“…2 New laser system being used in many clinical fields has been known to have a good accuracy and proper thermal energy delivery to ablating tissues. 6 Diode laser system is one of the surgical instruments that is widely applied in many clinical departments. Recently, 1,940-nm laser system has been developed and the first was used in prostate surgery.…”

“…Many studies have proven that a 1,940-nm emission wavelength overlaps with one of the water absorption peaks. [6][7][8][9][10] The absorption coefficient of 1,940-nm laser is very high and this enables the 1,940-nm laser to ablate tissue more precise with less thermal damage. 6 Guney et al 6 reported that hemostatic effect of 1,940-nm is superior to other types of inferior turbinate surgery.…”

“…5 1,940-nm laser has a high water absorption rate of the tissue and it enables the 1,940-nm laser to handle tissues more precise with low thermal damage. [6][7][8][9][10] However, there is no report about the clinical trial in Korean patients with inferior turbinate hypertrophy using 1,940-nm thulium fiber laser system. Therefore, this study is conducted prospectively to evaluate the clinical feasibility of 1,940-nm laser in the treatment of Korean patients with inferior turbinate hypertrophy.…”

Background and ObjectivesThe purpose of this clinical feasibility trial was to evaluate the preliminary results regarding postoperative outcomes of inferior turbinate reduction using a 1,940-nm thulium laser system. Materials and MethodsThis clinical feasibility trial included eight patients with inferior turbinate hypertrophy. The inferior turbinate reduction was performed using a 1,940-nm thulium laser with 4.5 W of output power. Intraoperative scoring was performed by a surgeon rating the ablative capacity of the apparatus ResultsNo complications were observed in this study. The surgeon's mean rating on the ablative capacity of the laser was 4.13 ± 0.35. Postoperative pain decreased prominently (4.13 ± 2.10, 1.38 ± 1.19, 0.25 ± 0.46 on postoperative day one, week one, and week two, respectively) with a statistically significant difference observed between postoperative day one and week two [p=0.0005]. Swelling on postoperative day one had decreased significantly by postoperative week one [p=0.001]. Scar contraction score on postoperative day one had decreased significantly by postoperative week one [p=0.003]. ConclusionThe 1,940-nm Thulium fiber laser system is an efficient alternative to conventional laser systems in the treatment of nasal congestion due to hypertrophied nasal turbinates. Further randomized comparative clinical trials are needed to confirm these results and to extend the 1,940-nm laser-energy application in the clinics.

“…In otorhinolaryngology, several studies have shown the efficacy of a 1940 nm laser in various procedures specific to this field: [16][17][18] Guney et al reported on the ablation efficacy of a 1940 nm laser in intraoral surgery. 6 Considering that the output wavelength Female 15 4 0 0 0 2 24 Male 25 4 0 5 2 3 20 Male 25 5 1 2 4 4 45 Female 20 5 0 1 1 5 20 Female 20 5 0 1 1 6 21 Male 32 3 of a 1940 nm laser coincides with water's absorption peak, a flexible application is possible with a fibertype laser; its clinical application could also be further widened, especially in the field of otorhinolaryngology with its evident anatomical complexities. Moreover, in regards to intraoral soft tissue operations, we believe that a 1940 nm laser is advantageous for the following reasons: 1) it is user-friendly, 2) has good cutting power, 3) induces relatively good coagulation, and 4) shows less collateral tissue damage.…”

“…They can be used to produce immediate and precise tissue destruction in a bloodless manner, forming an incision or ablation with minimal thermal damage to the surrounding, healthy tissue. 6 Such properties allow lasers to be used with ease in the surgical treatment of vascular lesions, while rendering pharmacological therapy unnecessary for patients with coagulation problems. Moreover, the incisions are self-sterilizing and are formed with minimal tissue distortion while the sealing ability of the laser provides a bloodless dissection.…”

Background and ObjectivesThe aim of this clinical feasibility study was to assess preliminary results regarding postoperative outcomes of tonsillectomy using a laser system emitting at 1940 nm. Materials and MethodsThis clinical feasibility trial included six patients suffering from chronic tonsillitis. Tonsillectomy was performed using a 1940 nm laser with 6 W of output power. Intraoperative scoring was performed by a surgeon rating the cutting capacity of the device (5 point scale, 1-5), as well as intraoperative bleeding (3 point scale, 0-2). Patient surveys of pain and the surgeon's reports on postoperative changes in the surgical field (11 point scale, 0-10) were also analyzed on postoperative day one, and after week(s) one and two. ResultsNo complications were observed in patients. The surgeon's mean rating on the cutting capacity of the laser was 4.33 ± 1.96. Bleeding was almost absent, with a mean blood loss of 2.3 ml. Postoperative pain abruptly decreased after postoperative week one (4.83 ± 2.23, 3.33 ± 2.65, 1.17 ± 0.75 at postoperative day one, week one, and week two, respectively), with a statistically significant difference observed between postoperative day one and week two (p=0.008). Two patients required additional pain relief for five days after postoperative week one. Swelling had decreased significantly by postoperative week one (p=0.004), with a score of nearly 0 by postoperative week two. The mean scores for changes in scarring were 4.83 ± 0.40, 2.83 ± 1.21, and 1.67 ± 2.07 at postoperative day one, week one, and week two. ConclusionA 1940 nm laser demonstrated excellent intraoperative performances and postoperative outcomes in tonsillectomy. In addition, conduct of more large-scale and comparative studies is warranted in order to elucidate the efficacy of this laser treatment for tonsillectomy. Key words
