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 (θ) 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 (θ) 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.
