Between 1973 and 1977 135 otoplasties were performed following the technique described by Mustardé in 1963. The follow up covered 105 of the cases (77,7%). The quality of the results and the validity of subjective and objective criteria for evaluation were evaluated statistically and compared with previous data. Three aesthetic groups were described by statistical methods. Shape and position of the corrected auricle were classified as good (53%), improved (35%), almost unchanged (12%), partial relapses 8 (7,5%), total relapses 6 (5,7%). In no case was a deteriostation observed. The head-pinna distance was measured at different points and compared with a normal sample. Calculating the head-pinna angle we found the normal range in only 33% (28 to 35 degrees), 40% were not symmetrical and in 39% an over-corrected or a moon-ear was seen, but patient and parents considered the latter cases pleasing. The influence of ear thickness on the result of the operation was investigated. In all failures (12%) the cartilage was thicker than 3,1 mm. in the triangular fossa and 3,4 mm. in the cavum. Since Mustardé's (1963) procedure is a suturing technique it is contraindicated in cases of macrotia. Experienced surgeons achieved better configuration of the antihelix and superior crus but were also responsible for 97% of the over-corrections.
