N2 - Objective: To present a prospective ear surgery database and investigate the graft take-rate and prognostic factors for graft take-rate in tympanoplasty using the database.Study Design: Prospective database study.Setting: Tertiary referral center.Patients: A total of 1606 cases undergoing tympanoplasty types I to IV were registered in the database in the period from February 2004 to November 2013.Intervention: A total of 837 cases underwent myringoplasty/ tympanoplasty type I.Main Outcome Measure: Graft take-rate and prognostic factors (age, discharge at time of surgery, tuba function, technique, graft material, and revision surgery) for tympanoplasty type I were studied. A comparison with the graft take-rates for tympanoplasty types II to IV and/or cholesteatoma was made.Results: A user-friendly ear surgery database with fast data entry and direct import of audiometric data was developed. The graft take-rate was found to be 93.0% at 2 to 6 months and 86.6% at more than 12 months. Except for a discharging ear at the time of surgery, no significant differences using Χ2 test of association were found when comparing graft take-rates for different prognostic factors or more advanced tympanoplasty with or without cholesteatoma. A long-term graft take-rate overestimation of 6% was found if cases with defaulted follow-up because of early reperforation were not included.Conclusion: A prospective database can be used to study prognostic factors and reduce bias in reporting the graft take-rate. Prospective databases are needed for high-quality longitudinal studies but require a continuous and daily effort of involved surgeons and therefore need to be convenient and fast to use.
