Dorsomedian nasopharyngeal masses with benign appearance in dogs: A retrospective medical review of 95 cases among 198 dogs (2019-2022).

Background: Dorsomedian nasopharyngeal masses with benign macroscopic appearance are frequently observed during retrograde nasopharyngoscopy, particularly in brachycephalic breeds, but are not well described.

Hypothesis/objectives: To characterize these masses, assess their frequency, and identify the potential factors associated with their presence.

Animals: Dogs that underwent retrograde nasopharyngoscopy at a private hospital.
