Objectives: False-negative or false-positive responses in intraoperative neuromonitoring (IONM) using electromyography (EMG) in thyroid surgery pose a challenge. Therefore, we developed a novel IONM system that uses a surface pressure sensor instead of EMG to detect muscle twitching. This study aimed to investigate the feasibility and safety of a new IONM system using a piezo-electric surface pressure sensor in an experimental animal model. Methods: We developed the surface pressure sensor by modifying a commercial piezo-electric sensor...

We evaluate the role of intraoperative neuromonitoring (IONM) in thyroidectomy performed for Graves' disease (GD) with an emphasis on recurrent laryngeal nerve (RLN) management and completeness of resection. The study is a retrospective series comprising 55 thyroidectomy (control group) versus 82 procedures with intermittent IONM (I-IONM) and 72 by means of continuous IONM (C-IONM). In the control group the laryngeal nerves have been identified by visualization solely. In the I-IONM group both vagal nerve (VN) and RLN have been localized and monitored during thyroid resection...

Arthroscopic hip surgery is performed routinely for the treatment of various hip disorders. Leg traction during labral tear repair, femoroplasty, and acetabuloplasty for hip stabilization can stretch the peripheral nerves. This may cause temporary or permanent nerve injury. This study illustrates the benefit of utilizing multimodality Intraoperative Neurophysiological Monitoring (IONM) during hip surgical procedures. We performed a retrospective review of 10 arthroscopic hip surgeries with neurophysiological monitoring at one medical center...

Recurrent laryngeal nerve (RLN) palsy can result in motility disorders of the vocal cord muscles and/or fatal respiratory complications. Procedures aimed at checking for intraoperative RLN injuries have not been established. Intraoperative nerve monitoring( IONM) informs electromyographic activity of the vocal cord muscles to a surgeon by visual and aural signals. In this chapter, we introduce methods for using IONM during esophageal cancer surgery. Since we introduced IONM, several cases in which surgeons have had difficulty visually identifying the RLN have been reported...

BACKGROUND: Intraoperative neural monitoring (IONM) has gained widespread acceptance as an adjunct to the gold standard of visual identification of the recurrent laryngeal nerve (RLN) during thyroid surgery. Currently, laryngeal electromyography (EMG) recording during IONM is almost always performed using endotracheal tube (ETT) surface electrodes placed adjacent to vocal folds originating from the inner surface of the thyroid cartilage (TC). Therefore, it was hypothesized that surface recording electrodes placed on the outer surface of the TC should enable access to the EMG response of the vocal folds during IONM...

OBJECTIVES: Well-designed longitudinal studies assessing effectiveness of intraoperative neurophysiologic monitoring (IONM) are lacking. We investigate IONM effects on cost and administrative markers for health outcomes in the year after cervical spine surgery. METHODS: We identified single-level cervical spine surgeries in commercial claims. We constructed linear regression models estimating the effect of IONM (controlling for patient demographics, pre-operative health, services during index admission) on total spending, neurological complications, readmissions, and outpatient opiate usage in the year following index surgery...

OBJECTIVE: Because the anatomical structure of the brachial plexus is very complex, surgical treatment of tumors in this region is challenging. Therefore, a lot of clinical and surgical experience is required for successful treatment; however, many neurosurgeons have difficulty accumulating this experience owing to the rarity of brachial plexus tumors. The purpose of this report is to share our surgical experience with brachial plexus tumor with other neurosurgeons. METHODS: The records of 18 consecutive patients with brachial plexus tumors who underwent surgical treatment between January 2010 and December 2017 in a single institution were retrospectively reviewed...
