnitus (20%), aural fullness (20%), and hearing loss (3%) [1], while another reported auditory symptoms in approximately 70% of the patients [6]. Earlier reports have also documented unilateral or bilateral low-frequency sensorineural hearing loss on audiometry with or without vertigo, likewise in Meniere's disease (MD) [6][7][8][9][10][11][12][13][14][15][16][17]. However, previous studies have mostly focused on auditory dysfunction, and no study has attempted objective documentation of vestibular dysfunction in intracranial hypotension.…”

Jugular Compression and Radionuclide Cisternographic Patterns in Patients With Chronic Headache

“…The reason why many of the present JCT‐positive patients reported hearing problems during the compression test is unclear, but may be due to traction of the cochlear nerve. Hearing impairment is a common presenting symptom in patients with IH, suggesting that the cochlear nerve may be the most vulnerable of the cranial nerves to mechanical traction 19–21 . Change in intralabyrinthine pressure due to alteration of the pressure gradient across the cochlear aqueduct may also cause hearing impairment.…”

Quantitative Analysis of White Matter on DTI Images of Patients with Tinnitus: Preliminary Report

“…This includes information regarding the degree of anisotropy as well as the direction of the diffusion of water molecules. Since white matter regions of the brain are an ordered structure due to the myelination and directionality of axons and have a high degree of anisotropy, the ability to detect changes in anisotropy can be extremely useful in the study of diseases such as tinnitus and multiple sclerosis, which are assumed to involve the demyelination of axons [5]- [7]. In particular, it is known that DTI is very effective to diagnose retrograde cerebral disorder such as dementia which is very difficult to be classified [8].…”
