Facial palsy is a relatively common condition, from which most cases recover spontaneously. However, each year, there are 127,000 new cases of irreversible facial paralysis. This condition causes aesthetic, functional and psychologically devastating effects in the patients who suffer it. Various reconstructive techniques have been described, but there is no consensus regarding their indication. While these techniques provide results that are not perfect, many of them give a very good aesthetic and functional result, promoting the psychological, social and labour reintegration of these patients. The aim of this article is to describe the indications for which each technique is used, their results and the ideal time when each one should be applied., (Copyright © 2014 Sociedad Española de Neurocirugía.

Background: Thoracic Outlet Syndrome is a compression of the brachial plexus that remains highly controversial. Classification in True or Neurogenic Outlet (TTO) and Disputed or Non-neurogenic Outlet (DTO) is becoming very popular. The former is characterized by a muscular atrophy of the intrinsic muscles of the hand, while the latter has only sensitive symptoms. The purpose of this article is to analyze the results obtained in a series of 31 patients., Methods: All patients with diagnosis of Thoracic Outlet operated between January 2003 and December 2012 with a minimum follow-up of six months where included. Age, sex, symptoms, classification, preoperative studies results, complications and recurrences were analyzed., Results: 31 surgeries performed in 30 patients, 9 with TTO (8 women, mean age 24.3 years) and 21 with DTO (18 women, mean age 37.4 years, 1 recurrence) were included. Ninety percent of patients presented neurophysiological and 66.6% imagenological preoperative disturbances. All TTO and only 36.7% of DTO showed clear pathological findings during surgical exploration. A high percentage (87,5% sensitive and 77.7% motor) of TTO ameliorated after surgical decompression. Only 45.5% of DTO showed permanent positive changes, 13.6% temporary, 36.6% no changes, and 4.5%(one case) showed deterioration after decompresive surgery. Complications after surgery were more frequent –but temporary- in TTO cases (33.3%), than in DTO (13.6%)., Conclusions: TTO showed a favorable outcome after surgery. DTO showed a worst –but still positive- postoperative result if patients are selected properly. These data are in concordance with other recent reports.

Objective: To analyze the results of an initial series of four cases of traumatic injuries of the axillary nerve, treated by a nerve transfer from the triceps long branch of the radial nerve. An extensive analysis of the literature has also been made., Materials and Methods: Four patients aged between 21 and 42 years old presenting an isolated traumatic palsy of the axillary nerve were operated between January 2007 and June 2010. All cases were treated by nerve transfer six to eight months after the trauma. The results of these cases are analyzed, the same as the axillary nerve injuries series presented in the literature from 1982., Results: One year after the surgery, all patients improved their abduction a mean of 70° (range 30 to 120°), showing a M4 in the British Medical Council Scale. No patient complained of triceps weakness after the procedure. These results are similar to those published employing primary grafting for the axillary nerve., Conclusions: Isolated injuries of the axillary nerve should be treated with surgery when spontaneous recovery is not verified 6 months after the trauma. Primary repair with grafts is the most popular surgical technique, with a rate of success of approximately 90%. The preliminary results of a nerve transfer employing the long triceps branch are similar, and a definite comparison of both techniques with a bigger number of cases should be done in the future., (Copyright © 2012 Sociedad Española de Neurocirugía.

After the great enthusiasm generated in the '70s and '80s in brachial plexus surgery as a result of the incorporation of microsurgical techniques and other advances, brachial plexus surgery has been shaken in the last two decades by the emergence of nerve transfer techniques or neurotizations. This technique consists in sectioning a donor nerve, sacrificing its original function, to connect it with the distal stump of a receptor nerve, whose function was lost during the trauma. Neurotizations are indicated when direct repair is not possible, i.e. when a cervical root is avulsed at its origin in the spinal cord. In recent years, due to the positive results of some of these nerve transfer techniques, they have been widely used even in some cases where the roots of the plexus were preserved. In complete brachial plexus injuries, it is mandatory to determine the exact number of roots available (not avulsed) to perform a direct reconstruction. In case of absence of available roots, extraplexual nerve transfers are employed, such as the spinal accessory nerve, the phrenic nerve, the intercostal nerves, etc., to increase the amount of axons transferred to the injured plexus. In cases of avulsion of all the roots, extraplexal neurotizations are the only reinnervation option available to limit the long-term devastating effects of this injury. Given the large amount of reports that has been published in recent years regarding brachial plexus traumatic injuries, the present article has been written in order to clarify the concerned readers the indications, results and techniques available in the surgical armamentarium for this condition. Since the choice of either surgical technique is usually taken during the course of the procedure, all this knowledge should be perfectly embodied by the surgical team before the procedure. In this first part extraplexual nerve transfers are analyzed, while intraplexual nerve transfers will be analyzed in the second part of this presentation.

In a previous paper extraplexual nerve transfers were analyzed; this literature review complements the preceding paper analyzing intraplexual nerve transfers, and thus completing the analysis of the nerve transfers available in brachial plexus surgery.
