Nose, Mouth & Throat N1037

Nose A & P Review structure and function of External nose, nasal fossa, internal nose (p 377)

Nose A & P

Nasal Cavity Extends over the roof of the mouth Lined with coarse nasal hairs Mucous blanket filters out dust and bacteria Divided by the septum 3 parallel bony projections: superior, middle and inferior turbinates. Olfactory receptors lie at the roof of the nasal cavity

Nose – Sinuses 4 pairs of Sinuses: air-filled within the cranium, serve as resonators for sound production, lighten the weight of skull bone, provide mucous and drain into the nasal cavity. Ethmoid: between the orbits (smaller and deeper) Sphenoid: deep within the skull in the sphenoid bone (post. to nasal cavity). These are non-palpable

Nose - Sinuses These are Palpable Frontal: in frontal bone, above and medial to the orbits. Maxillary: in the maxilla (cheekbone) along the side walls of the nasal cavity.

Structure and Function Exterior and Interior Mouth Structure and Function Exterior and Interior

Exterior structures

Head-Salivary Glands 3 pairs of Salivary glands: parotid, submandibular and sublingual Parotid: ant. and below the ear in cheeks, normally not palpable, secret amylase-rich fluid through Stensen’s Ducts located near upper 2nd molars Submandibular: beneath the mandible, size of walnuts, opens at either side of the tongue frenulum Sublingual: lie in the floor of the mouth, has many small openings along the sublingual fold under the tongue.*

Structure and Function Throat Structure and Function

Throat (Pharynx) Area behind the mouth and the nose Oropharynx Tonsils: mass of lymphoid tissue, deep crypts Nasopharynx: above and continuous with oropharynx, behind the nasal cavity Pharyngeal tonsils (adenoids) and eustachian tube openings here

Objective Data Inspection and Palpation Nose, Mouth & Throat Objective Data Inspection and Palpation

Assessment of Nose External Inspection Symmetric Midline Proportionate to other facial features Deformity, asymmetry Inflammation Skin lesions

Assessment of Nose Inspect and palpate external nose Patency Inspect external nose for symmetry Palpate external nose noting any tenderness - may indicate inflammation Patency Occlude one nostril at a time with a finger and ask pt to breath in & out through the nose. Internal Inspection Extend pt’s head, place non dominant hand on pts head and use thumb to lift the tip of the nose , insert nasal speculum or otoscope and inspect nasal septum, turbinates

Nasal Cavity – Inspection (short, wide tipped speculum to otoscope) N- nasal mucosa should be pink or dull red colour, smooth, moist surface with small amount of clear watery discharge. Nasal septum: *deviations, perforations or bleeding (airflow must not be obstructed) Note *polyps, (benign growths that sometimes accompany chronic allergy) Note swelling, *discharge (watery, copious to thick, purulent, green-yellow) Bleeding or foreign body

Assessment of Sinuses Inspection Observe patients face for any swelling around nose and eyes N= no evidence of swelling

Sinuses – Palpation Client feels pressure but no pain Press frontal sinuses (below eyebrows) Press maxillary sinuses ( below cheekbones) Chronic allergies and acute infections (sinusitus) = tenderness to sinuses

Perscussion of Sinuses Gently percuss frontal and maxillary sinuses using direct percussion technique N = elicits a resonant sound indicating air filled cavity If a dull sound is heard = fluid in cavity note any signs of tenderness or pain which may indicate sinusitis due to infection, allergies

Transillumination of the Sinuses Turn lights off in room Place strong light under bony ridge of upper orbits Observe red glow Place strong light under each eye just above the infraorbital ridge Ask pt to open mouth Observe red glow on hard palate N= glow on each side is equal indicating air filled frontal and maxillary sinuses

Mouth Inspection Breath Should smell fresh Lips Teeth, Buccal mucosa & Gums White, straight, evenly spaced, clean and free of debris or decay Note absent, loose, abnormally positioned Gums are pink with margins tight and well defined. Note swelling, retractions, spongy or bleeding gingivae. Breath Should smell fresh Lips Observe colour, moisture, swelling cracking or lesions Inner surface pinkish-red.

Mouth – Inspection Mucous membranes Pink, smooth and moist Tongue Palate – hard (anterior) and soft (posterior) Anterior: white with irregular transverse rugae Posterior: pink, smooth and movable “Say ahhh,”: soft palate and uvula rise (may be split in two) Tongue Pink and even, roughened White coating may be present Ventral suface smooth, shows veins Saliva present Note *induration on palpation

Mouth - Palpation Don gloves LIPS = Pull pts lower lip with thumb and index finger N= lips should be flaccid and without lesions Tongue = ask pt to stick out tongue (CNXII) Move tongue from side to side, and up and down Press tongue against cheek on each side Using gauze and gloves hold tongue and inspect ventral surface for Whartons’ ducts, frenulum, color, hydration, lesions, inflammation and vasculature N= tongue is midline, dorsum is pink, moist with taste buds (rough) and without lesions. Tongue strength is equal. Ventral surface has visible vasculature. Lateral aspect is pink, moist and free of lesions

Salivary and Parotid Gland Inspect and palpate Note for enlargement of salivary gland as the client moves their head back and forth Note swollen parotid gland with head extended ( below the angle of the jaw)

Throat - Inspection Ask pt to stick tongue out Place tongue depressor on middle third of tongue Shine light at back of pt throat Ask pt to say “ah” & observe uvula Observe tonsillar pillars Touch posterior third of tongue & observe for gag reflex N= soft palate, uvula is midline and rises symmetrically (CN IX & X), gag reflex is present, tonsils are not enlarged

Throat - Inspection Tonsils Tonsil - Grade pink, peppered with indentations or crypts. No exudate present Graded Tonsil - Grade 1+ visible 2+ halfway pillars/uvula 3+ touching uvula 4+ touching each other

Developmental Considerations Infant and children Drool before they swallow Milia on nose No nasal flaring present Note # of teeth 20 temporary (by 2 ½) Lost between 6 and 12 Pregnant Gingivitis Stuffiness and epistaxis Aging Adult Mouth and lips fold in Changes to appearance of teeth, gums recede Mucosa is shinier, thinner, less vascular Tongue is smoother (atrophy) Sense of smell diminishes
