A Comparison of Ovine-Reinforced Hybrid Mesh (OviTex PRS) With Porcine Acellular Dermal Matrix (STRATTICE) in the Treatment of Advanced Breast Implant Capsular Contracture.

[BACKGROUND] Tissue reinforcement techniques with porcine acellular dermal matrices (ADMs) have been widely adopted as standard care in treating capsular contracture. However, the application of alternative xenograft or mesh materials has not been widely studied.

[OBJECTIVES] To examine the efficacy of OviTex PRS Reinforced Tissue Matrix (Resorbable) (TELA Bio, Malvern, PA), a hybrid ovine-reinforced mesh, in comparison with STRATTICE Reconstructive Tissue Matrix (Allergan, Irvine, CA), in patients with advanced capsular contracture.

[METHODS] A retrospective review was conducted on patients who underwent breast revision surgery for Baker Grade III or IV capsular contracture. Patient data were reviewed for outcomes, complications, cost, and postoperative incidence of recurrent capsular contracture after treatment with each specific mesh.

[RESULTS] Fifty-nine of 89 breasts (66.3%) were treated with OviTex and 30 (33.7%) were treated with STRATTICE. All patients experienced a reduction in Baker grades. In patients treated with OviTex, 96.6% ( = 57) of breasts had a postoperative Baker Grade I with the remaining 3.4% ( = 2) breasts presenting with a Baker Grade II. In comparison, 73.3% ( = 22), 23.3% ( = 7), and 3.3% ( = 1) of the STRATTICE cohort presented with Baker Grades I, II, and III, respectively. This demonstrated a statistically significant improvement in Baker grade capsular contracture in the OviTex cohort ( < .05) compared with STRATTICE. Average cost was $27.37/cm for STRATTICE compared with $22.28/cm for OviTex PRS.

[CONCLUSIONS] OviTex may be successfully utilized to treat capsular contracture. Patient outcomes may be superior to STRATTICE in recurrent capsular contracture, particularly when a previous ADM had been utilized. Cost data show improved savings with the use of OviTex compared with STRATTICE.
