We developed a new technique, the medial orbital pericone local anesthetic block, that surgeons can use a secondary block when inferotemporal retrobulbar or peribulbar/periocular injection of local anesthetics results in incomplete anesthesia. Unlike secondary local injections placed in the superonasal quadrant of the orbit, our technique injects the anesthetic into the fat compartment of the nasal side of the globe, a site that is relatively avascular and lacks vital anatomic structures. In more than 15,000 patients, this method proved an effective, safe means of secondary block and promoted orbicularis oculi muscle akinesia.
我们开发了一种新技术，即眶内侧锥周局部麻醉阻滞，当颞下球后或球周/眼周局部麻醉注射导致麻醉不完全时，外科医生可将其用作辅助阻滞。与在眼眶鼻上象限进行的辅助局部注射不同，我们的技术是将麻醉剂注射到眼球鼻侧的脂肪间隙，该部位相对无血管且缺乏重要的解剖结构。在超过15000例患者中，该方法被证明是一种有效、安全的辅助阻滞手段，并可促进眼轮匝肌运动不能。
