The Procedure

What Are Hybrid Buttock Implants?

Hybrid buttock augmentation is an advanced surgical technique that combines the placement of gluteal implants (prostheses) with autologous fat transfer (fat grafting). This dual approach harnesses the advantages of both methods: the predictable projection and firm structure provided by the implants, together with the soft coverage and natural contour supplied by the patient's own fat.

During the procedure, medical-grade silicone implants are placed in an intramuscular or subfascial plane, depending on the patient's anatomy. A fat transfer is then performed in the peripheral areas of the buttock to soften the implant edges, improve the transition with surrounding tissues, and refine the overall contour. The fat used is harvested beforehand via liposuction from donor areas such as the abdomen, flanks, or thighs.

This hybrid technique is particularly indicated for patients who desire a significant volume increase but do not have sufficient body fat to achieve the desired result with fat grafting alone. The final result is a buttock with greater projection, a rounded shape, and a natural feel, free from the visible edges that can be associated with the exclusive use of implants.

Benefits

Benefits of Hybrid Buttock Implants

The Best of Both Methods

Combines the structural projection of implants with the softness and naturalness of autologous fat, achieving a result superior to either technique alone.

Greater Volume and Projection

Ideal for patients who desire a significant augmentation and do not have sufficient fat for an exclusive BBL, guaranteeing the desired volume.

Softened Contour

Fat injected around the implant eliminates visible edges and creates a smooth, natural transition with the surrounding tissues.

Long-Lasting Results

Implants provide permanent volume, while the surviving transferred fat integrates definitively into the gluteal tissue.

Ideal Candidate

Who Is This Procedure For?

  • Individuals who desire a notable buttock augmentation but do not have sufficient body fat for an exclusive BBL.
  • Patients seeking maximum projection and volume combined with a natural contour and no visible implant edges.
  • Those wishing to improve the waist-to-hip ratio with a long-lasting, structurally stable result.
  • Adults over 18 in good health, with stable weight and realistic expectations regarding the procedure.
  • Patients who previously underwent a BBL with insufficient results and are seeking greater volume through a complementary approach.
Frequently Asked Questions

Your Questions Answered

Modern implants do not have an expiry date, but periodic review is recommended. According to manufacturers and SECPRE, an ultrasound or MRI check every 2–3 years is advisable. Replacement is considered if capsular contracture, rupture, or a desired aesthetic change occurs.
This is uncommon with the latest-generation implants. Silent rupture is detected at follow-up appointments; displacement or rotation is prevented through correct surgical technique and the post-operative compression garment.
It is the formation of scar tissue around the implant that can harden the area. It occurs in a small percentage of cases; we use textured or smooth implants according to anatomy and antimicrobial protocols to minimise this risk.
After full recovery you can resume normal life. Sensitivity is maintained in the majority of cases. Your plan is adjusted according to your activity level and the type of implant chosen.
During the first weeks the implant settles into its pocket. The definitive result is appreciated between 3 and 6 months, once swelling subsides and the tissues adapt to the implant.
Honest Information

Risks and Safety of Hybrid Buttock Implants

Every surgical procedure, however minimally invasive, carries risks. We explain them transparently so you can make a fully informed decision. At NATURAL FIT® Body Contouring we apply the strictest protocols to minimise them as much as possible.

Capsular Contracture

Hardening of tissue around the implant. Uncommon with modern implants and correct technique; managed medically or with revision surgery depending on grade.

Rotation or Displacement

The implant may shift from its ideal position in isolated cases. Precise pocket technique and the post-operative compression garment minimise this risk.

Implant Rupture

Low risk with latest-generation implants. Detected at scheduled follow-up appointments with ultrasound or MRI, and replaced if it occurs.

Haematomas and Seromas

Accumulation of blood or fluid around the implant. The compression garment and drainage minimise their occurrence.

Sensitivity Changes

Temporary alterations in sensation in the area. Normal sensitivity returns progressively in the majority of cases.

Infection

Low risk thanks to the aseptic protocol, antibiotic prophylaxis, and pocket selection. It is the complication requiring the most immediate attention if it arises.

According to the Spanish Society of Plastic, Reconstructive and Aesthetic Surgery (SECPRE) and the Spanish Association of Aesthetic Plastic Surgery (AECEP), current implants have an excellent safety profile when placed by an accredited plastic surgeon in a hospital setting with the recommended periodic follow-up.
