Sciatic nerve is the thickest nerve of the sacral plexus, which innervates many muscles and vast areas of the skin of the lower limb. It leaves the pelvis via the greater sciatic foramen, emerges into the gluteal region by passing under the piriformis muscle, and descends beneath the gluteus maximus to divide into its terminal branches: tibial and common peroneal nerve at the superior angle of ...

Background & Aims: Surgeons are not willing to participate in thyroid surgeries due to dangerous, although rare, complications of the procedure. Post thyroidectomy complications are divided in early and late onset; hypocalcemia, bleeding, thyroid storm and recurrent laryngeal nerve (RLN) injury are the most important ones. This study was performed to compare the frequency of recurrent laryngeal...

Background and Importance: Our learning curve during two decades of neurosurgical practice has been changed from an abstractive to a more meaningful and conductive state. In cases of fifth nerve neurinoma, pre-operative anatomopathologic diagnosis could lead us to a pre-planned program during and after the surgery to get the safe surgical result. Case Presentation: Representation of two comp...

Objective-To evaluate effect of chitosan conduit for peripheral nerve regeneration using sciatic nerve transection model in rat Design- Experimental in vivo study. Animals- Sixty healthy male Wistar rats. Procedures-The rats were divided into four experimental groups (n=15) randomly. In sham group the left sciatic nerve was exposed through a gluteal muscle incision and after careful...

one of the important causes of strabismus in all ages is extraocular muscles paralysis due to 3rd, 4th and 6th cerebral nerve palsies. exact and on-time treatment can result in improvement of deviation, am-blyopia and abnormal head posture. we studied epidemiological characteristics of extraocular muscles paralysis. this retrospective study performed on 131 subjects (58% male). records of patie...

regarding the importance of sciatic nerve distribution in replacement of anal sphincter and sciatic nerve block we decided to study this matter for the first time in iran. in this way 100 cadavers (88% male and 12% female) were dissected and studied by loop microscope. the results shows that primarily, according to the first branch derived from sciatic; there would be 4 main groups. if this sam...

background :there is not any data available about the effect of high bar pressure condition on intracranial pressure. in this study, the effect of diving on the optic nerve and sheath diameters as non-invasive markers of intracranial pressure has been investigated.   methods : twenty professional male divers from twenty one volunteers were chosen for this cross-sectional study. only one person ...

introduction: malignant tumors of the parotid gland account scarcely for 5% of all head and neck tumors. most of these neoplasms have a high tendency for recurrence, local infiltration, perineural extension, and metastasis. although uncommon, these malignant tumors require complex surgical treatment sometimes involving a total parotidectomy including a complete facial nerve resection. severe fu...

Carpal tunnel syndrome (CTS) is the most well-known and frequent form of median nerve entrapment, and accounts for 90% of all entrapment neuropathies. Entrapment neuropathies of the ulnar nerve are relatively common with ulnar neuropathy at the elbow more prevalent than ulnar neuropathy at the wrist. The diagnosis of ulnar neuropathy at the elbow is usually confirmed in a relatively straight – ...

Background: Axotomy causes sensory neuronal loss. Reconnection of proximal and distal nerve ends by surgical repair improves neuronal survival. It is important to know the morphology of primary sensory neurons after the surgical repair of their peripheral processes. Methods: Animals (male Wistar rats) were exposed to models of sciatic nerve transection, direct epineurial suture repair of sciati...
