目的:探讨误入上颌窦内的牙根,经上颌窦前壁开窗辅助鼻内窥镜取出拔牙断根的临床疗效。方法:对在拔牙过程中造成断根误入上颌窦的6例患者中的6个断根,经口内切口上颌窦前壁开窗,辅以鼻窦内窥镜直视下取出断根。结果:6例患者6个误入上颌窦的断根通过冲洗或夹取均快速、完整取出,该手术方法视野开阔、清晰,组织损伤小,创口愈合良好,术后无不良反应发生。结论:采用经上颌窦前壁开窗辅助鼻内窥镜直视下取出误入上颌窦内的断根手术式可以方便、快捷地取出断根,手术时间短、创伤小。
OBJECTIVE: To investigate the clinical effect of root extraction into the root of maxillary sinus and extraction of the root of extraction through the nasal endoscope through the anterior wall of maxillary sinus. Methods: 6 out of the 6 patients who had strayed into the maxillary sinus during tooth extraction were dipped into the anterior incision through the mouth of the maxillary anastomosis, assisted by endoscopic sinus surgery. Results: Six of the 6 patients who had strayed into the maxillary sinus were quickly and completely removed by washing or clamping. The method had wide field of vision, clearness, small tissue damage and good wound healing without any adverse reaction. CONCLUSION: The method of removing the root of the maxillary sinus and removing the root of the maxillary sinus can be easily and quickly removed with the help of nasal endoscope through the window of the anterior wall of the maxillary sinus. The operation time is short and the trauma is small.
