The laser, with its ability to use electromagnetic energy in its most efficient and concentrated form, has held out promise as a surgical tool for 20 years. However, its early promise has not been fulfilled, and with a few isolated exceptions, the laser has not gained widespread acceptance in surgical circles. Recent developments regarding delivery systems and different lasing media have, however, stimulated renewed interest. Similarly, cryosurgery, with its ability to devitalize tissues by the use of extreme cold, has been available in a controllable form in surgery for nearly 30 years. Lack of precision has prevented its widespread use, but it may still have an important role in a number of specialized areas, such as cryoneurectomy and the management of locally aggressive tumors of bone.
激光能够以最有效、最集中的形式利用电磁能，在过去20年里一直有望成为一种外科手术工具。然而，它早期的前景并未实现，除了少数个别例外情况，激光在外科领域并未得到广泛认可。不过，最近在传输系统和不同激光介质方面的进展激发了新的兴趣。同样，冷冻外科能够通过使用极冷来使组织失去活力，以可控形式应用于外科手术已近30年。缺乏精确性阻碍了它的广泛应用，但在一些专业领域，如冷冻神经切除术和骨局部侵袭性肿瘤的治疗中，它可能仍发挥重要作用。
