A clinical observation of stage I implant breast reconstruction for mass-like granulomatous lobular mastitis.

Abstract

Granulomatous lobular mastitis (GLM) is a chronic benign inflammatory breast disease, and mainly mass-like granulomatous lobular mastitis (MGLM) clinically. There are few reports on applications of stage I implant breast reconstruction in GLM. This observational study was conducted to evaluate the safety and efficacy of stage I implant breast reconstruction in the treatment of MGLM. Patients suffering from MGLM who visited at hospital from April 2019 to June 2020 were selected and graded according to the magnetic resonance imaging (MRI) examination. Patients with MGLM were grouped into the prosthesis implantation group and the traditional treatment group according to their preferences. Clinical parameters of the two groups were analyzed before and after surgery, such as postoperative infection, recurrence, and satisfaction with appearance and aesthetics were observed. To evaluate the safety and efficacy of the implant breast reconstruction in MGLM. There were 59 cases of MGLM, 31 cases of grade 3-4 GLM, 11 cases of bilateral metachronous GLM. There were 18 patients in the prosthesis implantation group, including 9 patients with bilateral metachronous GLM, 2 patients with synchronous GLM, and 41 patients in the traditional treatment group. All the patients were followed up with a median of 17.5 months. One patient in the observation group had an infection on the reconstructed side 3 weeks after surgery, and the implant was retained after 2 weeks of conservative treatment such as antibiotics. Two patients in the prosthesis implantation group were not satisfied with size of the reconstructed breast was smaller than the opposite side. In the traditional treatment group, there were 3 cases of postoperative infection or delayed wound healing, and 26 cases of postoperative breast asymmetry. For patients with MGLM, it is safe to select stage I prosthesis implantation after conservative treatment, with exact effect and high patient satisfaction.
