Summary
This study demonstrates endoscopy-assisted dacryocystorhinostomy as an effective minimally invasive treatment for canine nasolacrimal duct cysts. The technique successfully resolved clinical signs and improved cosmetic outcomes in a dog.
Area of Science:
- Veterinary Ophthalmology
- Minimally Invasive Surgery
- Endoscopic Procedures
Background:
- Nasolacrimal duct cysts (dacryocysts) can cause chronic epiphora and secondary infections in dogs.
- Traditional surgical approaches may be invasive and carry risks of complications.
Observation:
- A 4-year-old female American Staffordshire Terrier presented with chronic epiphora and nasal swelling due to a nasolacrimal duct cyst.
- Computed tomography revealed a cystic lesion with extensive nasal extension and obstructive frontal sinusitis.
Findings:
- Endoscopy-assisted dacryocystorhinostomy was performed using a 2.7 mm endoscope and arthroscopic cannula.
- A transcutaneous approach allowed for dacryocystorhinostomy, and a frontal sinus trephination facilitated lavage.
- Postoperative follow-up at 10 days and 17 months showed complete resolution of clinical signs and excellent cosmetic results.
Implications:
- Endoscopy-assisted dacryocystorhinostomy offers an effective, minimally invasive surgical option for canine nasolacrimal duct cysts.
- This technique can lead to successful management of complex dacryocyst cases with favorable outcomes.
- Further research may explore the broader application of this endoscopic approach in veterinary ophthalmology.
