进一步认识孤立性蝶窦占位性病变，提高对其诊断和治疗水平。方法：在鼻内窥镜下摘除蝶窦囊肿２０例，行蝶窦探查术６例，经鼻外径路摘除囊肿３例，前颅底径路病变切除＋视神经减压术１例。结果：２４例随访０．５～４年无复发，１例术后不久囊肿复发，１例术后１年复发再次手术后随访１年无复发，１例正在放疗中，３例失访。结论：由于本病早期无独特症状，ＣＴ检查对诊断本病有较大价值，且对手术有一定指导意义；鼻内窥镜手术对治疗蝶窦良性占位性病变有显著的优越性。
To further understand the solitary sphenoid space occupying lesions, improve their diagnosis and treatment. Methods: 20 cases of sphenoid cysts were removed under nasal endoscopy, 6 cases underwent sphenoid sinus exploration, 3 cases were removed by nasal approach, 1 case was excised by anterior skull pathology and decompression of optic nerve. Results: 24 cases were followed up for 0.5 to 4 years without recurrence. One case had cyst recurrence shortly after operation, and one case had recurrence one year after operation. There was no follow-up one year follow-up after surgery. One case was radiotherapy and three cases were lost. Conclusion: Because of the early symptoms of this disease are not unique, CT examination of the diagnosis of the disease have great value, and the operation has some guiding significance; nasal endoscopic surgery for the treatment of benign spondylomas lesions have significant advantages.
