Objectives:

Retroflexed endoscopic access to the nasopharynx for diagnostic and therapeutic goals can be challenging, and requires the use of relatively small flexible endoscopes, which can impair visualization and the operator’s ability to feed biopsy forceps or other instruments through the working channel, limiting interventions in this region.

The aim of this study is to report our experience with a retro-esophagoscopic approach (ROSA) in three dogs suffering from nasopharyngeal disease.

Methods:

The medical records of dogs that underwent ROSA for nasopharyngeal diseases were reviewed. Three cases met the inclusion criteria. Signalment, clinical signs, diagnostic imaging modality, the type of procedure and hospitalization times, as well as complications, and outcomes were recorded.

Results:

Three dogs met the inclusion criteria. Clinical signs were reverse sneezing, nasal discharge, stertor and retching. Computed tomography examination was available for all three dogs. In all cases, normograde and retroflexed endoscopy was attempted but was unsuccessful. In two cases a flexible and in 1 case a rigid enoscope was inserted through a small esophagostomy approach, and advanced rostrally into the nasopharynx. Successful foreign body retrieval was performed in cases 1 and 2 and balloon dilatation was performed in case 3 followed by nasopharyngeal stent placement under retroflexed endoscopic and fluoroscopic guidance. No intra-operative or postoperative complications occurred.

Conclusions:

The ROSA allows successful assessment and the use of instruments for interventional procedures in the nasopharynx. To the author’s knowledge, this is the first report of ROSA to treat nasopharyngeal diseases in dogs.
