Our findings suggest that nerve transfer of collateral branches, where possible, (such as in cases with upper or extended upper brachial plexus palsy) might be a method of choice, offering better results and quality of recovery.
After the injury of facial nerve, facial muscles are subjected to complex series of biochemical and histological changes, which lead to muscular atrophy if reinnervation is not restored. Facial palsy is very difficult to manage completely. Regardless this fact, the plan of correction has to be directed towards the following: restoration of normal function, normal facial appearance at rest, symmetry in voluntary movements as well as symmetry in involuntary and emotional movements. Static suspension methods were used in our study. All patients had unilateral complete facial nerve palsy but one female patient who experienced the palsy of frontal branch of n.facialis. This method was successfully used to lift the eyebrow, the lid and to improve lagophthalmus on the paralytic side, then the angle and paralytic part of the lip, to reinforce buccal wall of oral cavity as well as to reconstruct new nasolabial fold. The results were satisfactory and permanent.
The aim of this work is to show the highlights of electrophysiological diagnostics, i.e. its potentials in level diagnostics of traumatic disfunction of brachial plexus (BP). In that manner we have analyzed the results of electrophysiological research, made on 53 patients with different levels and grades of traumatic lesion of brachial plexus. We have also analyzed the authors' opinions and points of view who have contributed in solving these problems. Brachial plexus is a complex, vulnerable nerve structure that is often, in life, exposed to direct or indirect influence of mechanical force. Preserved integrity of bone structures of a shoulder protects BP from longitudinal forces, which are the most common causes of injury of this structure. Traction mechanism of the injury is always up to date in the cases of fractures and dislocation of the skeleton in this region. In the early childhood, mechanical injuries of brachial plexus are caused by distocia in the second delivery period, while in adulthood most common injuries are caused by sudden and intensive forces, which cause disfunction of plexus by traction mechanism (dislocation of a shoulder and clavicular fracture) and by direct action (stabing and piercing injuries). Slowly progressive, expansive, degenerative and inflammatory processes of neighbouring organs are causing the disfunction of the plexus as well. Traction actions are aimed mostly at radiculars as a vulnerable structure that is placed between relatively mobile shoulder joint and rigid cervical part of vertebral column. Complex anatomical structure and mutual overlapping of radicular motor and sensitive innervation of muscles and dermatoms, make the diagnostics of disfunction of this periphery nerve structure very difficult and complicated. Disfunction of neighboring bone, vascular and muscle elements as well as the nearness of vital organs, which complicates even more the diagnostics. Taking into account the general analysis of all electrophysiological results of the research on 53 patients with an PB injury, we have concluded that none of the functional methods is not sovereign, i.e. the contribution of this research is complementary also with roentgenological results. Clinical data are unavoidable, but they are not enough without good argumentation, especially for the level of lesion, pre- or postganglionary. Electromiography gives reliable results for the phase and the grade of denervation of particular muscle groups, and that way it is possible to conclude, indirectly, which part of the plexus is in disfunction. Special attention should be paid to EMG of paraspinal muscles, where the signs of denervation are aleays indicating intradural lesion of the radicular. In the examined group, 52% of the patients with radicular disfunction had the signs of denervation in paraspinal muscles. Examination of the sensitive action potentials is another method by which we can see the disfunction level of the plexus in an anesthetical region. In a group with preganglionary root disfunction, 48% of the patient...
Autologous nerve grafting is the most commocommnlynly used operative technique in delayed primary, or secondary nerve repair after the peripheral nerve injuries. The aim of this procedure is to overcome nerve gaps that results from the injury itself, fibrous and elastic retraction forces, resection of the damaged parts of the nerve, position of the articulations and mobilisation of the nerve. In this study we analyse the results of operated patients with transections and lacerations of the peripheral nerves from 1979 to 2000 year. Gunshot injuries have not been analyzed in this study. The majority of the injuries were in the upper extremity (more than 87% of cases). Donor for nerve transplantation had usually been sural nerve, and only occasionally medial cutaneous nerve of the forearm was used. In about 93% of cases we used interfascicular nerve grafting, and cable nerve grafting was performed in the rest of them. Most of the grafts were 1 do 5 cm long (70% of cases). Functional recovery was achieved in more than 86% of cases, which is similar to the results of the other authors. Follow up period was minimum 2 years. We analyzed the influence of different factors on nerve recovery after the operation: patient's age, location and the extent (total or partial) of nerve injury, the length of the nerve graft, type of the nerve, timing of surgery, presence of multiple nerve injuries and associated osseal and soft tissue injuries of the upper and lower extremities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
