The Recurrence Rate of Pars Tensa Retraction Cholesteatoma and a New Staging System
نویسندگان
چکیده
Objective: To 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.

Staging and classification criteria for middle ear cholesteatoma proposed by the Japan Otological Society.
In order to provide a basis for meaningful exchange of information among those treating cholesteatoma, the Committee on Nomenclature of the Japan Otological Society (JOS) was appointed in 2004 to create a cholesteatoma staging system as simple as possible to use in clinical practice in Japan. Following the announcement of preliminary criteria for the staging of pars flaccida (attic) cholesteato...

Seventy-three cases of adult cholesteatoma, including 52 cases with pars flaccida type cholesteatoma and 21 with pars tensa type cholesteatoma, were examined using high resolution computed tomography, in both axial (lateral semicircular canal plane) and coronal sections (cochlear, vestibular and antral plane). These cases were classified into two subtypes according with the presence of extensio...
متن کاملStudy of Correlation of Pre-Operative Findings with Intra-Operative Ossicular Status in Patients with Chronic Otitis Media
Introduction: Chronic otitis media (COM) has been broadly classified into mucosal and squamous subtypes. COM types are associated with erosion of the ossicular chain. The aim of the present study was to correlate the type of COM, the site of perforation/retraction, and the type of disease pathology with the pattern and degree of ossicular chain necrosis. Materials and Methods: A prospecti...

Background: During last decades, many otologists attempted to make a long standing dry ear, resulting in better hearing after cholesteatoma surgery. This study evaluated the prognosis of two common methods of cholesteatoma ear surgery considering ten years follow-up. Methods: This retrospective analysis was done using medical records of 108 adult patients with cholesteatoma. After ten years of ...
