We propose middle ear implants (MEI) as alternative hearing restoration option for patients with fibrous dysplasia of the temporal bone (FDTB). A 60-year-old man presented with unilateral right-sided conductive hearing loss (CHL) and FDTB. The Vibrant Soundbridge (VSB) MEI was implanted in the right ear. Preoperatively, the right side had a pure tone average (PTA) threshold of 67 dB, speech reception threshold (SRT) = 75 dB HL, and speech discrimination score (SDS) = 54% at 80 dB HL presentation level. Postoperative aided PTA threshold of the right ear was 28 db, aided SRT = 30 db, and SDS = 96% at 65dB HL. After excluding cholesteatoma, VSB provides an alternative hearing restoration technique for adults with FDTB and CHL due to stenosis of the external auditory canal and/or ossicular crowding.

AbstractObjective:We present a technique which we have found useful for the management of congenital cholesteatoma extensively involving the middle ear.Case report:A five-year-old boy was presented to our department for management of a white mass on the right tympanic membrane. This congenital cholesteatoma extensively occupied the tympanic cavity. It was removed through an extended tympanotomy approach using our modified sleeve technique. The conventional tympanotomy approach was extended by gently separating the tympanic annulus from its sulcus in a circular manner. The firm attachment of the tympanic membrane at the umbo was not severed, in order to avoid lateralisation of the tympanic membrane.Conclusion:Although various operative techniques can be used, our modified sleeve tympanotomy approach provides a similarly sufficient and direct visualisation of the entire middle ear, with, theoretically, no possibility of lateralisation of the tympanic membrane and subsequent conductive hearing loss.

Penetrating middle ear injury can result in hearing loss, vertigo, and facial nerve injury. We describe the cases of 2 children with penetrating trauma to the right ear that resulted in ossicular chain disruption; one injury was caused by cotton-tipped swabs and the other by a wooden matchstick. Symptoms in both children included hearing loss and otalgia; in addition, one child experienced ataxia and the other vertigo. Physical examination in both cases revealed a perforation in the posterosuperior quadrant of the tympanic membrane and visible ossicles. Audiometry identified a moderate conductive hearing loss in one child and a mild sensorineural hearing loss in the other. Both children underwent middle ear exploration and reduction of a subluxed stapes. We discuss the diagnosis, causes, and management of penetrating middle ear trauma. To reduce the morbidity associated with these traumas, otologic surgeons should act promptly and be versatile in choosing methods of repairing ossicular chain injuries.

Two comparative studies were performed in six subjects using partially implantable middle ear implants (MEI). The sound quality was evaluated by speech discrimination tests and sound evaluation tests. In the first experiment, the performance of the output transducer of the MEI and an ear phone of a conventional hearing aid was compared. The MEI showed better results than the hearing aid in both the speech discrimination tests and sound quality rating. In the second experiment, four kinds of frequency responses for the external component of the MEI were compared. Sound quality evaluation in a wide frequency response with a peak at 4000 Hz were superior to those with the frequency response of the present MEI model. In conclusion, improvement of the external component in the frequency response can provide better performance of the MEI.

Conductive Hearing

Up to 3 million people in Britain might be helped by hearing aids.1 2 Most are over 65 years of age, but some are infants. All should be referred to specialist centres for assessment as soon as possible. Hearing aids generally help most in disorders of the middle ear (conductive hearing loss); they can also help those with sensorineural and other forms of hearing loss. The use of an aid often needs to be supplemented by lip reading and other means of auditory training.1 3

<p class="abstract"><strong>Background:</strong> Chronic squamosal otitis media can occur due to many conditions affecting the middle ear. Most common sign of developing a chronic squamosal otitis media is formation of a retraction pocket in the tympanic membrane leading to further development of a cholesteatoma and if not treated properly, may lead to development of dangerous complication in the affected ear. These etiological factors may also affect the other ear. It is therefore very necessary to assess and diagnose the contralateral ear, so that the disease can be intervened and treated at the right time, to prevent any deterioration in hearing of the contralateral ear.</p><p class="abstract"><strong>Methods:</strong> The prospective study was done in 100 patients with unilateral chronic squamosal otitis media, where the contra lateral ear was examined and assessed for any hearing loss.  </p><p class="abstract"><strong>Results:</strong> We found hearing loss in the contra lateral ear ranging from mild conductive hearing loss to sensorineural hearing loss with the maximum patients with mild conductive hearing loss (42%) and lowest in sensorineural hearing loss (1%).  </p><p class="abstract"><strong>Conclusions:</strong> In our study, 76 patients were seen with conductive hearing loss. Out of that, 42% patients were seen with mild conductive hearing loss, 30% with moderate conductive hearing loss and 4% with severe conductive hearing loss. 20% patients were seen with normal hearing. 3% patients were seen with mixed hearing loss and only 1% patient was seen with sensorineural hearing loss in contralateral ear.</p>

The conductive SISI (short increment sensitivity index) test is an indirect procedure to estimate bone-conduction thresholds for middle ear pathology patients. A series of SISI tests are run, beginning at 20 dB S.L. and increasing in 10 dB S.L. steps, until a 100% SISI score is obtained. The following equation predicts the bone-conduction threshold: [Formula: see text] The results of 25 conductive SISI tests on a conductive hearing loss group indicate that the equation approximates the measured B.C. threshold. There was no statistical difference between the predicated B.C. thresholds (12.4 dB) and measured B.C. thresholds (10.4 dB) for the group.

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.)
