Comparison of Different Acellular Dermal Matrix in Breast Reconstruction: A Skin-to-Skin Study.

BACKGROUND

Since the early 2000s, acellular dermal matrix has been a popular adjunct to prepectoral breast reconstruction to enhance outcomes.

OBJECTIVES

The aim of this study was to investigate the differences in the postoperative course of 2 standard acellular dermal matrix products, AlloDerm SELECT Ready To Use and DermACELL.

METHODS

A prospective, patient-blind study of patients undergoing bilateral nipple and/or skin-sparing mastectomies with either tissue expander or silicone implant insertion between 2019 and 2022 were selected for this study. The study design used patients as their own controls between 2 products randomly assigned to the left or right breast. Outcomes between the products included average time for drain removal, infection rate, seroma rate, and incorporation rates.

RESULTS

The prospective clinical data of 55 patients (110 breasts) were recorded for 90 days. There were no significant differences between drain removal time, average drain output, or seroma aspiration amount. A higher percentage of seromas was recorded in the breasts with AlloDerm (30.91%) compared with breasts containing DermACELL (14.55%, P < .05), and a statistically significant difference between the incorporation rates of AlloDerm (93.4%) and DermACELL (99.8%, P < .05) was observed.

CONCLUSIONS

Irrespective of patient demographic disparities, both products had a 94.55% success rate for reconstruction outcomes. AlloDerm was determined to have a higher incidence of seromas as a postoperative complication and a trend to lower incorporation.
