Audiological benefit and subjective satisfaction with ADHEAR Hearing System in adult users with transient hearing loss following middle ear surgery

We recorded auditory-evoked magnetic responses with a whole-scalp 122-channel neuromagnetometer from seven adult patients with unilateral conductive hearing loss before and after middle ear surgery. The stimuli were 50-msec 1-kHz tone bursts, delivered to the healthy, nonoperated ear at interstimulus intervals of 1, 2, and 4 seconds. The mean preoperative pure-tone average in the affected ear was 57 dB hearing level; the mean postoperative pure-tone average was 17 dB. The 100-msec auditory-evoked response originating in the auditory cortex peaked, on average, 7 msecs earlier after than before surgery over the hemisphere contralateral to the stimulated ear and 2 msecs earlier over the ipsilateral hemisphere. The contralateral response strengths increased by 5% after surgery; ipsilateral strengths increased by 11%. The variation of the response latency and amplitude in the patients who underwent surgery was similar to that of seven control subjects. The postoperative source locations did not differ noticeably from preoperative ones. These findings suggest that temporary unilateral conductive hearing loss in adult patients modifies the function of the auditory neural pathway. (Otolaryngol Head Neck Surg 1998;119:125-30.)

Otoscopic Examination

Thirty-five cholesteatomas medial to intact eardrums were treated in 34 children between 1976 and 1982. Six (18%) children had never had a documented episode of otitis media. Seventeen (50%) children, in whom the lesion was diagnosed at an early stage, underwent simple excision of the cholesteatoma without the need for extensive middle ear surgery. Findings from postoperative audiograms were normal for all such children. Cholesteatoma has recurred in eight (23%) children to date. Most recurrences were diagnosed 15 months or less after surgery. Routine careful otoscopic examination is essential in order to discover cholesteatoma at an early stage and to avoid hearing loss and the need for extensive otomastoid surgery. In order to perform an accurate examination of the eardrum, a halogen-illuminated otoscope and pneumo-otoscopy should be used by the pediatrician routinely. Particular attention should be paid to the posterior-superior quadrant of the tympanic membrance where a cholesteatoma is usually located.

Conductive Hearing

A rare facial nerve anomaly was incidentally discovered whilst performing a tympanoplasty and ossicular reconstruction on a patient with an acquired unilateral conductive hearing loss. The nerve was seen to bifurcate and straddle a normal stapes superstructure as it ran posteriorly through the middle ear, a unique and as yet unreported combination. This case highlights the importance of vigilance regarding facial nerve anatomical variations encountered during middle-ear surgery thus avoiding inadvertent damage. The purported embryological mechanism responsible for such anomalies of the intra-tympanic facial nerve is discussed.

Conductive Hearing

This study investigated whether conductive hearing loss reduces normal binaural hearing advantages and whether binaural hearing advantages are normal in patients who have had hearing thresholds improved by middle ear surgery. Binaural hearing was assessed at a test frequency of 500 Hz using the masking level difference and interaural time discrimination thresholds. Results indicated that binaural hearing is often poor in conductive lesion patients and that the reduction in binaural hearing is not always consistent with a simple attenuation of the acoustic signal. Poor binaural hearing sometimes occurs even when middle ear surgery has resulted in bilaterally normal hearing thresholds. Our preliminary results are consistent with the interpretation that auditory deprivation due to conductive hearing loss may result in poor binaural auditory processing.
