Some people considering a change to buttock shape or projection may not have enough donor fat for fat transfer or may prefer not to undergo liposuction. In these circumstances, other surgical approaches may be discussed according to the person’s anatomy, health, tissue characteristics and goals.
Dr Mark Kohout is a Harvard Trained Specialist Plastic Surgeon based in Sydney with more than 25 years of clinical experience. He consults with patients considering gluteal implants or other buttock reshaping procedures and provides individual information about suitability, limitations, potential risks and recovery.
What Determines the Natural Shape of the Buttocks?
Buttock shape is influenced by skeletal structure, gluteal muscle development, fatty tissue, skin quality and the position of the surrounding tissues. These features vary between individuals and may also change with ageing, weight variation or previous surgery.
The width and angle of the pelvis affect the foundation of the gluteal region, while muscle and fatty tissue contribute to volume and projection. Skin elasticity and the relationship between the lower back, waist, hips and thighs can also influence how the area appears.
- Pelvic width and hip-joint angles
- Gluteal muscle size and position
- Natural fat-distribution patterns
- Skin and connective-tissue support
- Changes associated with ageing or weight variation
Why Might Fat Transfer Not Be Suitable for Everyone?
Fat transfer may not be suitable when there is insufficient donor fat, when liposuction is not preferred or when health and surgical history affect candidacy. Some patients may also prefer an implant-based or tissue-focused procedure.
Fat transfer requires enough suitable fatty tissue to be collected from another area of the body. The amount available, donor-site quality and individual medical circumstances all influence whether this method can reasonably be considered.
Common reasons for considering another approach include:
- Limited fatty tissue available for transfer
- Preference not to undergo liposuction
- Previous procedures affecting possible donor areas
- Medical factors that influence surgical planning
What Surgical Options Are Available Without Fat Transfer?
Options that do not use transferred fat may include gluteal implants or individually planned buttock reshaping surgery. The appropriate approach depends on whether the main concern involves volume, projection, tissue position, asymmetry or skin laxity.
These procedures do not provide the same type of change and are not interchangeable. Gluteal implants add volume, while tissue-focused reshaping may address the position or distribution of existing skin and soft tissue without relying on fat grafting.
Possible approaches may include:
- Gluteal implant surgery
- Tissue-focused buttock reshaping
- Removal or adjustment of excess skin in selected patients
How Does Gluteal Implant Surgery Change Buttock Shape?
Gluteal implant surgery uses semi-firm silicone implants to add volume and projection to the buttock region. The implant size, shape and position are selected according to the patient’s anatomy and available tissue coverage.
The implants are placed through an incision near the crease between the buttocks and positioned in relation to the gluteal muscle. The precise technique is determined during surgical planning and may differ according to body structure, tissue thickness and the intended degree of change.
The procedure generally involves:
- An incision positioned near the buttock crease
- Creation of a pocket for the implant
- Selection of an implant suited to the available tissues
- Closure of the incision and application of dressings
Who May Be Suitable for Gluteal Implants?
Gluteal implants may be considered by patients with limited donor fat who are seeking a change in buttock volume or projection. Suitability also depends on general health, tissue coverage, medical history and the ability to follow recovery instructions.
An implant is not appropriate for every patient, and the available soft tissue must be sufficient to cover and support it. Dr Mark Kohout assesses the buttocks, pelvis, skin, muscle structure and overall proportions before discussing whether implant surgery may be an option.
Factors considered during assessment include:
- The amount of available soft-tissue coverage
- Overall health and surgical history
- Stability of body weight
- The type and degree of change being considered
- Capacity to follow sitting and activity restrictions
What Should I Know Before Choosing Gluteal Implants?
Gluteal implants are medical devices and may require monitoring, revision or removal in the future. Patients need to understand the potential complications, scars, recovery demands and limitations of the procedure before deciding.
Implants can provide a relatively consistent increase in volume, but they cannot guarantee a particular appearance or exact symmetry. Their position, visibility and how noticeable they feel can vary according to anatomy, tissue coverage, healing and activity.
Important limitations include:
- Implants do not respond to weight change like natural fatty tissue
- Implant edges may be more noticeable in patients with limited tissue coverage
- Scars are an unavoidable part of surgery
- Further surgery may be required if circumstances change
Can Buttock Reshaping Be Performed Without Adding Volume?
Buttock reshaping may be considered when the concern relates more to tissue position, laxity or asymmetry than to reduced volume. These procedures work with the patient’s existing skin and soft tissues rather than adding transferred fat.
The surgical plan depends on the location and extent of tissue change, as well as previous operations and weight variation. In some patients, reshaping may involve removing or repositioning selected tissues, although the appropriate technique can only be identified after examination.
This type of surgery may focus on:
- Repositioning selected skin and soft tissue
- Reducing tissue laxity in a defined area
- Addressing selected differences in shape or symmetry
- Improving the relationship between the buttocks and surrounding areas
Who May Consider Tissue-Focused Buttock Reshaping?
Tissue-focused reshaping may be considered by people who do not want implants or fat transfer and whose concern involves skin or soft-tissue position. It may also be discussed after significant weight change, ageing or previous surgery.
This approach is unlikely to be suitable when the primary goal requires substantial additional volume. Dr Mark Kohout examines tissue quality, skin elasticity, gluteal structure and surrounding areas to determine what degree of change may be possible.
