Post-operative follow-up and outcomes
All patients were regularly followed-up at our outpatient department.
The local findings of post-treatment ear drum were evaluated by
otoscope. Every patient was followed at our clinic at least four months.
The definition of treatment success is no pathologic finding on ear drum
and improvement of clinical symptoms four months after the surgery. The
definition of recurrence is local finding showing granulation tissue on
ear drum again during four months to one year after surgery (Figure 1).
Any new complaint or complication were recorded on chart.
