atypical connections in the formation of the brachial plexus are prevalent and have been reported in different articles. the present report describes a case of variation of the median nerve observed in the iranian male cadaver during routine trial dissection. there are three roots for median nerve. median nerve is formed by joining two lateral and medial cords of brachial plexus. third root of ...

abstract   background : although, different studies on end-to-side nerve repair, results are controversial. the importance of this method in case is unavailability of proximal nerve. in this method, donor nerves also remain intact and without injury. in compare to other classic procedures, end-to-side repair is not much time consuming and needs less dissection. overall, the previous studies in ...

Introduction: Repair of peripheral nerve injuries is an intensive area of challenge and research in modern reconstructive microsurgery. Intensive research is being carried out to develop effective alternatives to the standard nerve autografting, avoiding its drawbacks. The aim of the study was to evaluate the effectiveness of a newly designed mechanical device for the reconstruction of the...

Objective(s): To investigate the systemic and local immune status of two surgical rat models of sciatic nerve injury, a crushed sciatic nerve, and a sciatic nerve transection Materials and Methods:Twenty-four adult male Sprague-Dawley rats were randomly divided into three groups: sham-operation (control group), sciatic nerve crush, and sciatic nerve transaction. Sciatic nerve surgery was perfor...

Leprosy is a chronic infectious disease endemic in Iran that mainly involves skin and peripheral nerves. Leprosy has several clinical forms. One of them is “Pure neural leprosy”. The diagnosis of this form is delayed due to lack of clinical signs in other tissues and can lead to permanent deformity. I will discuss my experience for 20 years in the diagnosis and treatment of this form of leprosy...

Objective(s):  The aim of this study was to evaluate the final outcome of nerve regeneration across the eggsell membrane (ESM) tube conduit in comparison with autograft. Materials and Methods: Thirty adult male rats (250-300 g) were randomized into (1) ESM conduit, (2) autograft, and (3) sham surgery groups. The eggs submerged in 5% acetic acid. The decalcifying membranes were cut into four pie...

Background: Peripheral nerves may be damaged during an injury and its current standard treatment is using an autologous nerve. Objectives: The purpose of this experimental study is to evaluate and compare the histological results of nerve regeneration after using the eggshell membrane (ESM) guidance channel with autograft. Materials and Methods: Thirty adult male rats were divided into th...

A 14-year-old who had 7episodes of relapsing unita­leral paralysis of facial nerve during 7 year-;. was admit­ted to the hospital. The X-Ray revealed Osteopetrosis, and the bone biopsy was proved this diagnosis. But there was not any bone fracture, or anemia. Pressure over fa­cial nerve caused by condensation of entire facial nerve canal. was detected by tomographia. Probablv intermitant facial...
