[Treatment of isolated sphenoid sinus disease by trans-basal lamella approach to sphenoid sinus].

The aim of this study is to investigate the safety and practicability of the trans-horizontal basal lamella sphenoidotomy approach in the treatment of the isolated sphenoid sinus disease.Sphenoidotomy and posterior-ethmoidotomy by endoscopic trans-horizontal basal lamella approach were performed in 64 patients who were diagnosed with isolated sphenoid sinus.The horizontal course of the basal lamella is perforated and opened,and the superior meatus is entered.Then sphenoidotomy and posterior-ethmoidotomy were performed by the landmark superior turbinate.All patients were successfully operated without serious complications.After 1 year follow-up,no recurrence were found in 30 cases of fungal sphenoid sinusitis patients,12 cases of chronic sphenoidal sinusitis patients,13 cases of sphenoid sinus cyst patients,6 cases of sphenoid sinus polyps patients,and 3 cases of sphenoid sinus inverted papilloma patients.The ostium of sphenoid sinus maintained well without atresia.Trans-horizontal basal lamella approach to sphenoid sinus is safe and effective in the treatment of isolated lesion,and the opening of sphenoid sinus and posterior-ethmoid sinus were enlarged better by this technique.
