Objective To discuss the surgical technique in the treatment of cholesteatomatous otitis media. Methods Fifty six ears underwent mastoidotympanoplasty with epitympanoplasty in our hospital from November 2009 to July 2010. This technique include mastoidectomy with canal wall up, epitympanoplasty with cartilage obliteration and hearing reconstruction. This paper report and discuss the related technique. Results All cases were followed up 1-9 months. One cases had to received revision operation because of ear pain 3 months after the first operation. Two cases had the residual perforation of tympanic membrane because of healing worse and another two cases had perforation again after operation in the posterosuperior ear dream. The rest cases healed well within one months. 26 cases of 56 had the whole hearing document with the average AB gap of 0.5, 1, 2 kHz shorting from 31.9 dBHL to 19.6 dB HL. Conclusion The mastoidectomy with canal wall up accompanied by epitympanoplasty with cartilage obliteration simplified the classical technique of CAT. The healing time was shortened greatly because of the preserved canal wall. The cartilage obliteration in the attic can prevent the forming of the abstraction pocket effectively and the recurrence of cholesteatoma. This technique provides another selection of treating otitis media for otologist.
