Endaural microscopic approach versus endoscopic transcanal approach in treatment of attic cholesteatomas

Abstract

Purpose: Compare the audiological results and postoperative outcomes of the endoscopic approach versus the endaural microscopic approach for treatment of attic cholesteatomas, using a randomized prospective model.

Materials and methods: Eighty patients were consecutively enrolled in the study and randomized into two groups of treatment of 40 patients: Group A -tympanoplasty with a microscopic endaural approach; Group B -tympanoplasty with an exclusive trans-meatal endoscopic approach. Preoperative, intraoperative and postoperative outcomes were evaluated. Hearing was assessed preoperatively and at 1 month, 3 months and 6 months after surgery in both groups.

Results: There were no differences in the parameters analyzed (CT findings, patient age, disease duration, intraoperative cholesteatoma characteristics,) between the group A and B patients. No statistical difference between the two groups regarding hearing improvement, abnormal taste sensation, dizziness, post-operative pain and healing times emerged. Graft success rate was 94.5 % and 92.1 % for MES and ESS respectively.

Conclusion: Both microscopic and exclusively endoscopic endaural approaches offer similar and excellent results in the surgical treatment of attic cholesteatomas.
