Advantages of Coblation Adenoidectomy over Conventional Curettage Adenoidectomy

Adenoid is a patch of lymphoid tissue that is situated high up in the throat and just behind the nose in the nasopharynx. Adenoid along with the tonsils is a part of the lymphatic system that clears away infection and keeps body fluids in balance. Whenever, adenoid become enlarged, seriously infected or causes certain complications, adenoidectomy becomes essential. It can be performed with many ways including coblation adenoidectomy, conventional curettage adenoidectomy and adenoidectomy with microdebrider. The aim of this study was to assess the advantages of coblation adenoidectomy over conventional curettage adenoidectomy. This comparative observational study was conducted in the Department of ENT, Bangladesh Medical College Hospital and Popular Medical College Hospital, Bangladesh from July 2018 to December 2019. A total of100 admitted patients for adenoidectomy were included as the study. All the participants were divided in two groups. In Conventional group, there were 50 participants selected for conventional curettage adenoidectomy. On the other hand, in coblation group, other 50 participants selected for coblation adenoidectomy. For comparison of both the method all necessary data along with demographic and clinical status were collected in a predesigned questioner. All data were processed and analyzed and disseminated by using MS Office and SPSS version 23 programs as per need. In this study, as the superiority of coblation adenoidectomy over conventional curettage adenoidectomy, we found significantly lower 'intra operative blood loss in ml (7.58±3.28 ml)', 'post-operative bleeding (0.0%)', presence of residual lymphoid tissue (8.0%)', 'days with analgesics (10.42±3.60 days), 'post operative adenoid grading (0.0±0.0)', 'rate of recurrence (20.0%)' and 'needed days for recovery (4.68±2.17 days)' among coblation group patients than that among conventional group patients. Coblation adenoidectomy ensures easier and specific treatment for the patient. The findings of this study conclude that, in considering the attractive features like lower intra operative and post-operative blood loss, presence of residual lymphoid tissue, days with analgesics, post operative adenoid grading, rate of recurrence and needed days for recovery, coblation adenoidectomy may be considered as the method of choice for adenoid surgery.
