Treatment of a periorbital cyst in a dog by creation of a permanent drainage opening

Summary

An inflammatory periorbital cyst with secondary pressure atrophy of the maxilla was treated by surgical creation of a drainage opening to the nasal cavity in a 4-year-old Yorkshire Terrier. Following treatment, clinical signs resolved and computed tomography 5 weeks after surgery confirmed the permanence of the drainage opening. Eight months later, the dog showed no clinical abnormalities. Therefore, the procedure described in this report may offer a suitable treatment option in cases where the cyst’s size or localization prevents complete excision.

Zusammenfassung

Bei einem 4-jährigen Yorkshire Terrier wurde eine periorbitale entzündliche Zyste, die zu einer sekundären Druckatrophie der Maxilla führte, durch Anlegen einer Drainageöffnung zur Nasenhöhle hin behandelt. Die klinischen Symptome verschwanden daraufhin und eine Computertomographie 5 Wochen postoperativ bestätigte die Dauerhaftigkeit der Drainageöffnung. Auch 8 Monate später zeigte der Hund keine klinischen Auffälligkeiten. Der beschriebene Eingriff stellt somit eine Behandlungsoption für periorbitale Zysten dar, bei denen eine vollständige Exzision aufgrund von Größe oder Lokalisation nicht möglich ist.
