Background: Children with recurrent tonsillitis and tonsillar hypertrophy undergo surgical operations to correct their condition, allowing them to continue growing normally in terms of both their physical and mental development and their quality of life. Objectives: to compare and evaluate the symptoms that children under the age of 18 had following tonsillectomy, adenoidectomy, or adenotonsillectomy. The study also sought to determine how these surgical treatments influenced the children's quality of life. Methods: A thorough examination of the head and neck region was carried out on 110 patients between the ages of 3 and 15 years. The included participants' parents completed questionnaires on their children's tonsillitis frequency, medical visits, sleep patterns, absences from work or school, feelings of wellbeing, and sleep apnea three months before and three months after the surgical procedures. To formulate outcomes, a statistical examination of the obtained data was performed. Results: Adenoidectomy was used to treat 16.36% (n=18) of the 110 trial participants. Tonsillectomy was performed on 47.27% (n=52) of the study participants, and adenotonsillectomy on 36.36% (n = 40) of the participants. In the research group, sleep apnea decreased considerably from 3.01±0.98 to 0.01±0.96 (p <0.001). From three months before to surgery to three months following, there was a substantial decline in the frequency of throat discomfort and absences from school (p <0.001). With a p-value of 0.001, visits to the doctor likewise reduced from 5.08±2.12 to 0.30±2.14 visits. The sense of wellbeing also greatly improved. Conclusion: In light of its limitations, the current study finds that tonsillectomy, adenoidectomy, or adenotonsillectomy done to treat recurrent tonsillitis or tonsillar hypertrophy greatly enhances the quality of life in afflicted individuals.
