Abstract
Background
Reoperation after primary breast augmentation remains an important clinical issue.
Objective
The authors sought to evaluate incidence and causes of reoperation in patients who underwent primary augmentation.
Methods
This retrospective, noninterventional study conducted at 16 Canadian sites reviewed medical records and patient-completed questionnaires of women who underwent primary breast augmentation with smooth or textured Natrelle Inspira implants containing TruForm 1 or TruForm 2 gel. Patients were aged ≥22 years, received implants via inframammary fold incision, and returned for follow-up at 2 to 4 years.
Results
A total of 319 women received Inspira implants (smooth TruForm 2, n = 205; textured TruForm 2, n = 99; smooth or textured TruForm 1, n = 15). At follow-up, 30 women (9.4%) had undergone reoperation, including 19 (9.3%) in the smooth TruForm 2 subgroup and 9 (9.1%) in the textured TruForm 2 subgroup. The mean time to reoperation was 1.2 years; the risk rate for reoperation was 9.9% at 3 years. The most common reasons for reoperation were implant malposition (36.7%), capsular contracture (33.3%), and the patient’s request for a change in implant size or style (20.0%). Most women were very or somewhat satisfied with the initial surgery (89.3% overall; 90.7% smooth TruForm 2; 86.9% textured TruForm 2). Thirty-four women (10.7%) reported adverse events, including 20 (9.8%) in the smooth TruForm 2 subgroup and 14 (14.1%) in the textured TruForm 2 subgroup.
Conclusions
This analysis suggests that Natrelle Inspira TruForm 2 implants are safe when used in primary breast augmentation, resulting in low reoperation rates that are consistent with those for other breast implants.
