根尖周病变范围对显微根尖手术影响的分析与处理OA

Endodontic microsurgery is a critical treatment option that is often considered when conventional root ca-nal therapy fails or when complex periapical diseases cannot be resolved through non-surgical treatment.The clinical out-comes of endodontic microsurgery are influenced by multiple factors.Among these,the size of the periapical lesion is considered a key variable that can significantly impact surgical design,operative difficulty,postoperative infection con-trol,and tissue healing.This article systematically discusses the mechanisms by which the size of periapical lesions af-fects the efficacy of endodontic microsurgery,preoperative assessment methods,intraoperative management strategies,and prognostic correlations.On the basis of existing evidence from evidence-based medicine,clinical management re-commendations are proposed to provide a theoretical foundation and operational guidance for clinical practice.
