|November 1, 1986
Summary
CO2 laser cordectomy results in mild to moderate dysphonia for most patients, with severe voice issues in about 20%. This voice restoration outcome is better than standard cordectomy but less effective than radiotherapy.
Area of Science:
- Otolaryngology
- Laser Surgery
- Speech Science
Context:
- Evaluating patient voice quality after CO2 laser cordectomy.
- Comparing surgical outcomes with radiotherapy and standard cordectomy.
- Assessing the efficacy of Yanagihara's sonegraphic classification.
Purpose:
- To evaluate the voice outcomes of patients undergoing CO2 laser cordectomy.
- To compare the effectiveness of CO2 laser cordectomy with other treatment modalities.
- To recommend a standardized method for dysphonia classification in future studies.
Summary:
- Subjective assessment, voice parameter registration, and sonegraphic classification revealed closely concordant results.
- The primary outcome was a slight to medium degree of dysphonia.
- Severe dysphonia or aphonia was observed in approximately 20% of patients, indicating a functional voice impairment.
Impact:
- CO2 laser cordectomy offers a voice outcome superior to standard translaryngeal cordectomy.
- The results suggest CO2 laser cordectomy is a viable, albeit slightly less effective, alternative to radiotherapy for voice preservation.
- Yanagihara's sonegraphic classification is recommended for consistent evaluation in comparative voice studies.
