Case Reports
Successful treatment of refractory status epilepticus using anterior thalamic nuclei deep brain stimulation.
Refractory status epilepticus (RSE) is considered a medical emergency in neurology and is related to high mortality. We report a successfully treated case of RSE using deep brain stimulation (DBS) at the anterior thalamic nuclei (ATN) in a 17-year-old woman. ⋯ DBS at the ATN significantly improved both the electroencephalography and clinical presentation in the patient with RSE. DBS at the ATN should be considered as a possible treatment choice once a patient develops RSE.

Identification and protection of the cochlea during anterior petrosectomy is key to prevent hearing loss. Currently, there is no optimal method to infer the position of the cochlea in relation to the Kawase quadrangle; therefore, damage to the cochlea during anterior petrosectomy remains a substantial risk. ⋯ The cochlear safety line is a reliable landmark to avoid the cochlea during the Kawase approach. When expanding the anterior petrosectomy posteriorly, the cochlear safety line can be used as a reliable landmark to prevent exposure of the cochlea, thus preventing hearing loss.

Selective tibial neurotomy (STN) was considered as an effective procedure for the treatment of spastic feet. It is also widely used for treating obese calves in some Asian countries. This study aimed to provide morphologic measurement data and theoretical support for the operation and intraoperative localization. ⋯ The calf circumference was positively related to the thickness of the soleus and the gastrocnemius. Diverging patterns of tibial nerve branches were multiple, and caution should be used to prevent damaging other branches. Tibial nerve, branches, and diverging sites could be seen clearly in the ultrasonic image. A preoperational ultrasonic examination is recommended.

Approximately 95% of tumors occurring within the internal auditory canal (IAC) are vestibular schwannomas. Many undergo stereotactic radiation without definitive tissue diagnosis. Rare IAC tumors are not all radiosensitive and are poorly described. ⋯ Clinical examination and imaging alone were insufficient to correctly identify these tumors. Definitive pathologicdiagnosis should be strongly considered to help tailor treatment.

We describe our single-center experience treating unruptured brain arteriovenous malformations (uBAVMs) with microsurgical treatment. ⋯ Good functional outcome can be achieved by microsurgical resection in S-M grade I and II and selected grade III uBAVMs. Surgical resection for high-grade (grade IV and V) uBAVMs is challenging. A high seizure-free rate can be achieved in patients with initial seizure presentation.
