What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Hemifacial atrophy causes one side of the face to shrink, creating an uneven appearance. Surgeons often use fat grafting or free flap reconstruction to restore volume, but it's not clear how much symmetry actually improves. This study looks back at 60 patients treated between 2020 and 2023, using 2D photos and 3D scans to measure changes in facial symmetry at least 6 months after surgery. The goal is to compare which surgical method leads to better symmetry and fewer complications.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Patients with hemifacial atrophy treated at a single center between January 2020 and December 2023 who underwent initial facial volume restoration using autologous fat grafting or free-flap reconstruction. Outcomes were assessed preoperatively and at the first follow-up visit ≥6 months postoperatively. Three-dimensional surface scan analysis was performed in a subset with available 3D data.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: Diagnosis of hemifacial atrophy (Parry-Romberg syndrome). Underwent initial soft-tissue augmentation with either autologous fat grafting or free-flap reconstruction at the study center between January 2020 and December 2023. Availability of standardized preoperative assessment and postoperative assessment at the first follow-up visit occurring ≥6 months after surgery (2D photographs required). Exclusion Criteria: Follow-up \<6 months after the initial surgery. Missing key imaging/photographic data required for outcome assessment. Any additional facial augmentation or revision procedure performed before the first ≥6-month follow-up visit.
