Nasal foreign bodies identified by rhinoscopy in dogs: 42 cases

OBJECTIVE

To evaluate signalment, clinical presentation, location and type of nasal foreign bodies identified by rhinoscopy in dogs.

MATERIALS AND METHODS

We retrospectively reviewed medical records from dogs that presented for consultation between April 2012 and June 2019 and were diagnosed with nasal foreign body via rhinoscopy.

RESULTS

Forty-two dogs met the study's inclusion criteria. Thirty (71.4%; 30/42) were purebreds. Males accounted for 59.5% (25/42) of cases. The median age was 4.0 years old and 76.2% (32/42) were dogs up to 7 years of age. Mean bodyweight was 21.8 kg and dogs weighing more than 10 kg were overrepresented (78.6%; 33/42). Sneezing occurred in 78.6% (33/42) of cases. Foreign body retrieval was achieved by rhinoscopy in all cases. The foreign body was extracted from the right nasal cavity in 52.4% (22/42) of cases and from the left one in 42.9% (18/42). Two dogs (4.8%; 2/42) presented with one foreign body in each nasal cavity. Most nasal cavity foreign bodies (90.5%; 38/42) were grass awns. Three (7.2%; 3/42) were mineral and one (1/42) was fabric. Follow-up was documented for 35 patients, of which 97.1% (34/35) experienced resolution of clinical signs. Seven cases (16.7%; 7/42) were lost to follow-up.

CLINICAL SIGNIFICANCE

Nasal foreign bodies were more common in dogs up to 7 years of age and heavier than 10 kg. Sneezing was the primary clinical sign. The vast majority of foreign bodies were grass awns and rhinoscopy was an effective means of nasal cavity foreign body retrieval.

An Unusual Case of a Nasal Foreign Body in a Cat with Chronic Nasal Discharge

This report describes a cat infected with the feline infectious virus and a 1 yr history of unilateral mucopurulent nasal discharge. Intraoral radiography and endoscopic examination revealed the presence of a large fragment of tooth root in the right nasal cavity. The cat had previously undergone maxillary canine tooth (104) extraction. The root was successfully removed by an endoscopic-assisted procedure, and follow-up examination 1 yr later documented complete disappearance of the respiratory signs.

Imaging evaluation of dogs and cats with Dysphagia

The current literature is reviewed in this paper regarding the application of diagnostic imaging in the evaluation of swallowing disorders of the dog. The applications of radiography, contrast radiography, and contrast videofluoroscopy are discussed with pertinent case examples provided for emphasis. The indications for image-guided interventions are also described.
