title: [Annular wedge tympanoplasty: a variation of overlay myringoplasty].
abstract: Myringoplasty has been increasingly refined in recent years and today the most frequently employed are the "overlay", the "underlay" and the "interlay". Of these the overlay technique appears to best guarantee graft stability. However, with this technique there is the risk of blunting and neotympanum lateralization which can compromise functional recovery. To obviate these drawbacks, the authors propose a modification of the classical overlay technique. This modification consists of detachment of the anterior portion of the Gerlach annulus and the adjacent protympanum mucosa in order to insert the graft between the bony and fibrous portions of the annulus. This technique is defined as the "Annular Wedge Tympanoplasty" (AWT). From January 1993 to July 1994 a total of 74 tympanoplasties were performed using the AWT technique to reconstruct the tympanic membrane. In 71 (96%) of these, the opening closed completely. As regards incomplete healing, 2 cases showed signs of blunting, 3 showed posterior lateralization and 1 full lateralization with a reduction in the hearing level recovery. The work is not conclusive although it does present a technique which is easy to perform and which provides good functional recovery.
