The straight sinus will receive its major drainage from thegreat cerebral veinof Galen, which passes caudally under the splenium of the corpus callosum to join it.9The great cerebral vein of Galen joins the straight sinus at the anterior tentorial edge of the straight sinus at the level of ...
What is the sinus drainage? The overflow of the mucus created in the sinus cavities happens whenever there is the excessive amount of it in them. That is, certain amount of the transparent mucus is always present over the membranes of the upper respiratory system and serves as the protection ...
More extensive surgery involves removal of the thickened membranous lining of the sinus or obliteration of the sinus itself in order to prevent refilling with purulent drainage.Since sinusitis can lead to more serious infections in nearby tissues, such as the bones of the ear and mastoid or the...
transverse sinus of pericardium a passage within the pericardial sac, behind the aorta and pulmonary trunk and in front of the left atrium and superior vena cava. tympanic sinus a deep recess on the medial wall of the middle ear. urogenital sinus an elongated sac that is formed by division ...
The air sinuses, four on each side, are cavities in thebonesthat adjoin the nose. They are outgrowths from the nasal cavity and retain their communications with it by means of drainage openings, orostia. Consequently, their lining ismucous membranesimilar to that found in the nose. Themucus...

The treatment of chronic forms of sinus infection requires longer courses of medications, such as amoxicillin-clavulanate (Augmentin), and may require a sinus drainage procedure. This drainage typically requires a surgical operation to open the blocked sinus under general anesthesia. ...
blood within them can flow in either direction. The superior sagittal sinus drains into thetransverse sinus. The transverse sinuses also receive venous drainage from small veins from both the middle ear and the mastoid cells. The transverse sinus becomes thesigmoid sinusbefore draining into theinterna...
