“…Methods used for orbital reconstruction in human craniomaxillofacial surgery are many and varied. They include the use of synthetic allografts such as polytetrafluoroethylene (Teflon), silicone, or titanium mesh implants; local soft‐tissue flaps using the masseter or temporalis muscle; nonvascularized bone grafts from the rib, calvarium, or iliac crest; vascularized osteocutaneous free flaps such as the free scapular flap; or distant free muscular flaps using the latissimus dorsi or rectus abdominus, which require microvascular reanastomosis techniques rarely used in veterinary surgery.…”

Objective: To describe a novel surgical technique for ventral orbital reconstruction after ventral orbitectomy by using a temporalis fascia transposition flap. Study design: Case report. Methods: A 7-year-old, spayed female Boston terrier was treated for multilobular osteochondrosarcoma arising from the cranial aspect of the left zygomatic arch, causing asymmetry of the face and mild exophthalmos of the left eye. A ventral orbitectomy with a wide surgical excision (including the cranial aspect of the zygomatic bone, the medial aspect of the lacrimal bone, and the dorsal aspect of the maxilla) was performed with preservation of the left eye. To support and maintain the left eye in a normal position, a temporalis fascia transposition flap was elevated and used. No complications occurred during the procedure. Results: Thirteen days after surgery, the referring veterinarian reported no complications. Complete excision was confirmed on histopathology. Eighty-three days after surgery, the dog remained asymptomatic with only mild epiphora of the left eye. Follow-up information from the owner 11 months after surgery indicated that the dog was asymptomatic with minimal ventral globe deviation. Conclusion: Additional ventral support of the globe after ventral orbitectomy via a temporalis fascia transposition flap resulted in an excellent functional and cosmetic outcome. Clinical significance: A temporalis fascia transposition flap can be used to reconstruct the ventral aspect of the orbit in dogs.

“…A masseter muscle flap has been used for facial reconstruction in man and dogs . In man, with a superiorly based masseter muscle flap, the masseter muscle is attached and pivots at the zygomatic arch of the maxilla . This technique is considered a relatively safe, single‐stage procedure and is easily adaptable for the repair of various defects because of flexibility in the movement of the pedicle.…”

“…Restriction of mouth opening is reported after superiorly based masseter flaps in man and is thought to occur due to muscle contraction of the masseter muscle flap. This complication was not observed in our case, possibly because of a different orientation of the muscle flap in the horse, which was reflected dorsally and sutured to the maxilla, where contraction of the muscle flap would be unlikely to cause closing of the mouth.…”

“…The masseter muscle is used to reconstruct the caudal maxilla and ventral orbital floor in man and in dogs because it provides a bulky flap, and the procedure is relatively easy and safe . The masseter muscle is large and consists of two layers in the horse, and the superficial layer of the muscle potentially could be useful to close large sinocutaneous fistulas; however, its use has not been reported.…”

Objective: To describe a new technique to repair a sinocutaneous fistula with a masseter muscle transposition flap. Study design: Case report.Animal: One 13-year-old thoroughbred stallion. Methods: One 13-year-old stallion with a 3.5 × 6-cm sinocutaneous fistula over the right caudal maxillary sinus was treated with a transpositional masseter muscle flap. This repair consisted of a commercial wound matrix dressing placed directly over the hole in the maxilla and secured with suture material; a cancellous bone graft collected from the right tuber coxa placed on the dressing; and a portion of the superficial layer of the masseter muscle, with its pedicle at the facial crest, transposed dorsally over the bone graft, followed by a rotational skin flap with skin rostral to the fistula to close the defect.Results: Seroma formation and dehiscence of the skin flap occurred, but the transposed muscle flap survived, and the technique resulted in successful closure of the sinocutaneous fistula with excellent cosmetic and functional outcome. Conclusion: A chronic maxillary sinocutaneous fistula was successfully treated by using a transposition flap of the masseter muscle and a rotational skin flap with minor complications.Clinical impact: Transposition of the superficial layer of the masseter muscle should be considered for a repair of large maxillary sinocutaneous fistulas in horses.

“…Due to the proximity of the masseter muscle to the caudal maxilla and ventral orbital floor, it has already been used in humans to stabilize the ventral orbit . The masseter muscle consists of superficial, middle, and deep layers that are covered by a strong glistening aponeurosis and is positioned laterally on the ramus of the mandible of the dog.…”

Loss of the caudal maxilla and ventral orbit after tumor resections can have negative functional and aesthetic influences on the eye involved. This article reports on a case of a caudal maxillary acanthomatous ameloblastoma involving the ventral orbit that was resected and stabilized with a masseter muscle flap. The masseter muscle flap was generated from the superficial belly of the masseter muscle in order to close a defect in the orbital rim, created by a caudal maxillectomy.None of the published complications such as enophthalmos, excessive lacrimation, globe deviation or strabismus were noted, eight months following the procedure. The only clinical sign present at the time of re-evaluation was mild lacrimation. The authors propose the use of a masseter muscle flap as a viable technique in stabilizing the ventral orbit after caudal maxillectomy and ventral orbitectomy, preventing the complications associated with this surgery.
