Suction Diathermy Adenoidectomy (SDA) : Efficacy and Safety

Suction Diathermy Adenoidectomy : Efficacy and Safety

The aim of this prospective study is to evaluate the efficacy and safety of endoscopic suction diathermy adenoidectomy as regard the operative time, adenoid tissue remnant, blood loss, and clinical events like pain, halitosis, postoperative hemorrhage, speech changes and recurrence.

Suction diathermy adenoidectomy is a procedure that uses thermal energy generated by electric current to ablate adenoid which is removed using suction. This procedure was described in 1997 and the technique has the advantage of complete tissue removal with reduced blood loss and intraoperative time, also reduced post-operative complications as postoperative hemorrhage , nasality and lower recurrence rate.
