Purpose
To describe the use of a subdermal plexus transposition skin flap sparing the eyelid margin following excision of an eyelid mast cell tumour in a dog.
Methods
A 4-year-old neutered female Golden Retriever was presented to the Ophthalmology Service of the University of Helsinki Veterinary Teaching Hospital for management of an upper eyelid tumour of 5mm in diameter. Cytological diagnosis was consistent with a low-grade cutaneous mast cell tumour. Surgical resection with curative intent was performed. The tumour was excised en bloc with anatomical margins including one fascial plane and lateral margins of 20mm except towards the eyelid margin, where 5mm of the eyelid margin width was spared along a 10mm section, allowing for a minimum of 15mm lateral margins from the tumour. The defect was reconstructed with a midline-based subdermal plexus transposition skin flap with a 90-degree rotation.
Results
Histopathology was consistent with a low-grade cutaneous mast cell tumour excised with clean margins. Short-term complications included lagophthalmos secondary to transection of the orbicularis oculi and levator anguli oculi medialis muscles. Long-term complications included trichiasis easily managed with grooming. With time, successful blinking returned through compensation from the lower eyelid. No local tumour recurrence was noted during a 9-month follow-up period.
Conclusion
Preservation of a narrow portion of the eyelid margin utilising a subdermal plexus transposition skin flap may be a viable option for surgical excision of upper eyelid neoplasia. An anatomical and reasonably functional eyelid resulted with no major complications.
