Sie kommen geh\u00e4uft beim\n                    brachyzephalen Hund vor. Durch ihr expansives Wachstum k\u00f6nnen Zysten im\n                    Oberkiefer in die Nasenh\u00f6hle einbrechen, den nasalen Atemweg verlegen\n                    und Ursache f\u00fcr Nasenausfluss sein. Eine neue endonasal-endoskopische\n                    Intervention zur Entfernung dieser Zysten soll beschrieben werden.<\/jats:p><jats:p>\n          Material und Methoden Es wurden 4 brachyzephale Hunde (Boxer, Mops,\n                    Chihuahua, Franz\u00f6sische Bulldogge) mit unilateralen, die\n                    Nasenh\u00f6hle obstruierenden Zysten in die Studie eingeschlossen. Die Tiere\n                    wurden klinisch, computertomografisch, rhinoskopisch und Bioptate der Zystenwand\n                    histologisch untersucht. Neben einer Zahnsanierung und einer konventionellen\n                    Extraktion des involvierten Zahnes wurde die Zystenwand\n                    endoskopisch-interventionell durch das physiologische Nasenloch entfernt.

Der\n                    nasale Luftstrom war bei allen Patienten eingeschr\u00e4nkt. Die Entfernung\n                    der Zysten und involvierten Z\u00e4hne verlief ohne intra- und postoperative\n                    Komplikationen. Rezidive der Zysten wurden nicht beobachtet.
