Total Versus Partial Arytenoidectomy in Bilateral Vocal Fold Paralysis
A study testing Total arytenoidectomy and Partial arytenoidectomy in people with Airway Obstruction and Vocal Cord Paralysis, run by Hacettepe University at 1 site in Turkey (Türkiye).
Trial summary
Total arytenoidectomy is claimed to increase risk of aspiration and cause more voice loss than other operations performed for bilateral vocal fold paralysis (BVFP). However, objective evidence for such conclusion is lacking. There is no study comparing swallowing and voice after total and partial arytenoidectomy. Read more about this study

About this study
Official title: The Comparison of Voice and Swallowing Parameters After Endoscopic Total and Partial Arytenoidectomy Using Medially Based Mucosal Advancement Flap Technique for Bilateral Abductor Vocal Fold Paralysis: A Randomized Trial
Total arytenoidectomy is claimed to increase risk of aspiration and cause more voice loss than other operations performed for bilateral vocal fold paralysis (BVFP). However, objective evidence for such conclusion is lacking. There is no study comparing swallowing and voice after total and partial arytenoidectomy.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Total arytenoidectomy is claimed to increase risk of aspiration and cause more voice loss than other operations performed for bilateral vocal fold paralysis (BVFP). However, objective evidence for such conclusion is lacking. There is no study comparing swallowing and voice after total and partial arytenoidectomy.

Questions about this trial
What is this clinical trial studying?
A study testing Total arytenoidectomy and Partial arytenoidectomy in people with Airway Obstruction and Vocal Cord Paralysis, run by Hacettepe University at 1 site in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 5 Apr 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Decannulation (time frame: From the day of operation until 52 weeks after arytenoidectomy). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01824849, which also lists 13 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Apr 2013; AzTrials last refreshed its copy on 1 Nov 2026.
