title: Broad indications for the application of simultaneous oral-nasal manometering method.
abstract: The purpose of the study is to enlarge and define the perimeter of application of manometrical method for investigation of nasal breathing.
  
  
  METHODS
  We studied patients with congenital or acquired pathological communications of the maxilla as well as patients with perforation of the sinus after teeth extractions that have been treated by prostheses. An original electronic pneumatic device was constructed for our method.
  
  
  RESULTS
  Because of the objectiveness of the method and the device we obtained good results in closing the pathological communications in all of the patients. When used in the diagnosis of sinus perforations the method and the device showed the same effectiveness,
  
  
  CONCLUSIONS
  When realization is possible the method guarantees absolute effectiveness in defining leakage of breathed air through pathological communications of the maxilla. With this device, constructed for the study we optimized the application of the method.
