MIMEDX PURION® Processed Placental Allografts Proved Safer Than Autologous Tissue, Reducing Infection, Scarring and Reoperation Rates
The retrospective propensity score-matched case-control study demonstrated that PURION® processed dHACM placental allografts were associated with a statistically significant lower risk for infection, poor scar cosmesis, scar revision, and additional operation at the index site, when compared to traditional methods of incisional repair. The findings indicate that placental allografts may be a viable alternative to autologous tissue-based reconstruction, including flaps and full-thickness skin grafts (FTSG), particularly in an aging population undergoing numerous Mohs procedures in moderate to high-risk areas of the face, head, neck, and dorsal hand.
“The impressive results of this study show the utility and good patient outcomes when using MIMEDX’s EPIFIX® in patients where a more invasive surgical alternative is not a viable option,” said
Mohs micrographic surgery is considered the most effective technique for treating many basal and squamous cell carcinomas, the two most common types of non-melanoma skin cancer (NMSC). With the incidence of NMSC increasing rapidly in people over 65, Mohs has become a common procedure to remove these cutaneous malignancies. In some cases, lesions occur multiple times in a localized region and repeat surgery to remove them impacts quality and availability of nearby autologous tissue, thereby impacting the aesthetic and functional success of graft or flap procedures. To complicate matters, tumors among the elderly are often more invasive, and obtaining cancer-free margins can result in significant tissue loss, which further increases the need to consider alternative tissue sources.
“When there are limited options for surgical reconstruction due to unavoidable patient or defect location considerations, patients may experience longer recovery times, unpredictable scarring, and emotional distress,” said
The retrospective, case-controlled study patient population (n = 286) included 143 propensity score-matched pairs undergoing MMS for a basal or squamous cell carcinoma on the face, head, neck, or dorsal hands with same-day reconstruction using either autologous tissue or dHACM placental allograft, between
Patients who received placental allografts were 12 times less likely to have a post-surgical infection or require additional surgery, and 19 times less likely to have unacceptable scarring. A significantly greater proportion of patients in the placental allograft group (97.9%) experienced zero postoperative complications compared to patients undergoing autologous tissue-based repairs (71.3%). Placental allograft cases developed less infection than their flap and FTSG counterparts, and no instances of bleeding, dehiscence, non-healing wounds, scar revision, additional operation at the index site, or poor scar cosmesis were observed.
These findings support the potential for use of the Company’s PURION® processed dHACM placental allografts as an alternative to existing methods for reconstructive repair in Mohs procedures, particularly in older patients with moderate to high-risk defects.
