Trial summary

This study will use stereo photogrammetry to: 1) characterize facial features of genetic and congenital malformations; 2) define facial features associated with normal growth and development; and 3) determine if stereo photogrammetry soft tissue imaging can be used to help diagnose head and facial malformations.

About this study

Official title: Stereo Photogrammetry Soft Tissue in Normal Individuals and Patients With Craniofacial Dysmorphologies

This study will use stereo photogrammetry to: 1) characterize facial features of genetic and congenital malformations; 2) define facial features associated with normal growth and development; and 3) determine if stereo photogrammetry soft tissue imaging can be used to help diagnose head and facial malformations. These abnormalities currently are diagnosed using 2- or 3-dimensional skeletal images obtained with x-rays. Stereo photogrammetry uses a camera and computer to generate 3-dimensional images of the soft tissues of the face. Because the method does not use any radiation, images can be taken repeatedly to evaluate patients over a long term.

Using stereo photogrammetry, images of people who belong to a defined group, for example, 17-year-old Caucasian males, can be combined (or morphed) into one image, allowing measurement of the facial features of the group. Comparing the morphed images of a normal control group with those of people with specific genetic conditions may reveal distinctions that could be used in diagnosing conditions that are currently diagnosed using x-rays.

Healthy normal volunteers and patients with craniofacial dysmorphologies may be eligible for this study. Patients are recruited from current NIH studies of various genetic diseases. People who have previously had head and neck surgeries, including cosmetic surgery, may not participate.

Participants give a medical and dental history, including any orthodontic work or facial surgeries. They are then positioned in front of a photogrammetry camera, a headband is placed on their head, and their picture is taken. A coded patient number is entered into the computer, where the image is stored until further analysis. Most participants are evaluated one time, but some patients and control subjects may be asked to return yearly for repeat images.

Read the detailed description

In previous decades, analysis of craniofacial dysmorphologies have been conducted using two- or three-dimensional imaging of skeletal tissues acquired through radiography, with little analysis of soft tissue structures. The advantages of stereophotogrammetry surface scanning include easy image acquisition, the procedure is non-invasive, and images may be easily repeatedly taken for longitudinal evaluation of facial morphology. No radiation is used in acquiring these images.

The purposes of this study are to: 1) characterize the surface tissue facial features in different genetic diseases and syndromes; 2) define facial parameters of age-related growth and development; and 3) establish the use of stereophotogrammetry surface tissue imaging in aiding the diagnosis of genetic conditions and prediction of the clinic course of craniofacial dysmorphologies and associated genotypes.

Procedures will entail the acquisition of facial images from patients with known and suspected dysmorphologies as well as healthy controls. Facial parameters of various patient groups will be characterized in a standardized manner. In addition, composite (mean) images of patients with a particular diagnosis will be compared with controls using software algorithms. These facial parameters will be used to calculate the sensitivity and specificity of this technology to predict the genetic dysmorphology.

Questions about this trial

What is this clinical trial studying?

An observational study of Craniofacial Abnormalities, run by National Institute of Dental and Craniofacial Research (NIDCR) at 3 sites in 3 countries.

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 3 inclusion and 2 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 4 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States, Brazil, Peru. 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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00100529, which also lists 3 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 4 Dec 2019.
