title: [Myospherulosis of the maxillary sinus].
abstract: BACKGROUND
  We present a case of a myospherulosis, describe the underlying cause and discuss ways of preventing its development.
  
  
  METHODS
  A 35-year-old man presented myospherulosis of the maxillary sinus caused by an antibiotic ointment placed in the sinus three years earlier during a Caldwell Luc procedure. The patient underwent a second Calwell Luc procedure. Outcome was uneventful and no recurrence was noted.
  
  
  CONCLUSIONS
  Histological examination should be ordered at reoperation and petroleum-based ointments and packings should be avoided in sinus surgery.
