Cutaneous arterial blood supply to the temporal region was evaluated in 8 dogs and 8 cats. Subtraction radiography and angiography of the carotid and superficial temporal arteries were used in 4 dogs and 4 cats to determine arterial blood supply to the temporal region and frontalis muscle. A myocutaneous axial pattern flap based on the superficial temporal artery and frontalis muscle may be indicated for cosmetic reconstruction in dogs and cats following surgical resection of neoplastic lesions or traumatic wounds in the maxillofacial region. The frontalis muscle was identified as the thin subcutaneous continuation of the platysma muscle extending cranially and rostrally. Dissection of the temporal region in 4 dogs and 4 cats revealed the subcutaneous location of the superficial temporal artery as it continues rostrally from the caudal aspect of the zygomatic arch.
A 75-year-old male with angina and a squamous carcinoma of the left lower lobe underwent a single-stage procedure for the treatment of these lesions. Through a left postero-lateral thoracotomy, a left lower lobectomy was performed with systematic nodal dissection including the subcarinal and paraaortic lymph nodes. A reversed saphenous vein segment was used to bypass the left anterior descending artery from the ascending aorta without cardiopulmonary bypass.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
