Marsupialização de rânula bilateral em cão – relato de caso

Abstract

The supervised internship was split between COMIGO (Palmeiras de Goiás), 222h focused on livestock production medicine, and Egídio Pet Shop & Clínica VET 24h, 222h in small animal practice. At COMIGO I joined farm visits to dairy, beef and swine operations, performing reproductive ultrasounds, TAI, silage and BCS evaluations, clinical cases, hoof trimming, brucellosis vaccination, and nutritional/sanitary management. At the small animal clinic I followed 185 consultations, 54 lab collections, 74 surgeries including OHE, orchiectomy, C-section and pyometra, plus vaccinations and imaging.The case report describes bilateral ranula in a 14-year-old female Pinscher, 3.8kg, seen at Egídio Pet Shop & Clínica VET 24h. She had bilateral sublingual swelling, ptyalism, dysphagia and halitosis. Labs showed mild lymphopenia, neutrophilia and high ALT; creatinine normal. CT showed C5-C6 disc extrusion with ∼40% cord compression, but surgical focus was the ranula. Dental scaling was done first, then bilateral marsupialization: elliptical incision of sublingual mucosa, excision of pseudocyst walls, and suture of mucosal edges with absorbable suture to create permanent drainage. Anesthesia: acepromazine + methadone premed, ketamine + propofol induction, isoflurane maintenance. Post-op: dipyrone, amoxicillin, meloxicam, soft diet. Healing was uneventful with no recurrence. Marsupialization proved safe, fast and effective for sublingual salivary mucoceles, with excellent prognosis when properly performed.
