Bilateral laminotomy allows adequate and safe decompression of the spinal canal in patients with lumbar stenosis; this technique ensures a significant improvement in patients' symptoms, disability, and quality of life. Neurological outcome after bilateral laminotomy and laminectomy is similar, but a lower incidence of complications and iatrogenic instability has been shown in the medium and long term for patients who undergo bilateral laminotomy.
