Clinical course of laryngeal granuloma without surgical treatment.

Laryngeal granuloma is a rather common pathological entity, but its therapeutic strategy is still controversial. In general, therapeutic strategy consists of medications such as steroids or tranilast, in addition to vocal hygiene and surgery. Surgical removal is most commonly performed. However, it has recently been reported that recurrence after surgery is high.We successfully treated 19 of 20 cases of laryngeal granuloma without surgical removal. It took 28-328 days for the granulomas to disappear. Therefore conservative treatments should be the first choice of treatment.
