What is intranasal ethmoidectomy?
Intranasal ethmoidectomy is a. common. otolaryngological procedure performed for the. treatment of chronic ethmoiditis with or with- out.
What is opacification of the sinuses?
Sinonasal inflammatory disease with sinus ostial obstruction is a very common cause of an opacified paranasal sinus. An air-fluid level suggests acute sinusitis; in chronic sinus disease, one may see mucosal thickening and sclerosis of the bony sinus walls. 1. The sinus is normal in size.
What causes opacification?
The opacification is caused by fluid or solid material within the airways that causes a difference in the relative attenuation of the lung: transudate, e.g. pulmonary edema secondary to heart failure. pus, e.g. bacterial pneumonia. blood, e.g. pulmonary hemorrhage.
How do I unblock my ethmoid sinus?
3. Sphenoid/ethmoid sinus massage
- Place your index fingers on the bridge of your nose.
- Find the area between your nasal bone and the corner of the eyes.
- Hold a firm pressure in that spot with your fingers for about 15 seconds.
- Then, using your index fingers, stroke downward along the side of the bridge of your nose.
What is the function of the lamina cribrosa?
Anatomically, the lamina cribrosa, which is located in the posterior sclera, helps to preserve a pressure gradient between the extraocular and intraocular spaces [12]. It is within the passage of the lamina cribrosa that RGC axons are thought to be most vulnerable to IOP-related stress and strain [13].
Is lamina cribrosa imaging a useful biomarker of glaucoma-related RGC injury?
Lamina cribrosa imaging also has the potential to improve understanding of mechanisms of glaucomatous RGC injury, and although the temporal relationship between lamina cribrosa and neural changes remains uncertain, there is the possibility that lamina cribrosa changes may be a useful biomarker of increased risk of neural losses.
What is the relationship between lamina cribrosa defects and neuroretinal rim thinning?
Figure 4illustrates the right eye of a glaucoma patient with localized RNFL defect and a focal defect in the lamina cribrosa. A cross-sectional study investigated the association between focal lamina cribrosa defects and neuroretinal rim thinning/notching and acquired pits of the optic nerve [53].
What is enhanced depth imaging of lamina cribrosa?
Enhanced depth imaging detects lamina cribrosa thickness differences in normal tension glaucoma and primary open-angle glaucoma. Ophthalmology. 2012;119:10–20. [PubMed] [Google Scholar] 51. Park HY, Shin HY, Park CK.
