[Expert consensus on techniques and material selection for dural closure in neurosurgery (2026 edition)].

To standardize dural closure techniques and material selection in neurosurgery and reduce the incidence of postoperative complications such as cerebrospinal fluid leakage, led by the Neurosurgery Branch of the Chinese Medical Association, domestic experts in neurosurgery and related fields were organized to follow the principles of evidence-based medicine and grading of recommendations assessment, development and evaluation (GRADE) system. The consensus was formulated based on a systematic review of high-quality international evidence combined with clinical practice in China. The consensus underscores the pivotal role of achieving "Watertight Dural Closure (WTDC)" and establishes a stepwise material selection strategy: prioritizing autologous tissue as the primary choice, supplemented by dural patches, and reinforced by dural sealants. For the first time, this consensus introduces a four-type morphological classification for dural incisions (Types Ⅰ-Ⅳ) and a five-grade classification for dural closure integrity (Grades A-E), upon which a quantitative risk assessment system has been established. Addressing key clinical issues, including repair material characteristics, technique application based on incision types and closure grades, site-specific repair strategies for different anatomical locations, management of special populations, and postoperative outcome evaluation, the Consensus formulates a total of 19 recommendations, aiming to provide a systematic and standardized clinical decision-making framework and operational guidance for dural repair in neurosurgery.
