|August 1, 1979
Summary
Abductor type spastic dysphonia is poorly understood compared to other vocal cord disorders. This report details two cases, exploring potential spasticity and age-related factors in abductor spastic dysphonia.
Area of Science:
- Laryngology
- Speech-Language Pathology
- Neurology
Background:
- Abductor type spastic dysphonia (ABSD) is less defined than adductor spastic dysphonia or vocal cord paralysis.
- Limited research exists on the specific characteristics and etiology of ABSD.
Observation:
- Presents voice symptoms, spectrographic data, and indirect laryngoscopic findings.
- Details case histories of two patients diagnosed with ABSD.
Findings:
- Investigates the potential presence of a spastic component in ABSD.
- Examines if a specific age demographic is predominantly affected by ABSD.
Implications:
- Highlights the need for further research into ABSD.
- Aims to improve the understanding and diagnosis of this vocal cord disorder.
