Besides walking ability, spasticity also severely affects functional mobility in general, self-care, and quality of life. The majority of MMC patients experience neurogenic bladder. Treatment of spasticity can be symptomatic or target its cause. Medical and surgical options are available for both limb and bladder spasticity. Regular physiotherapy and orthotics are used to prevent contractures and the early introduction of orthoses is the cornerstone of a gait training program.

While most arachnoid cysts in typical middle or posterior cranial fossa locations are seldom symptomatic, suprasellar cysts may become symptomatic due to the potential for ventricular outflow obstruction and hydrocephalus. Typical standard of care for the treatment of these lesions is endoscopic fenestration with third ventriculostomy, or the placement of ventriculoperitoneal or cystoperitoneal shunts. The surgical and anaesthetic risks of traditional interventions may be higher in the early neonatal period, including leak of cerebrospinal fluid, infection, and premature failure of ventriculostomy or shunts. This note describes a novel bedside ultrasound-guided technique to percutaneously fenestrate large suprasellar arachnoid cysts under local anaesthesia. The technique involves insertion of a 25-g spinal needle until contact with the membrane of the arachnoid cyst medially, followed by a lateral sweeping to widely incise/fenestrate the lesion into the ventricular space under continuous ultrasound visualisation.
