Single-field reconstruction of congenital longitudinal cleft earlobes using large Z-plasty and dermofat grafting

Congenital longitudinal cleft earlobes (CLCEs) present a ginkgo leaf–shaped malformation with combined skin and soft-tissue deficiency along the inferior margin. No previous method has addressed both deficiencies while preserving earlobe length and contour. We introduce a simple, single-field procedure that combines a large, single Z-plasty for complete skin preservation with dermofat grafting for volumetric restoration. A Z-plasty was designed on the cleft-side skin, with the central limb placed along the cleft valley and the opposing limbs aligned with the anterior and posterior ridges of both lobules. After elevating both triangular flaps and fully releasing the contracted fibrotic tissue at the cleft base, a compact, dense dermofat graft harvested from the ipsilateral mastoid area was inserted into the inferior marginal defect and anchored to prevent superior migration. The Z-plasty flaps were then transposed and closed without skin sacrifice. Postoperatively, the superior portion of the earlobe was compressed to prevent graft displacement. At 16–32 months of follow-up, all reconstructed earlobes maintained stable volume and natural contour without horizontal or vertical shortening. This combined technique provides a reliable, tissue-preserving, and cosmetically favorable option for correcting CLCEs, effectively resolving both skin and soft-tissue deficiencies within a single operative field.
