Objective  To explore the surgical technique and preliminary safety and aesthetic results of endoscopic removal of injectable Amazingel with/without immediate prepectoral implant-based breast augmentation for patients. Methods The clinical data of 25 patients who underwent endoscopic removal of injectable Amazingel with/without immediate prepectoral implant-based breast augmentation between April 2020 and January 2024 and met the selection criteria was retrospective analysed. The patients’ age ranged from 33 to 73 years, with a mean of 50.4 years, and the body mass index ranged from 16.8 to 26.6 kg/m2, with a mean of 21.5 kg/m2. They were all bilaterally injected with Amazingel, and the time between initial injections and surgery ranged from 17 to 26 years, with a mean of 21.4 years. Early safety was evaluated by the incidence of early postoperative complications, and early aesthetic results were evaluated using Harris scores (including breast shape satisfaction, sensation satisfaction, and elasticity satisfaction) at 3 months after operation. Results  There were 9 cases underwent Amazingel removal (group A) and 16 cases underwent Amazingel removal with immediate prepectoral implant-based breast augmentation (group B). Intraoperative removal of Amazingel ranged from 808 to 1 285 mL, with a mean of 1 050.7 mL; the mass of the capsule removed ranged from 36 to 169 g, with a mean of 103.6 g; and a gross anatomical prosthesis was used with a median size of 345 mL (range, 315-355 mL). The operation time ranged from 95 to 395 minutes, with a mean of 194.2 minutes; and the cost of the procedure ranged from 8000to 91 000 yuan, with a mean of 33 000 yuan. Patients had a median follow-up time of 22.7 months (range, 3.0-48.1 months). There was 1 case of intraoperative skin burn due to the operation of the electric scalpel, which healed naturally after operation without flap necrosis. There was no adverse conditions such as prosthesis outline showing, ripple sign, and capsular contracture during follow-up; a small amount of Amazingel residue was found in 2 patients at 1 year after operation. The Harris score at 3 months after operation was used to evaluate the early aesthetic results, and the breast shape, elasticity, and sensation satisfaction of group A were lower than group B, but the differences between the two groups were not significant (P>0.05). Conclusion  Endoscopic removal of injectable Amazingel with/without immediate prepectoral implant-based breast augmentation is safe in the early stage with good aesthetic results, and it is also recommended that patients who had the indications for combined immediate breast augmentation after removal to rebuild the breast appearance.
