A vascularized preputial free flap for labial reconstruction in a dog
1Institute of Veterinary Clinical Sciences, School of Veterinary Medicine and Veterinary Teaching Hospital, National Taiwan University, Taipei, Taiwan, ROC.
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.
