Collagen injection for vocal cord augmentation

1.1 Current evidence on collagen injection for vocal cord augmentation suggests that there are no major safety concerns and that it is efficacious in patients requiring short-term symptom relief. However, evidence on long-term efficacy is lacking.

1.2 Patients should be fully informed of the uncertainty about the procedure's long-term efficacy, and of the alternative treatment options. Use of NICE's information for the public is recommended.
