Summary
Breast skin sensitivity varies, with the superior quadrant being most sensitive and the nipple least sensitive. Larger breast size and ptosis significantly reduce breast sensation.
Area of Science:
- Medical Science
- Human Physiology
- Dermatology
Background:
- Breast sensation is crucial for various physiological functions.
- Understanding normal breast sensitivity and factors influencing it is important for clinical assessment.
Purpose of the Study:
- To establish normal values for breast cutaneous sensibility in healthy women.
- To investigate the impact of breast size and ptosis on breast sensation.
- To evaluate the efficacy of the Semmes-Weinstein monofilament test for breast sensation assessment.
Main Methods:
- A cohort of 150 healthy women participated in the study.
- Cutaneous pressure thresholds were measured bilaterally using Semmes-Weinstein monofilaments.
- Sensation was assessed in six distinct breast areas, including the nipple and areola.
Main Results:
- The superior breast quadrant exhibited the highest sensitivity, followed by the areola, with the nipple being the least sensitive.
- Increased breast size and ptosis were significantly correlated with decreased cutaneous sensibility across all tested areas.
- Previous pregnancy was associated with reduced nipple sensitivity.
Conclusions:
- Breast size and ptosis are significant factors affecting breast sensation.
- The Semmes-Weinstein test is a reliable method for evaluating breast tactile sensation.
- Findings provide normative data for breast sensitivity assessment.
