Background and Objectives: The 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 Methods: This 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.
Results: No 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.
Conclusion: A 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.
