Using Clinical Measurements to Predict Breast Skin Necrosis: A Quantitative Analysis

Area of Science:

• Plastic Surgery
• Oncology
• Reconstructive Surgery

Background:

• Mastectomy skin flap necrosis can lead to complications like poor healing, reoperation, and undesirable aesthetic results.
• Delayed recovery from necrosis can impede adjuvant oncologic treatment regimens.
• Identifying risk factors for necrosis is crucial for improving post-mastectomy outcomes.

Purpose of the Study:

• To investigate breast surface area as a risk factor for mastectomy skin flap necrosis.
• To identify specific preoperative clinical measurements that can predict necrosis.
• To enhance the prediction and management of post-mastectomy complications.

Main Methods:

• Retrospective analysis of 926 immediate breast reconstructions.
• Inclusion of patients undergoing mastectomy and reconstruction between 2011 and 2021.
• Utilized preoperative measurements (nipple-notch distance, nipple-inframammary fold distance, chest width, breast circumference, breast height) to estimate breast surface area.

Main Results:

• Increased breast surface area (approximated as cone or half ellipsoid) was a significant risk factor for mastectomy skin flap necrosis (P = 0.027 and P = 0.022).
• Preoperative measurements including nipple-notch distance, nipple-inframammary fold distance, chest width, breast circumference, and breast height were significant predictors of necrosis (P < 0.05).
• Specific cutoff values for these measurements were identified that increase the incidence of necrosis.

Conclusions:

• Larger breast surface area is an independent risk factor for developing breast skin necrosis post-mastectomy.
• Preoperative breast measurements serve as valuable tools for predicting necrosis in patients undergoing mastectomy.
• These findings can guide surgical planning and patient counseling to mitigate necrosis risk.
