Sites in the oropharynx reached by different methods of using mouthwash: clinical implication for oropharyngeal gonorrhoea prevention

What is it about?

SUMMARY • The prevalence and incidence of gonorrhoea infection is increasing among gay and bisexual men who have sex with men (MSM) and is commonly found in the tonsils and posterior pharyngeal wall. • Recent studies have looked at the impact of mouthwash against Neisseria gonorrhoeae bacteria in the oropharynx to address this rise, however it is unknown which parts of the oropharynx are reached by different mouthwash use methods (oral rinse, oral gargle and oral spray). • Oral spray is more effective at reaching the tonsils and posterior pharyngeal wall compared to rinse and gargle. • If mouthwash is effective in preventing oropharyngeal gonorrhoea, application methods that have greater coverage may be more efficacious.
