The cervical laminectomy is usually applied in the treatment of cervical myelopathy caused by cervical canal stenosis and multiple spondylosis. Nevertheless, late complications are often reported, especially scar formation, the so-called laminectomy membrane, between the dura and overlying paraspinal muscles, which, compressing the cord, reduces until to abolish the favourable effects of the previous laminectomy; moreover, malalignment of the cervical spine with secondary kyphosis may follow an expansive laminectomy. In order to avoid these complications, in 1977 Hirabayashi introduced a new surgical technique, the "expansive open-door laminoplasty", which permits the enlargement of the spinal canal over multiple segments by completely incising the laminae laterally on one side and partially on the opposite: elevation with tilting of the laminae upward in the incised side, allows enlargement of the canal. The Authors describe in detail the operative procedure and report their experience in 10 patients.
颈椎椎板切除术通常用于治疗由颈椎管狭窄和多节段脊柱病引起的颈椎脊髓病。然而，晚期并发症经常被报道，尤其是硬脊膜与覆盖其上的椎旁肌之间形成的瘢痕，即所谓的椎板切除膜，它压迫脊髓，会减弱直至消除先前椎板切除术的良好效果；此外，扩大性椎板切除术后可能会出现颈椎畸形并继发后凸。为了避免这些并发症，1977年平林介绍了一种新的手术技术，即“扩大开门式椎板成形术”，该技术通过在一侧完全切开椎板并在另一侧部分切开，允许在多个节段上扩大椎管：在切开侧将椎板向上抬起并倾斜，从而扩大椎管。作者详细描述了手术过程并报告了他们在10例患者中的经验。
