Abstract
Conchal defects secondary to surgical procedures or trauma often cannot be closed primarily.Tissue transfer for closure of defects must be tension free and not create a postauricular sulcus too shallow.A retroconchal island flap provides such a closure. A rhomboid transposition flap used to provide closure of the donor site retains the depth of the posterior sulcus.The closure of the defect heals well within 4-6 weeks even in presence of scar tissue from multiple prior surgeries.The retronconchal island flap is a simple, reliable technique to close the defect of the concha without sacrificing the natural depth of the posterior sulcus.
