“…They reported a 90.9% probability that a person will not recovery motion if they demonstrate evidence of “high grade injury” on EMG, but that EMG was an indifferent predictor of recovery (55.6%). 22 It was therefore argued that patients demonstrating presence of spontaneous activity 55–59 or absence or reduced motor unit potentials 56,57,60–62 at 6 months may be good candidates for early intervention. 22 …”

Laryngeal framework surgery is the current gold standard treatment for unilateral vocal fold paralysis. It provides a permanent solution to glottic insufficiency caused by injury to the recurrent laryngeal nerve. Various modifications to the original Isshiki type I laryngoplasty procedure have been described to improve voice and swallowing outcomes. The success of this procedure is highly dependent on the experience of the surgeon as it epitomizes the intersection of art and science in the field. The following article reviews the evidence, controversies, and complications related to laryngoplasty for unilateral vocal fold paralysis. It also provides a detailed analysis of how and when arytenoid-positioning procedures should be considered, and summarizes the literature on postoperative outcomes.

“…This diagnosis method has been recognized since 1944 by Weddel and there is an important research regarding its application. Even if it has been performed since the 1950s 2 , its practical clinical importance has been emphasized only since the last three decades of the twentieth century 2,3 . The variations of the technique implemented over time, the variability patterns of the study, the different…”

Clinical application of laryngeal electromyography – a point of view

In recent years, the clinical importance of laryngeal electromyography (LEMG) has been recognized. This method of investigation proved itself to be a valuable and indispensable tool regarding voice disorder management and requires multidisciplinary approach. In this article, we focus on the clinical usefulness of LEMG to assess inferior and superior motor neuron integrity by recording action potentials generated by muscle fibers of the larynx in the new field known as neurolaryngology. To facilitate the clinical application of this electrophysiologic test, we present a detailed description of LEMG techniques, which were applied for simultaneous bilateral recordings of the thyroarytenoid, cricothyroid and posterior cricoarytenoid muscles. Also, we analysed and measured the following electrophysiological parameters: 1) insertional activity; 2) spontaneous activity; 3) recruitment; 4) morphology of waveform. From a practical point of view, in our country, LEMG performance is still not a routine procedure in ENT and Phoniatric Departments. The difficulty of practical use of LEMG in Romania consists in technical limitations and it depends on the physician’s experience regarding the examination technique and also the interpretation of electrophysiological results. Our current clinical experience shows that the use of LEMG contributes especially to the diagnosis, prognosis and treatment of patients with neurolaryngological disorders.

“…In addition to this activity in the central nervous system, they have been shown promise in multiple rodent models as a possible pharmacologic treatment for facial nerve injury [6][7][8][9][10]. To the best knowledge of the authors, the literature is poor regarding the beneficial local effects of gallopamil (a calcium channel blocker) on transected sciatic nerve.…”
