Abstract:
Objective To report the curative effect of the epitympanoplasty with cartilage obliteration in the treatment of middle ear cholesteatoma .Methods This study retrospectively analysed 123 cases ,with middle ear cholesteatoma treated in our department from November 2009 to July 2012 .The operation included mastoidectomy with posterior canal wall preserved ,lateral wall of attic resected ,facial recess opened to the epitympanum ,epitym-panum obliterated with cartilage and mastoid cavity blocked with bone dust .All cases were followed up on complica-tions and hearing improvement .Results All cases were followed up 6~38 months .In 123 cases ,there were 2 ca-ses had cholesteatoma recurrence in the middle ear cavity ,6 cases had infection of post auricular incision after opera-tion ,3 cases had residual marginal tympanic membrane perforation ,2 cases had ossicular replacement prosthesis ex-clusion ,and 6 cases had canal wall skin swelling or defect .The rest cases acquired full -recovery after 2 or 3 wound dressing changes .Out of 123 cases ,83 cases had the whole hearing document ,the average AB gap at 0 .5 ,1 ,2 kHz reduced from 32 .2 ± 11 .2 dB pre-operation to 20 .7 ± 12 .4 dB post -operation .The AB gap of pre - and post -operation had significant difference (P<0 .001) .Conclusion The mastoidectomy with posterior canal wall preserved greatly shortened the healing time .The resection of lateral wall of epitympanum can exposed operating field more completely and remove lesions thoroughly .The cartilage obliteration in the attic can prevent the retraction pocket formation effectively .This technique provides alternative in treating middle ear cholesteatoma .
