Intraoperative Evaluation of Textured Anatomical Implant Rotation: A Prospective Study.

Abstract

Textured implants were developed with the goal of reducing rates of capsular contracture and preventing implant malposition (eg, malrotation). Recent evidence has questioned whether textured implants are as resistant to malrotation as previously reported. Women presenting to a single health care system for removal of textured implants were prospectively enrolled in the study from September of 2019 to July of 2022. Patients who underwent removal of an anatomical, textured implant in the operating room were included in the study; whereas those who did not undergo implant removal, or were found to have a smooth implant, or a round, textured implant, were excluded. The degree of implant rotation on removal of the implant was measured intraoperatively. Information regarding implant-specific factors, patient demographics, clinical factors, and operative characteristics, was collected. A total of 51 patients (80 implants) were included in the study; 45% of implants were malrotated (rotated >30 degrees), and the median degree of rotation was 30 degrees. Having more than one previous revision of the breast pocket was predictive of implant rotation (42 degrees) on multivariate linear regression analysis. Patients who presented with a complaint of "aesthetic dissatisfaction" had 2.89 increased odds of having an implant rotated greater than 30 degrees. The authors' study found a high rate of malrotation of textured shaped implants on explantation. Risk, III.
