作者回顾了慢性上颌窦炎的手术治疗,指出基于病理生理知识和技术的发展、手术器械的改进,鼻内窥镜鼻囱门(nasal fontanel)手术可以减少和防止如眼底损伤和蝶腭动脉严重出血等手术并发症。由于上颌窦炎粘膜的肿胀或鼻腔局部病变如鼻炎、额筛窦炎等很易阻塞狭窄的自然窦口,影响引流。在正常中鼻道解剖,筛突及钩突的背尾部将上颌窦裂孔前后分为鼻前后囱门,此处无骨质,仅鼻腔与上颌窦二层粘膜使二者相隔,所以可在鼻内窥镜下通过此处手术形成一个新的上颌窦引流口,它比在下鼻道开窗优越,因为窦腔内粘膜纤毛功能在正常情况下是将分泌物向中鼻道引流而不是向下鼻道引流,中鼻道膜性部分的鼻 The authors reviewed the surgical treatment of chronic maxillary sinusitis and pointed out that based on the development of pathophysiological knowledge and techniques, improvements in surgical instruments, endoscopic nasal fontanel surgery can reduce and prevent severe ocular fundus injury, Bleeding and other surgical complications. Due to the swelling of the maxillary sinusitis mucosa or nasal local lesions such as rhinitis, frontal ethmoid sinus and other easy to block the narrow natural sinus ostium, affecting drainage. In the normal middle meatus anatomical, mesial and uncinate process, the caudal part of maxillary sinus is divided into front and back hilar anterior and posterior fissure gate, where there is no bone, only the nasal cavity and maxillary sinus mucosa so that the two separated, so in the nose Under the endoscope, a new maxillary sinus drain is created by surgery here, which is superior to the opening of the inferior nasal passages because mucociliary function in the sinus cavity normally drains secretions toward the middle nasal passages rather than downward Nasal drainage, nasal membrane in the middle part of the nasal
