Endoscopic surgery in the treatment of crista galli pneumatization evolving with localizated frontal headaches
INTRODUCTION The crista galli is part of the ethmoid bone and thus may suffer from the process of pneumatization. Pneumatization occurs in between 3% and 14% of patients, resulting from air cells in the frontal or ethmoid sinuses. AIM To describe 3 cases of crista galli pneumatization in which the patients developed infection and were treated surgically by endoscopic techniques. METHOD W...
متن کاملCrista galli pneumatization is an extension of the adjacent frontal sinuses.
BACKGROUND AND PURPOSE The crista galli is part of the ethmoid bone and, as such, it could be expected that aeration of the crista would come from ethmoid cells. After observing crista pneumatization from the frontal sinuses in several cases, we undertook this study to establish how often crista galli pneumatization came from the frontal sinuses rather than from the ethmoid complex. MATERIALS...
متن کاملBiosynthesis of Erythrina alkaloids in Erythrina crista-galli.
A precursor application system was developed to allow the study of Erythrina alkaloid formation in Erythrina crista-galli. Fruit wall tissue of this species was recognized as the major site of alkaloid biosynthesis. The application of radioactively and 13C-labelled potential precursors showed that the hitherto assumed precursor (S)-norprotosinomenine was not incorporated into the Erythrina alka...
متن کاملBilateral frontal cysts from a crista galli meningioma.
A 73-year-old woman had progressive apathy, forgetfulness, and gait disturbance for 6 months. Neurologic examination showed inattentiveness, memory impairment, and broad-based gait. Noncontrast MRI was performed due to gadolinium allergy. MRI and contrast-enhanced CT scan revealed symmetric bilateral frontal cysts (figure 1A) and an anterior skull base nodule (figure 1, B and C). Surgery confir...
