目的:探讨鼻内镜手术中更为完善的上颌窦自然孔开窗术。方法:采用自身配对,研究128例病变相近的慢性鼻窦炎,鼻息肉患者,一侧窦口尽量扩大,另一侧常规扩大,观察两组术后窦口开放情况。结果:术中尽量扩大窦口一侧,窦口开放率96.09%(123/128),常规扩大侧窦口开放率为81.25%(104/128),两组上颌窦口开放率经统计学检验,差异有统计学意义(P<0.05)。结论:鼻内镜手术中,尽量扩大上颌窦开窗口可提高上颌窦口开放率及开放良好率。
Objective: To explore the more perfect maxillary sinus natural orifice fenestration in endoscopic sinus surgery. Methods: One hundred and eighty patients with chronic sinusitis and nasal polyps were studied by self-pairing. One side of the sinus ostium was enlarged as much as possible and the other side was routinely expanded. The ostium was opened after operation. Results: The opening of the ostium was 96.09% (123/128). The open rate of the normal ostium was 81.25% (104/128). The open rate of the maxillary ostium in both groups was statistically tested , The difference was statistically significant (P <0.05). Conclusion: Endoscopic sinus surgery to maximize the open maxillary sinus can increase the rate of open maxillary ostium and open good rate.
