The Nipple Safety Test: How Surgeons Use “Fluorescence” to Prevent Complications in Breast Reduction Surgery
The Surgical Anxiety: The “Dusky” Nipple
At the very end of a breast reduction procedure, one of the most stressful moments for a plastic surgeon is seeing a “dusky” or blue-looking nipple-areola complex. This discoloration can indicate poor blood flow, which may lead to a “slough” or the death of the tissue.
Historically, the response was to apply dressings and hope for the best the following morning. However, researchers in La Jolla, California, pioneered a more scientific approach: the Intravenous Fluorescein Test.
What is the Fluorescein Test?
Fluorescein is a special dye (resorcinolphthalein) that has been used in medicine since 1881. When injected into the bloodstream, it travels through the vessels and into the skin.
How the Test Works During Surgery
- The Injection: Before the final stitches are placed, the surgeon injects a specific dose of fluorescein intravenously.
- The UV Light: Fifteen minutes later, the room is darkened, and the breast is examined under an ultraviolet (UV) light.
- The Glow: Healthy, viable skin will glow a bright chartreuse (yellow-green) color under the light.
- The Warning: Any areas that remain dark blue or do not glow are at high risk for tissue loss.
The Study: Saving the Nipple in Real-Time
In a series of 35 patients undergoing McKissock-type reductions, surgeons used this test to predict and avoid disasters.
- The Reassurance: In 31 patients, the tissue glowed perfectly, confirming that everything was healthy.
- The “False Alarm”: In one patient, the nipple looked blue to the eye, but the fluorescein test showed it was glowing. The surgeon left it alone, and the tissue survived perfectly.
- The Life-Saving Intervention: In another patient, the test revealed no glow. The surgeon opened the incision and found that the internal tissue “pedicle” was kinked and folded too tightly. After correcting the position, the nipple glowed, and the tissue was saved.
Why This Matters for Your Safety
While this specific test was pioneered in the early 1980s, the principle remains a cornerstone of modern plastic surgery: Objective Safety Monitoring.
Today, surgeons may use similar fluorescence technology (like ICG-Angiography) to check blood flow during complex reconstructions. This “safety check” allows your surgeon to:
- Predict tissue survival with high accuracy.
- Correct internal issues (like kinked blood vessels) while you are still in the operating room.
- Avoid the “disaster” of nipple tissue loss.
Conclusion
Your safety during a breast reduction isn’t left to “prayer and hope”. Advanced techniques like fluorescein testing give surgeons a “window” into your blood circulation, ensuring that your results are not only beautiful but also medically sound.

Frequently Asked Questions (FAQ)
Q: Is the fluorescein dye safe?
A: Yes, it has been used safely in ophthalmology and surgery for over a century. The body typically clears the dye within 24 hours.
Q: Does every surgeon use a UV light test?
A: Not every surgeon uses this specific test for every patient. However, most will use clinical signs (like “capillary refill”) or modern infrared imaging if they have any concerns about blood flow during your procedure.
Q: Can a “dusky” nipple still survive?
A: Yes. As the study showed, sometimes a nipple looks dusky due to temporary bruising or vein congestion, but is actually healthy. The fluorescein test helps the surgeon tell the difference.
