Chap. VI.] NOSE AND NASAL CAWTIES. 85 



The integument of the nose is very well supplied 

 with blood, and for this reason the part is well suited 

 for the many plastic operations that are performed 

 upon it. Wounds in this region heal kindly, and even 

 the extensive wound made along the line between the 

 nose and the cheek in removal of the upper jaw leaves 

 very little deformity. In many reported cases portions 

 of the nose have been entirely severed, and have 

 united to the face on being immediately re-applied. 

 In spite of its full blood supply, the nose, for reasons 

 already given when speaking of the pinna (page 73), 

 is prone to gangrene from exposure to severe cold. 

 A specimen in the museum of the Royal College of 

 Surgeons illustrates a remarkable form of gangrene of 

 the nose. The specimen is the larynx of a man who 

 cut his throat, and lost a great quantity of blood. 

 Before he died his nose sloughed. 



The skin over the root of the nose is supplied by 

 the nasal branch of the first division of the fifth ; as 

 is also the skin over the alee and in the region of the 

 nostril. The middle or greater part of the side of the 

 nose is supplied by the second division of the fifth, and 

 is the seat of pain in neuralgia of that trunk. The 

 fact that the nasal nerve is a branch of the ophthalmic 

 trunk, and has intimate connections with the eye, 

 serves to explain the lachrymatioii that often follows 

 painful affections about the nostril, as, for example, 

 when the edge of the nostril is pinched (page 57). 



The cartilaginous part of the nose is often 

 destroyed by lupus, by syphilitic ulceration, and other 

 destructive affections. The parts so lost have been 

 replaced by the various methods included under the 

 head of rhinoplasty. It is well to bear in mind 

 the limits of the cartilaginous segment of the nose, and 

 to remember that in introducing a dilating speculum 

 the instrument should not be passed beyond those 

 limits. In the subjects of inherited syphilis the bridge
