Surgical correction of a bilateral congenital nasal pyriform aperture stenosis in a French Bulldog

A four-month-old, male, intact French Bulldog was presented with bilateral purulent nasal discharge and difficulties in breathing. A congenital nasal pyriform aperture stenosis with closure of both nasal cavities was diagnosed. The aperture was surgically opened through a midline approach, and a covered metallic stent (CMS) was inserted in each nasal cavity to prevent the newly constructed airway from obstructing. Seven weeks after implantation, the left nasal cavity was obstructed by granulation tissue. Further diagnostics revealed that the left stent had migrated caudally. The aperture had to be reopened and a new stent was placed. The right stent was removed endoscopically at that time, the left stent was removed six weeks after implantation. Four weeks after the removal of the left stent, the dog had normal airflow through both nares with very mild serous nasal discharge.
