[Analysis of the curative effect of intralesional steroid injection combined with acid-suppressive therapy for laryngeal contact granuloma]

Abstract

Objective: To study the efficacy of intralesional steroid injection combined with acid-suppressive therapy for laryngeal contact granuloma.

Methods: Eighty eight patients with laryngeal contact granuloma diagnosed from March 2010 to October 2014 were reviewed.Twenty-one patients took intralesional steroid injection combined with acid-suppressive therapy as experimental group (4 patients in initial treatment group, 17 patients in non-initial treatment group), other 67 patients only received acid-suppressive therapy as control group. The clinical data of these patients was analyzed.

Results: In experimental group, 15 patients were cured (71.43%) and the average cure time were (3.80±0.43) months, total injection time was 2-6 times and the median was 3 times. In control group, 50 patients were cured (74.63%) and the average cure time were (5.31±0.38) months. No any systemic and local complications were found in all the patients during the follow-up period of 6-42 months. The cure rate had no significant difference between the experimental group and control group, but the cure time in the former group was shorter than that in the latter group (Z=-2.093, P=0.036). In the experimental group, the initial treatment patients had no significant difference in cure rate and cure time compared with non initial patients (χ(2)=1.112, P=0.544; Z=0.000, P=1.000).

Conclusion: Intralesional steroid injection combined with acid-suppressive therapy can be recommended as a safe and effective alternative therapy for laryngeal contact granuloma, especially the refractory granuloma.
