Abstract

Objective: To compare endoscopic assisted coblation adenoidectomy (EACA) with conventional cold curettage adenoidectomy (CCA) in terms of their impact on middle ear function postoperatively, using tympanometric evaluation.

Methods: A prospective comparative non-randomized study was conducted on 80 patients undergoing adenoidectomy aged 5–14 years. Tymanograms were recorded on postoperative day one and day seven to assess middle ear function. Parameters analyzed included tympanometric type distribution, middle ear pressure, and compliance changes over time.

Results: Initial postoperative tympanograms showed a higher incidence of Type C and B curves in the CCA group compared to the EACA group, suggesting a greater impact on Eustachian tube function. By day 7, improvements were noted in type B in both groups and all cases of type C in EACA group and some cases of CCA group , and other cases of CCA group improved after one month.

Conclusion: EACA appears to have a less detrimental effect on middle ear function postoperatively compared to CCA, likely due to reduced tissue trauma and better visualization, leading to more precise removal of adenoid tissue. Further studies with larger sample sizes and longer follow-ups are recommended to validate these findings.
