目的:探讨一种更加有效的下齿槽神经阻滞麻醉的方法。方法:随机选取需翻瓣去骨法拔除下颌阻生第三磨牙患者150例。实验组50例,采用Gow-Gates法阻滞麻醉,对照一组50例,采用下颌支内侧隆突阻滞麻醉,对照二组在采用对照组一的方法注射后保留少量局麻药加用患牙颊侧近远中及舌侧三点浸润麻醉。采用VAS评分法观察疼痛情况。三组病例均使用阿替卡因肾上腺素注射液。结果:与对照一组相比,采用Gow-Gates法阻滞麻醉的病例疼痛明显减轻,但是与对照二组相比,该法没有明显优势。结论:传统的下颌支内侧隆突阻滞麻醉加用局部浸润麻醉可以有效提高下牙槽神经阻滞麻醉的成功率,达到与Gow-Gates阻滞麻醉相同的麻醉效果。
Objective: To explore a more effective method of inferior alveolar nerve block anesthesia. Methods: A total of 150 patients with mandibular impacted third molars were selected randomly. 50 cases in the experimental group were given Gow-Gates block anesthesia, 50 cases in the control group were treated with medial protuberance block of the mandibular branch. The control group 2 received a small amount of local anesthetic plus teeth Near the buccal side and lingual three-point infiltration anesthesia. VAS score was used to observe the pain situation. Three groups of patients were treated with articaine adrenaline injection. RESULTS: Compared with the control group, pain was significantly reduced in the Gow-Gates block anesthesia group, but there was no significant advantage compared with the control group. CONCLUSIONS: Traditional medial mandibular branch block anesthesia combined with local infiltration anesthesia can effectively improve the success rate of inferior alveolar nerve block anesthesia and achieve the same anesthetic effect as Gow-Gates block anesthesia.
