Prospective randomised single‐blind controlled trial of glacial acetic acid versus glacial acetic acid, neomycin sulphate and dexamethasone spray in otitis externa and infected mastoid cavities

Objectives:  The literature reports the merits of antibacterial, antibiotic and steroid agents in treating otological infections but no controlled clinical trial has directly compared 2% glacial acetic acid (EarCalm; Stafford‐Miller Ltd, Brentford, UK) against 2% glacial acetic acid, 0.1% dexamethasone and 3250 U/ml of neomycin sulphate (Otomize; Stafford‐Miller Ltd) in the treatment of otitis externa and infected mastoid cavities.
