The aim of this study was to evaluate the correlation between pure tone audiograms and the patients'satisfaction with tympanoplasty.
This is a questionnaire survey of patients who had tympanoplasty between 1989 and 2000.
There were 212 patients (99 male and 113 female). The median age was 56 years old. The time after surgery and the number of patients were as follows. Forty five patients were followed-up for 1-3 years. 54 patients, for 4-6 years, and 113 patients longer than 7 years.
The success rate of tympanoplasties was analyzed using the three criteria suggested by the Committee of Japan Society of Otology (CJSO)
The questionnaire was about the post operative hearing, tinnitus, otorrhea, vertigo and the results in general.
One hundred and twenty seven patients (59.9%) were aware of improvement of hearnig ; 67 patients (31.6%) no change of hearing; 11 patients (5.2%) worsened hearing;7 patients (3.3%) their good hearing same as before the operation.
According to the criteria of Japan Society of Otology, in the 127 patients who improved hearing, 113 patients (89%) were success; In the 67 patients who have no change of hearing, 44 patients (65.7%) were success; in the 11 patients who had worsend hearing, 9 patients (81.8%) were success.
Sixty four patients (30.2%) disappeared tinnitus ; 203 patients (95.7%) recognized no otorrhea;10 patients (4.7%) complained of the disturbed taste sensation; 15 patients (7.1%) complained of still continuing dizziness ; 48 patients (22.6%) complained of fullness of the ear.
The rate of patient's satisfaction was the following. 104 patients (49.1%) were satisfied with the result of the operation ; 63 patients (29.7%) were next to satisfaction;32 patients (15.1%) couldn't evaluate the operation; 13 patients (6.1%) were not satisfied.
Again according to CJSO, in the 104 patients who satisfied with the operation, 89 patient (85.6%) had a ‘success’; In the 63 patients who almost satisfied, 51 patients (81%) were ‘success’; In the 32 patients who couldn't judge the result of the operation, 21 patients (65.6%) were ‘success’; In the 13 patients who did not satisfy with the result of the operation, 11 patients (84.6%) were ‘success’.
There were thus considerable discrepancies between the subjective satisfaction and the objective findings or pure tone audiograms. There were no significant differences between the patient's satisfaction and the patient's age and the time after the operation.
The present results may indicate to include patient's subjective evaluations for assessment of tympanoplasty.
