Summary

Physical examination of laryngeal movement during swallowing aids in assessing oropharyngeal swallowing disorders. This noninvasive method detects defective laryngeal motion and associated functional impairments, aiding dysphagia evaluation.

Area of Science:

  • Otolaryngology
  • Gastroenterology
  • Neurology

Background:

  • Swallowing disorders (dysphagia) affect the oropharyngeal region.
  • Accurate assessment of laryngeal function during deglutition is crucial for diagnosing dysphagia.
  • Current diagnostic methods may not fully capture the nuances of laryngeal mobility.

Purpose of the Study:

  • To evaluate the utility of physical palpation and measurement of laryngeal movement during swallowing.
  • To establish normal laryngeal elevation values for comparison.
  • To identify abnormal laryngeal motion and displacement in patients with dysphagia.

Main Methods:

  • Physical examination involving measurement and palpation of the larynx during deglutition.
  • Study included 14 patients with dysphagia and two normal control groups.
  • Normal laryngeal elevation values were established from control groups.

Main Results:

  • Normal laryngeal elevation ranged from 1.80 to 2.50 cm.
  • Eight dysphagic patients exhibited defective laryngeal motion (0 to 1.50 cm).
  • Anomalous displacements like lateral shifting and lowering of the larynx were observed; impaired pharyngeal and upper esophageal sphincter function noted in some patients.

Conclusions:

  • Direct measurement and palpation of laryngeal mobility is a noninvasive method for evaluating dysphagia.
  • This physical assessment aids in identifying aspiration risk and monitoring disorder evolution.
  • The method reveals subtle laryngeal dysfunctions and associated functional impairments.
