Comparison of Local and Systemic Ciprofloxacin Ototoxicity in the Treatment of Chronic Media Otitis

INTRODUCTION: Chronic media otitis is a common cause of reference to ear, nose and throat clinics and the treatment is one of the health problems among ENT specialists. Ciprofloxacin drop that is of fluoroquinolone drug class due to good treatment effect is now widely used in the treatment of chronic media otitis. Due to the widespread use, it seems proper research on the human population has not been taken to ensure its non-toxicity in the inner ear, therefore comparison of local ciprofloxacin ototoxicity with systemic in chronic media otitis is investigated in this study. MATERIALS AND METHODS: This study was conducted as a randomized clinical trial. Prospective methods were considered and the number of samples in the study group was 40 patients that were treated with ciprofloxacin drops. And in the control group 32 patients with chronic media otitis who were treated with ciprofloxacin tablets. The collected data was analyzed using SPSS software. RESULTS: Statistical indicators of different frequencies in air conduction (AC) in both groups showed, there was significant improvement in hearing thresholds at frequencies of 250, 8000, 1000 in air conduction for the group receiving drops compared to the group receiving tablet. Based on statistical indicators in different frequencies of bone conduction in the two treated groups, there was significant difference in the two groups receiving tablets and drops only at a frequency of 4000Hz that drop impact improves hearing threshold and in contrast in the group receiving tablet hearing loss was seen in the frequency of 4000. DISCUSSION: Topical ciprofloxacin is a safe and uncomplicated ototoxic drug that is an effective antibiotic used in the treatment of refractory chronic otitis those dregs such as pseudomonas aerogenusa and staphylococci resistant to methicillin are responsible for it, which in the usual doses has not harmful effects on hearing hairy cells.
