Study Notes
Ear Pain Symptoms
- Ear pain can indicate potential infections or issues with the auditory system.
- Common symptoms include:
- Trouble hearing sounds or responding
- Drainage of fluid from the ear
- Loss of balance
- Fever of 100°F (38°C) or higher
- Headaches and loss of appetite
Anatomy of the Nose
- The external nose is made of flexible cartilage (lower two-thirds) and rigid bone (upper one-third).
- Internally, the nose connects posteriorly to the pharynx, divided into nasopharynx, oropharynx, and laryngopharynx.
- Key structures of the nose:
- Bone: hard bridge at the top of the nose.
- Hair and Cilia: trap dirt and move particles out of the nasal passages.
- Lateral Walls: made of cartilage, forming nasal cavities and nostrils.
- Nasal Cavities: two hollow spaces lined with mucous membranes allowing airflow.
- Nerve Cells: convey the sense of smell to the brain.
- Nostrils (Nares): openings to the nasal cavities.
- Septum: separates nasal cavities, made of bone and cartilage.
- Sinuses: four pairs connected to nasal cavities, producing mucus to keep the nose moist.
- Turbinates (Conchae): three pairs assist in warming and moistening inhaled air and help with drainage.
Health Assessment of the Nose
- Health history questions include duration of symptoms, treatments used, factors improving/worsening conditions, other health issues, and current medications.
- Signs to assess for sinus issues:
- Sinus Infection: chronic yellow/green discharge, decreased smell, facial pain, runny nose, headache.
- Nasal Allergies: runny nose, sneezing, itchy/red eyes or nose.
- Nasal Obstruction: difficulty breathing through one side.
Physical Examination Techniques
- Inspection: observe the nose's size, shape, symmetry, color, and any discharge.
- Nasal Cavity Examination: check for patency, exudate, and health of the mucosa.
- Palpation: assess for pain, tenderness, and swelling of the nose and sinuses.
Ear Anatomy
- External Ear: includes the auricle (pinna) and auditory canal; collects and transmits sound.
- Middle Ear: separated from the external ear by the tympanic membrane; contains ossicles (malleus, incus, stapes) and connects to the nasopharynx via the Eustachian tube for pressure equalization.
- Inner Ear: features fluid-filled spaces (bony labyrinth) containing vestibule, semicircular canals, and cochlea, responsible for converting sound vibrations into nerve impulses sent to the brain.
Health Assessment of the Ear
- Subjective data questions evaluated include hearing difficulties, use of hearing aids, presence of symptoms like tinnitus or ear drainage, and dizziness.
- External Observations: observe ear position, symmetry, lesions, and tenderness, especially around the auricle and mastoid area.
Summary Notes
- Understanding both ear and nose anatomy is crucial for identifying symptoms and conducting effective health assessments.
- A detailed physical examination helps pinpoint issues related to ear and nose health, guiding further treatment.
