Although a maxillary nerve (MN) block reportedly provides satisfactory analgesia for midface surgery and chronic maxillofacial pain syndromes, a safe and reliable MN block technique has not been reported. The goal of this anatomical study was to quantify the various angles and depth of the block needle, as well as to evaluate the impact of volume on the extent of injectate spread that might influence anesthetic coverage and block-related complications.

超声引导的上颌神经阻滞：使用the上go突入路的解剖学研究

尽管据报道上颌神经（MN）阻滞为中脸手术和慢性颌面部疼痛综合征提供了令人满意的镇痛效果，但尚未报道安全可靠的MN阻滞技术。这项解剖学研究的目的是量化阻滞针的各种角度和深度，并评估容量对可能影响麻醉剂覆盖率和阻滞相关并发症的注射扩散程度的影响。
