“…Masking was performed according to the method of Hood. 27 Conductive hearing losses (air-bone gap >15 dB HL) were not excluded, as the origin of the hearing loss does not seem to matter in tinnitus induction. 28 The worse-hearing ear was determined by taking the average decibel hearing level over all measured frequencies.…”

Objectives Tinnitus is a common hearing-related disorder, which may have a large impact on daily life. With aging populations worldwide, it is important to gain insight in the occurrence of tinnitus at older ages and to understand its relationship with age-related hearing loss. We investigated the prevalence of tinnitus among a general aging population, across age strata and hearing status. Study Design Cross-sectional. Setting The population-based Rotterdam Study. Methods A total of 6098 participants underwent tinnitus assessment, and 4805 had additional hearing assessment. We determined tinnitus prevalence per 5-year age groups. Hearing impairment was defined as ≥25–dB HL worse ear pure tone average (0.5, 1, 2, 4 kHz). We investigated with multivariable logistic regression the association between hearing impairment and tinnitus. Tinnitus handicap was assessed in 663 participants with daily tinnitus via the Tinnitus Handicap Inventory–screening version (THI-s). Results Tinnitus was prevalent in 21.4% (n = 1304). Prevalent tinnitus was evenly distributed over 5-year age groups. Participants with hearing impairment were more likely to have tinnitus (odds ratio, 2.27; 95% CI, 1.92-2.69) as compared with those without hearing impairment. The median THI-s score was 4 (interquartile range, 0-10), indicating a slight handicap, and 14.6% of the participants reported a moderate or severe handicap (THI-s ≥16). Conclusions In a general elderly population, 1 in 5 persons has tinnitus. Of those with tinnitus, for 1 per 10 persons, the presence of tinnitus interfered with daily life. Participants with hearing impairment were twice as likely to have tinnitus. Despite the age-dependent occurrence of hearing impairment, no such age dependency was found for tinnitus.

“…All thresholds were measured according to the shortened ascending method based on ISO standard 8253‐1, which means that thresholds were defined by the intensity level at which the tone was heard in two out of three ascents . Masking with narrow band noise (1/3 octave) was applied in cases of more than 40 dB difference in air‐conduction thresholds between both ears . Bone‐conduction masking was applied when the bone‐conduction threshold was more than 5 dB better than the air conduction threshold.…”

ABBREVIATIONS ABR Auditory brainstem reflexes ANSD Auditory neuropathy spectrum disorder BVVL Brown-Vialetto-Van Laere syndrome OAE Otoacoustic emissions AIM Mutations in the genes encoding the riboflavin transporters RFVT2 and RFVT3 have been identified in Brown-Vialetto-Van Laere syndrome, a neurodegenerative disorder characterized by hearing loss and pontobulbar palsy. Treatment with riboflavin has been shown to benefit individuals with the phenotype of RFVT2 deficiency. Understanding the characteristics of hearing loss in riboflavin transporter deficiency would enable early diagnosis and therapy. METHOD We performed hearing assessments in seven children (from four families) with RFVT2 deficiency and reviewed results from previous assessments. Assessments were repeated after 12 months and 24 months of riboflavin therapy and after cochlear implantation in one individual. RESULTS Hearing loss in these individuals was due to auditory neuropathy spectrum disorder (ANSD). Hearing loss was identified between 3 years and 8 years of age and progressed rapidly. Hearing aids were not beneficial. Riboflavin therapy resulted in improvement of hearing thresholds during the first year of treatment in those with recent-onset hearing loss. Cochlear implantation resulted in a significant improvement in speech perception in one individual. INTERPRETATION Riboflavin transporter deficiency should be considered in all children presenting with an auditory neuropathy. Speech perception in children with ANSD due to RFVT2 deficiency may be significantly improved by cochlear implantation. Brown-Vialetto-Van Laere syndrome (BVVL) is a progressive neurodegenerative disorder characterized by hearing loss and pontobulbar palsy. 1 Recently, mutations in SLC52A2 and SLC52A3, encoding the riboflavin transporters RFVT2 and RFVT3 respectively, have been identified in a number of individuals with BVVL. 2,3 The phenotype of individuals with RFVT2 deficiency includes hearing loss and sensory ataxia with an onset in early childhood , followed by progressive upper limb weakness, optic atrophy, bulbar weakness, and respiratory failure. 4 While the clinical phenotype of children with BVVL due to RFVT2 deficiency has been reported in detail, the characteristics of the hearing loss have not been explored, despite it often being a presenting or early feature in affected individuals. Reports of individuals with RFVT2 deficiency and of genetically undifferentiated cohorts of individuals with BVVL classify the hearing impairment as a 'sen-sorineural hearing loss' without a clear description of its characteristics. 1,4 Functional studies have demonstrated that SLC52A2 mutations reduce riboflavin transporter expression and riboflavin uptake. 4,5 Riboflavin is critical for the biosynthe-sis of flavin mononucleotide and flavin adenine dinu-cleotide, important cofactors for carbohydrate, amino-acid, and lipid metabolism. Flavin adenine dinucleotide acts as an electron acceptor in acyl-CoA dehydrogenation reactions in mitochondrial fatty acid b-oxidation and bra...
