Bilateral Abscessation and Extraction of the Mandibular Tusks in a 12 year old Vietnamese Potbellied Pig

Other Titles

Abstract

A 12 year old, male castrated Vietnamese Potbellied Pig was presented to Cornell University’s Equine & Nemo Farm Animal Hospital (ENFAH) in February 2018 following the diagnosis and unsuccessful conservative management of an apical abscess of his left mandibular tusk (304). Computed tomography (CT) scan and dental exam confirmed apical abscessation of both mandibular tusks (304, 404) as well as local, mandibular osteomyelitis. Due to the persistent abscessation and associated swelling, 304 was extracted entirely intraorally, using a coronal incision and an additional intra-oral incision to access the apex of the tusk buccal and ventral to 310 and 311along the horizontal ramus of the mandible. A 2-3 cm section of apical tusk was resected to allow removal of the remainder of the tooth through the coronal incision. During healing, the rostral flap closing the coronal incision dehisced and required further management to facilitate healing of the mandibular defect. An obturator was used to shield this opening during wound granulation; incrementally smaller obturators were used to replace the first as the defect healed. Several months later, the right mandibular tusk was extracted using an alternative approach. The incision to access the tusk apex was made extraorally, over the masseter and ramus of the mandible. Healing of the surgical site followed a similar course of healing – the mucosal tissue opened after dehiscence and exposed the large mandibular defect. Subsequent second intention healing was facilitated by the placement of an obturator.
