Oronasal fistula is a relatively common complication associated with maxillary canine tooth extraction, problematic healing of maxillectomy, and repair of secondary cleft palate in small animals. Regardless of the clinical scenario associated with oronasal fistula, therapy requires surgical treatment. Principles for surgical repair of oronasal fistula include development of mucosal flaps with excellent vascular supply to transpose over the defect to restore continuity of the nasal and oral cavities. The specific surgical technique may vary but includes either single or double mucosal flaps. Oronasal fistula refractory to multiple attempts at surgical repair may be obturated by using a prosthodontic device.
口鼻瘘是小动物上颌犬齿拔除、上颌骨切除术愈合不良以及继发腭裂修复术后相对常见的并发症。无论与口鼻瘘相关的临床情况如何，治疗都需要手术治疗。口鼻瘘手术修复的原则包括制作血供良好的黏膜瓣，将其转移覆盖在缺损处，以恢复鼻腔和口腔的连续性。具体的手术技术可能有所不同，但包括单黏膜瓣或双黏膜瓣。经多次手术修复仍难治的口鼻瘘，可使用修复装置进行阻塞治疗。
