Background: In patients with panfacial fractures and distorted anatomic landmarks of zygomatic and orbital complex, there is a risk of zygomaticomaxillary complex (ZMC) malpositioning even with the best efforts for surgical repair. This results in increased number of additional procedures to achieve accurate positioning. Methods: We describe the usage of intraoperative C-arm cone-beam computed tomographic (CT) scan for ZMC malpositioning in a representative patient with panfacial fractures. Results: We have successfully used intraoperative CT scan for ZMC malpositioning in 3 patients. The representative patient had ZMC malposition after the initial attempt of surgical repair without any intraoperative imaging. On using intraoperative CT scan during the next attempt, we were able to reposition the ZMC accurately. Conclusions: Intraoperative CT scan might improve the accuracy of ZMC positioning and decrease the chances of potential additional surgeries. In patients with distorted anatomical landmarks and panfacial fractures, it can be especially helpful toward correcting ZMC malposition.

Summary: Liquid silicone is inexpensive, minimally antigenic, and likely noncarcinogenic. Its simplicity of use has made it popular as a soft-tissue filler in some parts of the world for patients seeking rapid soft-tissue augmentation of the face, breast, and buttocks. However, multiple reports describe the complications of silicone injections such as cellulitis, abscess, ulceration, and foreign body migration. We present an unusual complication of granulomatous reaction secondary to silicone injection for buttock augmentation, with a literature review of this entity and treatment options. Our patient was a 54-year-old woman who underwent bilateral buttock augmentation in the Dominican Republic using percutaneous injection of liquid silicone. She presented to our facility 1 year after this procedure with pain and inflammation of both buttocks. She was diagnosed with multiple silicone granulomas. Her symptoms completely resolved with a 3-week course of minocycline. Granulomatous reactions to silicone may occur months to years after the silicone injection. The incidence of such complications may be increased when nonmedical-grade silicone is used, and hence, when these procedures are performed in developing countries. Tetracycline antibiotics, especially minocycline, may be used to achieve sustained remission.
