鼻内镜下上颌骨囊肿开放术

目的:探讨鼻内镜下上颌骨囊肿开放术的有效性和可行性。方法:对13例侵犯上颌窦或鼻腔底的上颌骨囊肿在鼻内镜下行上颌骨囊肿开放术,即行鼻内镜下囊肿下鼻道或鼻腔底开放术,囊肿囊壁被全部或部分切除。结果:随访6～36个月,13例患者未出现面部隆起、鼻塞及鼻腔溢液等症状,囊肿无复发。结论:鼻内镜下上颌骨囊肿开放术适用于侵犯上颌窦或鼻腔底的上颌骨囊肿,较传统手术创伤小,简单高效,受侵牙齿可尽量保存。

Transnasal endoscopic marsupialization for treatment of maxillary cysts

Objective:To evaluate the effectiveness and usefulness of transnasal endoscopic surgery for the treatment of maxillary cysts.Method:Transnasal endoscopic surgery was performed in 13 patients with maxillary cysts that extended to the maxillary sinus or the nasal bottom.Five patients had a radicular cyst,three patients had a dentigerous cyst,three patients had a nasolabial cyst and two patients had a median cyst.After the resection of anterior edge of the inferior turbinate or the nasal bottom,the lateral wall of the inferior nasal meatus was opened.Then,the cyst wall of the maxillary sinus was partially or completely removed under the endoscope.Result:The cyst walls were completely or partial removed in 13 patients with maxillary cysts.There were no complications,and postoperative courses were uneventful.The follow-up period ranged from 6 to 36 months,and no recurrence were noted in any of the cases.Conclusion:Endoscopic transnasal surgery for the maxillary cyst is less invasive than conventional dental approach,and most of the affected teeth can be preserved.This technique appears to be a simple and highly effective surgical treatment for the treatment of patients with maxillary cysts that extend to the maxillary sinus or the nasal bottom.
