BACKGROUND: The proportion of dental causes of @entity1180 is estimated between 10% and 40%. The mechanisms are manifold and originate from the close relation of the side teeth and the maxillary sinus. In the past, the transantral approach was commonly used by maxillofacial surgeons as their first choice. @entity1 AND METHODS: Between 01/1999 and 10/2001 38 @entity1 underwent endoscopic surgery controlled via the fossa canina. Apart from the mandatory treatment of the dental focus and the mucosal pathologies, a fenestration to the middle meatus of the nose was performed in 7 cases. RESULTS AND CONCLUSION: The dental medical history, @entity5299 , CT scans in coronary plane, endoscopic findings, and histology showed the commonly "silent" course of dental @entity1244 . Typical findings in CT scans are unilateral basal maxillary opacities adjacent to the @entity2651 . In 20% of the cases there was also a blockade of the infundibulum. All @entity1 were reexamined 6-12 months postoperatively. The @entity1 are free of symptoms, but sometimes suffer from @entity10 . An exact diagnosis and the clear separation of rhinogenic causes are vital points for the therapy of dental @entity1244 . In cases of unilateral @entity1244 , a comprehensive investigation by the maxillofacial surgeon should be recommended. Video-assisted endoscopic sinus revision is preferable to the transantral approach and is especially suitable for the treatment of mucosal @entity6112 , the removal of foreign bodies, endoscopically controlled resections of apical roots, elevations of the sinus floor, and dental implants. If the ethmoidal infundibulum and maxillary ostium are open, no fenestration is needed. In cases of blockade, fenestration to the middle nose canal is indicated.
