Objective This study aimed to compare breast symmetry and patient satisfaction with breast appearance between implant-based breast reconstruction using TiLoop Bra mesh combined with pectoralis major disconnection (IMR) and conventional implant reconstruction (IR), and to analyze differences in complications.

Methods This retrospective study included 59 patients administered IMR or IR in 2016 to 2018. Three-dimensional scanning was performed to objectively evaluate breast symmetry. The BREAST-Q scale was used to survey satisfaction with breast appearance, social psychosocial health, physical health, and sexual well-being.

Results There were no significant differences in age, TNM stage, and chemotherapy between the 2 groups (all P > 0.05). In 3-dimensional scanning data, patients who underwent IMR had better bilateral breast symmetry compared with those administered IR (all P < 0.001). Based on the BREAST-Q survey, the satisfaction rate was significantly higher for IMR compared with IR (P = 0.0368), whereas psychosocial health, physical health, and sexual well-being showed no significant differences between the 2 groups (all P > 0.05). The IMR model showed no obvious advantages in common complications, including hematoma, incision site infection, skin flap necrosis, and prosthesis exposure and rupture compared with IR; loss of skin and nipple sensations was evident in both groups. The IMR model was associated with reduced incidence of fibrous capsule contracture compared with IR (0% vs 18.75%, P = 0.0267). The incidence rates of pectoralis major disconnection syndrome after IMR and IR were 18.50% and 0%, respectively (P = 0.0161).

Conclusions Patients administered IMR have better breast symmetry and greater satisfaction with breast appearance compared with those treated by IR; however, IMR has unique complications, including pectoralis major disconnection syndrome.
