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
