Background and ObjectivesTonsillectomy is a painful procedure that often results in severe pain, postoperative hemorrhage, and swallowing difficulties, jeopardizing the quality of life in patients. We aimed to investigate the effectiveness of the 1940-nm diode laser method compared with the more commonly used electro-cauterization method for tonsillectomy.
Materials and MethodsTwenty-two patients, who underwent tonsillectomy for chronic tonsillitis, were prospectively analyzed. Tonsillectomy was performed using either a 1940-nm laser with 12 W of power or the conventional electro-cauterization. Patients were randomly assigned to one of the two groups. A 5-point scale (1-5) was used to measure the intraoperative score via the cutting capacity of the device, and a 3-point scale (0-2) to measure intraoperative bleeding (3-point scale, 0-2). Patients' surveys on pain and the surgeon's reports on postoperative changes in the surgical field, such as edema and scarring, were also analyzed (11-point scale, 0-10) on postoperative one day, one week, and two weeks, respectively.
ResultsThe mean operative time was 22.6 minutes. Operation time, cutting capacity, and intraoperative bleeding were not significantly different between the two groups. Pain scores of patients for the laser group were significantly reduced compared with that of electro-cautery group at one week, even if the surgeon's assessments of scar contraction and swelling were not different between the two groups. Moreover, there was less destruction of tonsil tissues in the laser group according to the histological evaluation.
ConclusionA 1940-nm diode laser demonstrates excellent intraoperative performance that is similar to the conventional device. Postoperatively, a notable reduction in pain score on postoperative one week was elicited in patients using 1940-nm diode laser.
