SUEGICAL ANATOMY OF THE REGION OF THE 

 NOSE. 



The structure of the skin of the nose is very similar to 

 that in other parts of the body, except that it is very 

 thin and loosely connected with the subjacent parts. The 

 hairs are but rudimentary, and the sebaceous glands very 

 numerous and largely developed. These orifices show 

 themselves as points more or less deep, most abundant 

 on the alse. Underneath is a layer of cellular tissue very 

 adherent to the skin and subjacent musculo-fi brous tissues 

 containing a little fat. 



The muscles of the nose belong to those of expression, 

 and are as follows : pyramidalis nasi, levator labii stiper- 

 ioris et alse nasi, dilator naris, compressor nasi, compressor 

 narium minor, depressor alse nasi. 



The arteries of the nose are derived from the ophthal- 

 mic and the facial, the sides and dorsum being supplied 

 by the nasal branch of the ophthalmic and the infra- 

 orbital, the alse and septum by the superior coronary, 

 and by the lateralis nasi. 



The veins terminate in the facial and ophthalmic. 



The nerves are derived from the facial, infra-orbital, 

 infra-trochlear, and a twig from the nasal branch of the 

 ophthalmic of the fifth. 



There are numerous lymphatics, which empty them- 

 selves into the submaxillary glands (lymphatic), and fol 

 low the course of the facial vein.
