Ethmoidectomy
Ethmoidectomy is the medical name for a procedure that involves removing the partitions between the ethmoid sinuses in order to create larger sinus cavities. This procedure treats sinus infection Sinusitis, also known as rhinosinusitis, is an inflammation of the mucous membranes that line the sinuses resulting in symptoms that may include production of thick nasal mucus, nasal congestion, facial congestion, facial pain, facial pressure, ...s and sinus obstructions that have been the cause of chronic sinus problems. The procedure may also involve the removal of nasal polyps present in the ethmoids. References Rhinology {{Surgery-stub ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethmoid Sinus
The ethmoid sinuses or ethmoid air cells of the ethmoid bone are one of the four paired paranasal sinuses. Unlike the other three pairs of paranasal sinuses which consist of one or two large cavities, the ethmoidal sinuses entail a number of small air-filled cavities ("air cells"). The cells are located within the lateral mass (labyrinth) of each ethmoid bone and are variable in both size and number.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, page 64 The cells are grouped into anterior, middle, and posterior groups; the groups differ in their drainage modalities, though all ultimately drain into either the superior or the middle nasal meatus of the lateral wall of the nasal cavity. Structure The ethmoid air cells consist of numerous thin-walled cavities in the ethmoidal labyrinthOtorhinolaryngology, Head and Neck Surgery, Anniko, Springer, 2010, page 188 that represent invaginations of the mucous membrane of the nasal wall into the ethmoid bo ...

Sinus Cavity
Paranasal sinuses are a group of four paired air-filled spaces that surround the nasal cavity. The maxillary sinuses are located under the eyes; the frontal sinuses are above the eyes; the ethmoidal sinuses are between the eyes and the sphenoidal sinuses are behind the eyes. The sinuses are named for the facial bones and sphenoid bone in which they are located. Their role is disputed. Structure Humans possess four pairs of paranasal sinuses, divided into subgroups that are named according to the bones within which the sinuses lie. They are all innervated by branches of the trigeminal nerve (CN V). * The maxillary sinuses, the largest of the paranasal sinuses, are under the eyes, in the maxillary bones (open in the back of the semilunar hiatus of the nose). They are innervated by the maxillary nerve (CN V2). * The frontal sinuses, superior to the eyes, in the frontal bone, which forms the hard part of the forehead. They are innervated by the ophthalmic nerve (CN V1). * The eth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinus Infection
Sinusitis, also known as rhinosinusitis, is an inflammation of the mucous membranes that line the sinuses resulting in symptoms that may include production of thick nasal mucus, nasal congestion, facial congestion, facial pain, facial pressure, loss of smell, or fever. Sinusitis is a condition that affects both children and adults. It is caused by a combination of environmental and a person's individual health factors. It can occur in individuals with allergies, exposure to environmental irritants, structural abnormalities of the nasal cavity and sinuses and poor immune function. Most cases are caused by a viral infection. Recurrent episodes are more likely in persons with asthma, cystic fibrosis, and immunodeficiency. The diagnosis of sinusitis is based on the symptoms and their duration along with signs of disease identified by endoscopic and/or radiologic criteria. Sinusitis is classified into acute sinusitis, subacute sinusitis and chronic sinusitis. In acute sinusitis, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nasal Polyps
Nasal is an adjective referring to the nose, part of human or animal anatomy. It may also be shorthand for the following uses in combination: * With reference to the human nose: ** Nasal administration, a method of pharmaceutical drug delivery ** Nasal emission, the abnormal passing of oral air through a palatal cleft, or from some other type of pharyngeal inadequacy ** Nasal hair, the hair in the nose * With reference to phonetics: ** Nasalization, the production of a sound with a lowered velum, allowing some of the air to escape through the nose; the resulting being either: *** a nasal consonant, or *** a nasal vowel * With reference to the nose of humans or other animals: ** Nasal bone, two small oblong bones placed side by side at the middle and upper part of the face, and form, by their junction, "the bridge" of the nose ** Nasal cavity, a large air filled space above and behind the nose in the middle of the face ** Nasal concha, a long, narrow and curled bone shelf which pro ...
