ABSTRACT
This study was carried out on 50 patients with chronic suppurative otitis media. They were treated with 0.5% copper sulphate together with 0.1% dexamethasone sulphate, used as ear drops on a wick placed in the external canal. The wick was removed and changed every day for 2 weeks. Aural swab was taken before and after treatment to isolate and identify the causative organisms and the response of copper therapy. Clinical and bacteriological improvement was found in most of the cases; 36 ears [27%] were dry and sterile, 32 of them were of the safe type and 4 were unsafe. Cases with post mastoidectomy infection showed no clinical or bacteriological improvement. Irritation and severe congestion occurred in 2 cases [4%] and rapidly cured by increasing the concentration of cortisone up to 0.5%
