Outcomes after elevation of serratus anterior fascia flap versus serratus muscle flap in direct-to-implant breast reconstruction following mastectomy: a prospective study.

The purpose of this study was to compare postoperative pain between SF flap and serratus anterior muscle (SM) in direct-to-implant breast reconstruction. This is a prospective cohort study that included 53 women diagnosed with breast cancer who underwent mastectomy and one-stage implant-based breast reconstruction from January 2020 to March 2021. Twenty-nine patients (54.7%) had SF elevation, and 24 patients (45.3%) underwent SM elevation. We evaluated patient-reported early postoperative pain on the first day after surgery. Also, it was reported that all surgical complications in the first month and patient reported outcomes (PROs) were measured with the BRECON 23 questionnaire. The serratus fascia group used implants with larger volumes, 407.6 ± 98.9 cc (p < 0.01). There was no significant difference between the fascial and muscular groups regarding the postoperative pain score reported by the patients (2 versus 3; p = 0.30). Also, there was no difference between the groups regarding early surgical complications and PROs after breast reconstruction. The use of SF seems to cause less morbidity, which makes the technique an alternative to be considered in breast reconstruction. Although there was no statistical difference in postoperative pain scores between the fascia and serratus muscle groups.
