A vascularized preputial free flap for labial reconstruction in a dog.

Objective: To describe the clinical application of a vascularized preputial free flap in the reconstruction of a large facial-labial defect.

Study Design: Case report.

Animals: An adult neutered male mongrel dog with a large left facial-labial defect.

Methods: A preputial free flap was created by elevating the cranial part of the prepuce, using the ipsilateral caudal superficial epigastric vessels as a vascular pedicle. The flap was transferred to the facial-labial defect and the donor vessels anastomosed to the sublingual artery and vein, using standard microvascular technique.

Results: The free flap survived, leading to good cosmetic and functional outcomes. No major complications were encountered at either the donor or recipient sites after 2 years of follow-up.

Conclusion: Vascularized preputial free flaps can be used to manage composite facial and oral cavity defects involving large areas of skin and mucosa.
