Introduction:

The correction of the arcuate chest requires knowledge of the angle and sternal cut site. The objective of this work is to show the utility of the chest tomography for planning the correction.

Case report:

Male 15 years old, arcuate chest from birth. The tomography identified curvature, angle and distance to the correction site. These measurements were used during operation.

Conclusion:

The preoperative tomography allowed to measure the site, angle and depth of the sternal cut, parameters that were used during the operation, allowing for adequate correction in our patient.
