Summary

The KTP-532 laser reduced blood loss during tonsillectomy but did not improve healing. Postoperative pain was initially less with conventional methods, but laser pain increased by midweek and persisted.

Use of KTP-532 laser delays healing in tonsillectomy.

Area of Science:

  • Otolaryngology
  • Laser Surgery
  • Surgical Techniques

Background:

  • Laser excision of oral lesions is claimed to reduce blood loss, pain, and improve healing.
  • Limited controlled studies exist to validate these benefits.

Purpose of the Study:

  • To evaluate the efficacy of the KTP-532 laser in tonsillectomy.
  • To compare laser excision versus conventional dissection and snare technique.

Main Methods:

  • A study involving 31 patients undergoing tonsillectomy.
  • One tonsil removed via KTP-532 laser, the other via conventional dissection and snare.
  • Blinded patient assessment of pain, healing, and intraoperative blood loss.

Main Results:

  • Intraoperative blood loss was significantly reduced with the KTP-532 laser.
  • Early postoperative pain favored conventional dissection, with laser pain increasing by midweek.
  • By one week, 63% reported more pain on the laser-treated side.

Conclusions:

  • The KTP-532 laser significantly reduces intraoperative blood loss in tonsillectomy.
  • Laser excision did not accelerate wound healing and may increase later postoperative pain compared to conventional methods.
