Background:
Lateral intercostal artery perforator (LICAP) flap for breast volume augmentation provides the benefits of addressing axillary tissue excess and avoiding intramuscular dissection. Previous experience with the LICAP flap in patients with prior breast conservation therapy (BCT) has led to the development of an extended version for massive weight loss (MWL) patients as well.
Methods:
A retrospective review of all cases of LICAP flaps was performed by a single surgeon. Data were subsequently extracted and analyzed including patient demographics, indication and timing of volume augmentation, complications, and follow-up length.
Results:
From 2016 to 2020, 12 patients underwent 16 LICAP flaps for volume augmentation. Indications for volume augmentation included deficits from prior oncologic surgery (ten patients) and loss of volume due to MWL (two patients). The average BMI was 29.9 kg/m2. Among the oncologic group, eight patients had delayed reconstruction, while two were immediate. Nine patients underwent radiation prior to volume augmentation. Eight of the 14 patients simultaneously received fat grafting. There were 4 cases of delayed wound healing that improved with local wound care. There were no statistically significant differences in complication rates between the oncologic and MWL groups. The average length of follow-up was 11.4 months.
Conclusions:
This study supports that the application of the LICAP flap can be effectively broadened from the oncologic population to the MWL population. If needed, extending the flap provides an option to simultaneously address excess axillary and back tissue.
