Background: Rippling and implant edge visibility after breast augmentation depends on several factors. Among the most relevant are breast soft tissue thickness, particularly the retroareolar mammary parenchyma, and implant profile. They were correlates to prevent these occurrences.
Methods: Thirty patients underwent breast augmentation through subfascial dissection involving the pectoralis, serratus, external oblique, and rectus abdominis fascias. The thickness of the retroareolar mammary parenchyma distributed patients into two groups. Group I: patients with thickness equal to or greater than 4.0 cm received high-profile 85% fill round implants. Group II: patients with thickness up to 3.9 cm received extra-high-profile 100% fill round implants. MRI was performed preoperatively and 5 years after augmentation to evaluate breast tissue changes and implant contouring.
Results: Seventeen patients with high-profile implants and thirteen patients with extra-high-profile implants had noticeable improvement of the breasts without the occurrence of rippling or implant edge visibility. A natural appearance of the breast, increased mammary cone, balanced upper and lower pole contouring was maintained at 5 years postoperatively. MRI performed 5 years after breast augmentation validated patient clinical outcomes not evidencing implant deformities, or soft tissue thinning, parenchymal atrophy or chest wall deformities.
Conclusions: The adequate correlation between retroareolar mammary parenchyma thickness with high-profile 85% fill and extra-high-profile 100% fill textured round implants was of utmost importance in preventing rippling and implant edge visibility. The wide fascial support, width of the implant smaller than the breast diameter, and soft cohesive gel-filled implants were co-adjuvant factors in preventing rippling and implant edge visibility.
