The objective of this study was to evaluate the effectiveness of balloon dilation for the treatment of nasopharyngeal stenosis in cats.
The medical records of seven cats with nasopharyngeal stenosis treated with balloon dilation were reviewed. The most common presenting clinical signs included upper airway noise, sneezing, nasal and/or ocular discharge. All seven cats were confirmed to have nasopharyngeal stenosis via nasopharyngeal endoscopy and were treated with balloon dilation under endoscopic guidance.
All seven cats had acceptable short-term control (median 14 days) of clinical signs after the procedure. Two of six cats had successful long-term control (median 34 days) of clinical signs after one balloon dilation and an additional 2/6 cats had acceptable long-term control of clinical signs after a second balloon dilation procedure. The most significant complication of balloon dilation was the recurrence of stenosis.
The findings of this study indicate that balloon dilation is a safe and effective treatment option for the relief of clinical signs associated with nasopharyngeal stenosis in cats. Multiple procedures may be necessary for the best chance of long-term success.
本研究的目的是评估球囊扩张术治疗猫鼻咽狭窄的有效性。
回顾了7只接受球囊扩张术治疗的鼻咽狭窄猫的病历。最常见的临床表现包括上呼吸道杂音、打喷嚏、鼻和/或眼部分泌物。所有7只猫均通过鼻咽内窥镜检查确诊为鼻咽狭窄，并在内窥镜引导下接受球囊扩张术治疗。
所有7只猫术后临床症状均得到了可接受的短期控制（中位时间14天）。6只猫中有2只在一次球囊扩张术后临床症状获得了成功的长期控制（中位时间34天），另外2/6的猫在第二次球囊扩张术后临床症状得到了可接受的长期控制。球囊扩张术最显著的并发症是狭窄复发。
本研究结果表明，球囊扩张术是缓解猫鼻咽狭窄相关临床症状的一种安全有效的治疗选择。为获得最佳的长期成功机会，可能需要进行多次手术。
