Area of Science:

  • Medical Technology
  • Plastic Surgery
  • Biomedical Engineering

Background:

  • Achieving aesthetic symmetry is paramount in breast surgery, with the nipple-areolar complex (NAC) being a key factor in breast measurements.
  • Traditional measurement methods for the NAC exist, but advancements in technology, such as Light Detection and Ranging (LiDAR), offer new possibilities.

Purpose of the Study:

  • To measure the nipple-areolar complex (NAC) using LiDAR technology.
  • To compare LiDAR measurements with traditional methods (ruler and photometry).
  • To establish the clinical utility of LiDAR for enhancing aesthetic results in breast surgery.

Main Methods:

  • 44 patients undergoing breast reconstruction surgery were enrolled, with 65 NACs measured.
  • Measurements included areolar width (AW), nipple width (NW), and nipple projection (NP) using both traditional tools and a LiDAR camera.
  • Patient demographics and measurement data were collected to explore correlations and clinical implications.

Main Results:

  • LiDAR demonstrated high measurement accuracy (above 95%) for AW, NW, and NP compared to periscope/traditional methods.
  • Significant positive correlations were found between LiDAR and traditional measurements for all NAC parameters.
  • Correlations were also observed between body mass index, breast volume, and NAC parameters (AW, NW, NP).

Conclusions:

  • LiDAR-based measurements are effective and can replace classical methods for NAC anthropometry.
  • This technology contributes to achieving consistent and favorable aesthetic outcomes in breast surgery.
  • LiDAR provides reliable NAC profile assessment and insights into demographic influences.
