Clinical Examination of the Ear and Hearing

These are of minimal value when accurate pure-tone audiometry, with both air and bone conduction, is available. The most commonly used forks are the 256 and 512 Hz with the former giving more reliable results. They are best activated by striking them gently on the elbow giving a sound of ∼70 dBA when presented to the ear.

16-year-old adolescent patient. The pre-operative result of pure tone audiometry presented a good hearing in the range of frequencies 125–1500 Hzand deafness at other (Fig. 13.12). In order to restore hearing cochlear implanted was performed at high frequencies, while preserving low and mid frequency acoustic hearing in the implanted ear. It is described as ENS of the inner ear.

Pure tone audiometry is the most useful diagnostic test. An MRI scan of the head and internal auditory meati (IAM) is standard practice to rule out a lesion of the IAM/CPA or a white matter lesion e.g. MS. Increasingly, MRI with IV gadolinium is being used to look for objective evidence of hydrops. Vestibular assessment including calorics may also be useful to establish the degree of existing peripheral vestibulopathy and help guide further management. Electrocochleography (ECochG) can be performed but is primarily a research tool. A delayed cVEMP response may also be found.

Audiometric examination was conducted to obtain an audiometric measure of hearing loss. Pure-tone audiometry was administered by audiologists in sound treated facilities. The air conduction thresholds were obtained at 0.25–8.0 kHz using a Madsen OB822 audiometer (Madsen Electronics Copenhagen, Denmark) calibrated to Australian standards. Stimuli were presented through supra-aural headphones using standard TDH-39 earphones. Audiometric thresholds for air-conduction stimuli in both ears were established for frequencies at 0.25, 0.5, 1.0, 2.0, and 4.0 kHz. Both better and worse ear hearing were used in this study. For audiometric threshold comparisons we used the conventional hearing status in accordance with the WHO, using averaged pure-tone audiometric hearing thresholds at 0.5, 1, 2 and 4 kHz. A four-frequency average hearing loss (4FAHL) greater than 25 dB HL in the better hearing ear was used to define hearing loss. This defines hearing loss as bilateral.

The use of the SSQ has been widely reported in the literature [1,9,24–27,34,46]. The SSQ is a self-reported measure of “hearing disability” providing information about the auditory difficulties experienced by the individual in daily life. The functional assessment of hearing difficulties experienced by a person in particular auditory contexts represents a more ecological approach to describing auditory functionality as perception of disability based on interactions between the person and their usual auditory environment [9]. Pure-tone audiometry has the limitation of not being a good indicator of hearing ability [47]. The traditional clinical setting for assessment typically fails to show a patient’s hearing performance in real-life situations and hence questionnaires are a useful tool for capturing everyday life experiences.

In addition to cases with SNHL, loudness assessment has been used for the diagnosis of functional hearing loss (FHL), which is also referred to as non-organic hearing loss or pseudohypacusis. In FHL, despite the elevation of hearing thresholds as determined by the pure tone audiogram, findings from the objective assessment of auditory functions such as otoacoustic emissions (OAEs) and auditory brain stem responses (ABRs) are basically normal. The threshold elevation observed in pure tone audiometry cannot be explained on the basis of an organic pathology (Saravanappa, Mepham, and Bowdler 2005; Drouillard et al. 2014). Psychophysically, FHL is characterised by several characteristics, specifically: a type V pattern in Békésy audiometry, in which the threshold determined using a continuous tone is lower than that determined using a pulsed signal; a discrepancy between the audiometric threshold and the speech detection level; and little or no complaint of actual hearing disturbance (Rintelmann and Harford 1967; Pracy et al. 1996). Especially, a type V pattern in Békésy audiometry is often observed for patients with FHL, but seldom for patients with SNHL or subjects with normal hearing. The type V pattern is thought to be caused by the detection threshold for patients with FHL being judged based on a certain loudness, greater than that at the “true” threshold (Rintelmann and Carhart 1964; Rintelmann and Harford 1967). However, the actual loudness functions for patients with FHL remain unclear.
