Measure
Dornase Alfa (Pulmozyme®)
dornase alfa (Pulmozyme®): This study will compare two treatment arms. Patients will be randomized to either traditional treatment (Ofloxin)or to experimental treatment \[dornase alfa (Pulmozyme®)\]. Each arm will have subjects instilling 5 drops twice daily for 7 days to the affected ear.
Ofloxin
dornase alfa (Pulmozyme®): This study will compare two treatment arms. Patients will be randomized to either traditional treatment (Ofloxin)or to experimental treatment \[dornase alfa (Pulmozyme®)\]. Each arm will have subjects instilling 5 drops twice daily for 7 days to the affected ear.

PRIMARY outcome

Timeframe: 14 days

Population: Analysis performed on ear level. Some participants received drops in both ears and thus both ears were included in analysis.
