The open door laminoplasty technique has been previously used to treat cervical spondylotic myelopathy. We adapted this technique for the removal of spinal tumors all along the spinal axis.


Between January 2002 and January 2003, 17 patients with various intraspinal lesions underwent open door laminoplasty. The thoracal level was involved in 10 cases, the cervical level in 3 patients and the lumbar level in 4. Location of the tumor was intradural-intramedullary in 7, intradural-extramedullary in 6 and extradural in 4 patients. The histological diagnoses were 4 astrocytomas, 2 meningiomas, 3 neurinomas, 2 ependymomas and one case each with Ewing's sarcoma, metastasis, abcess, hemangioblastoma, arachnoid cyst and lipoma.


All lesions were exposed using the open door laminoplasty technique and were successfully removed for intraspinal mass lesions. An average of 3.7 level laminoplasty was performed. Neither spinal malalignment on the coronal plane nor displacement of bone flap (laminoplasty flap) were observed on postoperative CT and MR examinations. No complications due to laminoplasty were encountered. The mean follow-up was 30 months (range 22-48 months).


Open door laminoplasty is a simple procedure and has two main advantages over the classical laminectomy procedure; a lower incidence of spinal deformities with or without neurological deficits and an absence of epidural scar tissue. This procedure can be used in all spinal cases with intraspinal mass lesions.
