Discussion
Chronic otitis externa (COE) is a common otological problem encountered
regularly by clinicians in primary and secondary care with lifetime
incidence reported to be up to 10%. (2,6) Otolaryngologists in
secondary care often receive referrals of challenging cases of COE,
where most conventional treatments have been exhausted and failed. (2,6)
Although there have been few randomised controlled trial involving
chronic cases along with acute otitis externa, no single recommendations
can be derived for the treatment of COE as a separate clinical disorder.
