“…Combustion is a delayed effect when the irradiated power density is much higher than the characteristic power density for thermal conduction by the tissue. For soft tissue, the characteristic power density of thermal conduction is about 10 W/cm2; for bone it is in excess of/00/cm 2 [2]. In view of this explanation the numbers in Table 1 can be used as a guideline when operating.…”

The SHARPLAN laser systems are available with a full range of different powers: a 25 watt office system, a 40 watt and a 60 watt system for general surgery and an 80 watt for high power needs like neurosurgery, all powers measured at tissue. A full range of accessories is available for microsurgery enabling adaptation to the most popular surgical microscopes for cavitational surgery. Super-pulse models are available, minimizing the thermal damage to the tissue exposed to the laser. The interaction of the laser with living tissue and its specific use in neurosurgery are discussed.

In recent years neurosurgeons have shown an increasing interest in lasers. An understanding of the basic laser mechanism and tissue effects is important. CO2 laser is an excellent no-touch tool for excising and evaporating brain tumors. It has several other uses in neurosurgery both with free-hand technique and with microscope attachment and a micromanipulator. It is easier and more precise to manipulate a laser beam than any of the conventional instruments. Nd:YAG and argon lasers are more effective for coagulation of blood vessels and for dealing with vascular neoplasms. Microvascular anastamosis has been achieved with the use of Nd:YAG laser in experimental animals and has potential for practical application in extra-intracranial bypass operations. There are many advantages and some disadvantages to the use of lasers in neurosurgery.

“…Nevertheless, despite increased use of the carbon dioxide laser in tumor surgery, relatively few publications have appeared in which the details of the surgical technique are described and from which the reader can gain some general appreciation of the relative role of the laser in a large clinical experience. Most reports have specifically dealt with the laser surgery of acoustic schwannomas (13), meningiomas (1) and malignant astrocytomas (16). As our own experience with the instrument has grown, we have come to believe that the indications for use of the laser are relatively restricted and that it is best utilized as a microsurgical tool in combination with other microsurgical instruments.…”

The relative importance or utility of the carbon dioxide laser within the total context of multimodality therapy and in comparison to conventional surgical techniques is unknown. Over a 36 month period, 421 operations for tumors of the brain and spinal cord were performed in our clinic. Of these, 111 (26%) were carried out with the aid of the laser. After excluding stereotactic and transsphenoidal operations, a comparison was made between 105 laser and 216 non-laser craniotomies. With the exception of pituitary tumors, the most frequent diagnoses in both the laser and non-laser cases were the same: malignant astrocytoma (48.6 vs 33.9%), meningioma (11.4 vs 14.2%) and low grade astrocytoma (8.6 vs 8.7%). The number of reoperations in the laser group (60.1%) was higher than in the non-laser group (32.7%; p less than 0.000001) and the mean operating time (299 minutes vs 237 minutes; p less than 0.00001) was longer, but there was no significant mean difference in mortality, CNS morbidity, mean blood loss (638 ml vs 671 ml) or mean length of stay (23 vs 25 days). For the subgroup of 134 cases of malignant astrocytoma, 82% of laser procedures were reoperations versus 50% for non-laser cases (p less than 0.0002) and the mean operating time was slightly longer (p less than 0.02). The length of stay for laser cases tended to be less (21 vs 27 days; p less than 0.04), but there was again no difference in blood loss (457 ml vs 522 ml), CNS morbidity (7.8 vs 4.8%) or mortality.(ABSTRACT TRUNCATED AT 250 WORDS)
