Impact of Adenotonsillectomy on Pediatric Blood Profiles

Objectives: Adenotonsillar hypertrophy (ATH) is a common condition in children, often leading to obstructive sleep apnea and other complications. This study aimed to evaluate the impact of adenotonsillectomy on various blood parameters in children with ATH. Materials and Methods: Medical records of 84 children diagnosed with ATH and/or chronic tonsillitis, who underwent adenotonsillectomy, were reviewed. Key parameters analyzed included white blood cell count (WBC), platelet count (PLT), hemoglobin (Hgb) levels, mean platelet volume (MPV), and platelet distribution width (PDW). Blood samples were collected preoperatively, and at postoperative day 1, week 1, and month 3, and results were compared. Results: A significant decrease in MPV, PDW, and Hgb levels was observed immediately postoperatively. Interestingly, Hgb levels significantly increased three months post-surgery, returning to or surpassing preoperative levels. Although platelet counts remained unchanged, the temporary reduction in RBC count, Hgb, and Hct levels suggests a physiological response to surgical blood loss and trauma. These parameters normalized within three months, reflecting the body’s effective compensatory mechanisms. Conclusion: Adenotonsillectomy significantly impacts certain blood parameters in the short term, with most values normalizing by the three-month follow-up. These findings emphasize the importance of monitoring hematologic changes postoperatively and suggest that adenotonsillectomy, while causing temporary alterations in blood parameters, is ultimately a safe and effective procedure for managing ATH in children.
