目的:本研究的目的是回顾性评估射频体积组织减少术(RFVTR)对多水平手术(MLS)中短头犬的肥厚性鼻甲和临床结局的影响。
方法:临床回顾性多中心研究。
方法:132只客户拥有的短头犬。
方法:用RFVTR作为上气道MLS的一部分,对132只患有高度短脑阻塞气道综合征(BOAS)和肥厚性鼻甲的短头犬进行治疗。在RFVTR之前和之后6个月,通过计算机断层扫描(CT)和前/逆行鼻镜检查评估鼻内梗阻。临床记录,我们回顾了CT图像和鼻镜检查视频,并使用标准化问卷评估了临床演变.对数据进行半定量评分。
结果:在这项研究中,132名患者被纳入120周的随访期。RFVTR导致轻微并发症,包括所有狗术后第一周的浆液性鼻腔分泌物,24.3%的患者在治疗后3-8周出现间歇性鼻塞。对33例患者进行了鼻镜检查和CT随访。治疗后6个月,鼻内空域增加(p=0.002),粘膜接触点的存在和总量减少(p=0.039)。
结论:MLS与RFVTR在6个月的随访检查中导致鼻甲体积显着减少,并在120周的长期内显着临床改善。这表明RFVTR作为BOAS犬鼻内阻塞的鼻甲保留治疗的可行性。
结论:RFVTR是一种用于BOAS犬鼻内阻塞的微创鼻甲成形术技术,可以包括在MLS中,而不会增加并发症的发生率。
OBJECTIVE: The objective of this study was to retrospectively assess the effect of Radiofrequency Volumetric Tissue Reduction (RFVTR) on hypertrophic
turbinates and clinical outcome in brachycephalic dogs when included in multi-level surgery (MLS).
METHODS: Clinical retrospective multicenter study.
METHODS: 132 client-owned brachycephalic dogs.
METHODS: 132 brachycephalic dogs with high-grade Brachycephalic Obstructive Airway Ayndrome (BOAS) and hypertrophic
turbinates were treated with RFVTR as part of MLS of the upper airways. Intranasal obstruction was evaluated by computer tomography (CT) and antero-/retrograde rhinoscopy before and 6 months after RFVTR. The clinical records, the CT images and the rhinoscopy videos were reviewed and clinical evolution was evaluated using a standardized questionnaire. The data was scored semi-quantitatively.
RESULTS: In this study, 132 patients were included for a follow-up period of 120 weeks. RFVTR resulted in minor complications, including serous nasal discharge within the first postoperative week in all dogs, and intermittent nasal congestion between 3-8 weeks after treatment in 24.3% of the patients. Rhinoscopy and CT follow-ups were available for 33 patients. Six months after treatment intranasal airspace was increased (p = 0.002) and the presence and overall amount of mucosal contact points was reduced (p = 0.039).
CONCLUSIONS: MLS with RFVTR led to a significant reduction in turbinate volume at the 6-month follow-up examination and significant clinical improvement over a long-term period of 120 weeks. This suggests the viability of RFVTR as a turbinate-preserving treatment for intranasal obstruction in dogs with BOAS.
CONCLUSIONS: RFVTR is a minimally invasive turbinoplasty technique for intranasal obstruction in dogs with BOAS and can be included in MLS without increasing complication rates.
