Objectives:
To identify the risk factors for post-tonsillectomy hemorrhage (PTH) in adult patients (>19 years).
Methods:
275 adult patients who underwent tonsillectomy between 2009 and 2019 were retrospectively analyzed. Possible risk factors associated with PTH were investigated by univariate and multivariate logistic regression analyses.
Results:
PTH occurred in 39 of 275 patients (14.2%). Regarding underlying diseases, PTH occurred more frequently in focal infection of IgA nephropathy. Furthermore, bipolar electrocautery was the other risk factor for PTH on multivariate analysis.
Conclusion:
Focal infection of IgA nephropathy and bipolar electrocautery were identified as the risk factors for PTH.

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,...
