Importance:
Silastic implants are popular for cosmetic cheek augmentation. We describe the computed tomographic (CT) and magnetic resonance imaging (MRI) findings in 5 cases (4 patients) with penetration of the medial aspect of Silastic cheek implants through the anterior maxillary sinus wall.
Observations:
Three cases demonstrated associated sinus mucosal thickening, and 3 cases demonstrated infection surrounding the implant. In 3 cases, the implants migrated into the maxillary sinus, and in 1 case the implant also eroded through the nasoantral wall and extended into the nasal cavity.
Conclusions And Relevance:
Maxillary sinus penetration is a potential complication of Silastic cheek implants. The extent of this complication can be characterized by CT and MRI.
