Objective:
COVID-19 infection has been demonstrated to increase risk for post-operative bleeding. This study investigated the impact of COVID-19 infection on post-tonsillectomy hemorrhage in pediatric patients, a potentially devastating complication.
Study Design:
Retrospective cohort study.
Methods:
The TriNetX database was queried for pediatric patients who underwent tonsillectomy and evaluated for outcomes of primary and secondary post-tonsillectomy hemorrhage.
Results:
Among subjects 18 years and younger, 1226 were COVID-19 positive and 38,241 were COVID-19 negative in the perioperative period. There was statistically significant increased risk of bleeding with perioperative COVID-19 infection at postoperative days 1, 5, and 10. Additionally, when assessing the role of COVID-19 infection before or after surgery, the risk of bleeding remained statistically significant at all three time points, however these results did not suggest that infection before surgery confers more/less risk compared to infection after.
Conclusion:
The results of this investigation suggest that the presence of COVID-19 in the perioperative period may pose an increased risk for acute or delayed post tonsillectomy hemorrhage. This study employed a large, diverse population and is the first to address this clinical question.

Tonsillitis I: Introduction
Etiology
Three primary contributing factors have been identified.
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,...
Epistaxis
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...
