The optimal reconstruction size of nipple-areola complex following breast implant in breast cancer patients

A Comparison Study of Nipple-Areolar Complex Measurement: Light Detection and Ranging (LiDAR) Camera Versus Photometry

BACKGROUND

In breast surgery, achieving esthetic outcomes with symmetry is crucial. The nipple-areolar complex (NAC) plays a significant role in breast characteristic measurement. Various technologies have advanced measurement techniques, and light detection and ranging (LiDAR) technology using three-dimensional scanning has been introduced in engineering. Increasing effort has been exerted to integrate such technologies into the medical field. This study focused on measuring NAC using a LiDAR camera, comparing it with traditional methods, and aimed to establish the clinical utility of LiDAR for obtaining favorable esthetic results.

METHODS

A total of 44 patients, who underwent breast reconstruction surgery, and 65 NACs were enrolled. Measurements were taken (areolar width [AW], nipple width [NW] and nipple projection [NP]) using traditional methods (ruler and photometry) and LiDAR camera. To assess correlations and explore clinical implications, patient demographics and measurement values were collected.

RESULTS

NAC measurements using a periscope and LiDAR methods were compared and correlated. LiDAR measurement accuracy was found to be high, with values above 95% for AW, NW and NP. Significant positive correlations were observed between measurements obtained through both methods for all parameters. When comparing body mass index, breast volume with AW and NW with NP, significant correlations were observed. These findings demonstrate the reliability and utility of LiDAR-based measurements in NAC profile assessment and provide valuable insights into the relationship between patient demographics and NAC parameters.

CONCLUSIONS

LiDAR-based measurements are effective and can replace classical methods in NAC anthropometry, contributing to consistent and favorable esthetic outcomes in breast surgery.

Guiding Nipple-Areola Complex Reconstruction: Literature Review and Proposal of a New Decision-Making Algorithm

BACKGROUND

Nipple-areola complex reconstruction (NAR) most commonly represents the finishing touch to breast reconstruction (BR). Nipple presence is particularly relevant to the patient's psyche, beyond any shadow of doubt. Many reconstructive options have been described in time. Surgery is easy, but final result is often disappointing on the long run.

METHODS

The goal of this manuscript is to analyze and classify knowledge concerning NAR techniques and the factors that influence success, and then to elaborate a practical evidence-based algorithm. Out of the 3136 available articles as of August 8th, 2020, we selected 172 manuscripts that met inclusion criteria, which we subdivided into 5 main topics of discussion, being the various NAR techniques; patient factors (including patient selection, timing and ideal position); dressings; potential complications and finally, outcomes/patient satisfaction.

RESULTS

We found 92 articles describing NAR techniques, 41 addressing patient factors (out of which 17 discussed patient selection, 14 described ideal NAC location, 10 described appropriate timing), 10 comparing dressings, 7 studying NAR complications, and 22 addressing outcomes and patient satisfaction. We elaborated a comprehensive decision-making algorithm to help narrow down the choice among NAR techniques, and choose the correct strategy according to the various scenarios, and particularly the BR technique and skin envelope.

CONCLUSIONS

No single NAR technique provides definitive results, which is why we believe there is no "end-all be-all solution". NAR must be approached as a case-by-case situation. Furthermore, despite NAR being such a widely discussed topic in scientific literature, we still found a lack of clinical trials to allow for more thorough recommendations to be elaborated.

LEVEL OF EVIDENCE III

This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable. This excludes Review Articles, Book Reviews, and manuscripts that concern Basic Science, Animal Studies, Cadaver Studies, and Experimental Studies.

Patient-reported outcomes for nipple reconstruction: Review of literature

BACKGROUND

There is currently no validated patient-reported outcome measure (PROM) that is specific to nipple-areola complex (NAC) reconstruction. This paper evaluates all patient-reported outcomes for NAC reconstruction in the literature.

METHODS

Systematic literature searches of The Cochrane Central Register of Controlled Trials, MEDLINE and World Health Organization International Clinical Trials Registry Platform were conducted to identify all primary studies with patient-reported outcomes for NAC reconstruction. The primary outcome measures were patient satisfaction rates for appearance and symmetry of NAC reconstruction.

RESULTS

Fifty-nine papers were included in this review. Reported patient satisfaction was generally high, with the pooled average satisfaction rate for appearance being 81.9% and symmetry 80.3%. 89.5% of respondents would do it again and 94.8% would recommend it to others. There is no standardised or validated PROM specific to NAC reconstruction and this contributes to a lack of conclusive findings from studies in this area.

CONCLUSION

There is a need for a validated PROM that is specific to NAC reconstruction, in order to serve as a standardised outcome assessment to guide further research and improve patient care.
