ABSTRACT: BACKGROUND AND PURPOSE: A detailed knowledge of the normal Magnetic Resonance (MR) anatomy of the vestibular endolymphatic space (ES) could be useful to understand the linkage between endolymphatic hydrops (EH) and Ménière's disease (MD). Our aim was to describe the MR anatomy of the vestibular ES as depicted by MR imaging in healthy ears. METHODS: This report describes a single-center retrospective study. Three readers analyzed the healthy ears of 22 consecutive patients who had undergone MRI for unilateral sudden hearing loss. The readers described the vestibular ES based on a delayed post-contrast 3D-FLAIR sequence according to six well-defined planes, three oblique sagittal (lateral, intermediate and medial) planes and three axial (superior, intermediate and inferior) planes. RESULTS: On sagittal lateral and intermediate planes, we identified the SSC ampulla combined with the utricle in 22/22 ears. On the sagittal medial plane, the saccule was detectable in 15/22 (68%) ears, having a club shape with the long axis oriented cranio-caudally; in 7/22 (32%) ears, the saccule presented an oval/round shape that appeared more conspicuously on the axial intermediate plane. The ES occupied the half superior portion of the vestibule in 22/22 ears, never contacting the round and oval windows. On the axial plane, in 17/22 cases, the ES showed a Y-shaped arrangement, while in 5/22 ears (23%), the ES presented a more globular shape. CONCLUSION: MR imaging represents a valid tool to explore the in vivo anatomy of the vestibular ES and to highlight its variability in normal ears.

ABSTRACT: BACKGROUND: In Tinnitus Retraining Therapy (TRT) sound stimulation is conventionally performed with low-level broadband sound generators; since the patient has to receive it for many hours in a day, it is important that the sound is tolerable and agreeable to the patient. A clinical trial was undertaken to evaluate the effect of different colour sound generators on tinnitus. The colour of a sound refers to the power spectrum of the signal. The sound generators used in this study provide the option to choose the preferred or most acceptable sound among white, red and pink noise. METHODS AND FINDINGS: Changes in Tinnitus Handicap Inventory and Numeric Rating Scales were measured in 20 patients after 3 and 6 months following the fitting of ear-level multi-colour sound generators. The outcomes were compared to a similar group of 20 participants receiving the same management except through conventional white noise sound generators. Significant improvements were obtained in both groups following 3 and 6 months after fitting. No significant difference was found between the two groups using one or the other type of sound. Two thirds of the patient preferred white noise, making it the most appealing amongst the options. The rest of the patients indicated red noise as the preferred sound given that it reminded them of soothing noises like shower or rainfall. No one chose pink noise. CONCLUSIONS: TRT with different colour sound generators is effective in reducing the discomfort caused by tinnitus in normal hearing patients. Enabling the patients to choose their preferred sound after short trial periods achieved higher patient satisfaction. This practice could help tailor individualized treatment for each patient.

Electronic address: stefania.barozzi@unimi.it. · Audiology Unit Department of Clinical Sciences, Community Health Università degli Studi di Milano, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, via Pace 9, Milan, Italy. ·Am J Otolaryngol · Pubmed #24882750.

ABSTRACT: We report the case of a man affected by a unilateral Ménière's disease who, after being free from vertigo spells and tinnitus for more than ten years, manifested an exacerbation of symptoms just before the diagnosis of a choroidal melanoma. Melanoma is an aggressive form of cancer derived from neuroectodermal melanocytes. Melanocytes are present in the inner ear where they contribute to the production of endolymphatic potentials and to the maintenance of normal volumes of the inner ear fluids. A possible autoimmune connection between the exacerbation of audiovestibular symptoms and melanoma is discussed.

4 Article Benign paroxysmal positional vertigo and tinnitus. 2013

Barozzi, Stefania / Socci, Marina / Ginocchio, Daniela / Filipponi, Eliana / Martinazzoli, Maria Grazia Troja / Cesarani, Antonio. ·Department of Clinical Sciences and Community Health, Università degli Studi Milano. stefania.barozzi@unimi.it ·Int Tinnitus J · Pubmed #24995895.

