Endoscopic marsupialization of frontoethmoid mucocele with underlying craniofacial fibrous dysplasia.

Fibrous dysplasia (FD) is a benign progressive fibro-osseous lesion that is rarely associated with mucocele formation. This complication most probably results from the involvement and subsequent occlusion of the recesses of the sinuses by the dysplastic process. The frontoethmoid mucocele associated with FD represents a rare pathology, but it is important to consider this in the differential diagnosis of patients with proptosis, visual disturbance, and bony fronto-orbital swellings.

Radiologic analysis of high jugular bulb by computed tomography.

Introduction: Many previous studies of high jugular bulb (HJB) have limitations, such as focusing simply on the incidence or having a relatively small number of subjects. The objective of this article was to investigate the overall incidence of HJB and bony dehiscence in HJB on a large scale using high-resolution temporal bone computed tomography. The other purpose was to measure the horizontal distance from the tympanic annulus and the height above the annulus.
