Voice quality after transoral laser surgery for glottic cancer depends on phonation mechanism and anterior commissure preservation, not tissue amount. Speech therapy showed no significant benefit in this study.

Area of Science:

  • Otolaryngology
  • Speech-Language Pathology
  • Oncology

Context:

  • Transoral endolaryngeal laser surgery is used for early glottic cancer.
  • Voice quality is a crucial factor for effective communication post-surgery.
  • Understanding factors influencing voice outcomes is essential for patient management.

Purpose:

  • To investigate voice quality after transoral endolaryngeal laser surgery.
  • To identify the influence of surgery type and extent on postoperative voice parameters.
  • To assess the role of the anterior commissure and speech therapy on voice outcomes.

Summary:

  • Voice quality was assessed using videostroboscopy, relative phonetogram (RP), and expert ratings (TO, ST).
  • Preservation of the anterior commissure significantly improved voice parameters (RP, TO, ST).

  • Extended cordectomy and transglottic resection resulted in poorer voice quality.
  • Speech therapy did not yield significant improvements in voice parameters.

    • Impact:

    • Postoperative phonatory results correlate with the mechanism of phonation and anterior commissure preservation.
    • Relative phonetogram (RP) is an effective tool for voice assessment.
    • Findings guide surgical decisions to optimize voice outcomes in glottic cancer patients.
