Threshold Duration

Where the threshold-duration function has been shown to be systematically affected by sensorineural hearing losses of cochlear origin, preliminary studies have strongly suggested the contrasting finding that conductive hearing losses have no effect. Two series of experiments were performed to examine more fully these separate effects. Threshold-duration functions were obtained from listeners presenting 1) pure conductive and 2) mixed hearing impairments. The results indicate that the threshold-duration function is indeed differentially affected. More exactly, only the sensorineural component of a hearing loss affects the results which are obtained; while the conductive component has no effect. Such findings are interpreted to indicate that the threshold-duration function provides additional information not presently available for the differential diagnosis of auditory disorders.

Threshold Duration

Previous findings on the threshold for tones as a function of their duration have suggested that such functions may be systematically affected by sensori-neural hearing losses of cochlear origin. The present series of investigations was designed to explore this relation further and to determine also whether the amount of hearing loss present has any effect upon the results which are obtained. Preliminary studies were also carried out on a conductively impaired listener to indicate whether hearing losses of this type affect the threshold-duration function. The results indicate that the threshold-duration function is systematically affected by sensori-neural hearing losses of cochlear origin. This effect is manifested by a progressive shortening of the time constant relating threshold to duration and is not uniquely related to the amount of hearing loss present. The results obtained from the conductively impaired listener suggested that this type of hearing loss has no effect on the threshold-duration function, thereby implying that such functions may contribute significantly to the differential diagnosis of auditory disorders.

Infants And Young Children

Wave I latencies were used to predict the magnitude of conductive components in 80 infants and young children (122 ears) with normal hearing, conductive hearing loss due to otitis media or aural atresia, sensorineural hearing loss, and mixed hearing loss. Two prediction methods were used. The first method based predictions on a 0.03-ms wave I latency delay for each decibel of conductive hearing loss. The second method was based on a regression analysis of wave I latency delays and the magnitude of conductive component for the subjects in this study with normal cochlear status. On average, these prediction methods resulted in prediction errors of 15 dB or greater in over one-third of the ears with hearing loss. Therefore, the clinical use of wave I latencies to predict the presence or magnitude of conductive impairment is not recommended for infants and young children. Instead, bone-conduction ABR testing is recommended as a direct measure of cochlear status when behavioral evaluation is not possible.

Brain stem auditory evoked responses (BAER) elicited by bone-conducted click stimuli were studied in 37 subjects. This technique was plagued with problems such as: low amplitude, poor wave configuration, and calibration difficulties. The authors found the technique of limited value in differentiating conductive from neurosensory hearing disorders in all but severely affected subjects. It can, however, evaluate cochlear function in the presence of a known severe conductive hearing loss, ie, external ear atresia. If an abnormal bone-conducted BAER is obtained the etiology of this abnormality (cochlear vs. retrocochlear) cannot be ascertained because a wave I is rarely elicited in individuals with neurosensory hearing disorders. In subjects with a severe conductive hearing loss, air-conduction elicited markedly prolonged wave V latencies. Such a marked prolongation was not observed in individuals with peripheral neurosensory loss and when present signified that a subject had a major conductive component to his hearing disorder. The authors also believe that all control subjects should be established as normal with an audiogram and not by an otologic history or auditory (subjective) click thresholds.

This presentation reports a novel case of chronic lymphocytic leukaemia (CLL), presenting with an early cutaneous lesion within the external auditory canal, in a patient being assessed for conductive hearing loss. It has previously been reported that infiltrative CLL can involve the head and neck; however, isolated external ear canal involvement is rare. Given that the incidence of CLL in Australia is rising, this case highlights the importance of considering CLL as a differential diagnosis for presentations of unilateral conductive hearing loss.
