Objective:
To compare the pain during the postoperative period after the extracapsular tonsillectomy, performed with the 1.94 µm laser and cold steel tonsillectomy.
Material And Methods:
Sixty patients with chronic decompensated tonsillitis were enrolled in the study. Patients were randomized into two groups: the first one was subjected to cold steel tonsillectomy; in the second group tonsillectomy was done using a laser with 1.94 µm wavelength at pulsed mode. Patients' anamnesis was evaluated (the presence of signs of a toxic-allergic form of the disease, peritonsillar abscesses, the duration of the disease and the frequency of exacerbations of tonsillitis per year). In the postoperative period patients filled out questionnaires: the severity of pain was assessed for 10 days in points from 0 to 10, and painkiller use frequency per day.
Results:
Statistical analysis revealed that the pain after tonsillectomy depends on the presence of peritonsillar abscesses in the anamnesis. In patients with abscesses, the pain and the need for anesthesia are significantly lower with the laser technique compared with cold steel. The tonsillectomy technique does not affect the risk of postoperative bleeding (in both groups - 1/30).
Conclusion:
The postoperative period after extracapsular laser tonsillectomy is characterized by significantly less pain than traditional tonsillectomy with cold instruments in patients with a history of peritonsillar abscess. Laser tonsillectomy does not have an increased risk of bleeding compared to traditional tonsillectomy.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
