INSHIRAH QADRI
Nose, Mouth, and Throat
1
NOSE
1ST segment of the respiratory system
Sensory organ for smell
Olfactory :S / test sense of smell
2
Nasal Cavity
Nasal cavity-much larger than external nose
-Extends back over the roof of the mouth
Nasal hair filter inhaled air
Rest of cavity lined with ciliated mucous
membrane to filter out dust and bacteria
Nasal cavity divided medially by the
septum into 2 air passages
Anterior part of septum holds rich
vascular network(Kiesselbach’s plexus)
3
Nasal Cavity
Nasal mucosa appear more red
in color than oral mucosa
3 parallel bony projections
Superior turbinates
Middle turbinates
Inferior turbinates
Underlying each turbinate is the
meatus
The sinuses drain into the middle meatus
Tears drain into the inferior meatus
4
Structures of the Nasal Cavity
5
Paranasal Sinuses
Air-filled pockets within the cranium
lined with ciliated mucous membrane
Functions: lighten wt. of skull bones, serve as resonators
for sound production, and provide mucus, which drains into
nasal cavity
Sinus openings
narrow & easily occluded
6
Nose - Sinuses
Frontal and
maxillary
Which sinuses can
we examine?
Only the ethmoid and
maxillary sinuses are
present at birth. Frontal
develop between 7 and 8
years. Sphenoid develop
after puberty.
7
Mouth
Segment of the digestion & respiratory systems
Oral cavity- contains teeth, gums, tongue, and salivary glands
Hard palate-anterior: bone and is white
Soft palate-posterior: muscle , pink & mobile
8
Mouth
Uvula-free projection hanging down from the middle of the soft
palate
Floor of mouth-consists of mandible bone, the tongue, and
underlying muscles
Tongue- striated muscle; papillae on its dorsal surface
Frenulum- midline fold of tissue that connects the tongue to the
floor of the mouth

Oral Cavity Structures
10
Salivary Glands
Parotid Gland
Largest
Lies within the cheeks in front of the ear
Submandibular
size of a walnut
Lies beneath the mandible
Sublingual
Smallest
Almond-shaped
lies under the tongue
11
Salivary Glands
12
Teeth
Adults have 32 permanent teeth-
16 upper arch & 16 lower arch
Tooth-crown, neck & root
Gums (gingivae) -thick fibrous
tissue covered with mucous
membrane
13
•There are 32 adult teeth, 16 in each jaw. 14
Subjective Data
OLD CART
Nose: Epistaxis; nosebleeds
allergies, altered ell,discharge…etc
Mouth and throat:
Dysphagia-difficulty swallowing,
bleeding gum
Smoking , toothache, sore throat
Self care behaviors
15
Inspect and Palpate the Nose
External nose
symmetric, in the midline, and in proportion to other facial
features
Nasal cavity
red color, smooth and moist surface
Nasal septum
no deviation, no bleeding or perforation
Middle and inferior turbinates
light red color
no polyps-smooth, pale gray, and non-tender
16
The Nasal Cavity
➢ Speculum
No swelling, discharge or foreign body
17
Palpate the sinus areas
Using thumbs, press over frontal sinuses below eyebrow, and over maxillary sinuses below cheekbone.
18
Inspect the Mouth
Lips: Pink color, moist, no cracking, or lesions
Oral mucosa: color, ulcers, white patches
Teeth absent, loose, or abnormally positioned
teeth
Gums pink or coral with dotted
surface
19
Tongue
Dorsal surface pink and even with
a thin white coating
rough
Ventral surface-smooth, glistening, and shows veins and saliva
No white patches or lesions
❖Palpate the tongue under
❖ the tongue( U shape)
No lesions, nodules, ulcerations.
20
Tongue
Assess the hypoglossal nerve(CN XII).
Motor assessment
Ask the client to roll the tongue upward.
Ask the client to move from side to side and protrude out.
ask the patient to push the tongue against the inside of each cheek in turn as you palpate externally for strength.
Ask the client to say "Light tight Dynamite". Note lingual speech. (Sound of letters I, t, d, & n) is clear
& distinct.
Seosory assessment
Assess the tongue for taste (CN Vll and CN lX).
21
Inspect Palate
Shine light up to the roof
of the mouth
anterior hard palate-white
posterior soft palate-pink,
smooth and upwardly mobile
uvula-ask person to say ahh - the
soft palate and uvula rise in the
midline (CN IX & X)
22
Inspect the Throat
Using light, observe the oval, rough-surfaced tonsils; color
pink with indentations
Depress tongue with tongue blade to view the posterior
pharyngeal wall
No enlargement, no bad odor and good hygiene
+1: tonsils are visible
+2: tonsils are between the
tonsillar pillars & the uvula
+3: tonsils are touching the uvula
+4: tonsils are touching each other.
