Sensorineural Hearing Loss and Tinnitus Characteristics in Patients With Idiopathic Intracranial Hypertension

Abstract

Objectives: To characterize patterns of sensorineural hearing loss (SNHL) and tinnitus in patients with idiopathic intracranial hypertension (IIH). Study Design: Retrospective chart review. Setting: Tertiary referral center. Patients: Adult patients diagnosed with IIH via lumbar puncture (LP) between 2010 and 2020 who had available audiograms. The study included a total of 40 patients; 33 women, and 7 men with a median age of 43. Interventions: Diagnostic LP and audiogram. Main Outcome Measures: Otologic symptoms, ophthalmologic signs, hearing thresholds, cerebrospinal fluid opening pressures.Results: The most commonly reported symptoms were tinnitus in 28 (70%, 23 pulsatile and 5 tonal), aural fullness in 11 (28%), and vertigo in 10 (25%). Twenty-nine patients had ophthalmologic examinations and 18 had evidence of papilledema. Twenty-five (63%) patients had hearing loss in at least one ear at one frequency range. Patients presented with both unilateral and bilateral hearing loss across low, middle, and high frequency ranges. No significant association was observed between hearing loss threshold and LP opening pressure except for 250 Hz in the left ear. After stratification by tinnitus group (pulsatile, tonal, and no tinnitus), no significant difference was found between mean hearing loss threshold at different frequencies. In addition, no significant mean age difference was identified in patients within each tinnitus group. Conclusions: There was no classic pattern or presentation for hearing loss in our IIH patients. They developed sudden, unilateral, or bilateral SNHL in low, middle, or high frequency range. The degree of hearing loss did not correlate with CSF opening pressure.

Systematic Evaluation of the Efficacy of Acupuncture Associated with Physical and Mental Intervention when Treating Idiopathic Tinnitus and the Improvement of Tinnitus Symptoms

“…The onset of idiopathic tinnitus is acute or chronic, with or without hearing and psychological disorders, which is usually associated with hearing loss, noise exposure, aging, and stress. The auditory sensitivity in tinnitus population is 40-86% [ 3 , 4 ]. Most research reports show that the prevalence of adult tinnitus is about 10-19%, and in recent years, the prevalence of adult tinnitus is increasing at an annual rate of 3%, and the incidence rate increases with age.…”

“…Long-term and larger studies are awaited to study the evolving relationship between intracranial pressures and hearing loss. [ 13 ]…”
