background: the most common neoplasm of the salivary glands is pleomorphic adenoma and the most common complications of its surgical removal are facial nerve dysfunction (temporary or permanent) and auriculotemporal syndrome (frey’s syndrome). one of the surgical techniques in pleomorphic adenoma is partial parotidectomy. the whole excised tumor is surrounded by a safety margin of parotid tissu...

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 ...

PURPOSE To determine the effect of upper eyelid platinum chain implantation, with the pretarsal fixation technique, on corneal astigmatism. METHODS This is a prospective, cohort study. Fifteen eyes of 15 patients underwent upper eyelid platinum chain implantation, with the pretarsal fixation technique, for facial nerve palsy. Information recorded included patient demographics, etiology for fa...

Neuropathic pain may arise following peripheral nerve injury though the molecular mechanisms associated with this are unclear. We used proteomic profiling to examine changes in protein expression associated with the formation of hyper-excitable neuromas derived from rodent saphenous nerves. A two-dimensional difference gel electrophoresis (2D-DIGE) profiling strategy was employed to examine pro...

Nerve injury frequently triggers hyperexcitability and the ectopic initiation of impulses in primary afferent axons. An important consequence is neuropathic paresthesias and pain. Electrogenesis in normal afferents depends on appropriate Na+ channel concentrations. Therefore, we have asked whether injury might trigger changes in axolemmal Na+ channel distribution that could account for neuropat...

OBJECTIVE Traumatic amputation at the pelvic level is a rare procedure with few studies addressing long-term complications. Painful neuroma formation may form at the site of nerve transection and cause significant impairments in daily living. Ultrasound-guided cryoablation therapy has grown in popularity and should be considered in patients with painful neuromas. This is a case report of comple...

Peripheral neuropathy is defined as deranged function and structure of peripheral, motor, sensory, and autonomic neurons, involving either the entire neuron or selected levels. The major categories of peripheral neuropathies are seen in Table 28-1. Because this chapter is concerned with nerve problems seen in the foot that are most amenable to local treatment, only the last four categories are ...

For many patients, pain is the first sign of cancer and, while pain can be present at any time, the frequency and intensity of pain tend to increase with advancing stages of the disease. Thus, between 75 and 90% of patients with metastatic or advanced-stage cancer will experience significant cancer-induced pain. One major unanswered question is why cancer pain increases and frequently becomes m...

A 74-year-old female suffered hearing disturbance in the right ear persisting for several years, followed by sudden onset of right facial nerve palsy. Her symptoms gradually worsened and neuroradiological imaging revealed a 4-cm cerebellopontine angle (CPA) tumor. Intraoperatively, the tumor was found to originate from the facial nerve. Total removal of the tumor was achieved, followed by a spl...
