Summary: The study aims to assess the ability of preoperative MRI tractography to visualize and predict the facial nerve path in relation to an intra-parotid mass. The results showed a high visualization rate of the facial nerve trunk and its divisional branches, with good agreement with intraoperative descriptions. This suggests that fiber tractography analysis by MRI could be a valuable tool in guiding surgical procedures involving parotid masses.

Summary: This study introduced a novel cortical mapping method based on three categories of nerve fibers: projection, commissural, and association fibers. Analysis of MRI data revealed that the majority of nerve fibers in the brain are association fibers, with specific regions showing distinct distributions of projection and commissural fibers. Hemispheric asymmetries in fiber density were also observed in certain brain areas.

Summary: Perineural spread of breast cancer to the brachial plexus is a rare but often misdiagnosed complication, characterized by pain, sensory alterations, and upper extremity weakness. This study retrospectively analyzed the clinical, radiological, and pathological data of 19 patients with biopsy-proven perineural spread of breast cancer to the brachial plexus.

Summary: Novel imaging techniques have been developed for precise delineation of thalamic nuclei, allowing for reliable identification of up to 13 distinct nuclei bilaterally. These high-resolution imaging methods have potential implications for studying thalamic connectivity, basic research, and presurgical planning.

Summary: Neurolymphomatosis (NL) is a rare manifestation of lymphoma that affects the peripheral nervous system. This study investigates the progression of extraspinal NL to the cauda equina and its implications for diagnosis. The authors found that perineural spread plays a crucial role in infiltrating the cauda equina and propose a phasic mechanism for this spread. MRI and FDG PET/CT are useful diagnostic tools for NL. Recognizing this mechanism can lead to safer biopsy targets and better functional recovery.

Summary: This observational study found that intraoperative facial nerve dissection during parotidectomy can lead to decreases in electromyography (EMG) signals in facial muscles, with most patients experiencing complete recovery of facial functions within 6 months. Signals with >50% amplitude decreases were associated with regional facial dysfunction.

Summary: Facial nerve monitoring during parotid gland surgery remains a debated topic among Otolaryngologist-Head and Neck Surgeons. A meta-analysis of 10 studies showed that the use of intraoperative facial nerve monitoring may decrease the risk of immediate and permanent postoperative facial nerve weakness, but more prospective randomized trials are needed to confirm these findings.

Summary: This study examined patients with perineural spread of cutaneous squamous cell carcinoma of the head and neck. The results showed that most patients had recurrent disease (89.0%) and simultaneous trigeminal nerve involvement (67.1%). Surgery and post-operative radiotherapy were the main treatments, and early-stage disease and clear surgical margins improved outcomes.

Summary: A method for predicting postoperative facial nerve paralysis (POFNP) using intraoperative nerve monitoring (IONM) during parotid surgery was investigated. The prediction was assessed by comparing the amplitude response ratio (ARR) between stimulation in the facial nerve trunk and each branch using facial nerve monitoring. It was found that when the ARR cutoff value was set at 0.55, the sensitivity, specificity, and accuracy of POFNP diagnosis by ARR were 96.5%, 93.1%, and 96.8%, respectively.

Summary: This study found that 27.3% of patients with superior semicircular canal dehiscence syndrome had endolymphatic hydrops detected by MRI. There was a significant correlation between the presence of endolymphatic hydrops on MRI and sensorineural hearing loss.

Summary: This study retrospectively analyzed 128 patients with benign recurrent vestibulopathy since 2010. Among these patients, 23% showed endolymphatic hydrops on MRI, with the lateral semicircular canal being the most commonly affected location. The most frequently impaired vestibular tests were the caloric test and the skull vibration-induced nystagmus test.

Summary: The study aims to describe the MRI characteristics of intralabyrinthine schwannoma (ILS) on post-contrast 4h-3D-FLAIR images. Through a retrospective multi-center analysis, it was found that ILS appeared as a hypointense filling defect on 4h-3D-FLAIR images, accompanied by diffuse perilymphatic hyperintensity.

Summary: This study aimed to shorten the delay between gadolinium administration and MRI acquisition for hydrops evaluation using an optimized 3D-FLAIR sequence in Meniere's disease patients. The results showed that the signal intensity ratio at 2 h was not significantly inferior to that at 4 h, and the volume equivalence of endolymphatic structures was also proven between 2 and 4 h. The optimized sequence provided reliable diagnosis of endolymphatic hydrops and blood-labyrinthine-barrier impairment.
