摘要

Purpose

To quantify the breast computed tomography (CT) parameters in IS patients. Patients’ perceptions of their breast appearance before/after scoliosis surgery were also assessed with Breast-Q™ questionnaire.

Outcome measure

Concave/convex side breast volume difference (BVD), computed tomographic external breast appearance parameters (extraversion angle (EA), coverage angle (CA), axial breast height (ABH), nipple-to-sternum distance (NSD), thoracic rib cage parameter (inclination angle (IA)), and Breast Satisfaction and Psychosocial Well Being domains of Breast-Q Q™ questionnaires.

Methods

This was a prospective study of 50 IS patients recruited between June 2017 and December 2018 who had pre-operative CT scans available for review. Pre-operative radiological parameters as stated above were evaluated. Breast volume difference (BVD) was calculated using the formula: 100 * {(CC BV – CV BV)/[(CC BV + CV BV)/2]}. Breast-Q™ questionnaires were administered pre-operative and post-operatively. The percentage of patients who achieved the minimal clinically important difference (MCID) was reported.

Results

Thirty-three patients (66%) had significant BVD with the concave side larger in 52.0% of patients. BVD had significant correlation with ABH, NSD, CA, and EA. There was no significant correlation between pre-operative Cobb angle with BVD and IA. There was also no significant correlation between Tanner stage and the radiological parameters. Breast satisfaction and psychosocial well-being domains improved after surgery and the satisfaction with breast domain minimal clinically important difference (MCID) was achieved in 83.7% of patients, while the psychosocial well-being domain reached the MCID in 75.5% of patients (p < 0.001).

Conclusion

Scoliosis led to significant breast asymmetry among patients with smaller volume on the convex side. Changes in breast volume (BV) contributed significantly towards the external breast appearance. Patient’s breast satisfaction and psychosocial well-being improved post-operatively and, in the majority, MCID was achieved.
