Purpose: The purpose of this study was to evaluate the effects of epineurotomy on the post-surgical median nerve volume and clinical outcomes in carpal tunnel syndrome (CTS) patients with a prominent nerve narrowing.
Methods: This was a prospective, randomised, double-blind controlled trial. Patients (n = 50) were randomised (1:1) to open-field surgical carpal tunnel release followed by a longitudinal epineurotomy of the nerve (test), or to open-field release without epineurotomy (control).
Results: The nerve volume was slightly larger in the test group 90 days post-surgery (by 10.5 %, p = 0.157) but not 180 days post-surgery. No relevant electropyhsiological or clinical difference between groups and no effect of the nerve volume was observed. The subjective pain reduction was slightly more prominent in the control group at 180 days. Larger post-surgical nerve volume was associated with lower pain, but only in the control group.
Conclusions: Even in selected CTS patients, longitudinal epineurotomy confers no benefit regarding the nerve volume or clinical outcomes over a simple carpal tunnel release.

Objective: Skull base chordomas (SBCs) often present with cranial nerve (CN) VI deficits. Studies have not assessed the prognosis and predictive factors for CN VI recovery among patients presenting with CN VI deficits.
Methods: The medical records of patients who underwent resection for primary chordoma from 2001 to 2020 were reviewed.
Effectiveness of Low-Volume Versus High-Volume Ropivacaine for Ultrasound-Guided Maxillary Nerve Block in Double-Jaw Surgery: A Randomized Non-inferiority Trial.

Background: Ultrasound-guided maxillary nerve block (UGMNB) is applied in oral and maxillofacial surgery to improve perioperative analgesia, decrease the risk of postoperative nausea and vomiting, and enhance recovery. However, the optimum volume of ropivacaine used for UGMNB is undetermined. Thus, it was hypothesized that in patients undergoing double-jaw surgery, low- and high-volume ropivacaine reduces perioperative pain with similar efficacy.

Objective: This study aims to evaluate the clinical significance of ultrasound-based measurement of optic nerve sheath diameter (ONSD) in predicting intracerebral hemorrhage (ICH) complicated by cerebral-cardiac syndrome (CCS).
Methods: Patients with ICH and who were treated in the intensive care unit (ICU) at Shijiazhuang People's Hospital between October 2021 and November 2022 were included in this study. Participants were divided into two groups: those with CCS and those without.

Background: Intracranial hemorrhage (ICH) is a devastating stroke subtype with a high rate of mortality and disability. Therapeutic options available are primarily limited to supportive care and blood pressure control, whereas the surgical approach remains controversial. In this study, we explored the effects of noninvasive vagus nerve stimulation (nVNS) on hematoma volume and outcome in a rat model of collagenase-induced ICH.
