Paediatric adenoidectomy: endoscopic coblation technique compared to cold curettage.

The aim of our study was to assess the efficacy and safety of endoscopic coblator adenoidectomy compared to cold curettage in paediatric patients. Forty homogeneous children (4-16 years of age) with adenoid hypertrophy were divided in 2 groups to receive adenoidectomy using cold curettage (A) or coblator (B). After surgery the following outcomes were evaluated: pain score on first day, days reporting pain, analgesic days, liquid diet days, absent from school days, pain score, days with nausea, days with fever, endoscopic adenoid grade and intraoperative bleeding. Forty days after surgery, basal rhinomanometry and nasal decongestion test were measured. The coblation group reported significantly less pain on the first post-operative day, days reporting pain, analgesic days, liquid diet days and absent school days. Patients in group A showed a higher grade of adenoid persistence by rhinoendoscopy, with high values of nasal resistances at the rhinomanometry even after nasal decongestion, consistent with greater adenoid persistence after cold curettage causing air flow obstruction even after turbinate decongestion. Intra-operative bleeding during coblation was significantly less compared the group undergoing cold curettage. Coblator treatment significantly improved patient recovery compared to curettage. Endoscopic coblation adenoidectomy ensures complete removal of adenoids and reduces postoperative adenoid grade. It can also be considered safer because it is under endoscopic control and can reach the cranial portion of the adenoid and its intranasal extension.
