Abstract：Objective To investigate the fungal spectrum,disease features and targeted therapy of ear canal fungus dis-ease in the elderly . Methods The identification methods follow as fungal smear microscopy observation and culture isolated. Staining with eosinophils and mast cells.According to the therapy of ear clean unobstructed ,topical antimycotic drugs using and antianaphylaxis treatment targeted. Results From 2006 to 2011,86 patients with 112 ears who met ear canal fungus dis-ease in the elderly with the age between 60 and 85 were collected;46 cases were males(53.49%),40 cases were fe-male(46.51%), average age was 72.The fungal culture of 90 ears in the 112 ears who met ear canal fungus disease was positive, positive rate was 80.36%.Aspergillus species was the most common fungus which had 64 ears(71.11%),Secondly for the candi-da infection,which had 13 ears(14.44%).After a month of treatment and follow-up,84 ears were cured(75%);22 ears were ef-fective(19.64%);6 ears were invalid(5.36%). The total effective rate was96.64%. Conclusions The characteristic of ear ca-nal fungus disease in the elderly:Aspergillus species are the major fungus;anatomic abnormality of ear canal,the slower speed of outward migration velocity of eardrum and ear canal epidermis ,hair abnormal proliferation of ear canal,foreign bod-ies of ear canal,all of these are its unique causes.anaphylaxis caused by fungus is one important pathogenic mechanism.ear clean unobstructed , antimycotic drugs using and antianaphylaxis treatment are the equally important steps to treat ear canal fungus disease in the elderly targeted.
