Abstract

Laryngeal papillomatosis is the most common of benign laryngeal neoplasms, different factor may play role in incidence of laryngeal papiloma but Human papillomavirus and may be Helicocabacter Pylori one of the most important of them. Aim in this study is the presence of Helicobacter pylori and Human papillomavirus in laryngeal papilloma. Polymerase chain reaction was employed for detection of Helicobacter pylori and Human papillomavirus DNA from 41 biopsy samples of laryngeal papilloma. Three samples of 41 biopsy samples for the presence of HP DNA and 19 samples from 41 biopsy of patient for HPV DNA were positive. At this study we evaluate the role of Helicobacter pylori and human papillomavirus on laryngeal papilloma. The author found that although, Helicobacter pylori is no dominant agent in incidence of laryngeal papilloma but Human papillomavirus can be a dominant risk factor for development of it.
