Summary
Supracricoid partial laryngectomy (SCPL) preserves the larynx in T2 glottic cancer. Key factors for better voice quality after SCPL include glottis closure and epiglottis length, guiding surgical technique improvements.
Area of Science:
- Otolaryngology
- Laryngeal Surgery
- Voice Science
Background:
- Supracricoid partial laryngectomy (SCPL) preserves the larynx in over 95% of T2 glottic carcinoma cases.
- Post-SCPL vocal cord absence impacts voice quality, a crucial aspect of patient life.
- Understanding post-surgical laryngeal function is vital for improving patient outcomes.
Purpose of the Study:
- To enhance vocal function following SCPL.
- To investigate the anatomical function of the post-SCPL larynx.
- To correlate anatomical findings with perceptual and instrumental voice assessments.
Main Methods:
- Twenty-five patients who underwent SCPL with cricoepiglottopexy for T2 glottic carcinoma were evaluated.
- Laryngostroboscopic examination assessed parameters like laryngeal occlusion, epiglottic length, arytenoid movement, and vibratory area.
- Voice samples underwent perceptual (GRBAS scale) and instrumental analysis (acoustic, aerodynamic parameters).
Main Results:
- Glottis occlusion and epiglottic length correlated with the general grade of dysphonia.
- Oral airflow was significantly correlated with laryngeal occlusion (P=0.006).
- Vibratory area presence correlated with voice roughness, shimmer, oral airflow, and signal-to-noise ratio.
Conclusions:
- Significant correlations exist between laryngostroboscopic findings and voice quality measurements.
- Glottis occlusion and epiglottic length are critical determinants of postoperative voice quality.
- Findings can inform surgical technique advancements to improve voice outcomes after SCPL.
