ABSTRACT

Background: The closing techniques or reconstruction of the tympanic membrane perforations were described in 19^th century. In 1952 Wullstein and Zollner established the principles of tympanoplasty. At present times, temporary fascia is the graft material most frequently used, in 90% of the reported cases. The tympanoplasty “under” technique has reported closing rates in 83% of the series. The “interlayers” technique consists of the positioning of conventional graft between the tympanic membrane layers, this means placing it between the mucous and the fibroepitelial layer using any kind of technique.
Objectives: To present the “interlayers” tympanoplasty as an alternative technique for the reconstruction of the tympanic membrane and to establish it as a technical option for the repair of the perforated tympanic membrane.
Material and methods: Thirty patients were operated by “interlayers” tympanoplasty and 30 by “under” tympanoplasty verifying if there was or not integration of the graft after three months, as well as the result of audiometric rank.
Results: Three months after the timpanoplasty surgery in the “interlayers” group 96% of the patients present a complete graft, as well as 80% of patients operated by “under” technique.
Conclusions: The “interlayers” tympanoplasty technique is an effective and versatile tool in the reconstruction of the tympanic membrane, and well done diminishes the risk for nonintegration of the graft.
