Abstract

Introduction: Adenoidectomy is one of the most commonly performed operation worldwide. Most widely used approach for surgery is conventional curettage method. However, as this method is associated with high incidence of residual adenoid tissue at the end of surgery which results in recurrence of disease, a newer endoscopic microdebrider assisted approach is becoming popular these days. Though various studies have shown its efficacy in more complete removal of adenoids, its functional outcome on middle ear function remains to be explored. Objectives: To compare pre and post operative pure tone audiometric and impedance audiometric analysis following conventional and endoscopic micodebrider assisted adenoidectomy. Materials and Methods: Patients were diagnosed cases of chronic adenoiditis which were divided in groups of 25 each. Patients in first group underwent conventional curettage adenoidectomy while in second group patient underwent endoscopic microdebrider assisted adenoidectomy. Pre and postoperative pure tone and impedance audiometry were performed for all the patients and the outcomes were compared. Results: Endoscopic microdebrider assisted method resulted in better outcomes which were statistically significant as compared to the conventional curettage. Criteria such as hearing threshold (p value 0.004 at second follow up), peak pressure (p value 0.045 at first follow up), tympanogram (p value 0.016) showed that endoscopic method was better while peak compliance (P value 0.340 at first follow up) didn’t show any significant difference between the groups. Conclusion: Endoscopic microdebrider assisted method of adenoidectomy has a definite advantage of better visualization and results in more complete removal of tissue and hence results in better improvement in middle ear functions as compared to the conventional curettage.
