title: [Closing an anterior sinusal opening using lyophilized dura].
abstract: The systematic application of lyophilized dura for closing the anterior opening of the maxillary sinus after primary and revisional surgery at the maxillary antrum is reported. This method was applied in 32 primary maxillary sinus operations and in 6 revisional operations. The follow-ups showed a satisfactorily small number of postoperative complaints. This allows the conclusion that lyophilized dura is a suitable material for closing the anterior window in operations on the maxillary sinus.
