Summary
Even without voice complaints, long-term smokers show vocal fold changes and abnormal fundamental frequency variation. This indicates subclinical voice issues in chronic smokers.
Area of Science:
- Otolaryngology
- Speech and Language Pathology
Context:
- Chronic tobacco use is prevalent globally.
- Smokers often deny subjective voice complaints despite potential laryngeal changes.
Purpose:
- To assess voice parameters in smokers without self-reported voice disorders.
- To identify objective laryngeal and acoustic changes associated with chronic smoking.
Summary:
- Videolaryngostroboscopy revealed organic dysphonia-like changes in the larynx of 20 long-term smokers.
- Acoustic voice analysis showed abnormal Fundamental Frequency Variation (vFo) and reduced fundamental frequency.
Impact:
- Highlights the subclinical impact of smoking on voice production.
- Suggests routine voice screening may be beneficial for chronic smokers.
- Provides objective data on smoking-related vocal changes.
