Larynx01:21

Larynx

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...
Skeletal Muscle Relaxants: Therapeutic Uses01:31

Skeletal Muscle Relaxants: Therapeutic Uses

Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx as...

Area of Science:

  • Neurology
  • Speech Pathology
  • Genetics
  • Neuroscience

Background:

  • Spasmodic dysphonia (SD) is a chronic, debilitating voice and speech disorder.
  • Current understanding of SD pathogenesis, diagnosis, and treatment requires enhancement.

Purpose of the Study:

  • To identify critical research priorities for spasmodic dysphonia.
  • To advance the understanding of SD pathogenesis, diagnosis, and treatment.

Main Methods:

  • A multidisciplinary working group of scientists and clinicians was assembled.
  • The group reviewed existing information on spasmodic dysphonia.
  • Research priorities were identified through expert consensus.

Main Results:

  • Operational definitions for diagnosing spasmodic dysphonia were recommended.
  • A multicenter, multidisciplinary validation study was proposed.
  • Key research areas include disorder characterization and risk factor identification.

Conclusions:

  • Further research is needed to characterize spasmodic dysphonia and its risk factors.
  • Comparative studies with other focal dystonias and development of animal models are recommended.
  • Enhanced understanding of SD pathophysiology will guide new treatment development and clinical trials.
