Aim:

The aim of this study was to determine the causative pathogens and the antibiotics to which they are susceptible in order to plan effective treatment in patients with chronic otitis resistant to treatment.

Materials and Methods:

A total of 465 patients with chronic otitis who were admitted to the otorhinolaryngology clinic of Keşan Hospital (Edirne) after receiving treatment in at least one different epicenter between April 2013 – July 2018 were included in this study. Patients with predisposing factors (allergy, cleft lip and palate, immune suppression), diffuse polyposis in the middle ear, or cholesteatoma were excluded from the study. Physical examination and culture and antibiogram results were evaluated.

Results:

211 (45.4%) of the patients were female and 254 (54.6%) were male. The mean age of the participants was 49.7 ± 17.3 years. The most frequently isolated bacteria were the Pseudomonas genus in 36.6% (n = 170) of patients. The second most common bacterial genus was Staphylococcus, found in 23.4% (n = 109) of patients. Pseudomonas bacteria were most susceptible to Ceftazidime (97.6%), Ciprofloxacin (93.5%) and Gentamycin (92.4%).

Conclusion:

Pseudomonas was the most commonly isolated bacterial genus. Accurate detection of the causative microorganism and determination of antibiotic susceptibility will contribute to the prevention of both complications and development of new infection by enabling the selection of correct antibiotics for treatment.
