Abstract: introduction: the lowered temporal meninges and/ or anterior sigmoid sinus are contiditions that can determine surgical difficulties in performing mastoidectomy. Objective: to correlate in the tomography the extent of the prolapse of the sigmoid sinus and of temporal meninges with the surgical difficulty in the mastoidectomy. http://viagraforsaleovernightcfs.com Method: the tomographic measurements of prolapse sigmoid and of temporal meninges were correlated with the presence or non-presence of the surgical difficulty observed during the mastoidectomy procedure in patients with ostomatoiditis chronic (n=30). generic viagra from us pharmacy Form of study: contemporary cohort transverse. Results: in 10 patients were observed surgical difficulty distributed as: due to prolapse of the sigmoid sinus (n = 2) or temporal meninges prolapse (n = 7) or both (n = 1). viagra vs viagra buy online In patients in which the surgical difficulty was due to sigmoid sinus prolapse, the tomography distance of the anterior border of the sigmoid sinus to posterior wall of external auditory canal was lower than 9 mm.
