| | Abstract | Some modified surgical techniques are described for constructing a deep conchal cavity and pseudomeatus and obtaining high auricular projection in congenital microtia. At the primary operation, a rather small portion of the microtic vestige is utilized for the lobule by switching, sparing the skin for the concha, with no free skin graft used. For higher projection of the auricle, three-dimensional transposition of a retroinfraauricular flap together with cartilage pieces underneath is applied to the cephaloauricular sulcus. A deep conchal cavity is constructed by further removal of the soft tissue there, transplantation of a cartilage for building a high posterior wall of the concha. The external meatus is successfully imitated by transplantation of a cone-shaped composite graft taken from the cymba of the opposite ear. The retroinfraauricular flap, the reconstruction of a deep concha, and the composite graft technique were successfully used in 55, 16, and 11 ears, respectively. | | Language | eng | | Pub Type(s) | Journal Article
