Can recurrent cholesteatoma be avoided?

    Summary

    Removing the bony annulus during cholesteatoma surgery prevents recurrences. A new endaural technique creates an open cavity, avoiding dangerous epithelial retractions and leading to favorable outcomes.

    Clinical otolaryngology and allied sciences·1981

    Area of Science:

    • Otolaryngology
    • Surgical Innovation
    • Cholesteatoma Research

    Background:

    • Recurrences of cholesteatoma after surgery are often due to squamous epithelium retraction under the bony annulus.
    • This retraction can lead to the spread of cholesteatoma into the attic or mastoid cavity.
    • Avoiding bony annulus retractions is crucial for preventing cholesteatoma recurrence.

    Purpose of the Study:

    • To describe a novel endaural operation technique for cholesteatoma surgery.
    • To present a method for reconstructing the posterior ear canal wall and tympanic membrane.
    • To evaluate the efficacy of this technique in preventing cholesteatoma recurrence.

    Main Methods:

    • An endaural approach involving complete removal of the superior and posterior bony ear canal wall.
    • Reconstruction of the posterior wall using a meatal skin flap.
    • Repositioning of the posterior cutaneous ear canal wall and tympanic membrane grafting with fascia to incorporate the attic into the ear canal.

    Main Results:

    • The technique resulted in an open cavity in 67 out of 112 patients (59.8%).
    • These open cavities did not cause serious problems.
    • The described method effectively prevents cholesteatoma recurrence by creating an accessible open cavity instead of allowing epithelial retraction.

    Conclusions:

    • The described endaural technique, by removing the bony annulus and creating an open cavity, effectively prevents cholesteatoma recurrence.
    • This surgical approach offers a favorable outcome for restoring the sound conducting mechanism.
    • The development of an open cavity is a safe and manageable consequence of the procedure.
