RESUMO
OBJECTIVES: This study aims to compare results of endoscopic transcanal tympanoplasty with attico-antrostomy with endoscopic-assisted canal wall up mastoidectomy in treatment of cases of limited attic cholesteatoma. MATERIALS AND METHODS: A prospective randomized single-blinded study involving 40 patients with limited attic cholesteatoma was conducted. Randomization of the patients into two groups was done; 20 patients are managed by endoscopic transcanal tympanoplasty with attico-antrostomy, while the other 20 patients are managed by endoscopic-assisted canal wall up mastoidectomy. Primary outcome is recidivism, while secondary outcomes include hearing results, operative time, pain score and associated complications. RESULTS: Comparable recidivism rate was found in the two groups. The endoscopic-assisted canal wall up mastoidectomy group was associated with significantly longer duration of surgery and higher postoperative pain score. There was no significant difference between both the groups regarding hearing results and associated complications. CONCLUSION: In localized attic cholesteatoma cases, endoscopic transcanal tympanoplasty with attico-antrostomy is a time-saving less-invasive reliable technique with good eradication results.
