这个问题恐怕可以问倒很多整形的医师。如果细问的话,还可以问:乳头、乳晕和乳房的上下内外侧那个部份感觉会改变?会恢复吗?如果会,那要多久才会恢复?
虽然以前医师凭著经验,和问病人所得,有了一个模糊的答案,但并有没任何数据可以佐证。试想,若是医师帮病人隆完乳后,去摸病人的乳房,问她感觉如何?恐怕病人不愿意做这种「实验」
美国田纳西州的Nashville医院,使用一种仪器叫the Pressure Specified Sensory Device (Sensory Management Systems, LLC, Baltimore, Md.) 去测量病人隆乳后的乳房、乳晕及乳头感觉变化,得到了以下结论

Abstract
Background: Studies of alterations in breast sensibility after augmentation mammaplasty have produced conflicting results. Such discrepancies may be attributed to unsophisticated measuring devices used in earlier studies leading to less accurate measurements and to the comparison of results to different surgical techniques. The primary purpose of our study was to conduct a prospective clinical trial to quantify specific sensory outcomes before and after submuscular breast augmentation.
Methods: Preoperative and postoperative questionnaires were used to assess patients’ subjective observations on breast sensation. Quantitative data were collected using a very accurate device, the Pressure-Specified Sensory Device, to assess objective breast sensation. Thirty-three micromastia patients underwent quantitative measurements preoperatively (baseline), at 2 to 4 weeks and 6 months postoperatively to assess breast sensitivity.
Results: The quantitative data showed similar patterns of sensory change between both the periareolar and the inframammary surgical approach over time. The inferior region was the only region that showed a diminished sensitivity threshold of 9.5 +/- 2.9 gm/mm2 for the inframammary incision, a significantly poorer average than the periareolar incision of 1.7 +/- 0.6 gm/mm2 with p = 0.008 at 6 months. Older patients had significantly higher thresholds of sensitivity compared with younger patients (p < 0.02).
Conclusions: Our study suggests that the periareolar incision may produce less sensory loss in the lower pole of the breast when compared with the inframammary incision. The outcome of this study provides both the surgeon and the patient with concrete information regarding mammary sensation after augmentation mammaplasty and leads to a better informed-consent process.
这二张图是显示手术后随着时间,乳房的静态及动态感觉变化。点愈高,表示感觉愈差。由此我们可以看出二点重要结论:
1. 随着时间,术后六个月,乳房的感觉渐渐恢复。但是除了乳房外侧及乳头这二处有完全回复(指静态感觉),其它的部位和术前比较还是比较差。
2.乳房下半部的感觉恢复最差,而且以伤口在乳房下缘的手术方法在这二处的感觉恢复最差。
要注意的是本文只比较乳晕旁和乳房下切口对感觉的影响,并没有从腋下切口的研究。
