Purpose Tuberous breast (TB) is a congenital abnormality of the breast, characterized by morphological, structural and cytological changes of the normal breast unit. The etiology of TB remains uncertain, although it is believed to be of embryological origin. Little attention has been paid to the pectoralis major muscle (PMM), which is fundamental to achieve the correction when the use of a prosthetic implant is necessary. The aim of this study is to define the anatomical characteristics of the pectoralis major muscle...
Read more Methods and materials Tuberous breast presents different degrees of severity and morphology, with clinical hallmarks including constricted breast base, reduced parenchymal volume, areolar herniation, and an elevated inframammary fold. A dual-plane technique is often recommended to provide both lower-pole expansion and upper-pole coverage. Despite extensive studies on glandular abnormalities, PMM alterations remain largely unexplored. In this retrospective study, participants were divided into two groups: 30 TB patients (TB group) and 30 controls (NON-TB group). Patients with Poland syndrome, chest wall deformities, prior breast...
Read more Results The study revealed significant differences in PMM morphology between TB and NON-TB groups [fig.2,3]. Both groups were comparable in height and body mass index (BMI): TB=162.9±7.1cm, BMI=24.1±5.4; NON-TB=164.3±6.3cm, BMI=23.1±3.4. TB patients exhibited higher PMM roundness (p= 0.035) and elongation (p= 0.038), suggesting a more spherical and stretched muscle structure. Principal x-axis-3 (smallest axis length in the x-plane) was significantly shorter in the TB group (p= 0.010) while principal z-axis-2 (second-largest axis length in the z-plane) was larger in TB patients...
Read more Conclusion These results provide the first quantitative evidence of alterations affecting the PMM in TB patients. These differences were found in different planes and volumetric shape features with potential surgical implications. The observed increased roundness and elongation combined with the different dimensions along the x-axis and the z-axis of the PMM may contribute to asymmetric implant coverage, positioning and stability in TB patients. These findings highlight the importance of tailoring surgical approaches to account for PMM geometry in these patients. Further...
