title: Burow's solution in the treatment of active mucosal chronic suppurative otitis media: determining an effective dilution.
abstract: Burow's solution (13 per cent aluminium acetate) has been found to inhibit in vitro the growth of most commonly occurring bacteria found in the discharging ear. An in vitro study has shown that the minimum inhibitory concentration of Burow's solution for these organisms lies between a 1:80 and a 1:160 dilution. This paper reports on a clinical trial that incorporated 67 discharging ears to establish the most effective strength of aluminium acetate solution. There was no statistical difference in the effectiveness of full strength Burow's solution compared to 3.25 per cent aluminium acetate solution (a quarter strength Burow's solution). Response rates of 80.8 per cent and 75 per cent respectively following a two-week treatment period were achieved using these two solutions. A 1.3 per cent aluminium acetate solution (1/10 strength Burow's solution) was found to be markedly inferior. Bacteriological and audiological profiles were recorded for each patient.
