Full Description
With 52 videos and 47 audio files, bringing LEMG concepts and techniques to life!
Authored by an esteemed team of international experts, Laryngeal Electromyography: Case Studies is the first-of-its-kind book to present multidisciplinary cases on the clinical application of laryngeal electromyography (LEMG), including key concepts and principles of LEMG interpretation. It discusses diagnostic and therapeutic approaches to treating voice disorders. It also describes electrode placement, signal interpretation, and analysis techniques specific to each of the laryngeal muscles. The book highlights how LEMG is used to diagnose neuromuscular diseases of the intrinsic laryngeal muscles, generalized neurologic disorders, monitor ongoing treatment plans, and determine the effectiveness of interventions.
The text includes 21 detailed and illustrated case examples with multimedia, showing how LEMG guides patients and physicians in clinical practice to evaluate a variety of problems, including differentiating vocal fold paralysis from mechanical fixation, laryngeal myopathy, myasthenia gravis, motor neuron disease, and others. It also includes instruction and nuances of laryngeal EMG for intraoperative nerve monitoring and needle guidance during the injection of botulinum toxin.
This essential guide empowers otolaryngologists, laryngologists, and voice specialists to harness the full potential of LEMG for diagnosing and managing voice disorders. Whether you are experienced in LEMG or considering its incorporation into your practice, this book offers invaluable insights and case descriptions from experts, sharing their hands-on expertise to enhance patient outcomes and clinical decision-making.
