Abstract

 Background: Treatment of tonsillitis is necessary when the inflammation recurs repeatedly in order to prevent potential complications. Surgical removal is an effective treatment option that is also low-cost. CO₂ laser in surgery have been shown to effectively control bleeding, serving as both a precise surgical blade and coagulation tool for hemostasis. Objectives: To describe clinical and subclinical characteristics, evaluate treatment efficacy, and understand some factors related to postoperative pain among patients undergoing tonsillectomy using CO₂ Laser. Materials and methods: Prospective cross-sectional description with intervention on 74 patients who was diagnosed with chronic tonsillitis and underwent CO₂ laser tonsillectomy at Xuyen A Vinh Long Hospital from 2023 to 2024. Results: There were 74 patients who were prescribed CO₂ laser tonsillectomy, including 35.1% male and 64.9% female. Between the ages of 5 and 59 years, the mean age was 34.28 ±12.73. All patients had overall postoperative outcomes as well. The inflammatory tonsil morphology consists of atrophic fibrosis (63.5%); hypertrophy (24.3%); atrophic fibrosis with purulent cavities, pox seborrhea (10.8%); hypertrophy with pus cavities, pox residue (1.4%). Most patients lost less than 5 mL of blood, accounting for 58.1%. The average length of a patient’s stay in the hospital was 2.88 ± 1.40 days; the average time to resume normal eating was 8.77 ± 2.04 days, and the average time to return to normal living was 6.08 ± 2.37 days. Factors statistically significantly related to the level of postoperative pain included symptoms of fatigue, an itchy throat, tonsil congestion, the progression of the tonsil cavity, and the condition of the postoperative surgical pit. Conclusion: Recurrent fever, sore throat, and proliferation of lingual and pharyngeal lymphoid tissues were the most common symptoms. Most patients had grade III and IV tonsillar hypertrophy. CO₂ laser treatment for chronic tonsillitis provides good therapeutic results in all patients regardless of the degree of hypertrophy. It helped reduce blood loss and shortens postoperative recovery time.
