Commentary on: Complications After Facial Injections With Permanent Fillers: Important Limitations and Considerations of MRI Evaluation.

Abstract

In “Complications After Facial Injections With Permanent Fillers: Important Limitations and Considerations of MRI Evaluation,” the authors propose the use of magnetic resonance imaging (MRI) as an investigative tool in the assessment of delayed-onset complications subsequent to injections of permanent fillers.1 Utilization of this investigative imaging tool is proposed to be helpful in assessing filler-related complications where it is difficult to clinically assess the nature and extent of the complication. The study included 32 patients who underwent a pretreatment MRI evaluation of post–facial filler injection complications. After 13 of 120 site-specific assessments were excluded due to poor image quality, a total of 107 site-specific clinicoradiologic evaluations were obtained. Clinicoradiologic level of agreement was assessed as strong for depots without complications and noninflammatory nodules (85%), as moderate for abscesses (60%), as fair for low-grade inflammations (32%), and as slight for migrations (9%). In 14% of the cases, results from pretreatment MRI were helpful in the treatment decision making. I commend the authors for undertaking this study to evaluate the role of MRI in the treatment of post–permanent filler complications. Such studies do have a role in …
