Zusammenfassung:Objective To compare complications of dogs treated with mandibular and sublingual sialoadenectomy for sialocele using a lateral (LAT) or ventral paramedian (VPM) approach. Study design Retrospective multicenter study. Animals Dogs (140) with mandibular and sublingual sialocele. Methods Medical records of dogs that underwent mandibular and sublingual sialoadenectomy through a LAT or VPM approach from 2004 to 2020 were reviewed. Clinical and histopathological findings were analyzed to compare the groups. Results Seventy dogs were included in each group. The most represented breed was crossbreed (26%), and males (99/140 [71%], intact/neutered) were overrepresented. Dogs in the VPM approach group were more likely to undergo digastricus tunnelization and placement of a drain or a bandage. Dogs in the LAT approach group were heavier and more likely to undergo excision of an inflammatory pseudocapsule. No difference was detected in complication rates between groups (LAT [20%], VPM [31%], P = .116). Recurrences were more likely after LAT approach (5/70 vs 0/70, respectively; P = .029), whereas wound‐related complications were more likely after VPM approach (20/70 vs 9/70, respectively; P = .018). Prolonged duration of surgery was associated with an increased risk of recurrence, and none of the other variables affected the complication rate. Conclusion Ventral paramedian approach for mandibular and sublingual sialoadenectomy was associated with a lower risk of recurrence but a higher risk of wound‐related complications compared with LAT approach. Clinical significance Ventral paramedian approach for mandibular and sublingual sialoadenectomy may be preferred to reduce recurrence in dogs with sialoceles, but wound‐related complications are common.
