Silicone gel implants are regarded as esthetically superior to saline implants, offering a more natural consistency. They are also considered less susceptible to rippling. However, objective measurements and patient-reported outcome studies are lacking. Similarly, minimal data are available quantitating animation deformity.
A 3-year prospective study was undertaken among 223 women undergoing primary subpectoral breast augmentation using either saline (n = 145) or silicone gel (n = 78) implants. Photographs obtained included frontal views with the patient flexing the pectoral muscles. Images were matched, and vertical differences in nipple position were measured. Breast implants were evaluated using high-resolution ultrasound to detect any ripples or folds at least 3 months after surgery. Outcome surveys were administered. Statistical analysis included the χ test, point-biserial correlations, and a power analysis.
Respondents reported visible rippling in 18% of women and palpable rippling in 32% of patients, with no significant difference between women treated with saline and silicone gel implants. Ripples were detected on ultrasound scans in 24% of women with saline implants and in 27% of women with silicone gel implants (difference not significant). Ripples were more common in women with lower body mass indices. Fifty percent of patients demonstrated nipple displacement <1 cm on animation. Nipple displacement occurred either up or down with equal frequency and a mean overall nipple displacement of zero.
Saline and silicone breast implants produce similar degrees of rippling, as determined on outcome surveys and ultrasound examination. Animation deformities tend to be minor and well-tolerated.
硅胶植入物在美学上被认为优于盐水植入物，具有更自然的质地。它们也被认为更不易出现波纹。然而，缺乏客观测量和患者报告的结局研究。同样，定量动态畸形的数据也很少。
对223例行初次胸大肌下隆乳术的女性进行了一项为期3年的前瞻性研究，其中145例使用盐水植入物，78例使用硅胶植入物。拍摄的照片包括患者收缩胸肌时的正面视图。对图像进行匹配，并测量乳头位置的垂直差异。术后至少3个月使用高分辨率超声评估乳房植入物，以检测是否有任何波纹或褶皱。进行结局调查。统计分析包括χ检验、点二列相关分析和效能分析。
受访者报告18%的女性有可见波纹，32%的患者有可触及波纹，盐水植入物和硅胶植入物治疗的女性之间无显著差异。盐水植入物女性中24%在超声扫描中检测到波纹，硅胶植入物女性中27%检测到波纹（差异不显著）。波纹在体重指数较低的女性中更常见。50%的患者在动态时乳头移位<1厘米。乳头移位向上或向下的频率相同，总体平均乳头移位为零。
根据结局调查和超声检查，盐水和硅胶乳房植入物产生的波纹程度相似。动态畸形往往较小且耐受性良好。
