Diagnosis and Surgical correction of salivary affections in buffaloes (Bubalus bubalis); a retrospective study.

AIM: This study aimed to describe the diagnosis and treatment of various surgical salivary affections in buffaloes. MATERIALS AND METHODS: This study included 135 buffaloes examined at Dakahlia Governorate between 2011 and 2022 suffering from various surgical salivary affections. The recorded surgical affections had salivary fistula (n = 44), ectasia of Stenson's duct (n = 11), ranula/mucocele (n = 46), and cervical sialocele (n = 34). The buffaloes were sedated using an intramuscular injection of xylazine (0.05 mg/kg) and local infiltration analgesia of lidocaine for specific surgical interventions. RESULTS: The salivary duct fistula cases were surgically corrected using a retrograde infusion of povidone-iodine into the duct and its double ligation with Prolene following fistulectomy. Intraoral marsupialization was done in buffaloes suffering from ectasia of the parotid duct. The mucocele /ranula was surgically incised with daily flushing with povidone-iodine. The cervical sialocele was treated by giving an elliptical excision on the sialocele, and sialoadenectomy of the mandibular salivary gland was performed to facilitate dynamic fluid/saliva drainage. A 92.5% of diseased buffaloes showed an uneventful recovery without any postoperative complications after the first treatment, whereas 7.5% of animals tended to recur. The most common and almost equally distributed salivary affections recorded in adult buffaloes were parotid duct fistula, mucocele, and cervical sialocele. The Stenson's duct ectasia was commonly registered in calves, being congenital. CONCLUSION: Ranula was the most common salivary affection encountered in adult buffaloes, closely followed by parotid duct fistulae and cervical sialoceles. Stenson's duct ectasia was the least encountered salivary affection in calves and was congenital. All salivary affections were corrected easily and safely, with satisfactory outcomes.

Transoral approach for mandibular and sublingual sialoadenectomy in a cat.

Sialocele is an uncommon condition in cats. The treatment of choice for sublingual sialocele is excision of the ipsilateral mandibular and sublingual salivary gland/duct complex. Lateral and ventral cervical approaches have been described for mandibular-sublingual sialoadenectomy; however, the transoral approach, described here, has never been reported in cats. Ranula in the present case was likely caused by an inadvertent trauma of the sublingual duct during resection of a sublingual lesion performed by the referring veterinarian. The definitive surgery consisted of mass removal and sialoadenectomy through a unique oral approach. The surgery was effective without complications encountered after 6 months of follow-up. Key clinical message: This article reports a novel, transoral approach, for mandibular and sublingual sialoadenectomy in the cat. This approach decreases the surgical time and prevents recurrence of the mucocele.

Approche trans-orale pour la sialo-adénectomie mandibulaire et sublinguale chez un chat. La sialocèle est une maladie rare chez les chats. Le traitement de choix pour la sialocèle sublinguale est l'excision du complexe glandes salivaires/canal salivaire ipsilatéral mandibulaire et sublingual. Des approches cervicales latérales et ventrales ont été décrites pour la sialo-adénectomie mandibulaire-sublinguale; cependant, l'approche trans-orale, décrite ici, n'a jamais été rapportée chez les chats. Dans le cas présent, la ranula a probablement été causée par un traumatisme involontaire du canal sublingual lors de la résection d'une lésion sublinguale réalisée par le vétérinaire référent. La chirurgie définitive consistait en un enlèvement de masse et une sialo-adénectomie par une approche orale unique. La chirurgie a été efficace sans complications rencontrées après 6 mois de suivi.Message clinique clé :Cet article rapporte une nouvelle approche trans-orale pour la sialo-adénectomie mandibulaire et sublinguale chez le chat. Cette approche diminue le temps chirurgical et empêche la récidive de la mucocèle.(Traduit par Dr Serge Messier).
