Adenocarcinoma is the most common tumor in the canine nasal cavity. Fibroma, chondroma, osteoma, and squamous cell carcinoma are also seen. Benign nasal polyps are rare in dogs.
Causes of Nasal Cavity Tumor
The cause is unknown.
Main Symptoms of Nasal Cavity Tumor
The disease mainly occurs in elderly long-headed dogs. Usually only a small amount of gas can pass through the nostril of the affected nasal cavity, and symptoms of dyspnea or heavy mouth breathing due to upper airway obstruction can be clearly observed. Watery, viscous, viscous, or bloody nasal fluid may be present in one or occasionally both nostrils. If the tumor grows through the nasal cavity or the anterior frontal bone, the animal may present with pain or facial distortion. If the tumor enters the skull, the animal will show symptoms of neuropathy.
Diagnostic Criteria for Nasal Cavity Tumors in dogs
The X-ray features were mainly accompanied by the loss of turbinate bone, the increase of the opacity of uniform soft tissue, the damage of pear bone, the deviation of nasal septum to one side, and sometimes the increase of soft tissue area beyond the nasal cavity, leading to the animal's facial bone injury. When a tumor has grown into a normal canal or into the nasopharynx, the diagnosis is often confirmed by means of rhinoscopy. The type of tumor can be determined by drawing a biopsy as a diagnostic sample for biopsy.CT or MRI can well show the extent of tumor spread and can provide reference for treatment plan.
Treatment Methods of Nasal Cavity Tumor
Surgical operation can reduce the tumor cells and relieve the pain of respiratory obstruction, but the disease often recurs.Treatment with megavolage radiation alone, or in combination with surgery, can effectively improve the course of treatment.
