The barrier effect of laminae: laminotomy versus laminectomy.
METHODS
An experimental study to investigate whether replacement of the laminae (laminotomy) after subliminal procedures can prevent the invasion of scar tissue towards the dura.


METHODS
Izmir, Turkey.


METHODS
Laminectomy and laminotomy were performed at different levels on seven rats. Their spinal columns were investigated histopathologically after a period of 3 months.


RESULTS
The histopathological evaluation revealed that the dura and spinal cord were involved by scar tissue at laminectomy area. However, this invasion was not observed at laminotomy levels. This study showed the barrier effect of laminae against fibroblastic activity.


CONCLUSIONS
The barrier effect of lamina may affect the surgical outcome related to epidural fibrosis.
