BACKGROUND
The goal of the study was to determinate the safety of the harmonic scalpel, widely used in thyroidectomy, near the recurrent laryngeal nerve (RLN).
METHODS
The study involved ten pigs of either sex. Twenty RLNs at risk were dissected using the new harmonic scalpel FOCUS. The distances between the nerve and the activated instrument were checked with a millimeter ruler. After dissection, the pigs were euthanized, and both RLNs were fixed in formol and examined by histology after staining with hematoxylin-eosin. Due to technical reasons, only 18 RLNs from the ten pigs could be examined.
RESULTS
In the experiment that investigated the extent of heat injury, ultrasonic dissection did not cause any immediate damage of the nerve even close to the RLN (1 mm away from the RLN).
CONCLUSION
The use of harmonic scalpel FOCUS for thyroid surgery is safe for the surrounding structures (nerves). Careful tissue applications of the device near the RLN (1 mm) did not cause any lesion histologically.
背景
本研究的目的是确定广泛用于甲状腺切除术的谐波手术刀在喉返神经（RLN）附近的安全性。
方法
本研究涉及10头雌雄不限的猪。使用新型谐波手术刀FOCUS解剖20条有风险的喉返神经。用毫米尺检查神经与激活器械之间的距离。解剖后，对猪实施安乐死，将两条喉返神经用甲醛固定，苏木精-伊红染色后进行组织学检查。由于技术原因，仅对10头猪中的18条喉返神经进行了检查。
结果
在研究热损伤程度的实验中，超声解剖即使在靠近喉返神经（距喉返神经1毫米）的情况下也未对神经造成任何即时损伤。
结论
在甲状腺手术中使用谐波手术刀FOCUS对周围结构（神经）是安全 的。在喉返神经（1毫米）附近小心使用该器械，在组织学上未造成任何损伤。
