A Novel Method: Super-selective Adrenal Venous Sampling
Published on: September 15, 2017
Summary
This study modified the Asai procedure for post-laryngectomy speech, achieving initial voice but ultimately failing due to complications. Further research is needed to improve alaryngeal speech methods.
Area of Science:
- Laryngology
- Speech Rehabilitation
- Surgical Innovation
Background:
- Esophageal speech is challenging for some post-laryngectomy patients.
- Alternative methods are needed to restore voice after total laryngectomy.
Purpose of the Study:
- To evaluate a modified Asai procedure using a Silastic prosthesis for speech restoration.
- To assess the efficacy and complications of this novel surgical technique.
Main Methods:
- A modified Asai procedure with a custom Silastic prosthesis was performed on three female patients.
- Speech outcomes and complications were monitored post-operatively.
Main Results:
- All patients experienced immediate voice return and initial satisfaction.
- Complicating factors led to revision surgery in all cases, rendering the method a failure.
Conclusions:
- The modified Asai procedure with this specific prosthesis was unsuccessful in achieving long-term speech restoration.
- Further investigation into surgical modifications for alaryngeal speech is warranted.
