Cordectomy surgery alters the glottic sphincter, leading to varied dysphonia. Scarring patterns and patient compensation determine voice outcomes after this vocal cord surgery.

Area of Science:

  • Laryngology
  • Speech and Voice Science

Background:

  • Cordectomy, a surgical procedure involving vocal cord removal, often results in glottic sphincter alteration.
  • This alteration impacts overall laryngeal function, leading to diverse forms of dysphonia.

Observation:

  • Voice typology in cordectomized patients can be studied using psycho-acoustic analysis, video-fiber-laryngoscopy, and spectrographic analysis.
  • Dysphonia types depend on scarring patterns, surgical extent, and laryngeal positioning during phonation.

Findings:

  • The study analyzes how different scarring patterns and compensatory mechanisms influence voice quality post-cordectomy.
  • Clinical cases demonstrate varying phonatory capabilities based on the extent of cordectomy, including extensions to the ventricle and false vocal cords.

Implications:

  • Understanding these dynamics aids in predicting and managing voice outcomes for cordectomized patients.
  • This research highlights the importance of individualized assessment and rehabilitation strategies for dysphonia following cordectomy.
