Background and Objectives:Chronic ear surgery is one of the most comon procedures performed for hearing gain. The two Benefit Plot. Few studies in the literature have reported hearing results by the Glasgow benefit plot method. The purpose of this study is to evaluate the degre of binaural hearing benefit after chronic ear surgery by the Glasgow benefit plot method. Materials and Method:Sixty-five records were selected from database of 1300 chronic ear surgery performed from 1989 through 2001. All subjects had bilateral hearing loss greater than 30 dB hearing level and could be followed up audiometrically longer than 12 months after the surgery. Results: (inter-aural diff-erence ≤10 dB in air conduction threshold) was achieved in 40% of the subjects (26/65), and better hearing (>10 dB in air conduction threshold better than those of non-operated ear) was achieved in 25% of the subjects (16/65). Conclusion:The Glasgow benefit plot method is a useful method for evaluating subjective benefit of binaural hearing in bilateral chronic otitis standpoint rather than in purely technical terms.
