Skeletal Contour · Procedure
Skeletal waist narrowing is usually discussed as though the waist were an outline — something seen from the side or from behind. That is where RIBXCAR works, and for many patients it is the whole answer.
But some torsos are limited at the front. The lower border of the rib cage flares below the chest; a hard ridge shows at the costal margin when standing; the upper abdomen reads wide face-on even when the profile is good. No amount of work on the lateral and posterior ribs changes that, because the limiting structure is somewhere else. FRONTXRIB remodels the anterior costal margin — the front lower edge of the rib cage, and the line it dictates across the upper abdomen.
FRONTXRIB is a skeletal waist procedure that remodels the anterior costal margin — the front lower edge of the rib cage — for torsos limited at the front, where work on the lateral and posterior ribs cannot reach. It belongs to the same family of piezoelectric costal procedures as RIBXCAR.
This page is about the anterior costal margin and the upper-abdominal line. The technique, the instrument and the safety principles are shared with RIBXCAR and are explained in full there rather than repeated here.
If you have not read it, start with RIBXCAR — rib remodeling: how the bone is reshaped rather than removed, why the endpoint is defined by ultrasound, and what the published complication data shows. Everything on this page assumes it.
Origin
FRONTXRIB is one of the techniques developed by Dr. Raúl Manzaneda Cipriani in Lima, Peru, founder of AX — Aesthetic Xpert Scientific Lab, within the same family of piezoelectric costal procedures as RIBXCAR. Dr. Higuchi performs it as AX Asia Ambassador and teaches within that programme in Japan.
As with rib remodeling generally, this is performed by a small number of surgeons worldwide and techniques are not standardised between countries. Where a surgeon trained in it, and with whom, remains the most useful question you can ask.
Anatomy
The lower ribs are not one structure with one behaviour. The floating ribs, eleven and twelve, have no anterior attachment and angulate freely. The false ribs, nine and ten, do not: their cartilage joins the costal arch at the front, and that union resists angulation and transmits stress forward to the point where it is fixed.
This is not a technicality. It is why a waist can stop narrowing while the ribs behind it have already been addressed — the limit has moved to the anterior fixation point. Published work within the same technique family has shown how much difference the anterior attachment makes: in a 49-patient comparison, adding a false-to-floating conversion of ribs nine and ten produced a mean waist reduction of 17.04 cm at six months, against 8.70 cm without it.[2] Roughly double, from addressing the front rather than working harder at the back.
The anatomical measurements underlying costal surgery of this kind — the proportions and relationships of ribs ten, eleven and twelve, and the thoracoabdominal limits they define — have been described from a series of 83 computed tomography studies.[3] Design here is measured, not estimated.
Candidacy
Evidence
We would rather write that plainly than imply otherwise. What is published is the parent technique and the anatomy: RIBXCAR has a multicentre record of 3,805 cases across eight countries;[4] the behaviour of the anterior fixation point has been quantified;[2] and the costal measurements that govern design have been described from CT.[3]
FRONTXRIB is a younger technique whose evidence base is still being built. If certainty from published outcome data is what you need in order to consent comfortably, that is a legitimate reason to choose differently, and saying so is part of an honest consultation rather than an obstacle to one.
The safety principles are those of the parent technique, and they are not softened by the anterior location: the fracture must remain monocortical, the endpoint is what the ultrasound shows rather than what the surgeon hears, and the serious complications remain thoracic. An independent survey across several rib remodeling techniques put pneumothorax at 0.17 per cent of cases and concluded that in the hands of a well-trained surgeon with an adequate learning curve these procedures can be considered safe.[5] Those figures, and what they mean, are set out on the RIBXCAR page.
The Operation
Recovery
The compression is not optional. In a prospective series within this technique family, of the 12.5 per cent of patients who reported pain, more than half of that pain was attributable to misuse of the corset rather than to the fracture itself.[6] If you are not going to wear it as instructed, this is not the right operation for you.
Fees
| Item | Fee (JPY, incl. tax) |
|---|---|
| FRONTXRIB — anterior rib remodeling | ¥2,200,000 |
| RIBXCAR — rib remodeling | ¥2,200,000 |
| RIBXCAR × FRONTXRIB — combined | ¥4,400,000 |
| General anaesthesia | ¥165,000 |
| Standard set (anaesthetic, medication, compression garment) | ¥66,000 |
| Blood tests | ¥11,000 |
Deep-layer liposuction of the waist is almost always performed alongside skeletal work and is quoted separately — see the full fee schedule. Standard prices, not monitor prices. Your written quotation is the binding figure.
As with rib remodeling generally, this procedure is not covered by the one-year guarantee that applies to VASER liposuction, VASER 4D, Condense Rich breast augmentation and gynecomastia surgery.
Risks
This is elective surgery on the skeleton, adjacent to the chest cavity. It is substantially more invasive than soft-tissue contouring, it is not covered by health insurance in Japan, and its outcome cannot be guaranteed.
Questions
They treat different parts of the same rib cage. RIBXCAR changes the angle of the lower ribs at the side and back, which narrows the waist in outline — the silhouette you see from behind or in profile. FRONTXRIB addresses the costal margin at the front, which governs the upper-abdominal line and how the waist reads face-on and in three-quarter view. A patient can need one, the other, or both.
By where your waist stops narrowing. If your outline looks straight from the side or behind, the limit is usually the lateral and posterior ribs. If your outline is acceptable but the front of your torso flares below the chest, or a hard ridge shows at the lower border of the rib cage when you stand, the limit is anterior. This is assessed on examination rather than from photographs alone.
Yes, and for patients whose limit is skeletal in both directions it is the more complete answer. Performed together the fee is ¥4,400,000 including tax, rather than ¥2,200,000 for either alone. Whether combining them is appropriate in a single operation is a safety decision — operative time and recovery capacity — made at consultation, not a matter of preference.
No. As with RIBXCAR, the ribs are reshaped rather than resected, through percutaneous punctures rather than an incision, using a bone-selective ultrasonic instrument under real-time ultrasound. The structural continuity of the rib cage is preserved.
Not under that name, and we would rather say so. The parent technique, RIBXCAR, has a substantial published record, and the anatomical basis for anterior costal work — including the behaviour of the false ribs and their cartilaginous fixation to the costal arch — is published. FRONTXRIB itself is a younger technique whose evidence base is still being built. If certainty from published series matters to you, that is a legitimate reason to choose differently.
The surgical fee is ¥2,200,000 including tax, or ¥4,400,000 combined with RIBXCAR. General anaesthesia, the standard post-operative set and blood tests are additional. Deep-layer liposuction of the waist is usually performed alongside skeletal work and is quoted separately.
Plan for at least two weeks after surgery. That period covers early recovery, management of the external fixation, and at least one in-person follow-up before you are cleared to fly. Your arrival date before surgery is set separately in your written plan.
FRONTXRIB is one of the techniques developed by Dr. Raúl Manzaneda Cipriani in Lima, Peru, founder of AX — Aesthetic Xpert Scientific Lab, within the same family of piezoelectric costal procedures as RIBXCAR. Dr. Higuchi performs it as AX Asia Ambassador and teaches within that programme in Japan.
