Rib cartilage grafts

When there is not enough septum left to rebuild a nose, the surgeon takes cartilage from a rib, either the patient's own or one supplied by a tissue bank. That covers most revisions, most large augmentations and any nose whose septum has already been harvested. It is the material that makes big reconstruction possible, and what goes wrong with it is that carved rib bends: about 3% in pooled data, with a chest scar as the standing cost of taking it.

What the evidence says

Four findings that hold across the pooled analyses.

Rib is safe, and warping is its price

Three separate meta-analyses of autologous costal cartilage agree closely. Warping came out at 3.05%, 3.08% and 5.2%, resorption at 1.2%, 0.22% and 0.9%, infection at 1.45%, 0.56% and 0.6%, displacement at 0.39% and 0.6%. Donor-site problems are dominated by the chest scar, hypertrophic scarring 2.08% and 5.45%, with pneumothorax at or near zero across 491 and 1,648 pooled patients. Reported revision rates differ by what each analysis counted, 2.25% in one and 14.07% in another, but the direction is stable.

The processing decides the risk of donated rib

Seven studies and 1,184 patients, split by how the cadaveric cartilage was prepared: infection rates matched autologous overall; alcohol-preserved grafts warped significantly less; the excess resorption risk sat entirely in the irradiated subgroup; fresh-frozen behaved like the patient's own rib. Operating time was 66.56 minutes shorter with the donated graft. A survey of 41 tissue banks found twelve distinct processing protocols and no standard, so "cadaveric rib" on a consent form is not one thing.

Warping has causes outside the cartilage

The classical answer is to carve from balanced, concentric cross-sections and to let the graft sit in saline and declare itself before it is used. A 2023 series adds an external cause: an incompletely removed hump underneath a dorsal graft bends it in the sagittal plane. Design helps too, a circumferentially split X-shaped tip graft held its position across forty-five patients, and dicing the cartilage removes the problem entirely at the cost of visible irregularity in 5.3%.

Age decides whether the patient's own rib is usable

Costal cartilage calcifies. In 662 Caucasian adults the prevalence of calcification was 89.6%, and nearly everyone over 50 had some, which changes how the cartilage carves, how it holds a suture and whether it is worth harvesting at all. The published recommendation is a sex-specific age threshold beyond which a chest CT before surgery is informative.

How it is done

The steps, and what is being traded at each one.

Choosing the source

Septum first, because it is already exposed, straight and free. Ear next, for rim support, camouflage and composite grafts, springy, curved and limited in volume. Rib when structure is needed: a dorsal graft, an L-strut reconstruction, a septal extension graft in a nose with nothing left. The decision is made before the operation, because it changes the consent, the theatre time and the recovery.

Rests on: Cochran and Gunter · and cartilage grafts in the literature.

The harvest

Usually the sixth to eighth rib through a short incision at the rib margin or in the inframammary crease, taking cartilage while sparing perichondrium where possible, and checking the pleura before closing. Alternative incisions exist for the scar: a trans-areolar approach improved the scar and raised pneumothorax risk, and a laparoscopic trans-umbilical technique reported lower early pain scores against open harvest in 40 patients.

Rests on: Zhao et al., trans-areola harvest · TUSILS-SRA harvest technique.

Carving

Balanced cross-sections, oblique split, or diced. The graft is soaked and watched before it is placed. Where a straight solid graft is needed and the cartilage will not hold, layered constructions are used instead, perichondrium, a rib lamina and fascia in one sandwich, reported in more than 300 revision cases.

Rests on: Robotti et al., the SPLF graft · Xu et al..

Where it goes

Dorsal onlay to raise a low or collapsed bridge; L-strut reconstruction where the septum has failed; a caudal septal extension graft to hold tip projection and rotation; extended spreader grafts to straighten a deviated middle vault; lateral crural struts to rebuild a collapsed sidewall; tip grafts under thin skin, usually camouflaged with fascia.

Autologous or donated

The patient's own rib: their tissue, no cost, a chest incision, an hour of operating, and calcification with age. Donated rib: no chest incision, an hour saved, a supply cost, and a complication profile that depends on the processing. In functional rhinoplasty specifically, one 259-patient cohort found four-fold higher revision odds with cadaveric rib; a single-institution comparison put revision at 14.8% for the patient's own rib and 14.6% for irradiated donor rib. It is a real choice with real trade-offs, and it should be discussed by name.

