电磁跟踪系统、光学数字系统及机械臂系统等图像导航系统,均有助于内镜鼻窦手术安全、顺利进行。由于鼻腔内的气体不传导超声波,通过超声检查很难获得鼻窦的清晰图像。用“Noda气囊”堵住后鼻孔,对鼻腔内安全注水,可使鼻腔内超声检查更为有效。为了确定超声检查的可行性,该作者对15例慢性鼻窦炎患 Electromagnetic tracking systems, optical digital systems and robotic systems such as image navigation systems, are helpful to endoscopic sinus surgery safe and smooth. Since the gas in the nasal cavity does not transmit ultrasound, it is difficult to obtain a clear image of the sinus by sonography. With the “Noda balloon” to block the posterior nostrils, the safe nasal irrigation, intranasal ultrasound can make more effective. In order to determine the feasibility of ultrasonography, the authors of 15 cases of chronic sinusitis
