Abstract
The harmonic scalpel has been in use for tonsillectomy for the last 5–6 years in western Europe and North America. Although some studies have found this technique to be superior to other conventional methods, its use is still not very popular. In this single-blinded prospective study, the intraoperative events and postoperative morbidity after the use of harmonic scalpel in tonsillectomy (HST) was evaluated in 180 cases in two hospitals and compared with conventional steel tonsillectomy (CST) and hemostasis secured by bipolar diathermy or ligatures in 100 cases. Both bipolar diathermy and ligatures were used to control the intraoperative bleeding in all cases of CST and some cases ( n =9) of HST. The study was done in two hospitals. Patients were randomized irrespectively of their age, sex, past history or indication for surgery. The total number of patients operated on was 180 for HST and 100 for CST. The surgical duration, intraoperative blood loss and postoperative pain were compared between the patients who only had tonsillectomy done in either group ( n =120 in HST and n =70 in CST). The mean operative time in the HST group was not longer than the CST group, but the intraoperative blood loss was significantly less in the HST group. Postoperative pain was present in all patients in the HST group, but to a lesser extent than in the CST group. There was no major postoperative hemorrhage in the HST group that required surgical attention. HST has the advantage over CST when secondary hemorrhage after tonsillectomy is considered. Thus, following the results of the National Prospective Tonsillectomy Audit (NPTA), it may be safe to say that HST is superior to most other conventional methods in reducing secondary hemorrhage. The use of disposable blades in CST certainly reduces the risk of the transmission of Cruetzfield-Jacob disease (CJD).
