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.
