Clinically used drugs and chemical agents may potentially cause adverse effects to the human auditory and vestibular systems. Many of them, such as aminoglycosides and cisplatin, can play a critical role in the treatment of serious or life-threatening diseases; others, like loop diuretics or salycilates, offer such important therapeutical effects compared to the ototoxic side effects that the ototoxicity risk can be considered to be of minor importance. The problem of ototoxic side effects is more acute in developing countries, where highly effective and low-cost drugs are more easily prescribed without adequate monitoring. Medical awareness of doses, forms of administration, populations at risk, and possible synergism is necessary in order to develop appropriate care in the prescription of drugs with ototoxic side effects. Relatively recent issues such as risk-benefit analysis, patient-informed consent, and quality-of-life considerations, particularly when life expectancy can be low, are also to be considered. At present, a uniform method of monitoring for all potentially ototoxic therapeutics does not seem reasonable or practical. It is recommended, however, that individual auditory function be noted for a particular drug being employed. Protocols and exams should be easy, quick, sensitive, reliable, and as objective as possible. Benefits of audiological monitoring include the opportunity to change the patient's treatment course, improvement of patient and family awareness of the impact of hearing impairment, and timely prescription of amplification devices. Finally, particular attention should be paid to high-risk populations such as neonatal intensive care unit patients.

In the period from 1979 to 1990, a series of 59 patients with 59 acoustic neuromas were operated upon in five departments of neurosurgery by at least five different neurosurgical teams, employing the suboccipital approach. The perioperative mortality rate was 8.5%. Complications including hematoma, ventricular hemorrhage, meningitis, hemiparalysis, abducens nerve paralysis, recurrent nerve paralysis, postoperative wound infection and CSF leak were observed in 21 patients (35.6%). Radical removal of the tumor was not possible in 17 patients (28.8%). Converting the postoperative facial nerve function to the House-Brackmann (HB) classification, 34 patients (57.6%) were regarded as HB VI. Reconstruction of the facial nerve was attempted in 19 patients (32.2%). Attempts at preservation of hearing were unsuccessful in all patients. Failure to attain better results and the importance of the centralized Danish model of acoustic neuroma surgery are emphasized.
