Larynx01:21

Larynx

3.5K
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,...

Myasthenia Gravis: Diagnostic Tests

1.7K
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...

Area of Science:

  • Neurolaryngology
  • Diagnostic tools
  • Clinical trials

Background:

  • Laryngeal electromyography (LEMG) is crucial for diagnosing and managing laryngeal disorders.
  • Recent clinical trials have focused on advancing LEMG applications and interpretation.

Purpose of the Study:

  • To review recent advancements in Laryngeal electromyography (LEMG) over the past five years.
  • To highlight the expanding role of LEMG in diagnosing vocal fold paralysis and other laryngeal conditions.

Main Methods:

  • Review of clinical trials and published literature on Laryngeal electromyography (LEMG) from the last 5 years.
  • Analysis of studies focusing on diagnostic accuracy, prognostic value, and new applications of LEMG.

Main Results:

  • Standardized LEMG performance guidelines have been established, improving result comparability.
  • LEMG applications have expanded beyond the thyroarytenoid muscle to include the posterior cricoarytenoid and cricothyroid muscles.
  • Multichannel LEMG enables intraoperative nerve monitoring during thyroid surgery.

Conclusions:

  • LEMG is a valuable tool for differentiating functional from organic laryngeal disorders, primarily vocal fold paralysis.
  • LEMG provides crucial prognostic information for vocal fold paralysis recovery.
  • Emerging applications include laryngeal pacing, guided injections, and electrostimulation.
