Vocal fold paresis (VFP) is often missed but diagnosed with electromyography. Surgical treatments like laryngoplasty offer significant vocal improvement for many patients.

Area of Science:

  • Otolaryngology
  • Neurology

Background:

  • Vocal fold paresis (VFP) is a common condition often difficult to diagnose solely through laryngeal examination.
  • Accurate diagnosis is crucial for effective treatment and patient outcomes.

Observation:

  • A retrospective review analyzed 50 adult patients diagnosed with VFP via laryngeal electromyography (LEMG).
  • Common symptoms included dysphonia (100%), vocal fatigue (76%), and diplophonia (40%).
  • Observed laryngeal findings were unilateral vocal fold hypomobility (50%) and vocal fold bowing (36% unilateral, 22% bilateral).

Findings:

  • LEMG is the definitive diagnostic tool for VFP, essential when clinical examination is inconclusive.
  • VFP may be underdiagnosed due to compensatory hyperkinetic disorders masking the condition.

  • Surgical interventions, including laryngoplasty and lipoinjection, were performed on 54% of patients.

    • Implications:

    • 85% of patients undergoing surgery reported significant vocal improvement, indicating treatment efficacy.
    • LEMG confirmation is vital for accurate VFP diagnosis.
    • Surgical treatment for VFP is safe and effective, improving vocal function.
