Idiopathic bilateral vocal fold weakness is an unrecognized clinical diagnosis. Bilateral laryngeal electromyography (EMG) is crucial for diagnosing vocal fold weakness when the cause is unknown.

Area of Science:

  • Otolaryngology
  • Neurology
  • Speech-Language Pathology

Background:

  • Bilateral vocal fold weakness presents a diagnostic challenge.
  • Idiopathic cases are often overlooked.
  • Comprehensive evaluation is necessary.

Observation:

  • A retrospective case study reviewed patients with bilateral laryngeal weakness.
  • Four patients were diagnosed with idiopathic bilateral vocal fold paresis.
  • Extensive workups included videostroboscopy and bilateral laryngeal electromyography (EMG).

Findings:

  • Bilateral laryngeal EMG is essential for diagnosing laryngeal weakness of unknown etiology.
  • Idiopathic bilateral vocal fold weakness is an underrecognized clinical entity.
  • Increased use of laryngeal EMG will improve diagnosis.

Implications:

  • This study highlights the importance of considering idiopathic bilateral vocal fold weakness.
  • Recommendations for diagnosis and management are proposed.
  • Laryngeal EMG is a key tool for identifying this condition.
