Brief overview about Canine/Salivary Mucocele Excision and Handling

1. Salivary Mucocele

2. Salivary Mucocele aka sialocele, salivary cyst,
honey cyst
A salivary mucocele is a collection of saliva that
has leaked from a damaged salivary gland or duct
and is surrounded by granulation tissue

3. Terms
•Cervical Mucocele
•Sublingual Mucocele
•Pharyngeal Mucocele
•Zygomatic Mucocele
•Complex Mucocele
•Marsupialisation

6. Tumour vs Cyst vs Abscess vs
Mucocele

7. Etiology
Bone eating, Trauma

8. Physical Examination
• Soft and Fluctuant
• Side affected understood by laying animal in dorsal
recumbancy

9. Diagnostic Imaging
• Sialography difficult
• Perform cross-sectional imaging to understand better
• Do thoracic radiography if metastasis growth is suspected

10. Laboratory Findings
• Laboratory abnormalities are rare
• Salivary gland function and duct patency can be evaluated by
placing a drop of topical ophthalmic atropine solution on the
tongue to stimulate saliva flow; however, it may be difficult to
distinguish flow from individual ducts
• Aspiration of a clear, yellowish, or blood-tinged, ropy, mucoid
fluid with a low cell count is consistent with saliva. Staining a
smear with a mucus-specific stain such as periodic acid-Schiff
(PAS) confirms the presence of saliva

11. Medical Management

12. Medically:
• Ineffeicent
• Actual cause not removed
• The fluid is aspirated
• Swelling comes again!
• Anti-inflammatory don’t improve rather comlicates

13. Surgical Management

14. Anesthesia
• Gaseous Anesthesia
• Induction Propofol @2-4mg/kg
• Maintenance Isoflurane @

15. Surgical Anatomy

18. Surgical Technique
• Mandibular and Sublingual Salivary Gland Excision

27. Surgical Technique
• Zygomatic Gland Excision

29. Surgical Technique
• Parotid Gland Excision

31. POSTOPERATIVE CARE AND
ASSESSMENT
• Change dressing
• Soft food
• Penrose drain taken care of

32. Complications
• Regional Lymph Node
• Opposite Side surgery: misdiagnosis
• Seroma

33. Prognosis
• Excellent
• If everything diagnosis and excision are accurate
