| Abstract | INTRODUCTION: Surgery of intradural extramedullary spinal cord tumors (IESCT) carries the risk of new neurological deficits in the post-operative period. Intraoperative neurophysiological monitoring (IONM) represents the most effective technique able to improve clinical and functional outcomes, which are obtained through identification and real-time intraoperative monitoring of spinal cord, giving informations about neurological conduction of both, spinal cord long pathways and cauda equina radices. The most widely used and reliable techniques are somatosensory evoked potentials (SEPs), motor evoked potentials (MEPs) and D-wave registration. Although in the literature there are recent evidences of the IONM usefulness, there are not uniform opinions about the different techniques employed, and, their use in IESCT. In the present study we describe the results in our 2-year experience at the Neurosurgery of the University of Messina Hospital. MATERIALS AND METHODS: Our protocol includes evaluation of SEPs from posterior tibial nerve stimulation, MEPs obtained with elevate voltage electrical transcranial stimulation (through multiple myomeric registration of motor evoked responses from inferior limbs), D-Wave registration (through epi- and intradural registration after single pulse electrical transcranial stimulation) in spinal tumor surgery. RESULTS: We did not recorded any intraoperative complication by the use of our IONM protocol. In all patients IONM was useful for correct neurological and functional identification of spinal cord. We observed an optimal correlation between neurological examination on admission and responses from IONM of inferior limbs SEPs and MEPs. In fifty percent of patients, the D-wave registration was the most useful intraoperative tool, due to the lack of motor and somatosensory evoked responses. We matched all pre and post-operative neurological and neurophysiological data, along with tumors' features (localization, dimensions and histology) in order to quantify the impact of IONM on outcome. In our series, none of the patients presented with neurological worsening in the post-operative period. Conversely, surgical treatment of IESCT lead to a significant improvement of neurological status of our patients. CONCLUSIONS: Our preliminary data, although based on a limited series of patients evaluated at a single institution, confirm the role of IONM as an essential tool in operative work-up of all spine surgeries, including IESCT, to achieve an optimal post-operative functional outcome. This study gives further evidences about relevance, impact and usefulness of IONM in IESCT surgery. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
