Surgical management of refractory nasal aspergillosis using iodine cadexomer dressings in three dogs.

BACKGROUND

This case series describes surgical management of nasal aspergillosis refractory to conventional medical management or with evidence of cribriform plate osteolysis in three dogs.

METHODS

All dogs had surgical debridement of mucosa, nasal turbinates and necrotic debris via dorsal sinusotomy/rhinotomy. Sinuses were packed with iodine cadexomer-impregnated bandages for several weeks and affixed with tie-over bandages. Bandage changes were performed under sedation in 2/3 cases. Once mature granulation tissue covered all exposed bone, the tie-over bandages were removed and the sinusotomy/rhinotomy closed by apposing the skin edges.

CONCLUSION

This technique was well tolerated, effective and afforded a cure in all three patients. It should be considered in cases of cribriform lysis or lack of clinical response to conventional medical management.
