Abstract
OBJECTIVE: To describe the Harmonic scalpel and review recent studies comparing its use in tonsillectomy with standard dissection and electrocautery. STUDY DESIGN: Review. METHODS: The Harmonic scalpel uses ultrasonic technology to cut and coagulate tissues at lower temperatures than those associated with electrocautery and lasers. Studies of the use of this device have assessed its performance with respect to intraoperative blood loss, postoperative hemorrhage, and postoperative pain. RESULTS: Intraoperative blood loss and episodes of postoperative hemorrhages have been found to be minimal in patients in whom the Harmonic scalpel was used for tonsillectomy. The device also appears to be associated with a reduction in postoperative pain. CONCLUSION: Use of the Harmonic scalpel for tonsillectomy may have several advantages over standard methods.
