One of the causes of recurrent maxillary sinusitis may be a too narrow natural ostium, which becomes blocked easily. As the mucus transport inside the sinus is directed towards the ostium, i.e, towards the middle nasal meatus, the most suitable place for an artificial extra ostium is in the middle meatus. In the posterior fontanelle such an ostium can be made comparatively easily under endoscopic control. For this purpose a special coagulating perforating instrument has been designed.
