A Stepwise Integrative Approach to Managing a Refractory Recurrent Cervical Sialocele in a Dog

Year: 2026

Type: article

Abstract: Recurrent canine cervical sialocele is most often caused by incomplete excision of the mandibular-sublingual gland complex, leading to anatomical distortion and concealment of residual tissue. This case describes the multimodal management of a repeatedly recurrent cervical sialocele in a young, small-breed dog following multiple previous revision surgeries. A stepwise bridging strategy was adopted before definitive salvage surgery. Oral phenobarbital was instituted, resulting in partial reduction in fluid accumulation and improved comfort. Ultrasound-guided intracavitary sclerotherapy with OK-432 was then performed, inducing a localized fibrotic response but without durable cure. Final resolution was achieved only after salvage ventral paramedian (VPM) sialoadenectomy, which provided wide exposure for complete excision of deeply concealed sublingual remnant tissue within a fibrotic pseudocapsule. Histology confirmed a cervical sialocele. Transient neuropraxia resolved within 3 weeks, and no recurrence was observed at 6 months postoperatively. To the authors' knowledge, this is the first report describing intracavitary OK-432 sclerotherapy as part of a staged multimodal strategy for canine cervical sialocele. This case illustrates the feasibility of integrating medical salivary suppression and minimally invasive sclerotherapy as bridging measures before salvage VPM surgery for refractory cervical sialocele.
