Surgical treatment using a disposable biopsy punch was applied for aural hematoma in 10 dogs and a cat. The 4-mm or 6-mm holes in diameter made on the skin into the auricle cartilage at the site of aural hematoma using a disposable biopsy punch produced good drainage for several days. All cases healed functionally and cosmetically. These results suggest that it was a suitable method for the treatment of aural hematoma.
Surgical treatment was tried in a dog with medial patellar luxation in which trochleoplasty had been unsucsessfully done twice in the past. The trochlear sulcus was erosive and covered with the inflammatory tissues. Patella luxation was treated by reconstructing the trochlear sulcus using a cartilage flap obtained from the lateral condyle of the femur, combined with correction of the alignment of the soft tissue from the rectus femoris muscle to the tibial crest. This procedure allowed the trochlear to be covered with the new hyaline cartilage. Excellent function was restored in about 3 months after surgery. Therefore, it was considered that this surgical technique could be an effective reconstructive method of the trochlear cartilage before considering the adaptation of arthrodesis.
