Abstract
Most studies regarding residual and recurrent cholesteatoma focus on single relapse. This study examines patients who had to undergo at least three surgeries for complete eradication of their cholesteatoma, with the aim of bringing to light risk factors and assessing the functional impact of multiple surgeries on hearing. We include 27 patients who underwent 3 consecutive surgeries for cholesteatoma between 2006 and 2016. This population represented 3.1% of all cholesteatoma operated on during that same period (868 patients). Cases of multi-residual and/or recurrent cholesteatoma (RRC) were significantly younger (13.1 years old), than single-RRC or cases with No-RRC (respectively, 28.0 and 38.5 years old) (p < 0.01). Furthermore, there was a significant difference in cholesteatoma location especially for combined attical and mesotympanic location between the three groups (no-RCC 26%; single-RRC 34% and multi-RRC 66%) (p < 0.01). There was also a significant difference in ossicular erosion of the malleus, incus and stapes between the three groups (p < 0.01). In our study, the type of surgery did not influence multi-RRC rates. We did not observe any significant impact on hearing between the first and third surgeries. Mean duratio...Continue Reading
