Abstract:
Background:In 716 Mongolian patients who had breast augmentation surgery at Perfect
Clinic during 18 years. The purpose of this study evaluates Mongolians predictors of early and late
outcome after primary breast augmentation surgery.
Aims of study:In this study, we aimed to clarify predictors of early and late outcome after breast
augmentation surgery.
Methods:We selected patients who underwent breast augmentation implant surgery between
1999 and 2017. Development of hematoma was chosen for measure of early outcome and
capsule contracture was chosen for measure of late outcome. Multivariable Cox proportional
hazard regression and Kaplan-Meier estimations were used to clarify independent relationship
between possible predictors and outcomes.
Results:A total of 716 patients were chosen and mean age was 32±7 years old. Hematoma was
occurred in 43 patients (6%) and median time to hematoma was 3 days (IQR 1; 7).). According
to the univariable analysis, every 1 year experience was associated with 9% decreased risk of
hematoma development. (HR=0.91, 95% CI 0.84-0.99, p<0.05). Finally, Kaplan-Meier estimation
was showed that hematoma free survival is higher in more experienced years and patients who
had subpectoral muscle.(log rank p<0.01 and p<0.001, respectively).
Capsule contracture was occurred in 38 patients (5.3%) and median time to capsule contracture
was 10 months (IQR 3; 27). According to the univariable analysis, every 1 year increase of surgical
experience is related to 9% decreased risk of capsule contracture (HR=0.81, 95% CI 0.75-0.88,
p<0.001), and more textured implant type is associated with less capsule contracture (HR=0.47,
95% CI 0.34-0.66, p<0.001).
Multivariable hazard regression was revealed that implant type (HR=0.55, 95% 0.33-0.90, p<0.05)
and surgical time (HR=1.00, 95% CI 1.00-1.01, p<0.001) were independently associated with
capsule contracture after breast augmentation surgery (Table 4). Kaplan-Meier estimation was
determined that capsule contracture free survival is higher in more experienced years and
patients who had more textured implant and subpectoral muscle implant (log rank p<0.001,
p<0.001 and p<0.001, respectively).
Conclusions:For breast augmentation surgery, implant type is independent predictor of capsule
contracture and surgical experience is predictor for both hematoma and capsule contracture.
Therefore, above mentioned predictors should be considered to prevent complications related
to breast augmentation implant surgery.
