The CWD method can secure a good operation field and remove the lesion easily, but it accompanies a cavity problem. The CWU method also has its shortcomings as it is difficult to eliminate cholesteatoma completely using this method. Combining the advantages of both methods, we invented a new operational method. The present study assesses the results of its use after a follow up of 55 months. Materials and MethodsFrom December of 1994 to March of 1997, epitympanoplasty with mastoid obliteration was conducted on 44 adults 42 patients. Of these, 38 cases were cholesteatomas, 2 cases adhesive otitis media and 4 cases chronic otitis media with poor E-tube function. The postoperative observation period ranged from 41 to 68 months, with the average period of 55.2 months. ResultsThere were 3 cases of residual cholesteatoma in the mastoid cavity and 3 cases in the middle ear cavity. All residual cholesteatomas in the mastoid cavity were treated with CWU, and there was no recurrent cholesteatoma or otorrhea, nor retraction pocket. ConclusionAlthough the observation period of the postoperative process was not long enough, there was no recurrence. We suggest that it is advantageous to operate on cholesteatoma using the new method. Korean J Otolaryngol 2001;44: KEY WORDSCholesteatoma Epitympanoplasty Mastoid obliteration. 476

A wider tympanic membrane and shallower tympanic cavity was made due to the expansion of the EAC and epitympanoplasty. EAC external acoustic canal. C Coronal view. Epitympanectomy (thick dashed line) was executed up to the tegmen tympani to expose the whole epitympanum. The bone paste (hatched area) was stuffed into the space between the tegmen tympani and fascia to make a superior part of new bony annulus. All bone paste was covered with the fascia to prevent adhesion to the malleus handle. Consequently, only the mesotympanum and hypotympanum of the tympanic cavity remained as a space having air ventilation. And thus there is no possibility of occurrence of the attic retraction pocket, in addition to the reduction of the air burden of the E-tube. A B Fig. 4.
