“…Therefore, Ho:YAG laser treatment also holds the risk of prolonged post-operative healing episodes (nasal crusting for 2 weeks), as described in Ref. [27,28]. Interestingly, SEM cross sections after Ho:YAG-laser treatment showed only thin coagulation zones (100 mm) within deeper layers, which were comparable to those observed after CO 2 laser treatment.…”

“…Therefore, these zones were measured and correlated to the size of the super®cial coagulation zones induced by thermal effects of the laser light. In vivo, these areas of coagulated tissue become necrotic and detach from the healthy underlying tissue in about 2±4 weeks postlaser treatment [22±25, 27,28,34,39,40].…”

“…Therefore, the laser light is mainly scattered in the surface and does not reach deeper tissue layers, producing only thin coagulation zones in the depth of the turbinates. This fact could serve to explain described post-operative bleeding episodes [27,28] if the coagulation zones do not stretch out into the depth of the tissue enough for suf®cient coagulation of blood vessels. In summary, SEM proved that Ho:YAG laser light leads to strong ablation in combination with some super®cial coagulation of the respiratory epithelium, with only minor coagulation in tissue layers beneath the ablation crater, which reduces post-operative swelling of the turbinates on one hand, but could lead to bleedings on the other.…”

In the course of this study SEM proved to be especially suitable for the examination of tissue changes on the surface of laser treated turbinates (i.g., destruction of respiratory epithelium). According to our results, Argon-ion-, Nd:YAG-, and diode-lasers seem to be useful for an effective and bloodless reduction of hyperplastic turbinates. However, broad coagulation zones may lead to consecutive complications and side effects. Due to its good ablation and superficial coagulation capabilities, Ho:YAG-laser light also seems to be usable for an effective turbinate reduction, but its low thermal effects in the depth of the tissue may lead to bleedings during treatment. Laser light of the CO(2) laser showed the lowest thermal tissue effects of the lasers investigated and therefore holds the risk of bleedings during treatment and the need of more than one therapeutic session to get a sufficient result. This investigation revealed that physicians, who are performing endonasal laser treatment, must be aware of the varying tissue effects of different medical laser systems to get a more aimed effect and to avoid intra- and post-operative complications (e.g., Rhinitis sicca, bone sequestration of the turbinate, bleedings, ...).

“…This is a tradeoff, however, as the Nd:YAG laser is very poor at vaporizing soft tissue. The Ho:YAG laser [8,9] incises soft tissue much more effectively than the Nd:YAG, but much less effectively than the CO 2 laser or Er:YAG. Soft tissue irradiated by the Ho:YAG laser also exhibits thick coagulation, but not to the extent of tissue irradiated by the Nd:YAG laser [10].…”

An experimental pathologic study of gingivectomy using dual‐wavelength laser equipment with OPO

Background and Objectives: This study was conducted to evaluate how soft tissues respond to treatment by a tunable laser with an optical parametric oscillating (OPO) mechanism capable of simultaneously emitting two wavelengths. Materials and Methods: Marginal gingiva of dogs was incised by a prototype laser oscillator. The oscillator was set at two wavelengths known to effectively incise tissue and arrest hemorrhage with minimal invasiveness. Four laser irradiation conditions were set based on different combinations of the 1.67 and 2.94 mm wavelengths. The animals were sacrificed immediately after surgery, 7 days after surgery, and 28 days after surgery for histological examination. Results: When irradiation at 1.67 and 2.94 mm wavelengths was simultaneously applied, the former conferred an observable hemostatic effect and the latter incised the tissue. Wound healing was similar to that in conventional methods and no serious inflammation was observed. Conclusion: Simultaneous irradiation at wavelengths of 1.67 and 2.94 mm can be an effective method in soft tissue surgery.
