BACKGROUNDThere are no data on cochlear duct lengths (CDL) among Middle East populations.OBJECTIVESThe main aims of this study were to estimate the average CDL in the Saudi population and to compare it with the reported CDL in other regions/ethnic groups outside the Middle East.DESIGNRetrospective study.SETTINGTertiary otolaryngology head and neck surgery center.SUBJECTS AND METHODSTemporal bone CT scans were reviewed to determine CDL. We excluded any CT scan of an ear with a congenital inner ear anomaly or acquired pathology.MAIN OUTCOME MEASURESCDL.SAMPLE SIZE441 temporal bone CT scans.RESULTSThe overall CDL mean was 31.9 mm (range 20.3–37.7 mm). The cochleae of males was significantly longer than of females and cochleae from the left side were significantly longer than of the right side. No significant difference was found between children and adults. Inter-study comparison revealed a significant difference in CDL between the Saudi population in our study and European and Australian studies, but not between the present study and North American studies.CONCLUSIONSThe CDL differed significantly according to side of the cochlea and sex, but not by age. Geographically and ethnically, the mean CDL for Saudis was significantly different from the CDL of subjects of some ethnic backgrounds, but not others. Due to this diversity, we recommend that the CDL be measured before cochlear implant surgery.LIMITATIONSAll the measurements were done by one person, and the subjects’ physical measurements, such as height or head circumference, were not included.

“…Many studies have found that CDL is not age dependent. 1 , 7 , 11 , 22 Our findings support this as there was no significant difference in CDL between the age groups. We think that these corresponding findings confirm that the age factor has no role in the field of studying the causes of the CDL divergence.…”

“…Data in the literature suggest that OAEs and, in particular, DPOAEs may monitor the initial phase of MD and may be able to identify the precise cochlear site involved in an MD crisis [ 27 , 28 ]. In 1985, Eggermont and Schmidt [ 29 ] suggested that in the first stage of MD, a variation of the outer hair cell (OHC) function, caused by hydrops, may determine the typical hearing threshold fluctuation of the disease and may be indirectly registered as a decreased DPOAE amplitude at the low DPOAEs frequencies. They also suggested that in advanced MD, the significant injury or the loss of OHCs, due to both chronic mechanical pressure during the hydropic phase and the potassium intoxication of the inner ear cells after the disruption of Reissner’s membrane [ 30 , 31 ], may explain the absence of DPOAE responses.…”

A number of electrophysiological tests have been proposed for the initial diagnostic assessment or for the follow-up phase of patients affected by Ménière disease. The most common are: (i) vestibular evoked myogenic potentials (VEMPs); (ii) electrocochleography (ECochG); and (iii) otoacoustic emissions (OAEs). This paper presents the latest clinical developments with these 3 testing modalities.The PubMed, Embase, and Cinahl databases were searched from 2006 to December 2016. Full-text articles were obtained in cases where the title, abstract, or key words suggested that the study may be eligible for this review. The medical subject heading (MeSH) terms included the following: Ménière, hearing threshold, vestibule, otoacoustic emissions, inner ear, ECochG, VEMPs. There were 368 identified papers, out of which 87 were eligible for inclusion.Overall the data in the literature are still limited and the recommended procedures have not reached an international consensus. From the available data, one can conclude that none of the electrophysiological tests could be considered as pathognomonic, for the diagnosis of Ménière disease: presently, the tests could be mostly used in a supportive role to the clinical diagnosis. Hopefully, in the future, improved technology in electrophysiological testing could contribute to the development of better strategies for the diagnosis of Ménière disease.

“…An early report on MD by Eggermont and Schmidt [30] stated that in the early phase of MD, a minimal variation on the outer hairy cells function, caused by hydrops, can determine the typical auditory threshold luctuation; this phenomenon can be indirectly observed as a reduction in the DPOAE amplitude particularly in the low DPOAE frequencies. In cases of advanced MD, the severe damage or the loss of inner ear, outer hair cells, is responsible for DPOAEs absence.…”

“…Although Roter et al [35] found that DPOAEs are not as accurate as the transtympanic electrocochleography, other authors [27,29,30] support the role of DPOAEs as a reliable method allowing the detection of endolymphatic hydrops and the cochlear damage in MD [19,33].…”

Otoacoustic emissions (OAEs) are responses originating from the inner ear. Clinically they are evoked by diferent families of acoustic stimuli, such as transient acoustic clicks, tone pips, and pure tones. Upon stimulation, the acoustic energy is transformed in the middle ear at acoustic pressure acting upon the stapes footplate. The pressure wave inside the cochlea stimulates the OAE generators and a reverse acoustic energy (the OAE response) propagates from the inner ear, through the stapes and the middle ear structures, to the tympanic membrane. Considering that the acoustic energy has to cross the middle ear structures twice, the functional status of the middle ear can inluence or atenuate considerably the OAE response. In this context, any vestibular alteration can inluence the middle ear mechanics (mainly the middle ear impedance) and consequently the OAE response characteristics. The data in the literature indicate that OAEs are very sensitive to changes in the intracranial pressure. These pressure alterations during the Meniere's hydrops phase are expressed as changes in the intralabyrinthine pressure. Other studies have presented data supporting the assumption that OAEs can adequately monitor middle ear changes induced by the presentation of the glycerol test. The data in the literature suggest that OAEs can monitor the progress of Meniere's disease using reliable indices.
