Radiotherapy for early-stage glottic tumors minimally impacts voice quality, with most patients reporting little vocal handicap. Objective and subjective assessments confirm good vocal function post-treatment.

Area of Science:

  • Otolaryngology
  • Radiation Oncology
  • Speech-Language Pathology

Background:

  • Voice quality is a crucial outcome measure for radiotherapy in glottic tumors.
  • Evaluating vocal function and patient self-perception is essential for treatment assessment.

Purpose of the Study:

  • To objectively assess vocal function after radiotherapy for early-stage glottic tumors.
  • To evaluate patients' self-perceived voice quality and handicap.

Main Methods:

  • 18 patients with early-stage glottic tumors treated with radiotherapy were studied.
  • Objective voice analysis and subjective voice quality assessments (examiner and patient) were performed.
  • The Voice Handicap Index questionnaire was used for patient self-evaluation.

Main Results:

  • 11% of patients had normal voices, while 44.4% experienced slight, 27.8% moderate, and 16.7% severe dysphonia.
  • Spectrographic analysis revealed 5.5% Grade I, 38.8% Grade II, and 27.7% each of Grade III and IV.
  • Patient-reported Voice Handicap Index scores were close to normal.

Conclusions:

  • Acoustic analysis indicates minimal vocal damage after radiotherapy for T1 laryngeal carcinoma.
  • Patients treated with radiotherapy for early-stage glottic tumors experience minimal voice-related handicap.
