Summary
Injecting absorbable gelatin powder is a safe, short-term vocal cord paralysis treatment. This method is suitable for temporary paralysis when function is expected to return within a year.
Area of Science:
- Otolaryngology
- Speech and Hearing Science
Background:
- Historically, paraffin injections treated glottic insufficiency from vocal cord paralysis.
- Modern techniques utilize absorbable gelatin powder for vocal cord augmentation.
Purpose of the Study:
- To evaluate absorbable gelatin powder injection as a treatment for transient vocal cord paralysis.
Main Methods:
- Intralaryngeal injection of absorbable gelatin powder into the affected vocal cord.
Main Results:
- This procedure is an acceptable short-term solution for unilateral vocal cord paralysis.
- Complications associated with this method are relatively uncommon.
Conclusions:
- Absorbable gelatin powder injection is a viable option for temporary vocal cord paralysis.
- It is particularly indicated when vocal cord function is anticipated to recover within one year.
