Summary

Textured breast implants showed no significant difference in malposition compared to smooth implants. However, using a polydioxanone (PDO) support matrix with smooth implants significantly reduced scar malposition in breast augmentation.

Background:

Textured breast implants are utilized in aesthetic surgery to reduce implant malposition.
A recent analysis indicated similar malposition rates between smooth and micro-textured breast implants.
The prophylactic use of a polydioxanone (PDO) internal support matrix was explored to enhance pocket control and prevent scar malposition.

Purpose of the Study:

To evaluate the efficacy of a polydioxanone (PDO) internal support matrix in preventing scar malposition during breast augmentation.
To compare implant-related complication and scar malposition rates among smooth implants, micro-textured implants, and smooth implants with PDO support.

Main Methods:

A cohort of 200 patients undergoing silicone gel primary breast augmentation by a single surgeon was analyzed.
Patients were divided into three groups: smooth implants alone, micro-textured implants, and smooth implants with a PDO internal support matrix.
Implant-related complications and scar malposition were recorded and compared across the groups.

Main Results:

No statistically significant difference in implant-related complication rates was observed between smooth and textured implants.
Scar malposition rates did not significantly differ between smooth and textured implant groups.
The group receiving smooth implants with a prophylactic PDO internal support matrix demonstrated the lowest scar malposition rate (4.48%), which was significantly lower than the smooth implant alone group (P=0.03).

Conclusions:

Micro-textured implants showed a trend towards decreased scar malposition, though not statistically significant.
Prophylactic use of a PDO internal support matrix in silicone gel breast augmentation is safe.
The PDO internal support matrix significantly reduced scar malposition rates in breast augmentation procedures.
