The lateral wall of the nasal cavity formed by the ethmoid bone contains rounded shelf-like projections termed as “turbinates.” The turbinates are named “superior,”“middle.” and “inferior” based on their location in craniocaudal location and overlie their respective meatuses. If there ...
The significance of agenesis of the ethmoid bone in the development of normal and holoprosencephalic facial features has not been considered previously. On the basis of several morphological variations in the two specimens described, it is evident that the ethmoid bone provides integral support in ...
What are the four parts of the upper extremity and the lower extremity of the appendicular skeleton? The greater trochanter and lesser trochanter are features of what bone? Which is the longest bone in the body and its characteristics? What are two structures or anatomical features that ...

A 46-year-old man complained of a 1-month history of left-sided nasal obstruction. Computed tomography scan and magnetic resonance imaging showed a tumor mass involving the left nasal cavity, ethmoid sinus, and ethmoid bone with extension to the left frontal lobe of the brain. A gross total...
The cranial bones that make the sutures are usually of intramembranous origin. An exception to this generalization, the frontoethmoidal suture, is formed at the junction between an intramembranous bone and an endochondral bone. This chapter gives information about the bones forming the skull and the...
Tumour location and extent, MRI signal intensities, noncontrast CT attenuation, patterns of enhancement, and changes in adjacent structures were evaluated. Results All four tumours involved the sphenoid bone. In three patients, the tumour extended to the ethmoid sinus and both cavernous sinuses. All...
the pterygoid process, medial bony wall, and ethmoid sinus had a tendency to be spared in most of the 5 patients with second maxillary cancer compared to the 21 control cases.Key Words: Jaws, CT,聽maxillary sinus, neoplasmsHitoshi Shibuya...
In all patients, the ethmoidal infundibulum was obstructed by prolapsed orbital fat with secondary antral consolidation, and inward bowing of the maxillary walls was present in five of six patients. After antral drainage and packing, there was an improvement in enophthalmos (mean, 2.7 mm; range...
