Talk:Paranasal sinuses

message: more details of structure please.  they are just empty pockets of air?  how does the air get there?  are they lined with tissue or Moo Hog are they just bone?  hoopenings does each have?  how do they becom e "pressurized"? etc etc- User:Omegatron
* The question above was posted in May 2005 and still has not been answered. Could someone please do so:
**HOW DOES THE AIR GET IN THERE??
**and, once in there - does it have constant contact with the outside air, or is it a one-off deal and then sealed forever?
**and is it actual atmospheric air - 78% nitrogen, 20% oxygen, etc, including all the impurities and pollution, or does it somehow get filtered and stay filtered? if so, how?
**also - what are the insides of the sinuses lined with - some special body fluid, or some skin-like tissue, or just dry bone? it has to be something - otherwise where woiuld the pus come from in sinusitis? is there a capillary blood supply to the lining of each, etc, or just some inorganic veneer like tooth enamel?
**and what is the volume of each sinus? and are they all somehow joined to each other, or is each one a completely separate entity?
* ALL these points are quite relevant to the article, so could someone in the know PLEASE answer them. Thanx BigSteve (talk) 14:14, 20 September 2008 (UTC)

message: From a zoological persective, this sort of expression is viewed as a bit Victorian. It is certainly not very helpful especially when a number of functions are listed directly above. Tonsils and adenoids used to be viewed as vestiges before it was realised that they are a useful part of the lymphoid system.
Can I suggest that the phrasing is changed? Jellytussle 19:40, 19 January 2006 (UTC)
thread_title:  Vestigial anachronisms? 

message: The Journal of Modern Vision Science doesn't appear to be a well-established journal.  It is has no articles indexed by PubMed, its website shows no editors well-established in the field.  Either it is a very new organisation or its a garden shed project.  Whichever it is, I'd be wary of claiming that sinuses play "a role in moderating the influence of the respiratory system on the visual system" unless it is backed up with some more concrete evidence. - Pgr94 13:22, 29 March 2006 (UTC)

thread_title:  Bogus role of sinuses? 

message: As the article is currently written, one would assume that paranasal sinuses are restricted just to humans. However, they occur across a number of animals. I would suggest restructuring the article to reflect this.Diceratops 15:11, 5 December 2006 (UTC)
thread_title:  Must generalize this article 

message: Does anyone know if there has ever been a documented case of an adult with one or more missing sinus cavities (particularly the frontal cavities)? Is there a medical condition in which one or more sinus cavities are absent or extremely small?
Thanks

message: I'm copying this extract here - for discussion - and perhaps this information should then be incorporated in this article.  Seems a rather significant function for the paranasal sinuses,  wouldn't you think?

Nitric Oxide and the Paranasal Sinuses.
Lundberg JO.

The discovery within the paranasal sinuses for the production of
nitric oxide (NO) has altered the traditional explanations of sinus
physiology. This review article reports the ongoing investigation of
sinus physiology beginning with the discovery of NO gas production in
the paranasal sinuses that occurred in 1995, and the impact that
finding has had both in the basic science and clinical arenas. It was
shown that healthy paranasal sinus epithelium expresses an inducible
NO synthase that continuously generates large amounts of NO, a
pluripotent gaseous messenger with potent vasodilating, and
antimicrobial activity. This NO can be measured noninvasively in
nasally exhaled breath. The role of NO in the sinuses is likely to
enhance local host defense mechanisms via direct inhibition of
pathogen growth and stimulation of mucociliary activity. The NO
concentration in a healthy sinus exceeds those that are needed for
antibacterial effects in vitro. In patients with primary ciliary
dyskinesia (PCD) and in cystic fibrosis, nasal NO is extremely low.
This defect NO generation likely contributes to the great
susceptibility to chronic sinusitis in these patients. In addition,
the low-nasal NO is of diagnostic value especially in PCD, where nasal
NO is very low or absent. Intriguingly, NO gas from the nose and
sinuses is inhaled with every breath and reaches the lungs in a more
diluted form to enhance pulmonary oxygen uptake via local
vasodilation. In this sense NO may be regarded as an "aerocrine"
hormone that is produced in the nose and sinuses and transported to a
distal site of action with every inhalation. Anat Rec, 291:1479-1484,

message: So what's the function of these things?  I came here just to figure that out and it doesn't even say.  You would think that would be in the first paragraph.  — Preceding unsigned comment added by 192.145.243.154 (talk) 15:38, 30 June 2018 (UTC)
