Objective:A retrospective study aimed to investigate the characteristics and prognosis of inflammatory sphenoid sinus diseases and discuss of endoscopic surgical techniques.Method:A total of 105 subjects with isolated inflammatory sphenoid pathologies were treated by endoscopic surgery,which included 41(39.0%) cases of fungal sinusitis,33(31.4%) mucocele,and 31(29.5%) sphenoiditis.They were evaluated by paranasalsinuse CT scan and all patients underwent endoscopic sphenoidsinus surgery under general anesthesia.Twenty cases were selected in Messerklinger,74 cases selected in Wingand,5 cases selected in Draf 3-like,5 cases selected in transphenoidal septum into the contralateral sphenoid sinus,and 1 case selected in trans-medial plate of pterygoid process approach.Result:The postoperative follow up from 6 to 27 months showed that sphenoid ostium were good in 96(91.4%) patients,stenosis in 5(4.8%) patients,and atresia in 4(3.8%)patients who need reoperation.Conclusion:Transnasal endoscopic sphenoidectomy should be the standard option for dealing with isolated inflammatory sphenoid diseases.The five different approaches would be selected according to the extension of the diseases and anatomic structure of the sphenoid sinus.
