ACOSTA, Silvana; LAGOS, Carolina  y  YANEZ, Ricardo. Evaluation of donor site in auricular reconstruction of microtia with supraperichondrial costal cartilage harvest technique. Rev Chil Cir [online]. 2016, vol.68, n.2, pp.131-136. ISSN 0718-4026.  http://dx.doi.org/10.4067/S0718-40262016000200004.

Aim: To assess the presence of donor site sequel of patients undergoing ear reconstruction with costal cartilage harvest, using supraperichondrial technique. methods: Cross-sectional study; patients under 15 years. The cartilages were harvested with perichondrium. Three observers performed donor site assessment; they were independent to this study (validated Strasser score: deformity, asymmetry, contour and scar). Children and their mothers were applied satisfaction survey. Analysis of the association between variables: nonparametric tests. Results: 19 reconstructions, 18 patients, age 8 (6-15) years, follow-up 50 (14-96) months; number of rib cartilage harvested 3 (2-4) units. Expert assessment: excellent in 2 (10.5%) cases, good in 10 (52.6%), regular in 7 (36.8%). Most mothers and patients rated the result as good. There was no significant difference in the score, with respect to the number of harvested costal cartilages. To separate them by age, poorer results were obtained at surgery before 10 years of age than in older (p < 0.03). Conclusion: Ear reconstruction and supraperichondrial technique for costal cartilage allows obtain good results in donor site. There is high satisfaction when evaluated by the patient and his mother, as well as observers. The result is not dependent on the number of harvested cartilage, but is related to age at surgery, best results were obtained in patients operated over 10 years of age.
