introduction: to report our experience with a large series of surgical procedures for removal of cerebellopontine angle (cpa) tumors using different approaches.   materials and methods: this was a retrospective analysis of 50 patients (mean age, 49 years) with cpa tumors (predominantly acoustic neuroma) who underwent surgical removal using appropriate techniques (principally a translabyrinthine...

When acoustic neuromas are found in younger age groups, they are typically bilateral and associated with neurofibromatosis (NF). A unilateral acoustic neuroma in a child or adolescent without NF is rare. We report audiometric, auditory brainstem response (ABR) and magnetic resonance imaging (MRI) data for a 15-year-old male with an acoustic neuroma but without associated NF. The patient was see...

Intracellular recording and extracellular field potential (FP) recordings were obtained from spinal cord dorsal horn neurons (laminae I-IV) in a rat transverse slice preparation with attached dorsal roots. To study changes in synaptic inputs after neuroma formation, the sciatic nerve was sectioned and ligated 3 weeks before in vitro electrophysiological analysis. Horseradish peroxidase labeling...

BACKGROUND The forelimb amputee poses many reconstructive challenges in the clinical setting, and there is a paucity of established surgical models for study. To further elucidate the pathogenic process in amputation neuroma formation, we created a reproducible, well-tolerated rabbit forelimb amputation model. METHODS Upon approval from the Institutional Animal Care and Use Committee, 5 New Z...

BACKGROUND As a parameter for the evaluation of the vestibular evoked myogenic potential (VEMP), amplitude has been used clinically. However, the significance of latency has not been considered. OBJECTIVE To clarify the diagnostic value of latencies of the VEMP. DESIGN We reviewed records of the VEMP of patients with various diseases and compared them with records of healthy volunteers. S...

The medium and long-term effects of electrophysiologic monitoring on the facial nerve function in minimally invasive surgery treating acoustic neuroma were studied. Sixty-two patients with acoustic neuroma taking minimally invasive surgeries in Dezhou Hospital from August 2014 to September 2015 were selected and randomly divided into 29 cases of the control group and 33 cases of the observation...

We investigated 29 cases, diagnosed clinically as having Morton's neuroma, who had undergone MRI and ultrasound before a neurectomy. The accuracy with which pre-operative clinical assessment, ultrasound and MRI had correctly diagnosed the presence of a neuroma were compared with one another based on the histology and the clinical outcome. Clinical assessment was the most sensitive and specific ...

INTRODUCTION Peripheral nerve disruptions, frequently occurring during limb injuries, give rise to serious complications of patients recovery resulting from limitations in neural tissue regeneration capabilities. To overcome this problem bridging techniques utilizing guidance channels gain their importance. Biodegradable polymeric tubes seem to be more prospective then non-degradable materials ...

Following nerve injury or transection, a disorganized sprouting of axons can result in painful neuroma formation due to disruptions and damage the peripheral tissue. Currently, there are various treatments; however, nonsurgical treatment is inconsistent high rate residual pain postoperatively. This study reports results from pilot phase multicenter clinical on use Axoguard Nerve Cap® (nerve cap...
