The relationship of human acellular dermal matrix thickness on complication rate and patient-reported outcomes in implant-based immediate breast reconstruction.

Abstract

Background\nAs it can be said that prosthetic breast reconstruction has been increased by the use of acellular dermal matrices (ADMs), ADMs are widely used in implant reconstruction. A large variety types of ADMs are now produced, but there is a paucity of data comparing the ADM products directly. We evaluated the effects of ADM thickness on complication rates and patient satisfaction after dual-plane subpectoral ADM-assisted implant breast reconstruction.\n\n\nMethods\nA retrospective study of patients who underwent immediate implant breast reconstruction using ADM was performed. We compared clinical course and postoperative outcomes for two ADM groups with different thicknesses [thin ADMs, 0.6-1.5 mm (group 1) vs. thick ADMs, 1.5-3.0 mm (group 2)] based on the incidence of complications and the duration of drainage. Patient satisfaction was also evaluated using the Breast Questionnaire (BREAST-Q), 6 months after surgery.\n\n\nResults\nA total of 51 patients were included in the study (group 1, n=21; group 2, n=30). Patient demographics were similar between the two groups, and no difference in postoperative complication rate (P>0.05) and Jackson-Pratt (JP) drainage durations (P>0.05). On regression analysis, ADM thickness was not an independent factor for any complication subtype. There were also no significant differences in BREAST-Q results, across all metrics, between the study groups.\n\n\nConclusions\nIn dual plane subpectoral implant placement breast reconstruction with an inferior ADM-sling, the thickness of ADM was not a factor in determining postoperative complications and patient satisfaction. Therefore, it is possible to select the thickness according to the surgeon s preference.
