A comparative study of BiZact? tonsillectomy versus cold steel dissection technique in adults: Analysis of operating time, intraoperative blood loss, postoperative bleeding rate and pain

ObjectivesTo analyse operating time, intraoperative blood loss, postoperative bleeding rate and pain when using the relatively new BiZact (TM) tonsillectomy device compared to the commonly used cold steel dissection technique with bipolar cautery in adults.DesignRetrospective case control study. Parameters analysed for significant association with technique were operating time, intraoperative blood loss, wound pain on postoperative days 1-4 and rate of post-tonsillectomy bleeding (PTB).SettingMonocentric study at a department of otolaryngology and head and neck surgery at a tertiary centre in Germany.ParticipantsA total of 183 patients who underwent a bilateral tonsillectomy with either the BiZact (TM) tonsillectomy device or the cold dissection technique with bipolar cautery for haemostasis.Main Outcome MeasuresOperating time, intraoperative blood loss, postoperative pain on the first to fourth postoperative day (numeric rating scale: 0-10) (PTB, primary bleeding <= 24 h, secondary bleeding >24 h postoperative; Stammberger scale).Results and ConclusionThe BiZact (TM) tonsillectomy device leads to a significant shorter operating time with less intraoperative blood loss compared to cold steel dissection with bipolar haemostasis. No benefits with regards to PTB or postoperative pain could be observed. The use of the BiZact (TM) device provides major benefits in clinical routine and stands up to conventional tonsillectomy techniques.
