The spectrum of clinical presentation, methods of diagnosis, management and prognosis in cases of sinunasal cysts (SNCs) requires more extensive study. Despite the extensive nature of SNCs, the prognosis for afflicted horses appears to have improved since earlier studies were conducted.
To evaluate prognosis and cosmetic outcome of surgical ablation in 52 cases of SNCs.
Fifty-two case records (1982-2005) of horses affected with SNCs were retrieved from the archives. Subject details, clinical signs, diagnostic techniques, surgical management and post surgical complications were extracted. Owners and referring veterinarians were contacted to assess the results of treatment.
There was no biphasic age distribution. The major presenting signs in descending order of frequency were facial swelling, mucopurulent nasal discharge, nasal airflow obstruction and abnormal respiratory noise. Common endoscopic findings included narrowed nasal meati, a cyst in the nasal cavity and a cyst visible caudal to the nasal septum viewed from the contralateral unaffected nasal meatus. Typical radiological signs included a discrete mass in the sinunasal region, a diffuse increase in opacity over the sinunasal region, free fluid lines, nasal septal deviation, expansion of the ventral conchal sinus and distortion of dental apices. Cyst extirpation using an osteoplastic flap provided a successful outcome. Forty-five of 48 horses showed complete resolution of clinical signs after subtotal or total extirpation of the cyst wall. Follow-up information was not available for the other 3 horses. Thirty-nine of 45 horses had a good to fair cosmetic appearance, judged to be good in 26 horses, fair in 13 and poor in 6. Results confirmed that the prognosis for full recovery has improved since a previous report of 15 cases.
Equine sinunasal cysts may arise in horses of any age; presenting signs should alert clinicians to their likely presence. A discrete well-circumscribed mass found during radiographic examination provides supporting evidence of a cyst. The vivid yellow, translucent, seromucoid fluid aspirated from cysts is characteristic of the condition.
鼻窦囊肿（SNCs）病例的临床表现范围、诊断方法、治疗手段及预后情况需要更广泛的研究。尽管鼻窦囊肿较为常见，但自早期研究开展以来，患病马匹的预后似乎有所改善。
评估52例鼻窦囊肿病例手术切除后的预后及美容效果。
从档案中检索出52例（1982 - 2005年）患有鼻窦囊肿的马匹病例记录。提取病例详细信息、临床症状、诊断技术、手术治疗及术后并发症。联系马匹主人及转诊兽医以评估治疗结果。
发病年龄无双峰分布。按出现频率从高到低排列，主要临床表现为面部肿胀、黏液脓性鼻分泌物、鼻气流阻塞及异常呼吸音。常见的内镜检查结果包括鼻道变窄、鼻腔内囊肿以及从对侧未受影响的鼻道观察到鼻中隔后方可见囊肿。典型的放射学征象包括鼻窦区域的孤立肿块、鼻窦区域透明度弥漫性增加、游离液平面、鼻中隔偏曲、腹侧鼻甲窦扩张及牙尖变形。采用骨成形瓣进行囊肿摘除取得了成功。48匹马中有45匹在囊肿壁部分或全部摘除后临床症状完全消失。另外3匹马没有随访信息。45匹马中有39匹美容效果良好至中等，其中26匹马美容效果良好，13匹马中等，6匹马较差。结果证实，自之前15例病例报告以来，完全康复的预后有所改善。
马鼻窦囊肿可发生于任何年龄的马匹；出现的症状应提醒临床医生注意其可能存在。放射学检查中发现的边界清晰的孤立肿块为囊肿提供了支持性证据。从囊肿中抽出的鲜黄色、半透明、浆液黏液样液体是该病的特征。
