The attempts for closing tympanic perforations has been a matter of concern between the otologists since past times. BANZER, in 1640, tried to seal them with pork bladder; YEARSLEY, in 1850, was the first to use a fragment of cotton wool to patch them up; BERTHOLD, in 1878, used skin grafts; and BLAKE, in 1887, did the same with papier patches. From 1950 onwards, owing to the spreading of optical devices, the utilization of several materials become generalized. Although independently of the followed technique high rates of closures were recorded, it seems advisable to stablish a procedure joining good results and the easiness of placement of the piece and, specially, to avoid the general anesthesia. In our Department the butterfly-like method of myringoplasties is practised in certain cases. The procedure is based in that of STROUD. The results are not better as those gained through classics but it is worth because of the advantages of application and the accuracy of placement.
