Comparison of the effects of coblation and curettage adenoidectomy on adenoid regrowth

Aim: To investigate whether there is a relationship between coblation and curettage adenoidectomy techniques in adenoid recurrence.Material and Methods: An electronic medical database was used to identify the records of 84 children who were performedadenoidectomy without tonsillectomy between January 2016 and January 2019. Patients who had adenoid hypertrophy without ahistory of revision surgery and underwent coblation or curettage adenoidectomy without tonsillectomy were included in the study.Operation notes were recorded. Adenoid regrowth was evaluated by flexible nasal endoscopy in patients who completed at least a1-year follow-up period.Results: 51 and 33 patients met the inclusion and were comprised of coblation and curettage groups, respectively. The meanoperative time was 14.5±5.1 min in the curettage group and 23.3±11.4 min in the coblation group (p=0.001). The mean intraoperativeblood loss was 5.75±3.6 ml in the coblation group, and 11.58±7.2 ml in the curettage group (p=0.007). At the end of a 1-year followupperiod, adenoid regrowth rate was observed in 5.66% in the curettage group and 2% in the coblation group and this differencewas statistically significant (p=0.027).Conclusion: Coblation adenoidectomy represents a reliable and highly effective method that has a low incidence of regrowth andless intra-operative bleeding but has a longer operation time in comparison with conventional cold curettage adenoidectomy.
