Complications of Mandibular Brachygnathism in a North African Leopard

Abstract

A 9-year-old, male North African leopard (Panhtera pardus) presented with mandibular brachygnathism and lingually displaced mandibular canine teeth causing a large left oronasal fistula, rhinitis and nasal discharge, and a right orocutaneous fistula. Surgical closure of the left oronasal defect, bilateral mandibular canine tooth crown reduction, and root canal therapy resulted in a positive clinical outcome. A small recurrent left oronasal fistula and the right orocutaneous fistula healed spontaneously after alleviating the occlusal contact with the mandibular canine teeth. At 12-months postoperatively, clinical signs of oral and dental disease had resolved.

Oral, Maxillofacial and Dental Diseases in Captive Cheetahs ( Acinonyx jubatus )

“…The cheetah (Acinonyx jubatus) is classified as a large felid that shares some characteristics with the Canidae (Caro, 1994). A variety of oral, maxillofacial and dental conditions/diseases (OMFD's) occurs in captive felids, mainly lions, tigers, leopards and snow leopards (Heuschele, 1959;Willis, 1983;Cook and Stoller, 1986;Beebe and Hulland, 1988;van Foreest and Roeters, 1997;van Foreest et al, 1999;Sundberg et al, 2000;De Simoi, 2006;Barycka, 2007;Sykes et al, 2007;Longley, 2011). Although these studies help to describe the pathology seen in these captive big cats, few such reports are currently available for free living big cats (Van Valkenburgh, 1988;Miles and Grigson, 1990;Van Valkenburgh and Hertel, 1993;Longley et al, 2007).…”

Reverse Pedicle U-Shaped Palatal Flap: An Innovative Technique for Repair of Severe Caudal Palatal Defects in Two Dogs

“…36,55 The mainstream concept of the surgical technique described is the fact that the blood supply of the palate derives partially from nasal vessels such as sphenopalatine and lateral nasal branches, mostly if the major palatine arteries are compromised due to trauma or other causes. 15 However, these vessels reach the palate rostrally, not supporting the creation of the described technique. Then, to understand the vascular supply of the part of the palate rostral to the defect an angiographic CT was performed in Case #1 which showed that an extremely large number of vessels reached both the rostral and the distal part of the palate rostral to the defect without pinpointing the origin of this dense vascular network.…”

“…Etiologies of acquired palatal defects are many, including trauma, dental pathology, electric burns, radiotherapy, malocclusion, dehiscence, tumors, and foreign bodies. 9–18…”

“…Etiologies of acquired palatal defects are many, including trauma, dental pathology, electric burns, radiotherapy, malocclusion, dehiscence, tumors, and foreign bodies. [9][10][11][12][13][14][15][16][17][18] Communication between the oral cavity and nasal cavity, orbits, or maxillary recesses leads to secondary infections such as rhinitis, aspiration pneumonia, and ocular infections. [19][20][21][22][23] Treatment planning and the decision-making process are highly linked to advanced diagnostic imaging techniques such as fan beam computed tomography (FBCT) or cone beam computed tomography (CBCT).…”
