Polydioxanone Monofilament Mesh: A Safety Net for Complex Breast Implant Revision Surgery

BACKGROUND: Breast revision surgeries are complex cases requiring greater pocket control than primary surgeries. Intraoperative techniques to maximize pocket integrity are crucial to achieving an aesthetic result in revisions with implants. OBJECTIVES: Uniform utilization of a polydioxanone (PDO) internal support matrix in a high volume of revision-augmentation cases has, to our knowledge, never before been described. METHODS: A high-volume (n = 104) single-surgeon experience followed patient outcomes in consecutive cases from September 2020 to March 2022. Included in this cohort were patients undergoing revision-augmentations with vertical or wise-pattern mastopexies (n = 74), revision-augmentation without mastopexies (n = 25), and revision without implant exchange (n = 5). Each case employed at least 1 sheet of PDO mesh, with a small set (n = 4) receiving 2 sheets. Patients were followed up (range, 3-19 months), with 3 months minimum follow-up to assess outcomes. RESULTS: The average length of follow-up was 8.8 months. Patients in this cohort had undergone an average of 1.6 prior breast surgeries (range, 1-7). A total 89.4% of patients received an increase in implant volume (average change, +165.2 Cc); 87.5% of patients had favourable aesthetic outcomes, and 12.5% of patients were reoperated on (including reoperations for complications and/or aesthetic reasons). There were 13 complications in the cohort, and no mesh-related complications. CONCLUSIONS: PDO mesh is a safe and effective method of increasing pocket control in breast revision. Supplemental soft-tissue support allowed greater implant volumes to be employed, yielding high rates of patient satisfaction with breast shape, scarring, and long-term aesthetics.
