Lack of healing or continued meatal discharge suggests that some infected
cells may have been missed, or that spicules of infected bone have been left
in the cavity, and in either case the wound may have to be re-opened. It
may be that some contributing factor, such as infected adenoids, is still
present, and in many instances the adenoids may be removed under the
same anaesthetic as is used for the first dressing.
The Schwartze operation results in the cure of the discharge in 90 per cent
of cases, and in the return of normal hearing in 70 per cent.
