Patients researching surgical waist contouring options often come across two distinct procedures: RibXcar rib remodelling and rib removal surgery. While both involve the lower ribs, they work in fundamentally different ways and carry different risks, recovery requirements, and surgical implications. Understanding how they differ is an important part of being well-informed before booking a consultation.
What Is Rib Removal Surgery?
Rib removal surgery, also known as rib resection or costectomy, involves the surgical removal of portions of the lower floating ribs. These are the ribs located lowest in the rib cage and have no direct connection to the sternum. The outer portions of ribs 10, 11, and 12 are the most commonly targeted, though this varies depending on the individual patient and the approach used.
The procedure is performed under general anaesthesia. Incisions are made on the back or flanks to access the ribs, which are then partially removed. Because actual bone is removed, the structural change to the rib cage is permanent.
Recovery from rib removal surgery involves a longer healing period due to the more extensive nature of the operation. Incisions will leave visible scarring, the appearance of which varies between patients depending on individual healing, skin type, and the surgical approach used.
What Is RibXcar Rib Remodelling, and How Does It Work?
This is a technique that reshapes the lower ribs without removing them. Using a specialised instrument called a piezotome, which produces high-frequency vibrations of up to 30,000 per second, the outer layer of the rib bone is carefully weakened through tiny entry points of approximately one millimetre or less. Controlled manual pressure then creates a monocortical fracture, meaning only the outer layer of the bone is affected, and the ribs are repositioned to reduce the width of the lower torso.
During the procedure, ultrasound is used from start to finish. This helps see the ribs in real time, assess the angle and extent of each fracture, and confirm when the work is complete. Because the rib cage stays structurally intact, the bones continue to protect the lungs and surrounding organs throughout.
After the procedure, you may be advised to wear a compression garment continuously for about eight weeks while the bone heals in its new position. Scarring at the entry points can differ between patients, depending on individual healing and skin type. Results are not the same for everyone, and a detailed consultation with a qualified medical practitioner is important before you decide to go ahead.
How Do the Two Procedures Differ in Terms of What Happens to the Rib?
The most significant difference between the two procedures is what happens to the bone. In rib removal surgery, portions of the rib are physically taken out and do not grow back. The change to the structure of the rib cage is therefore permanent and not dependent on post-operative garment wear.
With RibXcar rib remodelling, no bone is taken out. Small, controlled fractures are made in the outer layer of the rib so it can be moved, and the rib cage then heals into its new position in the weeks after surgery. Because this process relies on the bone healing in that new position, wearing your compression garment as advised during recovery is an important part of your care. If the garment is not worn as recommended, the planned outcome of the surgery may be less predictable.
Both procedures involve the lower floating ribs, but the surgical approach, the permanence of the structural change, and the post-operative requirements differ between them. A consultation is needed to understand which approach may be suitable for your anatomy and circumstances.
What Are the Differences in Scarring?
Rib removal surgery requires incisions to access and remove the ribs. These incisions leave visible scars, typically located on the back or flanks. The size and appearance of these scars will vary between patients depending on the surgical approach, individual healing, and skin type.
Rib remodelling uses very small entry points of about one millimetre or less instead of larger incisions. Scarring at these entry points can differ between patients and depends on individual healing and skin type. The appearance of these marks varies from patient to patient and can change over time.
Patients for whom visible scarring is a significant concern should discuss both options in detail during a consultation to get a realistic assessment based on individual anatomy and skin characteristics.
What Are the Differences in Recovery?
Recovery from rib removal surgery involves a longer healing period due to the more extensive nature of the operation. Patients can expect a longer period of restricted activity, and post-operative pain tends to be more significant in the initial weeks. The use of a compression or reshaping garment is still part of the recovery process, though the structural change from bone removal is not dependent on garment wear in the same way as RibXcar.
Recovery after rib remodelling can involve soreness and swelling in the treated area during the first few weeks. You may be asked to wear a compression garment at all times for about eight weeks and to reduce physical activity during this period. How closely the garment instructions are followed can affect how the bone settles as it heals, and outcomes can differ between patients.
In both cases, specific post-operative instructions will be provided, and the timeline for returning to normal daily activities, exercise, and work will depend on individual healing and recovery.
Are the Risks the Same for Both Procedures?
Both procedures carry surgical risks, and neither should be approached without a thorough consultation and informed consent process. Some risks are specific to each approach, and others are shared.
Risks associated with rib removal surgery include nerve pain, prolonged soreness, fluid accumulation (seroma), infection, and visible scarring. Because bone is permanently removed, any complications arising from the structural change cannot be reversed.
Risks associated with rib remodelling include pneumothorax (air around the lung) due to the proximity of the ribs to the lung tissue, nerve irritation, asymmetry, difficulty with bone healing in its new position, infection or reaction at the entry points, and outcomes that differ from expectations. Individual results vary, and a detailed discussion of all risks is an essential part of the pre-operative process.
Why Choose Dr Perron for RibXcar Rib Remodelling Surgery in Brisbane
Dr Justin Perron is a Specialist Plastic and Reconstructive Surgeon holding the Fellowship of the Royal Australasian College of Surgeons in Plastic Surgery (FRACS Plastics). He is a member of the Australian Society of Plastic Surgeons (ASPS) and the Australasian Society of Aesthetic Plastic Surgery (ASAPS Aust.), and is registered with AHPRA as a specialist plastic and reconstructive surgeon.
Dr Perron has undertaken specialist certification in the RibXcar technique through a training program in Paris, which is recognised internationally as a specialist training program for this procedure. The Paris program covers patient assessment, treatment planning, the surgical technique itself, and the post-operative protocols specific to RibXcar. This training is in addition to his broader background in plastic and reconstructive surgery spanning more than a decade in Brisbane and across Queensland.
A consultation with Dr Perron gives you the opportunity to discuss both procedures, ask questions about your anatomy, and receive a clinical assessment of which option, if any, may be appropriate for your circumstances. All surgical procedures carry risk, individual results vary, and a thorough pre-operative consultation is an essential part of any surgical decision.
