Abstract
Silicone implants for augmentation rhinoplasty have been used by many surgeons over the past few decades. However, no clinical evaluation of the nasal bones beneath the silicone implant has been conducted to date. Between 2010 and 2012, we reviewed patients' facial computed tomography scans and finally selected 13 patients according to the exclusion criteria. To evaluate the extent of bone resorption, we measured the angle (theta) of the deformed portion. And we measured the thickness of nasal bones to evaluate the bony resorption.A total of 13 patients had some evidence of bone resorption or bony deformity on their computed tomography. An evaluation of the CT scan of the nasal bones showed deformity of the bones underneath the implant. The bones had lost the dome shaped convexity and showed flat configuration under the implant. The values of the angle (theta) ranged from 45to 75 degrees (mean 58.1 degree). The thickness of nasal bone showed statistically significant results at the tip of bony vault. This study has demonstrated of bone deformation beneath the silicone implants in humans.
Key Words: Rhinoplasty, Bone resorption, Silicones
