Antibiogram guided optimized medical treatment in chronic otitis media: A useful interventional strategy before surgery?
Abstract
BACKGROUND: Chronic otitis media is a middle ear cleft disease presenting with tympanic membrane perforation and discharge. Wet ear after tympanoplasty and discharging mastoid cavity are problematic in clinical practice.
MATERIAL AND METHODS: 1050 patients of age 10 to 50 years presenting with active ear discharge and clinically diagnosed with unilateral chronic suppurative otitis media were included in the study. The patients were equally divided into two equal groups, Group ET, and AT. All patients were prescribed topical ciprofloxacin, oral levocetirizine 5 mg and n-acetyl cysteine 600 mg BD for one week. Swabs of ear discharge were collected in ET groups for antibiogram. Both groups were evaluated on next visit and treatment changed in AT groups and result observed in next visit. Surgical outcome was evaluated at end of 2 yrs.
RESULT: A total of 1158 organisms were isolated in culture out of which, 69.94 % were aerobes, 13.47 % anaerobes and 16.58 % were fungi. On the second visit in group AT, treatment of 85.14 % patients was changed in accordance with culture sensitivity report. In patients with mucosal disease, only 46.87 % patients of group ET had a favorable outcome in comparison to 90.28 % patients of group AT while in patients with squamosal disease, 17.56 % patients of group ET and 28.99 % patients in group AT had a dry ear. Surgeries in AT group were found to have statistically significant higher success rate as compared to ET group.
