About this study

Official title: The Use of Human Acellular Dermal Matrix in the Prevention of Infraauricular Depressed Deformities and Frey's Syndrome Following Total Parotidectomy

The aim of the study was to explore whether human acellular dermal matrix (ADM) implantation could prevent infraauricular depressed deformities and Frey's syndrome following total parotidectomy.

Read the detailed description

Seventy patients who underwent total parotidectomy were selected for inclusion in the study. We analyzed 41 cases of total parotidectomy (control group) and 29 cases of simultaneous ADM implantation following total parotidectomy (ADM group) for infraauricular depressed deformities and the presence of gustatory flushing or sweating. The follow-up periods ranged from 6 months to 7 years.

The Results showed facial contours and bilateral symmetry improved after surgery in the ADM group. In the control group, an infraauricular depressed deformity was evident in all 41 cases. Frey's syndrome was recorded in one patient (3.4%) from the ADM group and 14 patients (34.1%) from the control group. No cases of immune rejection, infection, hematoma, or salivary fistula were observed in either group.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing ADM in people with Parotid Tumor, run by West China Hospital at 1 site in China.

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 2 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 11 Aug 2011. 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 China. 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 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?

infraauricular depressed deformities and the presence of gustatory flushing or sweating (time frame: from 6 months to 7 years after surgery). 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 NCT01414790, which also lists 1 linked publication.

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 11 Aug 2011.
