Quality-of-life outcomes with endoscopic and microscopic type I tympanoplasty-a prospective cohort study

Endoscopic type I tympanoplasty was originally introduced in the 1990s and the extensive spread of this practice can be easily observed. The conventional technique performed involves the repair of a tympanic membrane perforation and is defined as microscopic type I tympanoplasty. The aim of this study is the comparison of quality-of-life (QoL) outcomes with endoscopic to that with microscopic type I tympanoplasty.

All patients, or in the case of children with the aid of a parent, were asked to complete a novel QoL questionnaire drafted by our study group. The analysis was performed with descriptive statistics-mean, SD and relative frequency-and with a mixed model (generalized least squares fit). A two-sided p value of < 0.05 was regarded as statistically significant.

A total of 83 patients completed the questionnaire, 38 in the endoscopic group and 45 in the microscopic group. Every question represented a different. A statistically significant result was found in favor of the endoscopic approach regarding average hospitalization rate (p = 0.003) and cosmetic outcomes (p = 0.015). No statistically significant difference was otherwise observed between the groups.

Based on our prospective cohort study, the QoL outcomes of endoscopic type I tympanoplasty in terms of postoperative pain, headache, nausea, vomiting, dizziness, taste disorder and hearing were comparable to the microscopic type I tympanoplasty. In regard to cosmetics, an increase in desirable results was achieved in the endoscopic group, particularly the average hospitalization rate proved to be statistically significantly lower than in the microscopic group.