ABSTRACT: INTRODUCTION: In our clinical experience, some of the patients affected by benign paroxysmal positional vertigo (BPPV) reported the onset of tinnitus shortly before or in association with the positional vertigo. OBJECTIVES: The aim of this study was to describe the prevalence and the clinical patterns of tinnitus episodes which occurred in association with BPPV and to suggest possible interpretative hypotheses. METHODS: 171 normal hearing patients affected by BPPV (50 males and 122 females; age range: 25-77 years; mean age 60.3 years ± 14.9) underwent pure tone audiometry, immittance test and a clinical vestibular evaluation before and after repositioning manoeuvers. Those suffering from tinnitus were also assessed using visual analogue scales and tinnitus handicap inventory. RESULTS: 19.3% of the patients reported the appearance of tinnitus concurrently with the onset of the positional vertigo. It was mostly unilateral, localized on the same ear as the BPPV, slight in intensity and intermittent. Tinnitus disappeared or decreased in all patients except two, either spontaneously, before performing the therapeutic manoeuvers, or shortly after. CONCLUSIONS: A possible vestibular origin of tinnitus determined by the detachment of macular debris into the ductus reuniens and cochlear duct is discussed.

ABSTRACT: Williams syndrome is a neurodevelopmental disorder associated with cardiovascular problems, facial abnormalities and several behavioural and neurological disabilities. It is also characterized by some typical audiological features including abnormal sensitivity to sounds, cochlear impairment related to the outer hair cells of the basal turn of the cochlea, and sensorineural or mixed hearing loss, predominantly in the high frequency range. The aim of this report is to describe a follow-up study of auditory function in a cohort of children affected by this syndrome. 24 patients, aged 5-14 years, were tested by means of air/bone conduction pure-tone audiometry, immittance test and transient evoked otoacoustic emissions. They were evaluated again 5 years after the first assessment, and 10 of them underwent a second follow-up examination after a further 5 years. The audiometric results showed hearing loss, defined by a pure tone average >15 dB HL, in 12.5% of the participants. The incidence of hearing loss did not change over the 5-year period and increased to 30% in the patients who underwent the 10-year follow-up. Progressive sensorineural hearing loss was detected in 20% of the patients. A remarkable finding of our study regarded sensorineural hearing impairment in the high frequency range, which increased significantly from 25% to 50% of the participants over the 5-year period. The increase became even more significant in the group of patients who underwent the 10-year follow-up, by which time the majority of them (80%) had developed sensorineural hearing loss. Otoacoustic emissions were found to be absent in a high percentage of patients, thus confirming the cochlear fragility of individuals with Williams syndrome. Our study verified that most of the young Williams syndrome patients had normal hearing sensitivity within the low-middle frequency range, but showed a weakness regarding the high frequencies, the threshold of which worsened significantly over time in most patients.

6 Article Audiological findings in Williams syndrome: a study of 69 patients. 2012

ABSTRACT: The aim of this study was to investigate, in a clinical setting, the auditory function of a group of individuals affected by Williams syndrome (WS). Sixty-nine patients with WS, aged 2-30, underwent comprehensive audiological testing including air/bone conduction behavioral audiometry, speech audiometry, tympanometry and measurement of the acoustic reflex, transient evoked otoacoustic emissions and brainstem auditory evoked responses. Hearing loss, defined by a pure-tone average above 15 dB HL, affected 22.6% of the patients studied with traditional audiometry and was mostly slight in severity. Hearing loss was conductive in 9.4% of patients, mainly children with otitis media with effusion, and sensorineural in 13.2% of patients. However, 30% of the ears studied had a hearing impairment in the high frequency range (high-frequency pure-tone audiometry above 15 dB HL), higher in participants above 15 years (46.15%) than in the younger ones (23.45%). Contralateral stapedial reflexes were present in all patients with A-type tympanograms. Transient otoacoustic emissions were absent in 44% of the ears of patients with normal hearing. Brainstem auditory evoked responses fell within normal ranges thus confirming the absence of retrocochlear dysfunction. Although hearing loss does not seem to be frequent, a cochlear fragility, especially in the high frequency range, related to outer hair cells is characteristic of WS. Therefore we strongly recommend monitoring patients affected by WS using annual audiometric tests and performing otoacoustic emissions in order to identify a subclinical cochlear dysfunction which might benefit from an audiological follow up before the possible onset of hearing loss.
