Cranial nerve palsy is a rare but recognised complication of epidural anaesthesia, most commonly presenting as diplopia secondary to abducens nerve palsy. While upper cranial nerve palsies have been documented on numerous occasions, lower cranial nerve palsies, including recurrent laryngeal nerve palsy, are exceedingly rare. This case describes a 37-year-old female who, following epidural anaesthesia for spontaneous vaginal delivery of her first child, presented with dysphonia. Read More

Surgical treatment of petrous apex chondrosarcoma is challenging due to the location of the tumor. Using an endoscopic technique for tumor resection is favored since it provides a minimally invasive approach. A 57 years old female was admitted for acute onset of left abducens nerve palsy and occasional headache mainly on the left side of the retro-orbital area with some radiation to the left occiput.

We present the case of a 34-year-old woman, who presented to our department with a 4 months history of dizziness, hearing loss, and tinnitus on the right side. MRI (magnetic resonance imaging) scan demonstrated a large extra-axial lesion, suggestive of a meningioma, with dural attachments to the petrosal bone surface and tentorium, closely related with the trigeminal, abducens, facial, vestibulocochlear, and lower cranial nerves in the right side. Treatment options were discussed with the patient, and surgical resection was selected to remove the lesion, and decompress the cranial nerves and brainstem. Read More

Background: Skull-base metastases frequently cause progressive ipsilateral disturbances of cranial nerves or pain, resulting in poor quality of life in patients with cancer. Magnetic resonance(MR)imaging is the method to detect skull-base metastases, which demonstrates focal lesions of low-intensity signal and enhancement on T1-weighted MR images.
Methods: We reviewed clinical data and MR images from 127 patients with skull-base metastases diagnosed at Shizuoka Cancer Center Hospital between August 2012 and November 2017. Read More

Background: Recently, the superior rectus transposition has been widely adopted for the treatment of complete abducens palsy and Duane syndrome. This procedure is useful in that there is a decreased risk of anterior segment ischemia compared to complete vertical rectus transposition, possibly decreased incidence of postoperative-induced vertical deviations than complete vertical rectus transposition, and improvement in abduction compared to simple medial rectus recession. One difficulty with this procedure is the lack of adjustability in most patients. Read More

Burkitt lymphoma is a late complication of HIV, and bilateral cranial nerve palsies are extremely rare in patients with AIDS. A twenty year old Caucasian male with known congenital HIV who had been non-adherent with anti-retroviral therapy presented with multiple cranial nerve palsies and was eventually diagnosed with Burkitt lymphoma. Before chemotherapy, he was started on radiation therapy to the brain, meninges, and base of skull with the intent of improving cranial nerve palsies and preventing further neurological sequelae since the cranial nerve palsies were dense and there was concern that intrathecal chemotherapy would have less penetration than radiation.

Purpose: Although widely practiced, surgical treatment of strabismus has varying levels of success and permanence. In this study we investigated adaptive responses within the brain and the extraocular muscles (EOM) that occur following surgery and therefore determine long-term success of the treatment.
Methods: Single cell responses were collected from cells in the oculomotor and abducens nuclei before and after two monkeys (M1, M2) with exotropia (divergent strabismus) underwent a strabismus correction surgery that involved weakening of the lateral rectus (LR) and strengthening of the medial rectus (MR) muscle of one eye.

Intraoperative monitoring systems that utilize various evoked potentials for the detection and/or preservation of cranial nerves have become increasingly common due to recent technical and commercial developments, particularly during skull base surgeries. We established a novel system for the intraoperative monitoring of the extraocular motor nerves (eOMNs) using a piezoelectric device capable of detecting imperceptible vibrations induced by ocular movement, with sensors placed on the eyelids alone. We first evaluated the efficacy and reliability of this device for the intraoperative monitoring of eOMNs in two Beagle dogs. Read More

Background: Ocular neuromyotonia (ONM) is characterized by episodic diplopia, which is usually triggered by prolonged eccentric gaze of the affected extraocular muscles. The spell is characterized by involuntary, occasionally painful, sustained contraction of one or more extraocular muscles innervated by the oculomotor, trochlear, or abducens nerve. ONM usually occurs as a late consequence of radiotherapy around the parasellar area, although idiopathic cases have been reported. Read More

Vascular endothelial growth factor (VEGF) was initially characterized by its activity on the vascular system. However, there is growing evidence indicating that VEGF also acts as a neuroprotective factor, and that its administration to neurons suffering from trauma or disease is able to rescue them from cell death. We questioned whether VEGF could also maintain damaged neurons in a neurotransmissive mode by evaluating the synthesis of their neurotransmitter, and whether its action would be direct or through its well-known angiogenic activity.
