BACKGROUND Several methods have been developed to prevent or correct dog-ears. Most of these methods, however, result in prolonged scars and operative times.
OBJECTIVE We observed dog-ears without correction to examine the regression of dog-ears with time.
METHODS The study was performed on 43 cases of dog-ears in 26 patients. Linear regression analysis was performed to examine the correlation between various factors and the height of the dog-ears (%). We produced a regression equation to allow prediction of the height of the dog-ears (%). In addition, we estimated the initial height of the dog-ears that should be removed during surgery.
RESULTS The height of dog-ears regressed with time, and this response was better in younger and female patients. It was predicted that the time taken for a dog-ear to reduce to 50% of its original height was 20.697 days; the median time at which dog-ears completely regressed was 132 days. The odds of regression of dog-ears with an initial height of r8mm was 4.667 times greater than that of larger dogears.
CONCLUSIONS If the height of a dog-ear is r8mm, we recommend observation rather than immediate surgical removal.
