Abstract

Objective: To describe a novel surgical approach to conjunctivorhinostomy for feline nasolacrimal duct obstruction.

Animal studied: A client-owned 4-year-old female spayed domestic shorthair cat presented with chronic unilateral nasolacrimal duct obstruction of the right eye.

Methods: Following obstruction confirmation via complete ophthalmic examination and dacryocystorhinography, conjunctivorhinostomy was performed under general anesthesia, and an indwelling sub-palpebral lavage (SPL) line was placed to facilitate the formation of a new pathway for tear drainage. Specifically, the SPL footplate was sutured to the ventral conjunctival fornix with 5-0 nylon and 6-0 vicryl while the tubing was passed through the new pathway and the distal end of the tubing trimmed and tucked into a perinasal subcutaneous pocket. Two skin sutures closed the perinasal pocket and were removed 2 weeks postoperatively.

Results: No immediate postoperative complications occurred. At 6 weeks and 6 months postoperatively, the distal SPL tubing was dislodged and visible out of the right nostril. This was uneventfully trimmed shorter, and no further complications occurred. The SPL component was easily removed 11 months postoperatively without complication. The patient's clinical signs dramatically improved; she was comfortable over 2 years after surgery.

Conclusion: To the authors' knowledge, this is the first report of using an SPL as an indwelling catheter for nasolacrimal duct surgery via conjunctivorhinostomy in a cat. This technique eliminated external stent sites for the patient, which was associated with a short use of an e-collar, and utilized materials readily available in a specialty hospital.

使用睑板下灌洗液管作为留置支架来处理猫单侧鼻泪管阻塞的新方法。
目的描述一种治疗猫科动物鼻泪管阻塞的新型结膜鼻腔造口手术方法:研究动物:一只客户饲养的 4 岁雌性去势短毛猫,右眼患有慢性单侧鼻泪管阻塞:方法:通过全面眼科检查和泪囊造影确认阻塞后,在全身麻醉下进行了结膜鼻腔造口术,并放置了留置的睑板下灌洗管(SPL),以促进形成新的泪液引流途径。具体来说,用 5-0 尼龙和 6-0 维克瑞尔将 SPL 脚板缝合到腹侧结膜穹窿上,同时将管道穿过新通道,修剪管道远端并将其塞入肛周皮下袋中。两处皮肤缝合关闭肛周皮下袋,术后两周拆除:结果:术后未立即出现并发症。术后 6 周和 6 个月时,SPL 管远端移位,从右鼻孔可见。在顺利修剪后,未再出现并发症。术后 11 个月,SPL 组件被轻松移除,未出现并发症。患者的临床症状明显改善,术后两年多一直感觉舒适:据作者所知,这是首次报道使用 SPL 作为留置导管,通过结膜鼻腔造口术对猫进行鼻泪管手术。这项技术消除了患者的外部支架部位,这与短期使用电子项圈有关,而且利用了专科医院现成的材料。
