%X BACKGROUND: A congenital constriction band (CCB) is a relatively common anomaly among limb malformations. However, the number of cases treated at a given center is limited and differences in techniques used by surgeons at each facility have a significant impact on the treatment outcomes. Several surgical methods have been reported, but a standard technique that yields consistent satisfactory results is still needed. Here, we introduce a novel technique for the treatment of CCB syndrome that uses a combination of wave-like skin incision and Z-axis Z-plasty.
METHODS: A wave-like incision was used for skin incision with the goals of achieving an accordion effect and a less noticeable post-operative scar. After the fibrous constriction band was completely excised, a Z-plasty of sufficient size in the Z-axis direction was performed on the dermis-inclusive adipose tissue. For over 10 years, this technique was applied to 11 sites in 6 patients. A retrospective study of the characteristics of these cases was performed, including age at surgery, gender, type of deformity, degree of constriction, types of examination, number of surgeries, and post-operative outcomes.
RESULTS: In all patients, a normal contour of the limbs was achieved and the hourglass-like deformity caused by the constriction band was satisfactorily improved. No additional corrective surgeries were needed, there was no abnormal growth of the treated limbs, and scarring was aesthetically acceptable in all cases.
CONCLUSIONS: The novel technique described here uses deep subcutaneous fat to correct the hourglass-like deformity and restores a normal limb contour, while the wave-like skin incision minimizes post-operative scarring.
