CT在上颌窦囊肿切除术式选择中的应用评价

CT application in the selection of methods of maxillary sinus cystectomy

目的评价鼻窦薄层CT在上颌窦囊肿切除手术策略选择中的应用效果。方法回顾性分析2018年3月~2021年3月上颌窦囊肿患者80例(90窦)病历资料,术前均行鼻窦CT检查并判读,按囊肿不同的起源分类后,采用相应的手术径路切除病变。结果分析鼻窦CT,囊肿起源于上颌窦前壁21窦,上壁8窦,底壁1窦,内侧壁25窦,外侧壁17窦。行扩大自然窦口径路26窦,下鼻道开窗径路20窦,泪前隐窝径路44窦。手术均实现全切,无术后出血,溢泪,前鼻孔狭窄等并发症。随访期间无复发。结论术前鼻窦CT对囊肿起源位置的确定可以为合适的手术径路选择提供重要依据。

Objective To evaluate the effect of CT of sinuses in the selection of surgical strategies for maxillary sinus cystectomy.Methods The medical records of 80 patients with maxillary sinus cysts(90 sinuses)from March 2018 to March 2021 were retrospectively analyzed.Before surgery,sinus CT examination and interpretation were performed.After classification according to different origins of cysts,corresponding surgical approaches were used to excise the lesions.Results The sinus CT analysis showed that the cysts originated from 21 sinuses on the anterior wall of the maxillary sinus,in the upper wall of 8 sinuses,1 in the bottom wall,25 in the medial wall,and 17 in the lateral wall.26 enlarging the natural ostium of maxillary sinus route were applied.Inferior meatal fenestration route were applied to 20 sinus,anterior lacrimal recess route were in 44 sinus.All operations achieved total resection without postoperative bleeding,epiphora,anterior nostril stenosis and other complications.There was no recurrence during follow-up.Conclusion Preoperative sinus CT to identify the origin of cyst can provide an important basis for the selection of appropriate surgical approach.
