    Summary

    This study introduces a novel double-lumen mammary implant with an adjustable steroid concentration to manage augmentation mammaplasty outcomes. Higher steroid levels reduced capsular contracture, demonstrating the implant

    Area of Science:

    • Plastic Surgery
    • Biomaterials Science
    • Pharmacology

    Background:

    • Augmentation mammaplasty commonly involves mammary implants.
    • Capsular contracture is a frequent complication following breast augmentation.
    • Existing implants lack adjustable features for managing complications.

    Purpose of the Study:

    • To evaluate the efficacy of a novel double-lumen mammary implant with an adjustable injection valve.
    • To assess the impact of varying intraluminal steroid concentrations on complication rates.
    • To explore the potential for future implant modifications with antibiotics or other additives.

    Main Methods:

    • A custom-designed double-lumen mammary implant with an injection valve was utilized.
    • Steroid concentration (Solu-Medrol) was adjusted based on clinical response.
    • A retrospective study analyzed 311 breasts over a minimum 12-month follow-up period.

    Main Results:

    • Temporary capsular contracture rates decreased with increasing initial Solu-Medrol concentration.
    • Rates were 23.7% (no steroid), 17.6% (5 mg/40 ml), and 7.8% (10 mg/40 ml).
    • The implant allows for dynamic adjustment of intraluminal contents.

    Conclusions:

    • The steroid-adjustable mammary implant effectively reduces capsular contracture rates.
    • The custom injection valve facilitates precise management of implant-related complications.
    • This implant design offers future potential for incorporating antibiotics and other protective agents.
