Abstract
|
|
|
A retrospective analysis of 36 cases of petrous pyramid fractures was studied clinically and radiographically during last 5 years.
Of 503 patients with skull fractures admitted to the Inha University hospital, of which 7.1% involved the petrous pyramid.
The most common mode of injury was a motor vehicle accident and the most common age group was the first decade.
The anatomic location of fractures in the petrous pyramid were evaluated by high resolution computed tomography and it disclosed 20 longitudinal and 16 transverse fractures.
The principal symptoms and signs, occurring alone or in combination, were a otologic problem, facial paralysis and CSF liquorrhea. The otologic problems were noted in almost every case. The facial palsy and CSF liquorrhea were present in 16 cases
(36%)
and 9 cases (25%), respectively.
The anatomic type of fractures well corresponded to the principal symptoms and signs and the prognosis, the development rate of principal symptoms and signs of the transverse fracture was more higher and the prognosis of that was worse than the
longitudinal fracture.
