[Tympanoplasty and Sourdille].

In his article published earlier in 1929, Maurice Sourdille proposed two innovations in middle ear surgery: the tympanomeatal flap and surgery of chronic otitis. Those events were not only the starting point of a new era of modern tympanoplasty but also led to the way to the development of middle ear exploration with purposeful resection of the tympanic framework for accessing to the windows and for sealing a perforated tympanic membrane.
