The Utility of High-Definition 2-Dimensional Stereotactic Exoscope in Cranial and Spinal Procedures.
The use of an exoscope in neurosurgical procedures has been proposed to improve ergonomics and to overcome the limitations faced with the microscope and endoscope. However, there remains scarcity of data regarding its surgical utility and outcomes. The authors report their experience and evaluate the surgical outcomes using a high-definition 2-dimensional (HD-2D) stereotactic exoscope in the management of various cranial and spinal pathologies. ⋯ The HD-2D stereotactic exoscope offers a wider field of view, greater mean focal distance, enhanced ergonomics, and immersive stereotactic visual experience. The lack of stereopsis remains the principal limitation of its use, and further optimization of surgical outcomes might be achieved with newer 3-dimensional models.

Trigeminal neuralgia (TN) is a common pain syndrome of the nervous system,. Although about 90% patients who were refractory to medications could be free from pain after microvascular decompression (MVD), some patients did experience recurrence. The study aimed to analyze clinical characteristics of patients with recurrent TN, recurrence factors of TN, and prognosis after re-do MVD. ⋯ Teflon granuloma was the most common cause of TN recurrence in current study, new NVC was also saw in some patients. Patients with recurrent TN could get satisfactory results from re-do MVD.

We sought to introduce technical notes of full endoscopic lumbar interbody fusion (FE-LIF) with an anterior expandable cylindrical fusion cage. ⋯ FE-LIF is a safe and effective minimally invasive lumbar surgery with an anterior expandable cylindrical fusion cage.

Posterior interosseous nerve palsy (PINP) is a disorder caused by damage to the posterior interosseous nerve, resulting in weak extension of the wrist and fingers as well as radial deviation of the wrist. ⋯ The window test introduces a reference frame making it easier to assess wrist radial deviation and offering a simple evaluation that can be administered by virtually anyone. These findings indicate that the implementation of the window test will increase the accuracy and effectiveness of PINP diagnosis, thus allowing early diagnosis and better management.
