“…Two techniques to repair an oroantral fistula have been previously described (Orsini and Ross ; Hahn and Kohler ; Brink ). Using these techniques, one end of the levator nasolabialis muscle or the levator labii superioris muscle is transposed through the sinus and into the fistula (Orsini and Ross ; Hahn and Kohler ; Brink ). Both muscles lie on the maxilla and insert rostrally at the nose or the commissure of the lips.…”

Summary An 8‐year‐old Andalusian stallion was presented to the Equine Hospital with a 1.5 year history of an oronasal fistula measuring approximately 2 cm long (caudal to rostral) by 1.5 cm wide following an oral extraction of the right second maxillary premolar (106). An alveolar bone flap was created adjacent to the oronasal fistula and rotated axially and ventrally to close the oral aspect of the fistula. At 3 days after surgery, clinical signs of the fistula, such as green‐tinged purulent nasal discharge and malodorous breath, were no longer evident. At 10 days after surgery, the oral opening of the fistula filled with granulation tissue and mucosa and decreased in size to less than 2 ml. The horse was fed a pelleted mash and grass diet and the small fistula was flushed orally twice daily until it completely healed. At 6 months following surgery, the fistula had completely healed. Few options are available for repairing an oroantral or an oronasal fistula in horses. This case report suggests that a large, chronic oronasal fistula involving the alveolus of a maxillary second premolar can be repaired successfully with an alveolar bone flap.

“…). Most oroantral or oronasal fistulae result from incorrect placement or premature loss of a temporary alveolar plug, incomplete removal of dental tissue, development of osseous sequestra or chronic alveolar infection (Barakzai and Dixon ; Brink ; Hawkes et al . ).…”

“…If the fistula fails to resolve by temporarily sealing its oral aspect, more elaborate means of occluding the fistula must be used, such as covering the oral aspect of the fistula with a sliding mucoperiosteal flap (Barakzai and Dixon 2005) or filling the fistula with transposed muscle (Brink 2006). Barakzai and Dixon (2005) described the use of a mucoperiosteal flap to treat a horse with an oronasal fistula, which was associated with the loss of the second and third premolars in a maxillary arcade.…”

“…Horses with an oromaxillary sinus fistula have been treated successfully by occluding the lumen of the fistula with a transposed portion of the levator nasolabialis muscle (Orsini et al . 1992) or the levator labii superioris muscle (Brink 2006). The levator labii superioris muscle is easily transposed and, because it is ellipsoid in cross‐section, it is better suited than the flat, levator nasolabialis muscle to occlude an orosinus or oronasal fistula (Brink 2006).…”

Summary A sinocutaneous or nasocutaneous fistula is usually a sequel to a comminuted fracture of one or more facial bones, whereas an oronasal or oromaxillary sinus fistula occurs most commonly after a maxillary alveolus fails to fill with healthy granulation tissue after its tooth has been lost. Horses with a sinocutaneous or nasocutaneous fistula can be treated by covering the fistula with transposed muscle, which in turn is covered by adjacent skin or a free skin graft, or by covering the fistula with periosteum transposed from adjacent bone, itself covered by adjacent skin or left uncovered to heal by second intention. Horses with an oronasal or oromaxillary sinus fistula can usually be treated successfully by temporarily occluding the oral aspect of the fistula, to prevent feed from entering the fistula, until the apical end of the alveolus fills with healthy tissue. Other methods of treatment include covering the oral aspect of the fistula with a mucoperiosteal flap or filling the fistula with a transposed facial muscle.
