Abstract

IMPORTANCE: Auricular reconstruction is a unique blend of cosmesis and functionality. The choice of the optimal framework material to use is an important decision for the patient with microtia. OBJECTIVE: To evaluate and compare the outcomes of reconstruction of microtia using porous polyethylene implants and rib cartilage grafts. DESIGN, SETTING, AND PARTICIPANTS: Retrospective medical record review from January 1, 2001, through December 31, 2012, at a tertiary academic institution. Thirty-five patients (36 ears) undergoing microtia repair were divided into groups using high-density porous polyethylene (17 ears), rib cartilage (17 ears), and both materials (2 ears). Only patients with completed repair were included in the analysis. EXPOSURES: Reconstructive surgery for microtia. MAIN OUTCOME AND MEASURES: We compared groups in terms of mean number of operations, age at treatment initiation, and complications (infection, extrusion, cartilage exposure, and pneumothorax). Photographs were graded by blinded observers to give each patient a score on protrusion, definition, shape, size, location, and color match. RESULTS: The cartilage group was older than the polyethylene group (mean age, 8.0 vs 6.9 years; P = .23). The mean number of operations was 4.88 for the cartilage group vs 3.35 for the polyethylene group (P = .004). Two patients in the polyethylene group had postoperative infections and implant extrusion and underwent subsequent reconstruction with cartilage grafts. Patients in the cartilage group had no infection or extrusion; 1 had a minor cartilage exposure. No patient had pneumothorax. Patients in the polyethylene group had significantly better grades for ear definition and size match, whereas those in the cartilage group had a significantly better color match. Patients in the cartilage group had better protrusion and location outcomes, although the difference was not significant. CONCLUSIONS AND RELEVANCE: Comparison of reconstruction with porous polyethylene implants and rib cartilage grafts showed neither material to be clearly superior. Polyethylene implants may achieve a better cosmetic outcome in the categories of ear definition, shape, and size with a higher risk for infection and extrusion. Patients in the cartilage group were older and underwent significantly more surgical procedures, which should factor into the decision on which technique to choose. LEVEL OF EVIDENCE: 3.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
