A comparative study of two adenoidectomy technics for efficacy and safety: Conventional curettage adenoidectomy versus endoscopic microdebrider adenoidectomy

Purpose: Conventional cold curettage adenoidectomy (CCA) is the most used method for Adenoidectomy. With the advances in surgical instruments, endoscopy assisted less invasive techniques are coming into use. Herein we compared CCA with endoscopic microdebrider adenoidectomy (EMA) in terms of safety and recurrence.Methods: Patients who underwent adenoidectomy in our clinic between 2016 and 2021 years were included into the study. Study performed retrospectively. Patients operated with CCA accepted as GroupA and EMA as GroupB. Two groups compared for the recurrence rate and post-operative complications.Results: We studied 833 children aged between 3 and 12 years (mean 4,2 years old), had adenoidectomy, including 482 male(57.86 %) and 351 female (42.14 %). There were 473 patients in GroupA, and 360 patients in GroupB. Seventeen patients (%3.59) in GroupA had reoperation for the recurrence of adenoid tissue. There was no recurrence in GroupB. Residual tissue, recurrent hypertrophy, and postoperative otitis media rates were higher in GroupA, and this was statistically significant (p < 0.05). Whereas ventilation tube insertion rates didn't differ significantly (p > 0.05). Although hypernasality rate at second week was slightly higher in GroupB, this was not statistically significant (p > 0.05), and in further period it resolved in all patients. No major compli-cations were reported.Conclusion: Our study indicates that EMA is a safer technique than CCA, and prominent postoperative compli-cations like residual adenoid tissue, recurrent adenoid hypertrophy, and postoperative otitis media with effusion rates are lower.
