Breast Reduction Surgery Complication Rates

As you prepare for any type of surgery, it’s normal to start thinking about all the things that could potentially go wrong. After all, going under the knife (even for a procedure that’s safely performed thousands of times each day) is a big decision. 

In this guide, we’ll help put your mind at ease by diving into the breast reduction surgery complication rates. Breast reduction surgery has an excellent safety profile, with most patients experiencing smooth recoveries. But like any surgical procedure, it does carry some risk of complications. Here’s what you need to know. 

Breast Reduction Surgery Complication Rates

Different studies use varying parameters to measure the complication rates of breast reduction surgery, so the numbers vary widely. 

Here’s a breakdown of the breast reduction surgery complication rates in a recent study of 760 patients: 

These researchers found that the overall complication rate for breast reduction surgery was around 38%. This number may seem high, but more than 69% of those complications are minor wound issues that heal on their own without requiring antibiotics. 

If we exclude minor wound issues, the overall complication rate is closer to 15%, and the number of patients experiencing major complications is just 4%. 

Types of Complications

Minor Complications

Of the 34% of patients who experienced minor complications, here’s a breakdown of the types of complications reported after breast reduction surgery:

These numbers show that minor complications are common, but low-risk, temporary, and usually easy to manage. Most involve mild wound separation or delayed healing that does not require antibiotics, a well-known and expected outcome given the tension on incisions and the size of the surgical area. 

Seromas, which involve fluid buildup at the surgical site, occur in just 2% of patients. This is usually easy to address through drainage or simple monitoring. 

Major Complications

Here’s a similar breakdown for the patients who experienced major complications: 

Hematomas, collections of blood in the surgical site, occur in around 3% of patients and typically appear within the first 24 to 48 hours after surgery. They may require surgical drainage, but they are generally straightforward to treat when identified early. 

More serious issues like deep infections and tissue necrosis are much less frequent. Deep infections may require IV antibiotics or surgical intervention, while tissue necrosis (loss of a small area of skin or tissue) can prolong healing but is uncommon with modern techniques and careful postoperative care.

Breast Reduction Hospital Readmission Rates

Hospital readmission after breast reduction surgery is uncommon, with one study reporting a 1.2% readmission rate. When it does happen, readmission is usually linked to a complication that requires closer monitoring or minor treatment, rather than additional surgery. The most common reasons for readmission include issues such as hematoma, infection, or concerns about delayed wound healing. 

More Breast Reduction Safety Statistics

While the data above highlights all reported complications in one study of 760 patients, other studies have described rare instances (occurring in less than 1% of patients) of additional complications, including: 

• Pneumonia
• Sepsis
• Pulmonary embolism
• Deep vein thrombosis

These events are extremely uncommon in otherwise healthy breast reduction patients, and are more related to the general risks of any type of surgery, rather than specific issues unique to breast reduction. 

Factors Increasing the Risk of Breast Reduction Surgery Complications

Many of the studies evaluating breast reduction surgery complication rates also investigate risk factors that make a patient more likely to experience complications. Here’s an overview of some of those factors, and how they may potentially affect complication rates:

Age

Age over 65 is associated with a 1.5x higher risk, which reflects slower wound healing, reduced skin elasticity, or the presence of age-related medical conditions. Even so, many older adults undergo breast reduction safely when they are otherwise healthy.

Tobacco Use

Smoking increases complication risk by 1.7x, largely because nicotine restricts blood flow and interferes with oxygen delivery to healing tissues. This can lead to wound breakdown, infection, or (in severe cases) tissue necrosis. This is why surgeons often require patients to stop all nicotine use well before surgery.

BMI

Higher BMI is another risk factor, and is strongly linked to delayed wound healing, infection, seroma formation, and anesthesia-related challenges. This doesn’t mean patients with higher BMI cannot safely undergo breast reduction, but they require careful preoperative planning and counseling with an experienced plastic surgeon.

ASA Classification

Before surgery, the anesthesiologist gives each patient an ASA (American Society of Anesthesiologists) classification from I–VI, based on the patient’s health status. Patients with a higher rating often have underlying conditions like cardiac disease, diabetes, or lung issues, making anesthesia and healing more complex. 

Minimize Complication Rates with Harris Plastic Surgery

Overall, breast reduction surgery complication rates are low, and generally reflect the risk involved with any type of surgery. Even patients with risk factors can safely undergo breast reduction surgery, as long as they work closely with an experienced plastic surgeon who can provide the highest level of pre- and post-operative care.
