Abstract
A six-year-old, male, castrated European shorthair cat was presented due to a lifelong history of sneezing, nasal discharge, open-mouth breathing, stertor and vestibular problems. Clinical examination showed absence of airflow through the nostrils. Computed tomography of the head revealed an infiltrative soft tissue attenuating mass in the left nasal cavity, nasopharynx and the left frontal sinus. All of these locations could be successfully accessed through ventral rhinotomy and the mass was completely removed. Histological examination identified it as an inflammatory polyp. All respiratory and neurological symptoms disappeared, and two-and-a-half years after surgery, the cat was still without complaints.
Highlights
In cats younger than two years of age, a mass in the nasopharynx is most commonly an inflammatory polyp (Allen et al, 1999)
Computed tomography of the head revealed an infiltrative soft tissue attenuating mass in the left nasal cavity, nasopharynx and the left frontal sinus. All of these locations could be successfully accessed through ventral rhinotomy and the mass was completely removed
These non-neoplastic growths arise from the lining of the auditory tube or the middle ear (Reed and Gunn-Moore, 2012)
Summary
In cats younger than two years of age, a mass in the nasopharynx is most commonly an inflammatory polyp (Allen et al, 1999) These non-neoplastic growths arise from the lining of the auditory tube or the middle ear (Reed and Gunn-Moore, 2012). It is necessary to incise the soft palate for additional surgical exposure (Kudnig, 2002) In this case report, a ventral rhinotomy approach is described for a large nasopharyngeal polyp that filled the left nasal conchae and even extended into the left frontal sinus
