Magnitude of impacted earwax in Oman, its impact on hearing impairment and economic burden of earwax on health services
Background : Wax in ear canal causes a sizeable burden on resources of
health services to a country. Aim :The magnitude of impacted wax, its
effect in a survey and cost of managing this problem were reviewed in
2002. Settings and Designs :A study was conducted during1996 to
estimate the magnitude and causes of hearing impairment and ear
diseases in Oman. The authors further reviewed the data of
community-based prevalence study to assess the role of impacted wax.
Materials and Methods: Trained physicians used portable audiometers to
test the hearing status of each ear. They used otoscopes to examine the
ear. Persons suspected to have hearing impairment or ear disease were
reexamined by audiologists and otologists to determine the causes of
hearing impairment. The resources for managing impacted wax were also
calculated. Results : In this survey, 11,402 subjects of all ages were
examined. Prevalence of impacted wax was 11.7% (CI 95% 11.1-12.2).
Impacted wax was significantly higher in females compared to males [RR
= 1.22 (CI 95% 1.10-1.35)]. It was more common in residents of regions
with humid environment than those of regions with less humidity [RR =
1.91 (CI 95% 1.67-2.18)]. Impacted wax in ear canal was associated with
ear diseases. A total of 181,000 Omani people were estimated to have
impacted wax in the ear canal. Managing impacted wax could cost 3.6
million US dollars to the ear care services. Conclusions : Impacted
wax was a hindrance in the hearing survey, and countries should plan to
deal with earwax in such surveys. Its impact on hearing impairment and
resource burden should be considered while formulating polices for ear
care
