The postoperative convalescence after tonsillectomy is difficult because of a high rate of secondary hemorrhages and severe pain. The Ultracision Harmonic Scalpel cuts in the longitudinal direction and coagulates simultaneously by means of a 55.500 Hz vibrating blade. A randomized prospective simple blind study was conceived to compare the advantages and disadvantages of the "Ultrasound Tonsillectomy" with the conventional method.
Between 8/1999 and 3/2000 25 tonsillectomies were performed with the Ultracision (TEuc-group) and 25 with conventional methods (TEkonv-group). The age of the patients was between 18 and 65 years.
The median intraoperative blood loss in the TEuc-group was significantly lower than the TEkonv-group (19.0 g/176.0 g), the pain symptoms were comparatively less. On the other hand postoperative blood losses of the TEuc-group were clearly higher (7/25 vs. 3/25), wounds healed more slowly, the development of the wound covering and the swelling of the uvula were significantly larger.
Based on the results of the study the ultrasound technique is not superior to the conventional tonsillectomy.
扁桃体切除术后的恢复过程较为困难，这是因为继发性出血率高且疼痛剧烈。超声刀沿纵向切割，并通过55500赫兹的振动刀片同时进行凝血。本研究设计了一项随机前瞻性单盲研究，以比较“超声扁桃体切除术”与传统方法的优缺点。
在1999年8月至2000年3月期间，25例扁桃体切除术采用超声刀进行（TEuc组），25例采用传统方法（TEkonv组）。患者年龄在18至65岁之间。
TEuc组术中失血量中位数显著低于TEkonv组（19.0克/176.0克），疼痛症状相对较轻。另一方面，TEuc组术后失血量明显更高（7/25对3/25），伤口愈合更慢，伤口覆盖物的形成以及悬雍垂肿胀明显更大。
基于研究结果，超声技术并不优于传统扁桃体切除术。
