Summary
Patients reporting vocal effort (VE) experience a greater voice handicap than those with vocal quality (VQ) issues. This study highlights how VE significantly impacts quality of life, regardless of VQ complaints.
Area of Science:
- Otolaryngology
- Speech-Language Pathology
- Voice Science
Background:
- Vocal effort (VE) is a common symptom in voice disorders.
- Understanding patient-reported outcomes is crucial for voice disorder management.
- The Voice Handicap Index (VHI) and Glottal Function Index (GFI) are key assessment tools.
Purpose of the Study:
- To compare Voice Handicap Index (VHI) scores in patients with primary complaints of vocal effort (VE) versus vocal quality (VQ) and combined VE and VQ.
- To compare Glottal Function Index (GFI) and glottic closure patterns across these complaint groups.
Main Methods:
- A prospective outcomes database was used, analyzing 713 patients categorized by presenting complaints (VQ, VE, VQ+VE) and laryngeal pathology.
- VHI and GFI scores were compared between complaint groups.
- Relationships between complaint categories, laryngeal pathology, and glottic closure were assessed.
Main Results:
- Significant differences in VHI were found across all complaint groups (P < 0.0001).
- Patients with VE-only complaints reported higher VHI scores than VQ-only.
- GFI was significantly higher in VE-only patients compared to VQ-only (P < 0.001). Glottic closure patterns were not significant.
Conclusions:
- Vocal effort (VE) complaints significantly impact quality of life, even without vocal quality (VQ) issues.
- Patients with VE perceive greater glottic dysfunction.
- Altered glottic function may underlie increased VE, but direct correlation with glottic closure was not established.
