For around 50 years, various approaches to the vidian neurectomy have been advocated. This indicates that there is no single surgical technique that is superior to all others. In this report, we analyze the included angle between the posterior end of middle turbinate and the anterior opening of the vidian canal. The aim of this paper is to use preoperative CT scanning to find a key anatomical structure to predict the feasibility of the vidian neurectomy. A retrospective research was performed. A total of 63 patients with 106 endoscopic vidian neurectomies between September 2006 and April 2010 were selected. The study population included 50 men and 13 women, with a mean age of 28. A paranasal sinus CT scan was obtained and analyzed. The included angle was measured and compared to the operating success rates. In the successful group (78 sides, 73.58%), the included angle from axial and coronal CT imaging was 30.2 ± 4.9° and 26.4 ± 9.1°, respectively. In the 28 failed sides (26.42%), the value was 33.8 ± 4.8° and 44.3 ± 8.1°, respectively. Statistical analysis confirmed that the difference between those two groups was significant (P < 0.05). The present study reports the relationship between the vidian canal and the middle turbinate, which is represented by their included angle. The findings support the decision to intervene the surgical side with a smaller angle, because of the significantly higher success rate.
50 年来，人们一直提倡各种不同的翼管神经切断术方法。这表明没有一种单一的手术技术优于其他技术。在本报告中，我们分析了中鼻甲后端与翼管前口之间的夹角。本文的目的是使用术前 CT 扫描来寻找一个关键的解剖结构，以预测翼管神经切断术的可行性。这是一项回顾性研究。共选择了 2006 年 9 月至 2010 年 4 月期间接受 106 例内镜下翼管神经切断术的 63 例患者。研究人群包括 50 名男性和 13 名女性，平均年龄为 28 岁。获取并分析鼻窦 CT 扫描。测量并比较了夹角与手术成功率。在成功组（78 侧，73.58%）中，轴位和冠状位 CT 成像的夹角分别为 30.2±4.9°和 26.4±9.1°。在 28 例失败的侧（26.42%）中，该值分别为 33.8±4.8°和 44.3±8.1°。统计学分析证实两组之间的差异具有统计学意义（P<0.05）。本研究报告了翼管和中鼻甲之间的关系，以它们的夹角表示。这一发现支持了这样一种决策，即对于夹角较小的手术侧进行干预，因为手术成功率显著提高。
