In-the-canal hearing instruments. Benefits and problems for inexperienced users given minimal instruction.
The number of in-the-canal hearing instruments (ITC) distributed annually in our region is increasing. The purpose of this investigation, which included 300 persons, was to evaluate the problems and benefits reported by ITC users who had received a minimum of counselling. Another aim was to decide which factors to concentrate on when teaching local health personnel how to assist hard-of-hearing equipped with ITC. The results showed that 38% had operational difficulties, 63% had experienced untoward sound reception. However, almost 90% reported positive experiences and the overall result for more than 80% was good. Operational difficulties resulted mainly from insufficient instruction. A moderate degree of instruction at the check-up was both essential and beneficial. Untoward sound experiences were caused mainly by inadequate venting and/or inaccurately adjusted instruments, faults that could be easily dealt with. It is therefore essential to teach local health service personnel that clients initially reporting problems in using their ITC can in most cases have their problems solved, mainly by simple instruction and/or an adjustment of the ITC. Only when these measures have failed should other types of hearing instruments (HI) be tried. Local health service personnel should therefore be instructed not to accept initial rejection of ITC merely because of the small size of the instrument until further instruction has been given, and not proved successful.
