We followed the recommendations of the PRISMA statement for a systematic review and searched the following databases: PubMed (Medline), the Cochrane Library, EMBASE and SciELO. A predefined search strategy was used: (“Adenoid*” OR “adenoidectomy” OR “adenotonsillectomy” OR “pharyngeal tonsil”) AND (“coblat*” OR “plasma” OR “bipolar radiofrequency” OR endoscopic).Abstracts of retrieved articles were thoroughly reviewed by four authors, members of the YO-IFOS rhinology study group (CCH, BMA, XMR, MFR), and those potentially meeting the inclusion criteria were selected for full-text review. In case of discrepancies between reviewers regarding the selection of abstracts, the corresponding articles were included in the full-text review phase for final assessment. The references of all selected articles were also manually reviewed to identify any potentially missing publications.
