Contrasting Shamblin classification with tumor volume in predicting morbidity and mortality in carotid body tumor resection

Background: The Shamblin classification is the standard for predicting carotid body tumor (CBT) surgical outcomes; however, its subjective nature limits prognostic accuracy. This study compared the predictive value of preoperative tumor volume vs Shamblin classification for perioperative morbidity and mortality in CBT resection at a tertiary center. Conclusions: warrants further validation as a marker of increased mortality risk, but with only one death this threshold is hypothesis-generating.
