Fat harvest and preparation
Liposuction harvests fat from areas with an ample supply—commonly the abdomen, waistline, back, or thighs—so donor tissue both shapes the harvest site and supplies graft material. Dr. Sahar evaluates donor zones during consultation to balance contouring goals. Harvested fat is handled aseptically in the operating room to preserve viable cells for transfer.
Once removed, fat is processed to remove impurities and excess fluid so the remaining tissue is concentrated for grafting. Purified fat is placed through small incisions and injected in layers to build volume and encourage even graft take. Layered placement and careful handling influence how much transferred tissue survives.
Ultrasound-guided injection and safety
Dr. Sahar performs ultrasound‑guided BBL (uBBL) for every patient; intraoperative ultrasound gives real-time visualization of soft-tissue layers. That visualization helps avoid injecting fat into muscle or large vessels—an identified safety concern—by confirming the cannula's position in the subcutaneous plane before each injection.
Dr. Sahar has investigated gluteal augmentation safety himself, and uBBL reflects that focus on risk reduction. Ultrasound guidance is a procedural choice that prioritizes visualization over blind placement; patients should discuss how technology, surgeon experience, and personal anatomy shape intraoperative decisions during their consultation.
Recovery and postoperative care guidelines
Patients are advised to avoid sitting or lying directly on the buttocks for a few weeks while transferred fat establishes a blood supply. That period is critical because graft survival depends on revascularization; surgeons monitor contour and tissue health during follow-up and may recommend strategies to reduce pressure on the graft.
Follow-up visits are arranged from our Beverly Hills office, convenient to Rodeo Drive, Santa Monica Boulevard, and area parking. Local patients and visitors find appointments can fit into workdays, shopping trips, or hotel stays. Expect guidance on activity, dressings, and when to return to normal routines specific to your healing.
