Plain-English summary
In this study, three horses with a long-lasting problem called oromaxillary sinus fistula, which is an abnormal connection between the mouth and the maxillary sinus, underwent a specific surgical procedure. The surgery involved moving a muscle called the levator labii superioris, which helps lift the lip, to close the fistula. After the surgery, the horses healed well with few complications, and their appearance and function improved significantly. The findings suggest that this surgical technique is an effective way to treat this condition in horses.
Abstract
OBJECTIVE: To describe surgical transposition of the levator labii superioris muscle to treat oromaxillary sinus fistula in horses. STUDY DESIGN: Clinical study. ANIMALS: Three horses with chronic oromaxillary sinus fistula. METHODS: After severing its tendinous insertion, the muscle belly of the levator labii superioris muscle was retracted and transposed through the oromaxillary sinus fistula. The tendon exited the oral cavity through a full-thickness buccal incision created adjacent to the oral end of the fistula and was then tunneled subcutaneously in a ventral direction before being anchored by sutures to the cheek tissues. RESULTS: Fistulae healed with few complications and with good cosmetic and functional results. CONCLUSIONS: Oromaxillary sinus fistula associated with molariform tooth loss in horses can be treated successfully by transposition of the levator labii superioris muscle. CLINICAL RELEVANCE: Transposition of the levator labii superioris muscle should be considered for resolution of chronic oromaxillary sinus fistula in horses.
