Complications in Functional Rhinoplasty Related to Cartilage Graft Source

Overview

Functional rhinoplasty often needs cartilage for structural grafts. The authors reviewed patients treated from 2017 to 2022 with at least 6 months of follow-up, comparing autologous cartilage against fresh-frozen cadaveric rib (FFCR) on revision, infection and persistent obstruction, using chi-squared tests and multivariable logistic regression.

Sections of note

• 259 patients, mean age 43.1, 71.4% female; mean follow-up 12.3 months (range 6-54).
• 58 (22.4%) received FFCR.
• Revision: 8 of 201 (4.0%) autologous versus 7 of 58 (12.1%) FFCR; overall 5.8%.
• Persistent obstruction without surgery 6.6%; infection needing antibiotics or drainage 4.6%.
• Logistic regression: FFCR associated with revision (p = 0.024, OR 4.0), not with infection (p = 0.101) or obstruction (p = 0.187).

What it means for a patient

• Donor rib avoids a chest incision but in this study was linked to three times the revision rate.
• Infection was not higher with donor cartilage.
• If your own cartilage is insufficient, the authors advise a tailored discussion of the trade-offs.

Why this paper matters

It is a direct comparison of graft sources in a functional (not cosmetic) population, and its finding conflicts with some single-surgeon series favouring donor rib. Limits: retrospective, unequal groups, and the reported confidence interval for the odds ratio is inconsistent in the abstract.

Terms

• Functional rhinoplasty: nasal surgery to improve breathing.
• Fresh-frozen cadaveric rib (FFCR): donor rib cartilage preserved by freezing.
• Autologous cartilage: the patient's own septal, ear or rib cartilage.
• Odds ratio (OR): the relative odds of an event; 4.0 means four times the odds.
• Multivariable logistic regression: a statistical method adjusting for several factors at once.
