Introduction:
The omental fat-augmented free flap (O-FAFF) is a recently developed technique for autologous breast reconstruction. Our aim of the study is to evaluate the outcomes of our early case series. We assess the O-FAFF donor site morbidity in terms of postoperative pain, narcotic, and antiemetic use.
Methods:
A retrospective analysis of patients undergoing O-FAFF from 2019 to 2021 was performed. Patients were evaluated for demographic data, operative time, hospital course, and complications. Mean pain scores (1-10 scale) and narcotic pain medication use in oral morphine equivalents and doses of antiemetic medications during their hospital course were analyzed. We compared outcomes of our O-FAFF group with those of a control group of patients who underwent breast reconstruction with traditional free abdominal tissue transfer.
Results:
A total of 14 patients underwent O-FAFF breast reconstruction, representing 23 breasts. Patients had an average age of 48.5 years (±2.3 years) and body mass index of 22.6 kg/m 2 (±1.09 kg/m 2 ). Average follow-up was 232 days (±51 days). Average mastectomy weight was 245.6 g (±30.2 g) and average O-FAFF weight was 271 g (±31.7 g). Average pain scores on postoperative day 1 (POD1), POD2, and POD3 were 3.1 (±0.28), 2.8 (±0.21), and 2.1 (±0.35), respectively. The average narcotic use by patients in oral morphine equivalents on POD1, POD2, and POD3 are 24.3 (±5.5), 21.9 (±4.6), and 6.2 (±2.4), respectively. Total narcotic use during hospital stay was 79.4 mg (±11.1 mg). Average pain scores and narcotic use are significantly lower when compared with a previously published cohort of patients who underwent autologous breast reconstruction with free abdominal tissue transfer ( P < 0.05). Average antiemetic use was lower in the O-FAFF group compared with the control group: 3.5 versus 4.8 doses ( P = 0.6). Hospital length of stay was 3.0 days (±0.0 days). No complications were noted (0%). Patients were universally satisfied with their reconstructive outcome (100%).
Conclusions:
The O-FAFF is proven to be a viable method of autologous breast reconstruction. Early series of patients undergoing O-FAFF reconstruction suggest a lower donor site morbidity as demonstrated by lower postoperative pain scores and lower consumptions of narcotic pain medications.
