“…The periosteum used to cover the defect is covered with surrounding skin (Schumacher et al . 1985; Charman and Vasey 2007) or left uncovered to heal by second intention as reported by Velde et al. (2010) in this issue.…”

“…If the fistula is located at a site that is either too remote from a muscle that can be transposed to cover it or is too large to be covered by a transposed muscle, then the fistula can be healed by covering it with adjacent periosteum (Schumacher et al . 1985; Charman and Vasey 2007; Velde et al . 2010).…”

“…Bone denuded of periosteum to create the periosteal flap(s) forms new periosteum, and the osteogenic, cambium layer of the periosteal flaps forms new bone (Schumacher et al . 1985; Charman and Vasey 2007). Cancellous bone, harvested from the sternum or the wing of the ilium, can be interposed between the periosteal flap(s) and the cutaneous transposition flap to induce formation of bone, but application of cancellous bone is not necessary for osseous healing of the fistula.…”

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.

“…The key factor for successful closure of a nasocutaneous or sinocutaneous fistula appears to be the creation of a tissue barrier between the contaminated cavity and the overlying skin (Barber and Stashak 2008). Tissue barriers that have been used for this purpose include mucosa (Waldridge et al 1997), muscle (Campbell and Peyton 1984), skin (Madison et al 1989) and periosteum (Schumacher et al 1985;Charman and Vasey 2007;Barber and Stashak 2008).…”

Summary Head injuries occur frequently in horses and a successful outcome after repair depends upon the severity of the initial trauma, the anatomical structures involved and the extent of tissue loss. Often these injuries involve facial bones and enter into the nasal passages or paranasal sinus system. When these injuries occur in conjunction with substantial tissue loss, the resulting defect may be difficult to close and naso/sinocutaneous fistulae can develop. These defects can be challenging and time consuming to repair and an appropriate reconstructive technique must be selected. We describe the use of reverse periosteal flaps as a technique in repairing large nasocutaneous fistulae in 2 horses after previous attempts to close the defects by other means had failed.

“…Delayed closure of sinocutaneous fistulae with muscle and/or periosteal flaps has been described by Campbell and Peyton (1984), Schumacher and others (1985), Dart and others (1994) and Charman and Vasey (2007). This short communication describes the successful primary closure of a large facial wound in a horse, complicated by a comminuted fracture of the frontal bone into the conchofrontal sinus, using pedicles of the temporal muscles and underlying periosteum.…”

WoUNDs to the dorsal aspect of the skull of horses that involve fracture of the frontal bones into the conchofrontal sinus are not uncommon. Healing of these wounds can be complicated by bacterial sinusitis, formation of a sinocutaneous fistula and/or facial deformity. The closure of wounds penetrating the conchofrontal sinus is often delayed, either due to neglect or because of concerns about infection that could accompany primary closure. Delayed closure of sino cutaneous fistulae with muscle and/or periosteal flaps has been described by campbell and Peyton (1984), schumacher and others (1985), Dart and others (1994) and charman and Vasey (2007). This short communication describes the successful primary closure of a large facial wound in a horse, complicated by a comminuted fracture of the frontal bone into the conchofrontal sinus, using pedicles of the temporal muscles and underlying periosteum. a three-year-old thoroughbred gelding was referred to the University of Tennessee large animal Hospital within 24 hours of sustaining a facial wound complicated by fracture of the frontal bone with exposure of the conchofrontal sinus. The cause of the injury was unknown. The horse had been seen by a referring veterinarian, who cleaned the wound, administered 2 g phenylbutazone intravenously and referred the horse for definitive treatment. on presentation, physical examination revealed no abnormalities except for a large, T-shaped, jagged wound, 8 cm wide x 18 cm long, that penetrated into the right conchofrontal sinus from the caudal aspect of the frontal sinus on the midline to the level of the medial canthus of the right eye, 4 cm to the right of the midline (Fig 1). several detached fragments of frontal bone were visible within the conchofrontal sinus. an endoscopic evaluation of the nasal cavities revealed no abnormalities. apart from blood clots and bone fragments from the fracture, no abnormalities were observed during endoscopic examination through the wound into the conchofrontal sinus. corrective surgery was performed with the horse standing in stocks and sedated. The horse was medicated with 6.6 mg/kg gentamicin sulphate (Gentafuse; Butler) and 22,000 iu potassium penicillin (Pfizerpen; Pfizer) and initially sedated with 0.01 mg/kg detomidine (Domosedan; Pfizer) and 0.02 mg/kg butorphanol (Torbugesic; Fort Dodge), all administered intravenously. sedation was maintained throughout the procedure with detomidine and xylazine, administered intravenously to effect. The wound was cleaned with 4 per cent chlorhexidine and high-pressure lavage with physiological sterile saline.
