Granulation tissue after otologic surgeries: a cross-sectional report on the incidence and management

Abstract

Background Granulation tissue (GT) formation is a complication of otologic surgeries. We aimed to assess the rate of GT formation following these procedures and their outcome. Methods This cross-sectional study was performed from 2015 to 2019. Patients who underwent tympanomastoidectomy (either CWD or ICW) and stapedotomy were included. Demographic and other related data were gathered. Four weeks after surgery, patients were assessed for any sign of granulation tissue formation. If present, they were managed topically and were followed every 2 months until complete resolution. Results Of 1045 included cases, 200 underwent Canal Wall Down (CWD) mastoidectomy, 568 underwent Intact Canal Wall (ICW) mastoidectomy, and 277 experienced stapedotomy. Four weeks after surgery, 180 participants were diagnosed with GT (17.22%). The incidence rate of GT formation following tympanomastoidectomy and stapedotomy is 23.44% and 0%, respectively. This measure is 43% and 16.5% for CWD, and ICW approaches. Following treatment for 2 months, we found 164 (91.1%) participants with complete resolution at the second visit. Of the remaining 16 cases, 10 and 6 were cured at the third and fourth visits. Males developed GT significantly more (p < 0.001). Conclusion Those with CWD mastoidectomy are more likely to develop GT than ICW and stapedotomy surgeries. It has a favorable response to conservative topical management.
