Summary
A double Z-plasty can enhance rhombic flap mobility when unexpected tissue restriction occurs. This technique increases flap length, aiding transposition in challenging reconstructive surgery cases.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Surgical Techniques
Background:
- Rhombic flaps may encounter unexpected transposition difficulties due to prior surgery or improper orientation.
- Skin tension can impede the smooth movement of rhombic flaps into recipient sites.
Purpose of the Study:
- To demonstrate how a double Z-plasty can overcome restricted rhombic flap movement.
- To illustrate the use of a double Z-plasty for increasing tissue length and flap mobility.
Main Methods:
- A double Z-plasty was integrated into the rhombic flap design for one patient.
- The biomechanics of the modified rhombic flap were analyzed.
- The technique was applied to a total of four patients.
Main Results:
- Incorporating a double Z-plasty successfully increased rhombic flap mobility.
- The enhanced flap movement was predictable across all four treated patients.
Conclusions:
- A double Z-plasty is a valuable adjunct for improving rhombic flap mobility.
- This technique addresses uncommon situations involving restricted flap transposition.
