Effectiveness of SCAR-Q for assessment of incisional SCAR after implant-based reconstruction in breast cancer patients: Can it be a tool for incision selection?

Incisional scarring is a factor of cosmetic appearance evaluated after breast reconstruction, along with the shape, position, and size of the breast. This study aimed to examine the effect of the incision scar location on patient satisfaction after breast reconstruction. Using the Japanese version of the SCAR-Q, we assessed the scar appearance, symptoms and psychosocial effects. Plastic surgeons performed assessments using the Manchester Scar Scale. The patients were divided into two groups: those with scars on the margins of the breast (MB group) and those with scars in the breast area (IB group). The results revealed that patients in the MB group reported significantly higher satisfaction with the scar appearance and psychological impact than those in the IB group. However, assessments using the Manchester Scar Scale did not reveal any significant differences between the two groups. In conclusion, this study underscores the importance of patient-reported outcomes in the evaluation of scar satisfaction after breast reconstruction. Patients tend to prefer and have higher satisfaction with scars along the breast margin, which offers valuable insights into surgical decisions. Further studies with larger and more diverse sample sizes are required for validation.

Volume Prediction of Extended Latissimus Dorsi Musculocutaneous Flap for Breast Reconstruction Using a Computed Tomography Volume-Rendering Technique with an X-ray Contrast Thread Marking.

BACKGROUND: The extended latissimus dorsi (ELD) musculocutaneous flap is one of the surgical techniques used for breast reconstruction. Preoperative preparation to determine the exact amount of flap tissue to be harvested is important to achieve a good outcome with autologous tissue reconstruction. However, few reports exist on objective preoperative volume prediction of ELD flaps. The purpose of this study was to quantify the elevated ELD volume as a preoperative plan. METHODS: Patients who underwent immediate or delayed breast reconstruction with ELD flap after mastectomy between March 2015 and January 2022 are included. (1) The ELD flap was designed preoperatively, X-ray contrast thread was applied along the design, and CT imaging was performed in the same lateral supine position as the surgical position. 3D images were constructed, and the volume-rendering method was used to obtain the integrated volume. (2) Intraoperative ELD flap volume was calculated using the water displacement method. The correlation between (1) and (2) was examined. RESULTS: (1) The mean preoperative predicted value was 290.2 mL and (2) the mean intraoperative ELD flap volume was 298.3 mL. The correlation coefficient between the two volumes was 0.93, indicating that they were correlated. CONCLUSION: We could quantify the ELD flap volume using the volume-rendering method with X-ray contrast threads. This study could be a useful method for preoperative prediction planning of the ELD flap in breast reconstruction.
