In cholesteatoma surgery, we use open tympanoplasty and expose the matrix to the open cavity in cases with adhesion of matrix in which the dura is too tight to exfoliate. We applied this method to four patients with firm adhesion of matrix and dura. All four exhibited poor mastoid development. Three exhibited adhesion to the dura of the middle fossa, while two exhibited adhesion to the dura of the posterior fossa. Labyrinthine fistula in the posterior semicircular canal was found in two of these patients. Our findings suggest that firm adhesion of matrix and dura may be caused by isolation of cholesteatoma and continuous inflammation. Our patients experienced no complications, and we therefore recommend this method for patients with firm adhesion of matrix and dura.
