[Otosclerosis in the elderly. The effect of stapes-plasty on hearing ability and hearing aid management].

We examined 105 patients who underwent partial stapedectomies at the age of 65 years or older as treatment for combined hearing losses due to otosclerosis. Among other things investigated was the influence of the operation on the hearing of both the operated and unoperated ears, as well as on tinnitus existing preoperatively and the use of a hearing aid. Findings showed that tinnitus decreased or vanished in 75% of the cases. Sixty-one percent of the patients needed a hearing aid continuously preoperatively, with 48% not needing it post-operatively and 13% using it only occasionally. The degree of sensorineural hearing loss had by the other patients was so severe that the use of a hearing aid was also necessary post-operatively. However, in some of these cases, a successful use of a hearing aid became possible for the first time due to the surgical improvement in hearing.

Mixed hearing loss in otosclerosis: indication for long-term follow-up.

This retrospective study of 146 ears with long-term follow-up after otosclerosis surgery evaluated the stability of hearing results, the incidence of sensorineural hearing loss, and the effect of fluoride treatment. Follow-up was at least 15 years (mean, 25.2 yr; range, 15-44 yr). There were 97 large fenestra stapedectomy operations, 23 lateral canal fenestrations, 7 mobilizations, and 19 revision stapes operations. The level of air-bone gap achieved at surgery remained stable over time; the mean deterioration rate was only 0.2 dB per year. Profound sensorineural hearing loss ( > or = 65 dB bone conduction average) at the most recent follow-up occurred in 13 ears (8.9%). Such hearing loss occurred in all operative groups. Mean bone conduction average immediately postoperatively was significantly higher in these ears than in others in the study. This finding indicates that a mixed hearing loss at surgery is a factor that increases the risk of later profound cochlear loss. Only 3 percent of ears with pure conductive hearing loss, but 28 percent of patients with mixed hearing loss at surgery eventually suffered profound cochlear loss. Sodium fluoride was used to treat 11 ears with progressive cochlear loss. The rate of bone conduction hearing deterioration decreased in all ears after treatment, and none developed profound hearing loss. Follow-up after the first postoperative year is not necessary if pure conductive hearing loss is present at surgery. Annual follow-up with audiograms is recommended if a mixed hearing loss is present. Fluoride treatment is recommended if inner ear hearing loss progresses.

Effect of drinking water fluoridation on hearing of patients with otosclerosis in a low fluoride area: a follow-up study.

Fluorine content in bone samples taken from the middle ears of otosclerotic patients was determined. Otosclerotic stapes footplate was found to have a significantly higher content of fluorine than skeletal bone from the meatus. Fluorine contents in footplate and meatal wall samples of otosclerotic patients drinking fluoridated water were slightly higher than those of patients drinking low-fluoride water. In the clinical part of the study, hearing levels of 280 patients with otosclerosis living in an area with low-fluoride water were assessed. In 344 operated ears, the preoperative and long-term postoperative air conduction and bone conduction thresholds of patients drinking fluoridated water did not differ significantly from those of patients drinking low-fluoride water. After a mean follow-up period of 9.6 years, air conduction thresholds of non-operated ears in patients drinking fluoride-poor water were found to be significantly worse than those of patients drinking fluoridated tap water, likewise there were significant differences in bone conduction thresholds at 2 and 4 kHz. Thus, fluoridation of drinking water has a beneficial effect on non-operated otosclerotic ears but has no significant effect on hearing levels of operated ears.

The bone anchored hearing aid--the third option for otosclerosis.

The bone anchored hearing aid (BAHA) has mainly been used for the treatment of hearing loss in patients with congenital conductive problems or chronic suppurative otitis media. In a five-year period, 32 otosclerotic patients have been referred to the Queen Elizabeth Hospital for consideration of a BAHA. Ten of these patients have been fitted and gained benefit compared to their previous hearing aid. The benefits are not necessarily those in hearing ability but in some cases relate to cosmetic or comfort improvements. This paper demonstrates that the BAHA offers a third treatment option for otosclerosis in patients who cannot or will not undergo stapedectomy and experience difficulty with conventional hearing aids.

The effect of stapes surgery on high frequency hearing in patients with otosclerosis.

OBJECTIVE: To assess the effect of stapedectomy on high frequency hearing. STUDY DESIGN: A retrospective, one-group, pretest-posttest case review was performed of the audiometric data of patients who underwent stapedectomy at a tertiary referral center. PATIENTS: Thirty-eight patients (40 ears) with primary uncomplicated surgery were selected. Twenty-two of the patients were older than 40 years. Preoperative and postoperative audiograms were analyzed. RESULTS: Preoperative and postoperative audiograms exhibited a down-sloping configuration toward the high frequencies. Surgery resulted in a significant improvement (p < 0.05) from 500 to 4000 Hz in air conduction and 500 to 2000 Hz in bone conduction. Analysis of variance showed that age had no bearing on preoperative audiometric results (p < 0.05) for air conduction, bone conduction, and the air bone gap. Postoperatively, younger patients' 4000 to 8000 Hz (air conduction) and 4000 Hz (bone conduction) were better than those of the older patients (p < 0.05), but the high frequency range was still poorer than age-matched controls in the younger patients. CONCLUSION: Stapedectomy resulted in significant closure of the air bone gap between 500 to 4000 Hz, but failed to influence hearing above 4000 Hz. Age appears to be an important variable; poorer results in the high frequency range were seen in the older patients who underwent stapes surgery. These findings, together with the residual postoperative hearing loss in the high frequency range in young patients, may reflect disease-specific injury resulting from cochlear otosclerosis.
