Background: Removal of the surrounding bone during dacryocystorhinostomy may present a higher risk of skull base injury in patients with frontal sinus aplasia. We used sinus plain films to predict cases with a greater risk of a reduced skull base dis...
1 March 2009
Frontal sinus fracture represents 5 to 12% of all maxillofacial fractures. Because of the anatomic position of the frontal sinus and the enormous amount of force required to create a fracture in this area, these injuries are often devastating and ass...

An unusual pervasive and persistent asymmetry in background rhythm was found on surface electroencephalography (EEG) recordings in a 22 year old with new onset of generalized seizure activity. Radiographic correlation with computed tomography, positr...
Pressures applied to horses via nosebands are of growing concern. The current study applied noseband pressure to the head of a dead horse. Pressure sensors were placed on the left nasal bone to record pressures as the noseband was progressively tight...
Surgery in patients with craniosynostosis is a common treatment to correct the deformed skull shape, and it is necessary to verify the surgical effect of correction on the regional cranial bone. We propose a quantification method for evaluating surgi...
Background: The endoscopic modified Lothrop procedure (EMLP) is a common procedure performed in patients with frontal sinus pathology. While performing this procedure, large segments of bone are exposed, which may lead to the promotion of frontal sin...
