Ultrasonic partial glossectomy.

Abstract

INTRODUCTION: Partial glossectomy is the main treatment for tongue carcinoma. The resection of the tongue, which is a very vascularised tissue, requires a good hemostasis. The advantage of the harmonic scalpel is in combining sectioning and hemostasis in one single instrument, allowing a bloodless dissection of soft tissue. The aim of this prospective study was to evaluate the benefits and risks when using a harmonic scalpel in partial glossectomy. SUBJECTS AND METHODS: In this prospective study conducted in a university hospital from march 2004 to December 2008, eighteen consecutive patients underwent a partial glossectomy with the use of harmonic scalpel. Results were compared with previous surgical procedures performed between September 2000 and February 2004 by monopolar hemostasis by our team (n = 12) when the harmonic scalpel was not available. RESULTS: All 18 patients underwent partial glossectomy with the harmonic scalpel as the only instrument of section and hemostasis. The median blood loss was of 0 mL. The median operative time was 29 minutes (16 minutes less than partial glossectomies performed with conventional hemostasis. P < .001). No operative complications occurred. Two post-operative bleedings (5 days and 7 days after the glossectomy) occurred necessitating a new surgery to ligate the lingual artery. The margins of the resection were acceptable and no recurrence appeared. CONCLUSION: The harmonic scalpel makes it fast and easy to perform a partial glossectomy with no bleeding. Ligation of the lingual artery (when it is visualized during the dissection) should be performed because of the frequency (more than 10% in our series) and because of the potential gravity of a lingual post-operative bleeding.
