Two dogs with previous parotid duct transpositions presented with unrelated ocular disease. In both cases, ophthalmic examination revealed the need for enucleation or exenteration. In case 1, systemic coccidioidomycosis was diagnosed with panuveitis and secondary glaucoma of the left eye. In this case, the parotid duct was ligated at the time of enucleation to stop salivary secretions. This dog encountered morbidity in the form of a sialocele that did not resolve for 11 months. In case 2, ultrasound and computed tomography revealed a discrete mass within the left medial orbit that was suspected to arise from the nictitating membrane. A combination of exenteration and parotid duct transposition reversal was performed to avoid morbidity associated with ligation of the parotid duct. The dog encountered no complications from this novel procedure. This case report represents the first report of re-routing a transposed parotid duct from the ventral conjunctival sac back to the mouth at the time of enucleation or exenteration in the dog.
两只曾接受腮腺导管移位术的犬出现了不相关的眼部疾病。在这两个病例中，眼科检查均显示需要进行眼球摘除术或眼眶内容剜除术。病例1中，全身性球孢子菌病被诊断为伴有左眼全葡萄膜炎和继发性青光眼。在此病例中，眼球摘除时结扎腮腺导管以阻止唾液分泌。这只犬出现了涎囊肿形式的发病情况，持续11个月未消退。病例2中，超声和计算机断层扫描显示左内侧眼眶内有一个离散性肿块，怀疑起源于瞬膜。为避免与腮腺导管结扎相关的发病情况，实施了眼眶内容剜除术和腮腺导管移位术反转联合手术。这只犬未因这一创新手术出现并发症。本病例报告是关于犬在眼球摘除术或眼眶内容剜除术时将移位的腮腺导管从腹侧结膜囊重新引回口腔的首次报告。
