In Britain, only six cases of lateral sinus
thrombosis and one case of Bezold's abscess have been reported in the literature in the last decade of the 20th century .
However, detailed evaluation was performed when his general condition deteriorated and he had nausea and vomiting after 24 hours of treatment, and the diagnosis was meningitis and lateral sinus
on the outer cortex of the lateral sinus
wall (Figure 4).
In this study the most common places of thrombosis were superior sagittal sinus (71.4%) and right lateral sinus
(57.1%); this is totally analogous with the results of studies conducted in Namazi Hospital in shiraz and Brazil.11,13 In performed study in the United States the most involved places were lateral and sigmoid sinuses.2
The authors have used the Low Window Sinus Lift technique in more than 50 lateral sinus
augmentations performed over the past four years.
Otogenic lateral sinus
thrombosis (LST) is a rare and serious intracranial complication of acute or chronic otitis media.
Some patients may develop life threatening complications like lateral sinus
thrombosis or brain abscess also.
Various complications can occur, these are meningitis, brain abscess, extradural abscess, subdural abscess, lateral sinus
thrombophlebitis and otitic hydrocephalus (4).Infection from the tympanomastoid can spread through direct bone erosion, septic embolization, normal anatomic pathways and preformed pathways.
(1-3) However, access to the lateral sinus
wall can be achieved via an endoscopic trans-sphenoid approach with excellent outcomes, as demonstrated in our case.
When paradoxically curved, the convexity is directed laterally, toward the lateral sinus
wall (Figure 3).
Presentation, treatment, and clinical course of otogenic lateral sinus
Nonseptic lateral sinus
thrombosis differs from septic lateral sinus
thrombosis in that it is not associated with ear or sinus infection.
