Application of collagen matrix (DuraGen^®) to reduce subcutaneous emphysema in canine dorsal rhinotomy

抄録

This retrospective case study aimed to evaluate the efficacy of collagen matrix (DuraGen^®) in preventing subcutaneous emphysema, a common complication following dorsal rhinotomy. Six client-owned dogs diagnosed with nasal masses using computed tomography were included in this study. Dorsal rhinotomy was performed, and a collagen matrix was used to seal bone defects before fixation of the nasal bone flap. Following collagen matrix application, all dogs recovered without notable complications. These findings suggest that the collagen matrix is a reliable and safe intervention for mitigating subcutaneous emphysema after dorsal rhinotomy.
