Study Notes

Ear Examination

Inspect the ear canal for discharge, redness, odor, nodules, or cysts.
Perform otoscopic examination to assess tympanic membrane and middle ear structures.
Normal tympanic membrane appears pearl gray, glistening, and transparent.
Look for abnormalities such as bulging, retraction, bleeding, lesions, or perforations.

Common Ear Disorders

Earache: Indicative of external or middle ear disorders; often linked to infections and can cause hearing loss or otorrhea.
Hearing Loss: May be due to cerumen impaction, foreign bodies, polyps, or otitis media, which thickens fluid in the middle ear.
Otosclerosis: Hardening of middle ear bones affecting sound transmission.
Trauma: Can disrupt the bony chain in the middle ear.

Otitis Media

Inflammation of the middle ear, stemming from eustachian tube blockage.
Can be classified as suppurative (with infection) or secretory (without infection) and can be acute or chronic.
Acute Otitis Media: Characterized by rapid onset, infected fluid, and short duration.
Symptoms: Ear pain, especially when lying down, tugging at an ear, trouble sleeping, increased fussiness in children.

Anatomy of the Ear

External Ear: Comprises elastic cartilage, includes the auricle (pinna) and auditory canal; collects and transmits sound.
Middle Ear: Separated from the external ear by the tympanic membrane; contains malleus, incus, and stapes bones; connected to the nasopharynx via the eustachian tube for pressure equalization.
Inner Ear: Fluid-filled structures (bony labyrinth) including the vestibule, semicircular canals, and cochlea; responsible for sending sound vibrations to the brain.

Health Assessment

Gather subjective data: hearing troubles, use of hearing aids, symptoms like tinnitus or ear drainage, dizziness or balance issues.
Conduct external observations: examine ear position, symmetry, lesions, drainage, or tenderness.
Common Symptoms to Note: Ear pain, trouble hearing, fluid drainage, fever, loss of balance, headache, loss of appetite.

Anatomy of the Nose

Lower two-thirds consist of flexible cartilage; upper third composed of rigid bone.
Merges internally with the pharynx, divided into nasopharynx, oropharynx, and laryngopharynx.

Parts of the Nose

Bone: Forms the hard upper bridge of the nose.
Hair and Cilia: Trap dirt and particles, facilitating removal through sneezing or wiping.
Lateral Walls: Cartilage outer walls covered in skin, forming nasal cavities and nostrils.
Nasal Cavities: Two hollow spaces lined with mucous membranes for air flow.
Nerve Cells: Responsible for the sense of smell through brain communication.
Nostrils (Nares): Openings to nasal cavities located on the face.
Septum: Bone and cartilage structure separating nasal cavities.
Sinuses: Four pairs of air-filled pockets connected to nasal cavities, produce moisture-retaining mucus.
Turbinates (Conchae): Three pairs located along nasal cavity sides; aid in warming and moistening inhaled air.
