"Mammacompliance": an objective technique for measuring capsular fibrosis

Area of Science:

• Biomedical Engineering
• Plastic Surgery
• Medical Device Development

Background:

• Current assessment of silicone implant outcomes relies on Baker's classification, a subjective clinical method.
• Objective, quantifiable measurements are crucial for scientific rigor in evaluating breast augmentation and reconstruction.
• Existing methods lack the precision needed for detailed postoperative monitoring.

Purpose of the Study:

• To develop and validate an objective measurement for breast tissue compliance.
• To correlate objective measurements with subjective clinical assessments like Baker's classification.
• To provide a sensitive tool for assessing capsular contracture and monitoring treatment efficacy.

Main Methods:

• Adaptation of a breast compressibility caliper with integrated force transducer and distance measurement.
• Generation of force-distance graphs to analyze breast tissue response.
• Calculation of "mammacompliance" values from graph data, expressed in cm at a defined force.
• Examination of 68 augmented/reconstructed breasts and 59 normal breasts.

Main Results:

• A strong correlation was observed between mammacompliance values and Baker's classification.
• The objective method identified potential clinical misjudgments in subjective assessments.
• Mammacompliance demonstrated high sensitivity in assessing capsular contracture.
• The technique proved effective in controlling and monitoring postoperative development.

Conclusions:

• Mammacompliance offers an objective and sensitive method for assessing breast tissue characteristics post-surgery.
• This technique enhances the evaluation of capsular contracture compared to subjective methods.
• It serves as a valuable tool for monitoring patient recovery and therapeutic interventions.
