Lateral sinus thrombosis as a complication of chronic suppurative otitis media.

18 cases of lateral sinus thrombosis are reported. All cases occured as a complication of attico-antral type of chronic suppurative otitis media. LST was found alone in 22.2% cases. LST was found associated with peri-sinus abscess (77.8%), meningitis (38.9%) and cerebellar abscess (16.6%). Surgical treatment consisted of radical mastoidectomy with incision of lateral sinus and suction of its contents in all cases; while in 16.7% cases sinuses were also obliterated after instituting free bleeding at LST site. Death occured in 5 cases (27.7%). The mortality for LST, while greatly reduced due to antibiotics, still remains significant. [ABSTRACT FROM AUTHOR]
