Imaging of Malar Silastic Implant Complications

Facial cosmetic implants are utilized for definition enhancements in the malar, mandibular, and nasal regions. Though these implants are safe in the majority of patients, notable complications such as implant malpositioning may be seen. More rare but serious complications such as infection, abscess, and intrasinus migration may also occur, such as in this case reported on a 69-year-old female with a history of bilateral malar silicone implants. Imaging findings on this patient, whom initially presented with complaints of erythema and edema in the left malar region, were notable for edema and soft tissue signs of infection around a well-visualized crescent shaped maxillary implant. Penetration of the implant into the left maxillary sinus was also noted. Diagnostic imaging played a key role in determining the cause and severity of this patient’s condition. Thus, the case reported is with an aim to familiarize radiologists with identifying and interpreting the complications of malar cosmetic implants on diagnostic imaging.
