Thermosensitivity in a reconstructed microtic ear.
Abstract
The aim of this study was to evaluate thermo-thresholds in autologous reconstructed microtic ears. Nineteen patients with unilateral microtia were investigated no less than two years after the last operation (3.6+/-1.7 years). Their normal corresponding ear acted as controls. Eight healthy children were also investigated to illustrate technical differences between measuring the two sides. Thermal sensitivity was tested quantitatively using a SENSELab MSA Thermotest. The skin temperature was also tested. Three different areas of the ear were examined: the lobe, the antihelix, and the helix. The reconstructed ear had a significantly higher skin temperature for all investigated areas compared with the normal ear (reconstructed ear 30.2+/-1.2 degrees C, normal ear 28.6+/-0.9 degrees C). For the controls there were no significant differences in any area. For the patients there were small differences in perception of cold between the reconstructed and the normal ear. There were significant differences in the antihelix region and the helix in heat perception in the reconstructed ear compared with the normal one (helix reconstructed ear 43.9+/-3.8 degrees C, helix normal ear 38.3+/-3.0 degrees C, antihelix reconstructed ear 39.9+/-3.0 degrees C, antihelix normal ear 36.4+/-1.7 degrees C). The reconstructed ear had a changed thermosensitivity, but there did not seem to be any clinical disadvantages.

Oberg et al found that the antihelix and helix of reconstructed ears had significantly lower heat sensitivity and were more likely than other areas to experience decreased sensation.

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.
