Abstract

In microtia reconstruction, maintaining a healthy contact between the skin and the fabricated cartilage framework is essential to attaining a smooth and accentuated contour of the reconstructed auricle. Conventional means to achieve this include bolster sutures and continuous suction drains, both of which have associated shortcomings. A new dressing method was developed and applied in 10 consecutive patients who underwent the first of a two-stage microtia reconstruction using the Nagata technique. A small catheter was introduced into the space between the skin and the cartilage framework. Negative pressure was applied through the catheter, drawing the skin onto the cartilage framework. This evens out the skin, accentuates the contour of the framework and concurrently eliminates potential dead space. Skin contact on the framework is maintained whilst the catheter is removed and an occlusive transparent dressing is applied to the ear. Of the 10 cases in which this manoeuvre was performed, one had to be converted to the bolster suture technique due to a persistent air leak from the wound. Overall results of the nine cases in which this technique was carried out successfully demonstrate smooth skin contour and excellent definition of the fabricated framework. This negative pressure manoeuvre provides a simple, safe and consistent approach to achieving a smooth and accentuated contour in auricular reconstruction.
