OBJECTIVE: To evaluate the hearing results and the effects of the prognostic factors following myringoplasty.
METHOD: Retrospective cohort 165 inpatients (175 ears) with preoperative conductive hearing loss were analyzed using multiple linear regression statistical analysis. They have undergone sandwich temporalis fascia myringoplasty between January 1999 and November 2003. Patients have been followed-up for more than 2 years.
RESULT: The average air-bone gap improvement for all 175 myringoplasty procedures was 7.1 dBHL. Multiple linear regression statistical analysis was subsequently carried out on these prognostic factors on hearing outcomes and yielded the following relative importance of the predictive is as follows: mean preoperative air conduction threshold, duration of dry ear, duration of disease, age. There is a strong correlation between subjective audition and pure tone threshold audiometry.
CONCLUSION: A relatively better preoperative hearing, a relatively longer duration of dry ear, a relatively shorter duration of disease and a relatively younger age were found to be significant prognostic factors influencing the postoperative air-bone gap improvement of myringoplasty. Subjective audition improvement coupled with objective pure tone threshold audiometric improvement.
