This study aimed to evaluate the blood parameters of children with ATH who underwent surgery. Methods: The study included a review of the medical records of 130 children who underwent adenoidectomy or adenotonsillectomy with a diagnosis of adenoid hypertrophy and/or chronic tonsillitis. Patients were classified into 3 groups: group 1 (n = 69) underwent adenoidectomy, group 2 (n = 61) underwent adenotonsillectomy, and group 3 consisted of 82 healthy children. White blood cell count, platelet count, hemoglobin levels, mean platelet volume, and platelet distribution width values were the primary outcome measures. Results: Mean platelet volume, platelet distribution width and hemoglobin values decreased in the groups that underwent surgery. Whereas the decrease in group 1 was insignificant, it was significant in group 2. White blood cell count values increased in both group 1 (adenoidectomy) and group 2 (adenotonsillectomy), but the increase in group 2 was significant. No significant difference in platelet count was detected before versus after the operation. Conclusions: Upper airway obstruction caused by ATH remarkably changes the blood parameters related to chronic hypoxia. Significant improvement can be achieved after adenotonsillectomy rather than adenoidectomy alone.eninfo:eu-repo/semantics/closedAccessMean platelet volumeplateletsupper airway obstructionadenotonsillar hypertrophyadenoidectomytonsillectomyArticle263E213E21610.1097/SCS.00000000000014372-s2.0-8495334479625933146Q3WOS:000355236700009Q4
