introduction frontal sinus mucoceles are the commonest among all paranasal mucoceles. with introduction of functional endoscopic sinus surgery, surgeons prefer endoscopic management of sinus mucoceles, but lesions that appear in the lateral part of the frontal sinus can be difficult to access and often need external approaches. case presentation we described a lateral frontal sinus mucocele wit...

Automatic head frontal-view identification is challenging due to appearance variations caused by pose changes, especially without any training samples. In this paper, we present an unsupervised algorithm for identifying frontal view among multiple facial images under various yaw poses (derived from the same person). Our approach is based on Locally Linear Embedding (LLE), with the assumption th...

OBJECTIVES/HYPOTHESIS To validate the endonasal surgical approach to frontal sinus in inflammatory sinus disease, trauma, and selective tumor surgery, and to define the role of external approaches to the frontal sinus. Endonasal frontal sinusotomy can range from endoscopic removal of obstructing frontal recess cells or uncinate process to the more complex unilateral or bilateral removal of the ...

We present the case of a 64-year-old woman who came to Emergency Services with a left frontal mass that was painful when palpated. The mass had a history of 3 days, lacking affectation of ocular motility and nasal symptoms. With the diagnostic suspicion of frontal mucocele, she was admitted to begin antibiotic treatment. In the CT performed, the image showed mainly left frontal occupation with ...

introduction: the surgical management of chronic frontal sinus disorders remains a challenge for rhinologists. the aim of this study was to evaluate the result of draf iii in a series of patients who underwent this procedure.   materials and methods: twenty patients were included in this study. demographic data, history of prior surgery, asthma,  aspirin sensitivity and lund–mackay score were r...

background morphometric data of the frontal lobe are important for surgical planning of lesions in the frontal lobe and its surroundings. magnetic resonance imaging (mri) techniques provide suitable data for this purpose. objectives in our study, the morphometric data of mid-sagittal mri of the frontal lobe in certain age and gender groups of children have been presented. patients and methods i...
