Economic viability of stapes surgery in Germany.
OBJECTIVE
The purpose of this study was to determine the economic viability of stapes surgery in Germany. We compared the cost of the operation to the retail value and average cost of a lifelong supply of hearing aids.


METHODS
Retrospective study.


METHODS
Tertiary referral centre.


METHODS
One hundred and sixty-four consecutive cases of primary stapedotomy performed on patients with otosclerosis at our institution served as the representative group for the calculation. The post-operative air-bone gap average at the frequencies 500, 1000, 2000 and 4000 Hz was less than 10 dB for 62 per cent of the patients, and less than 20 dB for 92 per cent of the patients. There was a post-operative sensorineural hearing loss in 1.2 per cent of the patients.


RESULTS
Analysis showed that, even for an elderly patient aged 65 years with a life expectancy of 15 years, the cost of a lifelong supply of hearing aids was greater than that of a stapedotomy procedure. Based on our group of patients, the stapedotomy procedure proved to be euro 800,000 K cheaper than treatment with an averagely priced hearing aid. The economic benefit was still present when taking into account possible revision surgery in 5-10 per cent of cases, and also when, in addition to the surgery, a post-operative hearing aid was required, in for example 20 per cent of cases.


CONCLUSIONS
Stapes surgery is economically beneficial for the individual patient as well as for the general patient cohort, irrespective of age. The stapedotomy procedure also prevents the known disadvantages of conventional hearing aids, thus improving the patient's quality of life.
