Summary
Supraglottic surgery for laryngeal cancer impacts voice quality, altering vocal color. Patients experienced temporary dysphagia and required longer tracheostomy, delaying voice rehabilitation.
Area of Science:
- Otolaryngology
- Speech-Language Pathology
- Medical Acoustics
Context:
- Assessing voice quality in laryngeal cancer patients pre- and post-surgery.
- Utilizing subjective and objective spectrography for dysphonia evaluation.
Purpose:
- To investigate the effects of supraglottic surgery on voice quality in laryngeal cancer patients.
- To analyze spectrographic changes in voice production following the procedure.
Summary:
- Voice quality changes were observed in 37 laryngeal cancer patients after supraglottic surgery.
- Spectrography revealed decreased formant levels (F3, F4), indicating altered voice color.
- Temporary complications included dysphagia and prolonged tracheostomy, impacting rehabilitation timelines.
Impact:
- Provides insights into the vocal consequences of laryngeal cancer treatment.
- Highlights the need for tailored post-operative voice and swallowing rehabilitation strategies.
- Contributes to understanding spectrographic voice analysis in oncologic surgery outcomes.
