There have been many methods presented for the closure of a persistent postauricular fistula following an operation on the mastoid. Some of these methods accomplish the closure of the defect in the skin but bridge over the deeper portion of the fistula, leaving a cavity, which may fill with secretion and cause the fistula to reopen. If the cavity can be obliterated completely and the skin closed tightly over it, it is more probable that healing will be complete. In order to accomplish this, Eagleton1 filled the cavity with chips of bone and suggested the use of fat, Straatsma and Peer2 used a free fat graft and Almour3 employed a pedunculated flap from the temporal muscle.
In 4 cases we have used a method which has each time been successful and which may be recommended for its simplicity.
