Abstract
Introduction Contact granulomas (CGs) and intubation granulomas (IGs) are known to have different
clinical manifestations despite having the same pathological features.
Objective The purpose of the present study was to analyze the treatment results for CG and
IG and to obtain clinical information.
Methods We retrospectively reviewed the medical records of patients diagnosed with vocal
process granuloma (VPG) between January 2015 and December 2018. The patient's age,
sex, medical history, lesion size, lesion type, reflux finding score (RFS), response
to treatment, duration of treatment, and follow-up period were compared.
Results Eighteen patients with CG and 14 patients with IG were included in the study. The
IG group had more female patients (p = 0.0009), showed better response to proton pump inhibitor (PPI) and steroid inhalation
(SI) (p = 0.036), and had a shorter treatment period (p = 0.0029) than the CG group. Five patients who received botulinum toxin injections
in their vocal cords had complete remission.
Conclusion Compared with CG, IG was more responsive to treatment with PPI and SI and required
a shorter duration of treatment.