It may be discussed when there is:
- Tissue laxity following substantial weight change
- A preference to avoid implants
- A concern focused on shape rather than volume
Can Exercise Support Buttock Shape Before or After Surgery?
Resistance exercise can support gluteal strength and muscle development, but it cannot reproduce the structural change created by an implant or tissue-removal procedure. Exercise may still contribute to physical conditioning before surgery and muscle maintenance after recovery. For more information, see why your buttocks may still look flat despite exercise. Exercise may still contribute to physical conditioning before surgery and muscle maintenance after recovery.
Patients should discuss their usual training routine during consultation because activity levels can affect surgical planning and recovery arrangements. Exercise must be paused or modified after surgery and resumed gradually only when cleared by the treating surgeon.
Exercise may assist with:
- Maintaining gluteal muscle strength
- Supporting general physical conditioning
- Preserving mobility before surgery
- Returning to normal activity after recovery
It cannot:
- Change pelvic bone structure
- Replace substantial lost tissue volume
- Correct significant skin laxity
What Happens During a Consultation with Dr Mark Kohout?
A consultation involves an assessment of anatomy, medical history, goals and possible treatment options. It also provides time to discuss what surgery can and cannot address, along with scars, risks, recovery and long-term considerations.
Dr Mark Kohout examines the buttock area, surrounding proportions, skin quality, muscle structure and available tissue coverage. He also reviews medications, previous procedures, health conditions, nicotine use, work requirements and regular physical activities.
A consultation may include:
- Review of medical and surgical history
- Physical assessment of the gluteal region
- Discussion of the specific concern
- Comparison of available procedures and alternatives
- Explanation of potential complications and recovery

What Does Recovery After Buttock Surgery Involve?
Recovery may involve swelling, discomfort, changes to sitting or sleeping positions and temporary restrictions on work and exercise. The length and requirements of recovery depend on the operation and the individual healing response.
Patients receive procedure-specific instructions about wound care, garments, movement, medications and follow-up appointments. Recovery estimates are general guides, and patients may progress at different rates depending on their health, operation and healing.
Practical recovery arrangements may include:
- Organising help at home during early healing
- Modifying sitting and sleeping positions
- Taking time away from physically demanding work
- Attending scheduled postoperative reviews
What Risks Are Associated with Surgery Without Fat Transfer?
Gluteal implants and tissue-focused buttock reshaping carry general surgical risks as well as procedure-specific complications. No surgical outcome can be guaranteed, and additional treatment or revision surgery may sometimes be required.
General risks include bleeding, infection, blood clots, anaesthetic complications, delayed wound healing, scarring, changes in sensation and asymmetry. Implant surgery may also involve displacement, fluid collection, firmness, visibility, implant awareness or removal.
Potential complications may include:
- Infection, bleeding or fluid collection
- Delayed healing or wound separation
- Noticeable, raised or widened scars
- Asymmetry or contour irregularity
- Implant movement, awareness or removal
Buttock Shape Without Fat Transfer FAQs
Can this type of surgery be planned around long periods of sitting, such as office work or travel?
Yes. Surgical planning includes discussion of work patterns and daily activities. Where possible, timing and recovery guidance are adjusted to suit individual routines.
Does age influence whether non-fat transfer options are suitable?
Age alone is not a deciding factor. Suitability is based on overall health, tissue characteristics, and individual goals discussed during consultation with Dr Mark Kohout.
How does previous lower back or pelvic surgery affect planning?
Previous surgery is carefully reviewed as it may influence anatomy or healing considerations. This information helps guide procedure selection and risk discussion.
Is it possible to change implant size years after surgery?
In some cases, further surgery may be considered if goals or circumstances change. This would involve a new assessment and discussion of potential risks and benefits.
Will this procedure affect how clothing fits rather than overall body size?
Some individuals notice changes in how garments sit or feel rather than a change in clothing size. This varies depending on the approach used and personal anatomy.
Are there seasonal considerations when planning surgery in Sydney?
Some patients prefer scheduling surgery outside periods of extreme heat or major travel plans. Timing is discussed to align with comfort and recovery needs.
Can posture or spinal alignment influence outcomes?
Posture and pelvic alignment can affect how body shape appears. These factors are considered during assessment, particularly when planning implant placement.
How long should I wait after significant weight change before considering surgery?
It is generally recommended to allow weight to stabilise before surgery. This supports more reliable planning and recovery expectations.
Will exercise habits need to change long term?
Exercise is usually paused during early healing and then gradually resumed. Long-term activity is often encouraged once recovery is complete and cleared by the surgeon.
Is it appropriate to seek a second opinion before deciding?
Yes. Patients are encouraged to feel confident in their decision-making process. Seeking additional professional input is considered a reasonable part of informed consent.

What Should I Consider Before Deciding on Surgery?
The decision should be based on personal goals, medical suitability and a clear understanding of potential limitations and complications. It should not be driven by pressure from another person, online trends or expectations of a guaranteed result.
Patients should consider whether the possible change is proportionate to the recovery, scars, costs and likelihood of future surgery. Taking time to review the information or seek a second medical opinion can support informed consent.
Questions to consider include:
- What specific change am I seeking?
- Am I prepared for scars and recovery restrictions?
- Do I understand the possible complications?
- Would I be comfortable seeking a second opinion?
- Have I allowed enough time to consider the decision?
What Are the Next Steps for Those Considering Gluteal Adjustment?
