Non-specific granuloma of the larynx is relatively rare, and its pathogenesis has not been clarified yet.Some authors reported that the laryngeal granuloma might be caused by inflammatory change in the posterior wall of the larynx, which often happens after excessive vocal use, cough, throat cleaning, or tracheal intubation.In our clinic, we had treated 105 cases of the granuloma from April, 1965 to December, 1986. On those 105 cases, a statistical study has been carried out to clarify the pathogenesis and to obtain the recurrence rate.Seventy six cases were male and average age was 48.39±13.00. Twenty-nine cases were female and average age was 39.34±15.64. The most frequent complaint was hoarse voice, observed in 79 cases. In male cases, non-specific granuloma was 85.5% (65 of 76 cases). On the other hand, in female, it was 51.7% (15 of 29 cases). And the difference between male and female was statistically significant. In female, intubation granuloma was 48.3% (14 of 29 cases), and in male, 11.8% (9 of 76 cases). This difference was statistically significant.Seventy nine cases have been surgically treated, and 15 cases have been treated with CO2 laser. No apparent difference among different types of therapeutic methods in recurrence rate was statistically observed. Non-specific granuloma tends to recur more frequently than intubation granuloma does. The recurrence rate of the former was 51.7% and the later 21.4%.