The terms, defined

What the words on the consent form mean.

  • Autologous: the patient's own tissue. Homologous (allograft), another person's, from a tissue bank. Alloplastic, a manufactured implant. [42681592]
  • Costal cartilage: rib cartilage, the largest available source of graft material. [36071242]
  • Fresh-frozen, irradiated, alcohol-preserved: the three preparations of donated rib. Irradiation is associated with more resorption; alcohol preservation with less warping; fresh-frozen behaves closest to autologous. [42681592]
  • Warping: a carved graft bending after implantation, from its own internal stresses or from something underneath it. [36071242, 36656674]
  • Resorption: the graft being absorbed over months to years, so the shape it created flattens. [25429595]
  • Calcification: rib cartilage hardening with age; present in 89.6% of Caucasian adults and near-universal over 50. [41145129]
  • Diced cartilage in fascia (DCF): cartilage cut small and wrapped in fascia to build a dorsum with no edges. Cannot warp; can show as irregularity. [34357798]
  • Perichondrium: the sheath around cartilage; sparing it at harvest is thought to help the donor site and is used as a graft layer in its own right. [40826294]
  • L-strut: the L-shaped dorsal and caudal septal support that keeps the nose standing, and the thing rib is used to rebuild when it has failed. [20206752]
  • Donor-site morbidity: what the harvest costs: chest scar, pain, rarely a pleural tear or pneumothorax. [25429595, 31960891]

What to ask before agreeing to a rib graft

Four questions the published evidence supports asking, and what the literature says the answer should sound like.

Will you use my own rib or donated rib, and if donated, how was it processed?

Processing changes the risk more than the source does. A stratified meta-analysis found the autologous-versus-donated answer depends on how the allograft was prepared, and a survey of tissue banks found twelve different protocols in use, rarely stated in the outcome papers. A surgeon who uses donated rib should be able to name the bank and the processing.

Rests on: Wael Moftah et al., stratified meta-analysis · Vasudev et al., allograft processing.

Where will the chest incision go, and what will the scar look like?

Hypertrophic scarring is the commonest donor-site complication in the largest pooled series, 491 patients. The answer should name the incision site and the expected scar, not just say the scar is hidden.

Rests on: Wee et al., 491 patients.

Should I have a chest CT first?

Worth raising if the patient is over about 50, when costal cartilage calcification makes carving harder and warping more likely. Calcification reaches 89.6% in adults in the imaging series.

Rests on: the calcification series.

What happens if the graft warps, and who pays for the correction?

Warping is the graft's known price and there is no head-to-head trial of the carving methods that resist it. The answer that matters is the practice's revision policy in writing. See what rhinoplasty costs.

The national guideline

The American Academy of Otolaryngology publishes a clinical practice guideline on nasal form and function after rhinoplasty, with a plain language summary written for patients. It sets what a surgeon should assess and record before operating, whatever the graft material is going to be.

The surgeons' own textbook chapters

Rhinoplasty Archive, the free online rhinoplasty textbook edited by Daniel G. Becker, carries chapters on rib grafting and on the alternatives to a solid carved graft. They are written for surgeons and go further into technique than a patient page should.

The reference summary

Rhinoplasty in StatPearls, on the National Library of Medicine's Bookshelf, gives the anatomy, the graft sources and the complication list in full text at no charge.

The regulator

Donated rib is human tissue, and the bank that supplies it is regulated by the US Food and Drug Administration. The federal databases are open to anyone. The tissue and tissue products pages set out what the rules cover, the establishment registration query lists the banks by name, and clearances for a manufactured implant used alongside cartilage sit in the medical device databases.

What is not settled

  • Autologous against donated rib is unresolved: one cohort found four-fold higher revision odds with cadaveric rib, another found them equivalent, and a stratified meta-analysis says the answer depends on processing. No randomised trial exists. [40147429, 38502836, 42681592]
  • Processing is not standardised, twelve protocols across 41 tissue banks, rarely stated in outcome papers. [42464436]
  • Reported revision rates after autologous rib range from 2.25% to 14.07% across pooled analyses of overlapping literature, because "revision" is defined differently in each. [36071242, 25429595]
  • Which carving method best resists warping has no head-to-head trial; the alternatives are described, not compared. [36656674, 35748855]
  • Almost every technique paper is a single surgeon's consecutive series.
