Summary
Functional electrical stimulation offers a new dynamic approach for vocal fold motion impairment. Laryngeal pacing is becoming clinically applicable for rehabilitating patients with bilateral vocal fold paralysis.
Area of Science:
- Laryngology
- Neuromodulation
- Rehabilitation Medicine
Background:
- Vocal fold paralysis, often due to recurrent laryngeal nerve damage, results in impaired vocal fold motion.
- Accurate diagnosis of vocal fold paralysis requires laryngeal electromyography.
- Current treatments for bilateral vocal fold motion impairment are limited.
Purpose of the Study:
- To review the scientific basis of functional electrical stimulation for the larynx.
- To assess the current status of animal studies on laryngeal pacing.
- To examine initial clinical applications of laryngeal pacing.
Main Methods:
- Literature review of functional electrical stimulation and laryngeal pacing.
- Analysis of animal pacing trials.
- Evaluation of early clinical attempts at laryngeal pacing.
Main Results:
- Animal trials demonstrate the feasibility of laryngeal pacing for bilateral vocal fold motion impairment.
- Laryngeal pacing is now clinically viable due to minimally invasive electrode placement and advanced stimulation circuits.
- Functional electrical stimulation is a promising dynamic rehabilitation strategy.
Conclusions:
- Laryngeal pacing represents a significant advancement in the dynamic rehabilitation of the larynx.
- This approach holds promise for patients with bilateral vocal fold motion impairment.

01:21Larynx
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

01:30Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...
01:14Ventilatory Modes
Mechanical ventilators are life-saving devices that support or replace spontaneous breathing. They deliver breaths to patients through varying methods known as ventilator modes. Understanding these modes is critical for healthcare providers managing patients with respiratory failure.
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...

01:22Cardiopulmonary Resuscitation II: ACLS Airway Management
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under...
01:29Mechanical Ventilation I: Indication and Settings
Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...
01:24Physical Assessment of the Respiratory Tract II: Palpation
Physical assessment of the respiratory tract is critical in identifying potential health issues. One key component of this assessment is palpation, a technique healthcare providers use to assess the body for abnormalities. This content explores the method of palpation in evaluating the respiratory tract, focusing on thoracic palpation and tactile fremitus.
Thoracic Palpation
Thoracic palpation detects tenderness, masses, lesions, respiratory excursions, and vocal fremitus. The nurse assesses...
