[A comparative study of therapy effects between esomeprazole plus mosapride citrate and botulinum toxin injection on vocal process granuloma]

Abstract

Objective:Anti-reflux medications or botulinum toxin A injections are the main current therapies for the definite vocal process granuloma. This studies is focusing on comparing the effects of proton pump inhibitors plus prokinetic agents with botulinum toxin A injections on vocal process granuloma. Method:Adult patients in our outpatient department (from December 2014 to June 2016) complaining of trachyphonia and/or abnormal pharyngeal sensations who were found to have contact granulomas (38 cases) were included. Patients were divided into two groups according to the treatment selected by themselves: esomeprazole with mosapride citrate (n=28) or botulinum toxin A injection (n=20). The reflux symptom index and reflux finding score determined by electronic fibrolaryngoscopy were utilized to assess efficacy. Result:There was no statistical difference on age, sex and reflux symptom index and reflux finding score before treatment between the two groups. Total effective rate in the esomeprazole with mosapride citrate group and the botulinum toxin A group were 96.43% and 45.00%, separately. The recorded symptoms after therapy resolved with a statistically significant improvement in the esomeprazole with mosapride citrate group. Conclusion:Combined proton pump inhibitor plus prokinetic drug therapy plays a significant role in the treatment of vocal process granulomas.
