The aim of this study was to investigate the existence of Helicobacter pylori (HP) in patients with benign and malignant vocal fold pathologies. This was a prospective clinical study conducted at a tertiary-care academic medical center. Fifty consecutive patients who had undergone microlaryngoscopy between August 2007 and July 2009 were included in the study. The patients with a reflux symptom index (RSI) above 12 and a reflux finding score (RFS) above 6 were accepted as having laryngopharyngeal reflux. Patients with urea breath test (UBT), HP-IgG, and HP cytotoxin-associated gene A (CagA)-IgG positivity were diagnosed as HP positive. During laryngoscopy, two surgical specimens were obtained, one from the primary vocal fold pathology and one from the interarytenoid region. The interarytenoid biopsy specimen was used for HP culture and PCR. The specimen from the vocal fold pathology was used to investigate the presence of HP. RSI was positive in 23 (46 %) patients. The RFS positivity was 56 %. The presence of HP was confirmed by UBT in 35 (70 %), HP-IgG in 37 (74 %), and HP CagA-IgG in 38 (76 %) patients. There was no difference between RFS-positive and RFS-negative patients in terms of HP-IgG and UBT. None of the interarytenoid or vocal fold specimens showed the presence of HP. HP was not found in the histological specimens of vocal fold pathologies and the interarytenoid region. The presence of HP in the gastric mucosa does not have an effect on the RFS and RSI.
