The treatment of chronic sinusitis in six cats by ethmoid conchal curettage and autogenous fat graft sinus ablation.

Six cats with chronic recurrent rhinitis and frontal sinusitis were treated by surgical ablation of their frontal sinuses by the implantation of autogenous fat grafts and curettage of the remaining ethmoid conchae. Deep nasal bacterial cultures and skull radiographs were performed before surgery. Excellent results were achieved in four of six cats and there was significant improvement in two of six cats. Median follow-up time was 15 months. Subcutaneous emphysema over the temporal area was managed by needle aspiration and bandaging. Frontal sinus ablation with autogenous fat graft in combination with ethmoid conchal curettage appears to be an effective treatment for chronic sinusitis in cats.
