Hug Flap and Hamdi Hammock: Two Innovative Techniques for Enhancing Aesthetic Outcomes in Deep Inferior Epigastric Artery Perforator Breast Reconstruction.

[BACKGROUND] Achieving optimal aesthetic outcomes in deep inferior epigastric artery perforator (DIEP) flap breast reconstruction remains a challenge, often necessitating additional procedures for refinement. This study presents two innovative techniques (the hug flap and Hamdi hammock) aimed at enhancing breast projection and inframammary fold (IMF) definition in DIEP flap reconstruction.

[METHODS] The hug flap technique uses de-epithelialized caudal mastectomy skin to augment breast projection, whereas the Hamdi hammock uses a percutaneous purse-string suture to define the IMF. A retrospective review of 782 patients who underwent DIEP flap breast reconstruction between 2007 and 2023 was conducted.

[RESULTS] The hug flap group required significantly less additional fat grafting compared to other techniques (11% versus 27% and 22%). No total flap losses occurred in the hug flap group, and fat necrosis rates were low. The Hamdi hammock was used in 405 patients with a mean of two lipofilling sessions. Complications were minor and no stitches required removal.

[CONCLUSIONS] The hug flap and Hamdi hammock techniques offer effective and safe methods for enhancing breast projection and IMF definition in DIEP flap reconstruction. These techniques may reduce the need for additional procedures and improve aesthetic outcomes.
