Summary

This study modified the Onen technique for pectus carinatum repair using a vertical incision. This modification allows seamless conversion to the Ravitch method if a pectus bar is unsuitable, improving surgical flexibility.

Area of Science:

Thoracic surgery
Pediatric surgery
Surgical techniques

Background:

Pectus carinatum repair often involves the Onen or Ravitch methods.
The Onen method typically uses a transverse incision.
Challenges arise when a pectus bar cannot be placed, potentially requiring additional incisions.

Observation:

A modified Onen technique was developed utilizing a vertical incision.
This approach was successfully applied to a 16-year-old male patient.
The patient presented with a mixed-type pectus carinatum deformity.

Findings:

The vertical incision in the modified Onen technique facilitates conversion to the Ravitch method.
This conversion can be achieved by simply elongating the existing incision.
No additional incision was necessary for the conversion in this case.

Implications:

This modification enhances surgical adaptability in pectus carinatum repair.
It offers a more efficient approach when pectus bar placement is not feasible.
The modified technique may reduce operative time and patient morbidity.
