Abstract
Tonsillectomy is one of the most frequent surgical procedures done worldwide. While the surgical procedure may take less than 10 minutes, there is a significant related morbidity due to per- and post-operative bleeding, post-operative pain and delayed return to normal activity and diet [1]. There is no consensus on the optimal method and device for surgery; use of cold dissection or coblation or diathermia scissors, with electro-cautery as needed; are advocated by different authors. The BIZact ™ vessel seal instrument (Medtronic, Mansfield, MA, USA) is a new technology with continuous measurements of tissue impedance, in order to deliver minimally bipolar energy for dissection and vessel sealing, with minimal thermal damage of remaining tissue [2]. The purpose of the present prospective, partly double-blinded study, was to evaluate the usefulness of BIZact for surgery in a population of adult tonsillectomy patients, in terms of: safety, bleeding, perioperative easiness and time consume, as well as postoperative parameters such as pain, resumption of oral intake, bleeding and overall satisfaction.
