Abstract
The objective of this paper is to compare two methods of predicting the level of subjective patient benefit following reconstructive middle ear surgery. This should have always been an important consideration in advising patients regarding surgery, but assumes even more relevance in these days of clinical audit and cost benefit analysis. The two methods studied were the ‘15/30 dB rule of thumb’ (Smyth and Patterson, 1985) and the ‘Glasgow plot’ (Browning et al., 1991). The predictions of benefit for each of the two methods were compared to the assessment of actual benefits by the patient post-operatively. The results of this comparison in 153 patients were analysed, the rule of thumb was found to be somewhat more sensitive in predicting patient benefit.
