Summary
A novel technique using triangular advancement flaps effectively corrects congenital constriction ring syndrome (CCRS) deformities. This method offers a versatile and aesthetically pleasing solution for limb contour restoration.
Area of Science:
- Plastic Surgery
- Congenital Malformations
- Limb Deformities
Background:
- Congenital constriction ring syndrome (CCRS) presents a diverse range of clinical manifestations.
- Current surgical correction involves excision and Z- or W-plasties, with concurrent soft tissue correction for "sandglass" deformities.
Purpose of the Study:
- To introduce and evaluate a new surgical technique using triangular advancement flaps for correcting CCRS limb deformities.
- To assess the efficacy and aesthetic outcomes of this novel approach.
Main Methods:
- A technique utilizing triangular advancement flaps, placed proximally or distally to the constriction ring based on limb circumference, was employed.
- The technique was applied to eight patients with upper or lower limb involvement in CCRS.
Main Results:
- All eight patients achieved a normal extremity contour, with complete resolution of the constriction ring deformity.
- A mean follow-up of 43 months demonstrated aesthetically acceptable scarring and no recurrence of the deformity.
Conclusions:
- Triangular advancement flaps provide a versatile and effective method for correcting CCRS limb contour deformities.
- The technique yields favorable aesthetic results and a low recurrence rate.
