About this study

The primary purpose of this study will be to determine whether the proposed study protocol will allow for reliable detection of the human Laryngeal evoked brainstem responses (LEBR). Laryngeal evoked brain stem responses will be recorded from five test subjects under general anesthesia in the operating room with the assistance of an electrophysiologist with expertise in evoked potentials. Once the feasibility of obtaining tracings are established on the first few subjects, responses will be recorded from other test subjects with the aim of determining the optimal placement of stimulating electrodes and detection leads necessary to elicit an adequate response. The effect of varying the stimulus intensity will also be studied. Once parameters for testing have been standardized, normative configurations for the laryngeal evoked brainstem response tracings can be determined by patients both in the office setting and in the operating room.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Placement of a needle electrode through the thyrohyoid membrane into the submucosal space within the false vocal foldProcedure or surgery

Study groups in NCT02803359
Study groupRoleWhat they receive
Planned ProcedureExperimentalEndoscope will be connected to a camera and monitor. Needle electrodes will then be positioned into the false vocal fold mucosa bilaterally, under direct visualization of the needle tip on the monitor, but the needles will be passed trans-orally in the operating room. For those participating during an open-neck surgery, the surgery will commence as planned and once exposure of the superior laryngeal nerve is obtained, the surgeon will insert the electrodes directly into the nerve trunk for the purposes of recording. In Surgery or cervical lymphadenectomy, the electrode will be placed at a superficial depth and needle placement will be performed with one on each side at a location approximately mid-fold.
Receives: Procedure: Placement of a needle electrode through the thyrohyoid membrane into the submucosal space within the false vocal fold
Routine LaryngoscopyExperimentalNasolaryngoscopy will be performed in the office in the standard fashion with the use of oxymetazoline for topical decongestion of the nasal mucosa, In both settings, the electrode will be placed at a superficial depth and needle placement will be performed with one on each side at a location approximately mid-fold
Receives: Procedure: Placement of a needle electrode through the thyrohyoid membrane into the submucosal space within the false vocal fold

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. analysis of variance in brain auditory evoked response (BAER) measured using recording electroencephalography electrodes

    Distributions of latencies within this group will be examined to evaluate the appropriateness of standard assumptions regarding normality and constant variance, and transformations or non-parametric statistics will be considered as needed.

    Measured: One Year

Questions about this trial

What is this clinical trial studying?

A study testing Placement of a needle electrode through the thyrohyoid membrane into the submucosal space within the false vocal fold in people with Thyroidectomy, run by NYU Langone Health at 1 site 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 1 inclusion and 13 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 25 Aug 2020. 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 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.

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?

analysis of variance in brain auditory evoked response (BAER) measured using recording electroencephalography electrodes (time frame: One Year). It is what the study was designed to measure, not a finding.

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 25 Aug 2020.
