CANATA, Carlos Mena et al. Evolution of the canal wall down mastoidectomy in patients with chronically cholesteatomatous otitis media . An. Fac. Cienc. Méd. (Asunción) [online]. 2008, vol.41, n.3, pp.18-22. ISSN 1816-8949.

In an observational, descriptive and retrospective study of the cross-section applied to the patients treated at the Chair Otolaryngology (Room 9) of the Clinical Hospital in Asunción from the 1st of January 2003 until the 31st of December 2007. A total of 57 patients were treated performing radical mastoidectomy, after a cadre of chronically cholesteatomatous otitis media, during the years 2003(10); 2004(12); 2005(10); 2006(18); 2007(7) and so on. From this group of patients recorded in the mentioned statistics, most of them were male gender (67.67%) from 0 and 20 years old (64.9%) residents in the Central State of the country. 25 of the 57 cases evaluated reported a prevalent fetid suppuration of the left ear (37,5%). Most f the audiometric records performed to these patients reveal unilateral moderate conductive hypoacusis of the left side (51.11%). In the postsurgical evolution during the first month, granulation tissue in the radical cavity was mostly found(48%); after six months, the presence of dry ear with abundant peeling (81,08%) and finally, after 12 months, the radical cavity is mostly dry in a 46,87%, showing an important evolution.
