Purpose: The purpose of this study is to determine the recurrence rate of cholesteatoma in patients who have undergone exclusive endoscopic tympanoplasty at our tertiary referral institution. A secondary objective is to analyze different clinical aspects that could be considered risk factors for recurrence to establish if it is possible to determine when a second-look procedure is indicated instead of a clinical follow-up.
Methods: A retrospective study was performed on patients who had undergone exclusive endoscopic tympanoplasty for cholesteatoma in the last eight years and who were followed up for at least one year. The efficacy of the treatment performed only with the exclusive endoscopic technique was analyzed. Then, the anamnestic and intraoperative data were studied to identify possible factors that could increase the risk of recurrence.
Results: The recurrence rate (14.5%) in patients (164) who underwent primary surgery with the exclusive endoscopic technique between January 2014 and January 2022 was similar to that in patients who underwent the microscopic technique with mastoidectomy in literature. In addition, we analyzed several clinical factors such as age, ossicular chain erosion, extension and localization of the cholesteatoma finding that only the last one could potentially be a risk factor for recurrence in this selected population.
Conclusion: Exclusive endoscopic tympanoplasty has been shown to be effective in removing cholesteatoma in patients without evidence of mastoid involvement, with recurrence rates comparable to traditional microscopic technique and a minimally invasive approach, even considering the patient's age, ossicular chain erosion and extension of the disease.
