Feline inflammatory aural polyps (IP) have been reported as solitary growths, yet bilateral polyps may occur more commonly than described previously.
To identify the prevalence and risk factors associated with bilateral feline IP within a population of cats evaluated at a veterinary teaching hospital over a 10 year period.
Twenty-five cats with histologically confirmed IP.
A retrospective study was performed by searching computerized medical records of cats seen at The University of Tennessee Veterinary Teaching Hospital from 2005 to 2015. Keywords used for the search included "feline polyp", "ventral bulla osteotomy", "inflammatory polyp ear canal" and "nasopharyngeal polyp".
Cats were separated into groups with unilateral or bilateral disease. Six of 25 (24%) cats had bilateral IP. Twelve cats had computed tomography performed (four of six with bilateral IP; eight of 19 with unilateral IP). Clinical signs, history of upper respiratory infection, post-treatment complications, and IP recurrence with and without local and systemic steroid administration were studied between groups and no differences were identified. In four of six cats with bilateral disease, the second polyp was identified with advanced imaging performed at the time of referral.
These findings demonstrate that bilateral IP occur more frequently than reported previously and establish a prevalence for bilateral IP. These findings also highlight the value of advanced imaging techniques in diagnosing bilateral IP.
猫的炎性耳息肉（IP）已被报道为孤立性生长，但双侧息肉的发生可能比以前描述的更为常见。
在一家兽医教学医院对猫进行为期 10 年的评估中，确定猫双侧 IP 的流行率和相关风险因素。
25 只经组织学证实患有 IP 的猫。
通过检索 2005 年至 2015 年期间在田纳西大学兽医教学医院就诊的猫的计算机化病历，进行了一项回顾性研究。用于搜索的关键词包括“猫息肉”、“鼓室腹侧切开术”、“炎性息肉耳道”和“鼻咽息肉”。
将猫分为单侧或双侧疾病组。25 只猫中有 6 只（24%）患有双侧 IP。12 只猫进行了计算机断层扫描（6 只双侧 IP 中有 4 只；19 只单侧 IP 中有 8 只）。研究了组间的临床症状、上呼吸道感染史、治疗后并发症、以及有无局部和全身类固醇治疗的 IP 复发情况，但未发现差异。在 6 只双侧疾病的猫中，有 4 只在转诊时通过先进的影像学检查发现了第二只息肉。
这些发现表明双侧 IP 的发生频率高于以前的报告，并确定了双侧 IP 的流行率。这些发现还强调了先进影像学技术在诊断双侧 IP 中的价值。
