Refining silicone implant correction of pectus excavatum through computed tomography.

Silicone implant correction of pectus excavatum has yielded satisfactory results in asymptomatic patients. Problems have been encountered with accurate implant fabrication and fit due to the soft-tissue masking of actual sternal contours. We have employed computed tomography to reconstruct the pectus deformity to improve implant design and fit. Instability can be prevented with the reduced need for intraoperative manipulation as well.
