Injection dome leakage in tissue expanders can cause saline solution loss, especially under body weight pressure. While leakage is slow, it

Area of Science:

  • Plastic Surgery
  • Biomaterials Science

Background:

  • Tissue expanders are crucial in reconstructive surgery.
  • Understanding potential complications is vital for patient outcomes.

Purpose of the Study:

  • To investigate injection dome leakage as a cause of saline solution loss in tissue expanders.
  • To quantify leakage pressures and volumes under various conditions.

Main Methods:

  • Analysis of 22 consecutively removed tissue expanders.
  • Measurement of injection dome leakage pressure (average 32 mmHg).
  • Simulation of intraluminal pressures (up to 90 mmHg) due to body weight.

Main Results:

  • Injection dome leakage identified as the cause of saline solution disappearance.

  • Leakage up to 50% of injected volume observed in some cases.
  • Slow leakage flow rates measured at pressures of 25, 50, and 75 mmHg over 30 minutes.

    • Conclusions:

    • Injection dome leakage is a potential complication in tissue expanders, particularly under pressure.
    • Despite potential leakage, tissue expanders generally function reliably.
    • Awareness of this complication is important for managing patient expectations and outcomes.
