BACKGROUND Canal wall down and canal wall up mastoidectomy represent two surgical approaches to middle ear cleft pathology. Much literature has been devoted to the merits and demerits of these two procedures. In terms of eradication of disease and hearing improvement, a prospective analytical study is done on canal wall up and canal wall down techniques in atticoantral type of CSOM.
MATERIALS AND METHODS
The study was carried out at Government ENT Hospital, Visakhapatnam, from June 2016 to June 2017. A total number of 250 patients with atticoantral variety of CSOM were included in the study and subjected to surgical treatment by canal wall up or canal wall down mastoidectomy along with tympanoplasty.
Results were analysed in terms of condition of cavity, condition of graft and gain in hearing. In patients who underwent canal wall up tympanomastoidectomy, there were 91.3% of graft take up and also improvement in hearing. In patients who underwent canal wall down tympanomastoidectomy, the outcome was excellent with 93.49% graft take up and 92.68% restoration of hearing.
Although, the statistical evidence of success is almost similar in both the procedures, yet canal wall down procedure provides maximum benefit to patients with low socioeconomic status and poor follow up in terms of eradication of disease and hearing improvement.
