The histological appearances of the lesions were typical inflammatory granuloma. Little allotype cell were found in one histologic sample. Fifteen cases received surgical excision and the recurrence rate was 60% after operation. Recidivist received operation again,4 cases among these cases received antireflux therapy after operation but 3 cases recurrences again. Among those follow-up cases(3 cases), 1 case was self-cure and other 2 cases appeared no marked change during observation period.

Conclusion: Laryngeal contact granuloma predilected the middle-aged male. The localization and appearance of the granuloma is very characteristic.
