Temporary hair loss after injection of hyaluronic acid filler.

BACKGROUND

Compromised blood flow after filler injection is generally thought to result from intra-arterial obstruction.

AIMS: To test this hypothesis.

PATIENT: A case presented with the clinical picture of reduced arterial blood flow after hyaluronic acid filler injection in the temporal region and subsequent hair loss.

METHOD: Clinical and ultrasound (US) assessments as well as ultrasound guided hyaluronidase injection were performed.

RESULT: Blood flow was restored and hair loss proved to be temporary.

CONCLUSION

There are many arguments to conclude that the problem did not result from intra-arterial occlusion, but rather from outside compression of the artery.
