Purpose: Restless Legs Syndrome (RLS) is a motor and neurological disorder that is associated with a sense of urgency to move the legs. It is necessary to use
non-pharmacological treatments to reduce the symptoms of this syndrome.

Methods: The present study is a two-group clinical trial, in which transcutaneous electrical nerve stimulation (TENS) intervention was performed on 20
patients (10 patients in each group) for 3 sessions in 3 consecutive days. The aim of this research was to evaluate the effect of TENS on RLS in patients with
this complaint referring to a private medical center.

Results: The mean age of participants was 46.56 ± 9.16 years. There was a significant difference in RLS levels before and after the final intervention in
each group. There was no significant difference of RLS rate between the two groups after final intervention.

Conclusion: If future studies with a larger sample size confirm the results of the present study, patients can use a portable TENS according to the advice of
a physician at home to reduce nocturnal symptoms associated with RLS syndrome.

Introduction: Foramen magnum meningiomas corresponds about 3 to 3.2% of all meningiomas. And 60 to 77% of all benign extramedullary tumors of the craniocervical junction. Due to its depth, these lesions and the delicate anatomical relationships, their resection demands detailed mastery and control of the complex anatomy of the region.Different approaches for resection of these lesions have been reported:suboccipital,transcondylar, transoral and retrosigmoid craniotomy.

Far lateral transcondylar approach have proved to be a safe, wide, sterile surgical access for the exposition of the ventral space to the central nervous system that allows good manipulation in a parallel plane. There are specific considerations according to the position and encasement of the vertebral artery, and the extension of the bone resection.

With the development of three-dimensional (3D) printing technology, more applications have been used in clinical settings for the planning and performance of surgical procedures, and neurosurgery is not the exception. 3D printed models are created through layer-by-layer deposition by high-precision 3D printers using reconstructed patient CT-scan images.

Materials and methods: The clinical case of a patient with a diagnosis of foramen magnum meningioma, pre-surgical planning with a 3D model, surgical resolution, and literature review are presented.

Results: Pre-surgical planning is performed on a 3D model, the patient undergoes surgical resolution without complications and she is discharged from the service due to improvement.

Conclusion: The use of current tools allows adequate and precise planning of neurosurgery procedures, as well as extensive explanation and taking individual anatomical considerations to reduce the risk of complications during surgery. 3D models represent a valuable surgical educational tool that improves the understanding of complex lesions of the skull base, for the neurosurgical residents
