We reported our experiences of surgical auricle formation for microtia using silicone rubber, produced by Ko-Ken, on 15 cases in the period covering the years 1975 to 1979.The operation was done in the same procedure for the costocartilage frame method.The whole operation procedure consists of three stages, the first stage being the posterior and downward turning of the existing lobule of the ear, formation of a subcutaneal pocket, inserting of the silicone rubber frame into the subcutaneal pocket, and thus the present method performs the external auditory meatus simultaneously. The second stage operation consists of decollement of the lower half of the inserted silicone rubber frame from the pars temporalis and raise it in the so-called manner of "raising the ear" and skin grafting all over the raw surfaces. The third stage operation consists of decollement of the remaining upper half of the silicone rubber frame to fix it upward, and the full thickness skin grafting on the exposed raw surface. Besides the above, a few times of trimming of various parts of auricle are done.Operations of the above method have been completed on 12 cases. Both the surgeons and the patients are particularly satisfied in 4 cases. The surgeons are sufficiently satisfied while patients are fairly satisfied in another 4 cases, and both the surgeons and the patients are not quite satisfied in 2 cases, and both the surgeons and patients are utterly unsatisfied in 2 other cases.In view of the experiences of the above operations, we conclude that this operation method is relatively simple to perform and the lobule thus formed has soft texture just like natural one while it has disadvantages such as exposition to secondary infections or external injuries or perfrigeration which require exquisite precautions. However, these difficulties can be conquored with sufficient caution, and we are in favor of this method if this is to be employed side by side with the costocartilage frame method in the future.
