[Monoarthritis caused by Streptococcus pyogenes after nasal septoplasty: interest of the nasal decontamination in preoperative care].

The nasal septoplasty is a very current intervention in otorhinolaryngology surgery. The infectious complications of this intervention are rare and mostly mild. We report here the case of a patient hospitalized in ambulatory surgery within a fracture of the nose with luxation of the septum in the nasal fossa. This patient was operated for a reduction of this fracture with septoplasty. Twelve hours after the intervention the patient presented septic arthritis due to Streptococcus pyogenes. The tracks of prevention are presented.
