Then the ethmoid bone was broken and decomposed, softened brain was teased through the nostril by using a metal hook. |

Objective: The ethmoid bone is arguably the most complex and varied osseous structure in the human body. |
|
Olfactory nerve fibers enter the cranial cavity through foramina in the cribriform plate of the ethmoid bone and synapse on neurons in the olfactory bulb. |
|
The instrument would have been inserted through a hole punched into the ethmoid bone near the nose. |
|
Therefore, nasal fibroscopic examination represents the best tool to detect adenocarcinoma of the ethmoid sinuses at its earlier stages. |
|
Mucocoeles of the ethmoid and frontal sinuses commonly present with symptoms and signs caused by displacement of adjacent structures caused by a process of slow expansion. |
|
Based on experts' opinions, they have never been assessed as effective in the detection of adenocarcinoma of the ethmoid sinus. |
|
|
Near the front of the brain, in the midline, a deep sagittal groove in the dura indicates the site where the crista galli of the ethmoid bone is accommodated. |
|
The surgical anatomy of the ethmoid bone, and the ethmoidal bulla in particular, is ill-defined and heretofore largely unclassified. |
|
The skull includes the frontal, sphenoid, ethmoid, occipital, parietal and temporal bones. |
|
Their conversation became studded with lovingly enunciated medical reference: tachycardia, ileitis, the ethmoid sinuses. |
|
Sinus CT was then obtained and revealed soft tissue density opacification of the maxillary, ethmoid, sphenoid, and frontal sinuses. |
|
Entellus Medical's treatment is designed to enlarge the maxillary sinus ostium and ethmoid infundibulum. |
|
The interior surface of the left fr contains a fragment of the lateral ethmoid and sphenotic. |
|
Spontaneous CSF fistulae are most common in the anterior cranial fossa, at the ethmoid roof and cribriform plate. |
|
He underwent uvulopalatopharyngoplasty and tonsillectomy and a nasal surgery with ethmoid polyp resection. |
|
In the second type, described by the same authors, the PPO ℓA rose from the ACA and passed through the cribriform plate of the ethmoid bone to supply the nasal cavity, similar to the ethmoidal arteries. |
|
On posteroanterior cephalometric radiographs taken at the initial examination, the midline was defined as the line that passed through the crista galli of the ethmoid bone, perpendicular to the Lo-Lo′ line. |
|
Lateral ethmoid with cartilaginous condyle for articulation with lacrimal, supported dorsally and ventrally by osseous laminae. |
|
Skeletal elements of the chondrocranium were simplistic and dominated by the hyoid, hyomandibulosymplectic cartilage, ethmoid and Meckel's cartilage in first feeding larvae. |
|
A follow-up MRI scan in 2009 showed contrast-enhancing soft tissue abnormalities within both of the frontal sinuses and the left ethmoid sinus. |
|
Examination of the right and left ethmoid sinus specimens revealed mild chronic inflammation with rare eosinophils. |
|
Results: Wood dust less than 10 µm settles on the external aspects of the ethmoid sinus that is the middle turbinate, the middle meatus and the olfactory cleft. |
|
According to Prof. John Percy Moore, of the Univ. of Peen., who is one of the worlds outstanding authority on leeches, this creature occasionall slips into the nasal passage and lodges in one of the ethmoid sinuses. |
|
Patients and methods: A case of respiratory epithelial adenomatoid hamartoma of the ethmoid sinus and a review of literature are reported in order to describe the diagnostic and therapeutic management of this tumour. |
|
The frontal sinuses are most frequently affected, followed by the ethmoid, maxillary and sphenoid. |
|
The maxillary sinus is the first paranasal sinus to develop from the ethmoid sinuses. |
|
|
The nasal polyp and sinusitis tissues were obtained from the ethmoid sinus in the 64 patients. |
|
Surgeons used a headlight, grasping or biting forceps, and ethmoid curettes. |
|
The Propel system has been clinically proven to prevent obstruction of the ethmoid sinus following surgery. |
|
Three tumors involved frontal and ethmoid sinuses concomitantly making it impossible to determine a single site of origin. |
|
Such lateral developments of the ethmoid plate are the aliethmoid, aliseptal, and alinasal. |
|
A cell that pneumatises into the frontal bone is named a frontal cell of the anterior ethmoid or bulla frontalis, and lies above the ethmoid bulla. |
|
Computed tomography of the sinuses detected bilateral conchae bullosa of the middle turbinates with mucosal thickening in the middle meatus and ethmoid infundibula. |
|
A circumstance in which the ostia of the ethmoid bulla connect through the basal lamella into the posterior ethmoid labyrinth is an unusual finding. |
|
An unusual finding on the CT scan was what appeared to be an ostium or drainage pathway from the left ethmoid sinus into the superior portion of the left middle meatus. |
|
It wasn't designed to remove polyps or treat ethmoid sinus disease. |
|
The basal lamella of the ethmoid, the ethmoid strut, the anterior and posterior ethmoid cells, the medial wall of the ethmoid sinus, and the agger nasi cell were all removed. |
|
No bleeding was noted in the nose, and the ethmoid sinuses had not yet been dissected on that side, so an arterial bleed was discounted as the cause. |
|
Left endoscopic ethmoidectomy was carried out through the anterior face of the left ethmoid bulla using a microdebrider to open the anterior ethmoid area. |
|
The cleithrum, 17th most abundant, is underrepresented in comparison with many cranial bones, but outnumbers others such as the sphenotic, ethmoid, otolith and preopercular. |
|
These defects can now easily be accessed via endoscopic transnasal techniques, especially the cribriform plate, the roof of the ethmoid sinuses and the sphenoid sinus. |
|
Frontal sinus was the most common primary site, followed by ethmoid sinus. |
|
Computed tomography of the sinuses showed evidence of the ethmoidectomy and a right middle meatal antrostomy in addition to left ethmoid opacification. |
