The patient is an 11-year-old girl who has had chest wall deformity since childhood. Despite being diagnosed with Poland syndrome at the age of 6, she did not undergo any treatment. From the age of 10, her left mammary glands began to develop while the right one did not, resulting in progressively severe asymmetry of her chest wall.

The chest wall exhibits asymmetry with the left mammary glands developing normally, whereas the right side of the chest wall has a depression. This asymmetry is further characterized by a defect in the right pectoralis major, underdevelopment of the right mammary glands, and detachment of the third costal cartilage from the ribs on the right side.

Two bars were utilized in the Willine procedure to effectively correct the deformity. The surgery was successful, resulting in the elimination of the deformity and restoration of normal chest appearance.

Willine Procedure — An Integration of the Wung Procedure and the Wenlin Procedure

The Willine procedure is a comprehensive operation highly effective in treating a wide range of complex chest wall deformities. During the procedure, one side of the bar is used for performing the Wenlin procedure, while the other side is used for the Wung procedure. This allows for the simultaneous correction of both concave and convex deformities.

Poland syndrome, characterized by abnormalities confined to one side of the chest wall, can lead to the collapse or indentation of the affected chest wall. Thus, it can also be considered complex deformities that combines both indentation and relatively protruded regions, which makes it suitable for correction using the Willine procedure.
