The intervening cancellous tissue is called the diplo? and this, in the nasal region of the skull, becomes absorbed so as to leave spaces filled with air the paranasal sinuses between the two tables.

This work was covered in Negus's Hunterian Lecture, delivered on 20 May 1954 at the Royal College of Surgeons under the title " Introduction to the Comparative Anatomy of the Nose and Paranasal Sinuses ".

For solids and liquids like bone, muscle and blood, this added pressure is not much of a problem; but it is a problem for any air-filled spaces like the mouth, ears, paranasal sinuses and lungs.

Pressure changes can cause a " squeeze " or barotrauma in the tissues surrounding trapped air inside the body, such as the lungs, behind the eardrum, inside paranasal sinuses, Breathing high-pressure oxygen may cause oxygen toxicity.

A fracture in conjunction with an overlying laceration that tears the epidermis and the meninges, or runs through the paranasal sinuses and the middle ear structures, bringing the outside environment into contact with the cranial cavity is called a compound fracture.

He was a member of numerous international and national otolaryngology organisations, and presided over the Fourth International Congress of Otolaryngology in London in 1949 . In this period of his career following the Second World War he also worked on the anatomy of the paranasal sinuses, and played a key role in rebuilding and establishing collections of animal dissections used by comparative anatomists.

The worst would be trying to clean your nose the usual way, i . e ., by pressuring your nose while holding a kerchief ( and possibly closing the nose opening, that's the really worst ), because this way you push the MRSA into your paranasal sinus where it will thrive and go into the other sinuses .-- talk ) 07 : 38, 3 August 2008 ( UTC)
