Trial summary

Unilateral vocal fold paralysis (UVFP) is caused by injury to the nerve to the affected vocal fold. The injury to the vocal fold makes the affected person's voice sound "breathy". Voice therapy is usually tried first, and, if unsuccessful, surgical treatment is considered. Read more about this study

About this study

Official title: Medialization Vs Reinnervation for Vocal Cord Paralysis

Unilateral vocal fold paralysis (UVFP) is caused by injury to the nerve to the affected vocal fold. The injury to the vocal fold makes the affected person's voice sound "breathy". Voice therapy is usually tried first, and, if unsuccessful, surgical treatment is considered. The standard surgical treatment is called vocal fold medialization and aims to bring the injured cord to the midline. An alternative surgical treatment, vocal fold reinnervation, aims to bring a new nerve supply to the injured vocal fold. The reinnervation operation, which has some potential advantages over the medialization operation also requires several months for final results to be gained. The goal of this multicenter, randomized clinical trial is to see which of the two surgical treatments produces a better outcome.

In order to participate in this study patients with UVFP must meet all entry criteria and must be released from voice therapy by a speech-language pathologist. Information collected for the study (pre-surgery, and at 6 and 12 months after surgery) includes voice recordings, movies made of vocal fold function, airflow and pressure measurements of the voicebox, and an outcomes questionnaire.

Read the detailed description

Unilateral vocal fold paralysis (UVFP) is caused by injury to the recurrent laryngeal nerve. Patients with UVFP may have significant impairment of vocal fold function, including a breathy paralytic dysphonia. There are several available approaches for the treatment of this condition. Vocal fold medialization is currently used by most otolaryngologists and is probably the standard of care for treating UVFP. An alternative approach is laryngeal reinnervation, which has a number of potential advantages over medialization but which requires several months before a final result is achieved. The primary goal of this multicenter, randomized clinical trial is to determine which approach produces a better outcome.

Patients with UVFP meeting all inclusion criteria and released from therapy by a speech-language pathologist will be randomized into either the medialization arm or the reinnervation arm. The data collection protocol consists of voice recordings, aerodynamic measurements, electroglottography, videostroboscopy, and a clinical outcomes questionnaire collected pre-treatment and at 6 and 12 months post-treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing vocal fold medialization and vocal fold reinnervation in people with Unilateral Vocal Cord Paralysis, run by National Institute on Deafness and Other Communication Disorders (NIDCD) at 12 sites in United States.

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 9 inclusion and 4 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: stopped early, as of the sponsor's last update on 24 Apr 2006. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United States. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early. Results are not available in the source record.

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.

Where can I read the original study information?
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 24 Apr 2006; AzTrials last refreshed its copy on 28 Oct 2026.
