A 4-year-old spayed female French Bulldog was referred for treatment of a suspected right-sided nasal angiofibroma associated with a 4-month history of unilateral nasal discharge and stertor.
The dog appeared healthy other than right-sided mucoid debris and decreased airflow through the right naris. The dog was anesthetized, and a large intranasal mass was observed obstructing the right nasal passage and abutting the nasal septum.
A lateral rhinotomy was performed, and rigid endoscopes (0° and 30°) were used to examine the right nasal cavity. The mass filled the anterior aspect of the nasal cavity and involved a portion of the nasal turbinates with some erosion. A coblation unit was used to ablate tumor tissue laterally to remove the tumor in piecemeal fashion. Recovery was routine with only minor epistaxis after surgery, and the dog was discharged the next day. Eight months after surgery, follow-up CT revealed right-sided nasal turbinate and conchal atrophy consistent with prior mass ablation. No macroscopic recurrence was detected, and the owners reported only rare, clear rhinorrhea.
Findings suggested that coblation may be an alternative to radiation therapy for vascular tumors with minimal invasion and low metastatic potential.
一只4岁已绝育的雌性法国斗牛犬因疑似右侧鼻血管纤维瘤前来接受治疗，该犬有4个月单侧鼻分泌物和鼾症病史。
除右侧有黏液样分泌物以及右侧鼻孔气流减少外，该犬看起来健康。对该犬实施麻醉后，观察到鼻腔内有一巨大肿物阻塞右侧鼻道并紧贴鼻中隔。
实施了外侧鼻切开术，并使用硬性内窥镜（0°和30°）检查右侧鼻腔。肿物充满鼻腔前部，累及部分鼻甲并有一些糜烂。使用低温等离子消融设备从侧面消融肿瘤组织，以逐块切除肿瘤。恢复过程常规，术后仅有少量鼻出血，该犬于次日出院。术后8个月，随访CT显示右侧鼻甲和鼻甲壳萎缩，与之前的肿物消融相符。未检测到肉眼可见的复发，主人报告仅偶尔有清亮鼻漏。
研究结果表明，对于侵袭性极小且转移潜能低的血管性肿瘤，低温等离子消融可能是放射治疗的一种替代方法。
