  • Title: [Complete obliteration of the mastoid apophysis with an artificial material. A concept for the prevention of the recurrence of cholesteatoma].
    Author: Meuser W.
    Journal: Laryngol Rhinol Otol (Stuttg); 1982 Oct; 61(10):560-4. PubMed ID: 7144385.
    Abstract:
    Recurrences of cholesteatoma may occur, following closed operation techniques, if retraction pockets or matrix inadvertently left in the tympanic space invade the exenterated mastoid cavity. The precondition for such recurrence is the existence of the exenterated cavities, which serve as "nesting sites" for the matrix or the retraction pockets. These recurrences can be avoided by obliterating the mastoid cavity behind a reconstructed posterior ear canal wall with a non-resorbable material (plastic bone cement) and by uniting the lateral part of the attic with the outer ear canal. This will definitely prevent the exenterated spaces from the being invaded by any recurrence. The operation technique is described.
