Currently, decompressive laminectomy with or without concomitant fusion is a standard treatment for ossification of the ligamentum flavum (OLF). However, conventional thoracic decompressive laminectomy is not free of the inevitable destruction of the posterior ligamentous complex, and facet injury may lead to various sequelae.
We used the biportal endoscopic technique for posterior thoracic decompression (BE-PTD) and describe the steps with discussion regarding the indications, advantages, possible complications, and ways to overcome complications.
BE-PTD can obtain endoscopic visualizations of all the boundaries of the OLF lesion and achieve direct neural decompression of thoracic OLF.
目前，伴有或不伴有融合的减压性椎板切除术是治疗黄韧带骨化（OLF）的标准方法。然而，传统的胸椎减压性椎板切除术不可避免地会破坏后韧带复合体，且小关节损伤可能导致各种后遗症。
我们采用双门内镜技术进行胸椎后路减压（BE-PTD），并描述其步骤，同时讨论适应证、优势、可能的并发症以及克服并发症的方法。
BE-PTD能够在内镜下观察到OLF病变的所有边界，并实现对胸椎OLF的直接神经减压。
