Master 2024: 33 patients (24 asymptomatic, 9 with edema concerns), HA visible on MRI in all; 12 not injected for more than 5 years; longevity up to about 15 years; small, selected cohort. Mariluis 2026: persistent chin pressure 2 years after high-G-prime HA; two high-frequency ultrasounds showed only a small supraperiosteal bolus; MRI showed diffuse HA in subcutaneous fat; 150 IU targeted hyaluronidase gave complete relief, confirmed on follow-up MRI. El Feghaly and Tawa 2026: bilateral upper eyelid edema with unremarkable labs and orbital MRI; blepharoplasty histology showed HA; temple filler 2 years earlier recalled after surgery. Elective use of hyaluronidase to dissolve filler is off-label.\n\nThe voices in this episode were generated with AI (ElevenLabs).
