Overview
This book describes The Nose and Its Disorders, Diagnosis and Treatment and Related Diseases
The nose is the body’s main organ of smell and also functions as part of the body’s respiratory system. It has different shapes and sizes and is connected to the eyes and ears.
The human nose is more than a protrusion of flesh and cartilage on the front of the face.
Besides being a component of the respiratory system that inhales oxygen and exhales carbon dioxide, the nose also assists in other important functions, such as hearing and tasting.
The 2 openings in the nose are termed nostrils, or napes.
They direct to two nasal cavities that are separated by the septum, a wall of cartilage.
Inside the face is a complex system of nasal canals and pockets of air termed sinus cavities.
Projecting out of the lateral walls of the nasal cavity are 3 shelves termed nasal turbinates.
Sinus cavities pass all the way to the back of the skull, right above the oral cavity, within the cheekbones and between the eyes and brows.
The nasal passageways on either side of the nose pass into the choana (posterior nasal passageway) and then into a chamber called the nasopharynx, which is the upper part of the throat.
This chamber passes into the oropharynx, the throat area behind the mouth.
When air is breathed in the nostrils, it travels through the nasal passages, the choana, the nasopharynx, the oropharynx and the voice box and lands inside the lungs.
Fundamentally, in the respiratory system, the nose is a passageway for air to enter the lungs.
Sinus cavities spread all the way to the back of the skull right above the oral cavity, within the cheekbones and between the eyes and brows.
All of these sinus cavities are accountable, at least in part, for breathing, smelling, tasting and immune system defense.
The human nose is able to smell over 1 trillion scents.
The nose smells with the olfactory cleft which comprises the roof of the nasal cavity.
It is right next to the smelling part of the brain, which comprises the olfactory bulb and fossa.
Human noses can have a wide assortment of shapes and sizes due to genetics and injuries.
The shape of the nose differs widely caused by differences in the nasal bone shapes and formation of the bridge of the nose.
Men normally have larger noses than women.
Some deformities of the nose are present, such as the pug nose and the saddle nose.
The pug nose is featured by excess tissue from the apex that is out of proportion to the rest of the nose.
A low and poorly developed nasal bridge may also be present.
A saddle nose deformity affecting the collapse of the bridge of the nose is mostly linked with injury to the nose but can be produced by other disorders such as leprosy.
Werner syndrome, a disorder that manifests the appearance of premature aging, produces a "bird-like" appearance due to pinching of the nose.
Down syndrome often manifests a small nose with a flattened nasal bridge.
This can be caused by the absence of one or both nasal bones, shortened nasal bones, or nasal bones that have not fused in the midline
Function
1. Respiration
Air goes in the upper respiratory tract through the nose.
2. Sense of smell
The nose has olfactory receptor neurons accountable for the sense of smell.
3. Speech
Speech is caused through pressure from the lungs and altered using airflow through the nose
4. The nose plays a part in hearing through the Eustachian tube.
5. Smell from the nose help the body to taste the food properly.
6. Defense against illness
The nasal mucosa is lined with fine hairs (cilia) that filter foreign bodies.

About the Author
Medical doctor since 1972.
Started Kee Clinic in 1974 at 15 Holland Dr #03-102, relocated to 36 Holland Dr #01-10 in 2009.
Did my M.Sc (Health Management ) in 1991 and Ph.D (Healthcare Administration) in 1993.
Dr Kenneth Kee is still working as a family doctor at the age of 70.
However he has reduced his consultation hours to 3 hours in the morning and 2 hours in
the afternoon.
He first started writing free blogs on medical disorders seen in the clinic in 2007 on http://kennethkee.blogspot.com.
His purpose in writing these simple guides was for the health education of his patients which is also his dissertation for his Ph.D (Healthcare Administration). He then wrote an autobiography account of his journey as a medical student to family doctor on his other blog http://afamilydoctorstale.blogspot.com
This autobiography account “A Family Doctor’s Tale” was combined with his early “A Simple Guide to Medical Disorders” into a new Wordpress Blog “A Family Doctor’s Tale” on http://ken-med.com.
From which many free articles from the blog was taken and put together into 1000 eBooks.
He apologized for typos and spelling mistakes in his earlier books.
He will endeavor to improve the writing in futures.
Some people have complained that the simple guides are too simple.
For their information they are made simple in order to educate the patients.
The later books go into more details of medical disorders.
He has published 1000 eBooks on various subjects on health, 1 autobiography of his medical journey, another on the autobiography of a Cancer survivor, 2 children stories and one how to study for his nephew and grand-daughter.
The purpose of these simple guides is to educate patient on health disorders and not meant as textbooks.
He does not do any night duty since 2000 ever since Dr Tan had his second stroke.
His clinic is now relocated to the Buona Vista Community Centre.
The 2 units of his original clinic are being demolished to make way for a new Shopping Mall.
He is now doing some blogging and internet surfing (bulletin boards since the 1980's) starting
with the Apple computer and going to PC.
The entire PC is upgraded by himself from XT to the present Pentium duo core.
The present Intel i7 CPU is out of reach at the moment because the CPU is still expensive.
He is also into DIY changing his own toilet cistern and other electric appliance.
His hunger for knowledge has not abated and he is a lifelong learner.
The children have all grown up and there are 2 grandchildren who are even more technically advanced than the grandfather where mobile phones are concerned.
This book is taken from some of the many articles in his blog (now with 740 posts) A Family Doctor’s Tale.
Dr Kee is the author of:
"A Family Doctor's Tale"
"Life Lessons Learned From The Study And Practice Of Medicine"
"Case Notes From A Family Doctor"
