The clinical pathology of middle ear cholesteatoma were classified from the surgical findings. And the surgical results were studied in each classified groups in order to evaluate the surgical techniques used in our clinic.
The cases analyzed were 73 ears operated on from 1985 and 1989. They consisted of 30 ears of pars flaccida type (attic type), 23 ears of pars tensa type (adhesive type) and 20 ears of the recurrent cases.
The conclusions obtained were as follows:
1. The extent of cholesteatoma was graded into 4 stages in the flaccida type and tensa type, which were seemed proper and useful to analyze the results of surgery.
2. For treatment of the pars flaccida type, the anterior tympanotomy is absolutely necessary although the obliterative technic is not necessary. There were no cases of recurrence in this group.
3. For treatment of the pars tensa type, transcanal atticotomy, lateral tympanotomy in combination with anterior tympanotomy were absolutely necessary, and in the extensive cases antrotomy, mastoidotomy and further obliterative technic were necessary.
4. Two cases of recurrence were found in the pars tensa type. They included each one of grade II and grade III cases, using canal-up technique combined with anterior tympanotomy and posterior tympanotomy.
