Study Notes
Ear Examination
- Inspect the ear canal for discharge, redness, odor, nodules, or cysts.
- Perform an otoscopic examination to view the tympanic membrane and surrounding structures.
- The tympanic membrane should be pearl gray, glistening, and transparent; check for bulging, retraction, lesions, or perforations.
Ear Pain and Conditions
- Earaches often signal issues in the external or middle ear, linked to infection, hearing loss, and otorrhea (ear drainage).
- Common causes of hearing loss include cerumen impaction, foreign bodies, polyps, otitis media, and otosclerosis.
- Trauma can also impair the middle ear’s bony chain, affecting sound transmission.
Otitis Media
- Otitis media denotes inflammation of the middle ear, often due to eustachian tube dysfunction.
- Can be categorized as suppurative or secretory; may present as acute or chronic.
- Acute otitis media features infected fluid, with rapid onset and short duration.
- Symptoms include ear pain (especially when lying down), tugging at the ear (in children), difficulty sleeping, and increased fussiness.
Anatomy of the Ear
- External Ear: Comprises flexible cartilage, including the auricle (or pinna) and auditory canal, which collects sound.
- Middle Ear: Separated from the external ear by the tympanic membrane, which is connected to the ossicles (malleus, incus, stapes) and the eustachian tube to equalize air pressure.
- Inner Ear: Contains a fluid-filled bony labyrinth (vestibule, semicircular canals, cochlea) that converts sound vibrations into nerve impulses sent to the brain.
Ear Assessment
- Subjective questions regarding hearing troubles, use of hearing aids, symptoms like tinnitus, drainage or pain, and dizziness.
- External observations should check ears for symmetry and position, noting any lesions, drainage, or tenderness.
Red Flags for Ear Issues
- Symptoms needing attention: ear pain, hearing difficulties, fluid drainage, loss of balance, fever above 100°F, and headaches.
Nose Anatomy
- External nose: The lower two-thirds consist of flexible cartilage; the upper third is rigid bone.
- Internal nose connects to the pharynx and functions in airflow and olfaction.
Parts of the Nose
- Bone: Forms hard bridge; supports nasal structure.
- Hair/Cilia: Trap particles and move them out of the nasal passages.
- Lateral Walls: Made of cartilage and skin, forming the nasal cavities and nostrils.
- Nasal Cavities: Hollow spaces for air flow; lined with mucous membranes.
- Nerve Cells: Provide the sense of smell to the brain.
- Nostrils (Nares): Openings leading to nasal cavities.
- Septum: Divides nasal cavities; composed of bone and cartilage.
- Sinuses: Air-filled pockets producing mucus for moisture.
- Turbinates (Conchae): Help warm and moisten inhaled air and assist in drainage.
