Plain-English summary
Five dogs with defects in their upper lips, often due to tumor removal, were treated using a surgical technique called a buccal transposition flap. This method helped to close the lip defects effectively, and all the flaps survived after surgery. While three dogs experienced some complications, like small openings between the mouth and nose or partial flap separation, the overall results were good, with satisfactory appearance and function for all the dogs.

Abstract
OBJECTIVE: To describe the technique and outcomes of the closure of maxillary lip defects using a buccal transposition flap and to identify potential routes of vascular supply to the flap. ANIMALS: Five dogs treated clinically and 1 cadaveric dog head. STUDY DESIGN: Short case series and cadaveric study. METHODS: A left maxillary labial defect and a buccal transposition flap were created on a cadaver head. Iodinated contrast was injected into the left common carotid artery and computed tomography was performed to assess the vascular supply. Medical records were reviewed for all dogs that underwent tumor excision with maxillary lip resection, reconstructed with a buccal transposition flap. RESULTS: The buccal transposition flap was perfused by branches of the angularis oris artery and superior labial artery. Five dogs were included in this study. All flaps survived. Three dogs developed postoperative complications, including oronasal fistula (n = 2) and partial flap dehiscence (n = 1). The cosmetic and functional outcomes were considered satisfactory in all cases. CONCLUSION: Buccal transposition flaps for the closure of large maxillary lip defects provided adequate functional and cosmetic outcomes. The buccal transposition flap had vascular contributions from the angularis oris artery and the superior labial artery.
