Summary
Many patients with paradoxical vocal fold dysfunction (PVFD) have co-occurring laryngeal abnormalities, especially those with exercise-induced symptoms. Laryngoscopy is crucial for diagnosing and managing PVFD patients with these associated conditions.
Area of Science:
- Otolaryngology
- Pulmonology
- Speech-Language Pathology
Background:
- Paradoxical vocal fold dysfunction (PVFD) is a condition characterized by abnormal adduction of the vocal folds during respiration.
- The presence and impact of concomitant laryngeal abnormalities in PVFD patients require further investigation.
Purpose of the Study:
- To investigate the prevalence of laryngeal abnormalities in patients diagnosed with paradoxical vocal fold dysfunction (PVFD).
Main Methods:
- Retrospective chart review of 30 patients evaluated for PVFD between July and December 2002.
- Data collection included patient history, symptoms, comorbidities (asthma, GERD), and laryngoscopic findings.
- Diagnosis of PVFD was based on patient history and laryngoscopy; exercise stress tests were performed when indicated.
Main Results:
- A significant female predominance (90%) was observed, with a mean age of 28 years.
- The median duration of symptoms before diagnosis was 4.5 years.
- Commonly observed abnormalities included findings suggestive of gastroesophageal reflux disease (53%), chronic laryngitis (12%), asthma (56%), and other laryngeal issues (33%) in the exercise-induced group.
Conclusions:
- Concomitant laryngeal abnormalities are frequent in patients with PVFD, particularly in those experiencing exercise-induced symptoms.
- Laryngoscopy plays a vital role in the comprehensive evaluation and management of patients with PVFD.
- Identifying these co-occurring conditions is essential for effective treatment strategies.
