OBJECTIVE: To present our clinical experience in using two skin soft-tissue expanders implanted superposingly in the mastoid region and Medpor ear framework for congenital microtia reconstruction.
METHODS AND MATERIALS: The process of our technique is divided into three stages. In the first surgical stage, a 50 cm(3) and 80 cm(3) kidney-shaped expander is implanted under the fatty layer in mastoid region. Overlay the big expander on the small one. After the first surgery stage they are inflated alternately. In the second surgical stage, we remove two skin soft-tissue expanders and fix the Medpor ear framework to the fascial tissue which is covered by the expanded skin flap wholly without application of fascial flap. In the third stage, we perform the transposition of the auricular lobule to the designated position, construction of the tragus and refinement the new reconstructed ear. From January 2009 to December 2010, 27 patients were treated by this method of total ear reconstruction.
RESULTS: 27 patients acquired symmetrical, subtle contour, prominent reconstructed auricles. The new reconstructed ear had a good contour and its skin color and texture were nearly the same as the normal surrounding skin. The postauricular sulcus was stable and satisfactory. The postoperative follow-up time ranged from 1 to 3 years. The expanded skin flap took well without necrosis. Exposure of the skin expander occurred in 2 patients (7.4%). The Medpor ear framework was extrused in one patient (3.7%). In addition, the hematoma was observed in 3 patients (11.1%). No other severe complications happened.
CONCLUSION: Overlying implantation of two skin-soft skin expanders solves the problem of insufficient amount of the skin flap, avoids postauricular skin grafting, simplifies the surgical procedure and shortens the operation time significantly.
