A Study On Endo-Microscopic Surgical Approach To Cholesteatoma

Introduction The surgical intervention of cholesteatoma is to eradicate the disease and to prevent the recurrence. Microscope has limited view of hidden areas of middle ear like anterior epitympanic recess and sinus tympani. Endoscope has benefits of better visualization and wide -field view of middle ear. Through microscopic approach disease in the mastoid is cleared and with the endoscope hidden areas are examined and disease is cleared without removing the posterior meatal wall. so, this combined Endoscopic and microscopic approach helps in reducing the post operative cavity complications like cavity infection, prolonged ear discharge, excessive granulations and vertigo. Objective: The objectives are to describe the steps of combined microscopic and endoscopic approach to cholesteatoma surgery, to assess the graft uptake and the hearing after surgery and to describe the reduction of post operative cavity complications with the combined approach. Results: In our study out of 30 patients 16 patients are males (53.3%) and 14 patients are females (46.6%) who underwent mastoidectomy and reconstruction with graft. Out of 30 patients, 28 patients (93.33%) graft uptake is good and in 2 patients (6.66%) graft uptake is failed and in 27 patients (90%) hearing improvement is observed and in 3 patients (10%) no hearing improvement is seen. Conclusion: Endo - microscopic approach for cholesteatoma is effective procedure in clearing the disease with reduce recurrence rate and residual disease along with no post operative cavity complications.
