Photobiomodulation Therapy in the Management of Late Complications After Facial Filling

The aim of the present study is to report a clinical case of a patient diagnosed with a late adverse reaction to the injection of filler material - persistent and intermittent delayed swelling (PIDS) - in which photobiomodulation therapy (PBMT) with low-power laser was used for edema reduction. This is an observational, descriptive, and retrospective work of a case report. The female patient, aged 73 years old, had undergone dermal filler six years before and complained of increased volume in the face region (glabellar region, labiomental sulcus, and nasolabial folds) and was submitted to ultrasound and anatomopathological analysis. PBMT using a low-power laser (660 nm and 808 nm, simultaneous irradiation, in contact, 2 J/point, 100 mW) proved to be effective for the non-invasive approach of late adverse reaction to dermal filler, such as PIDS, a common complication related to the use of dermal fillers.
