Adenoidectomy is one of the most frequent operations in children. In order to reduce hospital stay costs, today, this procedure is performed as day surgery. Even though adenoidectomy is not considered risky, some minor complications may occur, the most important being bleeding (0.5-8% incidence). The surgical technique used can influence considerably postoperative pain and time to recovery. This aspect is essential in the management of day surgery patients, for whom the need of safe and rapid maneuvers associated with early recovery determines the choice of the surgical procedure. Recently, we developed a surgical technique based on the use of an electronic molecular resonance tool associated with bendable suction electrocautery. This study was carried out on 600 patients, divided into two groups, the first undergoing ablation using the molecular resonance tool and the second undergoing curette adenoidectomy. The two groups were homogeneous for age, sex, surgical indications, and grade of adenoid hypertrophy. The following parameters were considered: duration of surgery, importance of intraoperative bleeding, time to cicatrization, incidence of bleeding complications. Duration of surgery and intra- and postoperative bleeding were much lower in the first group than in the group undergoing traditional adenoidectomy. In addition, rhinopharyngeal complete cicatrization, defined as absolute absence of pseudomembrane, was much quicker in the first group, as assessed by postoperative endoscopy. Another major advantage offered by the molecular resonance tool is the accuracy of surgery performed under visual control in a practically bloodless field. To sum up, this method, thanks to its technical features and safety, is particularly indicated in children and in patients with coagulation disorders.
