investigate the cumulative recurrence rate of pars tensa retraction
cholesteatoma on the new staging system established by Japan Otological Society
(JOS). Materials and
Methods: It is a retrospective study and performed in a tertiary and academic
center. The series comprised 71 patients with pars tensa retraction cholesteatoma
who underwent surgical treatment by a single surgeon between 1994 and 2007.
Results: The 10-year cumulative recurrence rate of pars tensa retraction
cholesteatoma was 12.1% overall, 20.0% in Stage I, 14.4% in Stage II and 6.2%
in Stage III. Conclusions:
The JOS staging system for pars tensa retraction cholesteatoma did not reflect
the prognosis. The development of a common international staging system for
cholesteatoma in the future is desirable.
