Study Notes
General Overview of EENT Disorders
- Common disorders include issues related to the eyes, ears, nose, and throat.
- Most patients can be managed in primary care settings, though some require specialist referrals.
Eye Diseases and Conditions
- Keratitis: Inflammation of the cornea.
- Dacryocystitis: Infection of the tear sac.
- Uveitis: Inflammation of the uveal tract.
- Endophthalmitis: Inflammation within the eye, usually due to infection.
- Chalazion: Painless eyelid lump from a blocked Meibomian gland.
- Hordeolum (Stye): Painful infection of an eyelid gland.
- Hyphema: Blood in the anterior chamber of the eye.
- Corneal Abrasion: Scratch on the cornea surface.
- Retinal Detachment: Separation of the retina from underlying tissues.
- Acute Angle Closure Glaucoma: Sudden increase in intraocular pressure.
Risk Factors and Treatment
- Chalazion: Often self-limited; management includes warm compresses and baby shampoo scrubs. If unresolved in 4-6 weeks, consider referral for drainage.
- Bacterial Keratitis: Primary risk is contact lens wear; treated with antibiotics like Vancomycin.
- Optic Neuritis: Early indicator of multiple sclerosis.
Anatomy of the Ear
- Composed of three anatomical sections: outer, middle, and inner ear.
- Sound waves travel through the ear canal to the tympanic membrane, setting up vibrations captured by ossicles, which transmit them to the cochlear duct.
Hearing Loss Considerations
- Causes of hearing loss can be conductive (related to mechanical transmission issues) or sensorineural.
- Common conductive issues include cerumen buildup, otitis externa, and tumors.
- Ototoxic Drugs: Certain medications can cause hearing loss, including aminoglycosides (Gentamicin, Streptomycin), antimalarials, and some diuretics, usually reversible upon discontinuation.
Patient Assessment
- Important to take comprehensive history regarding hearing loss.
- Encourage patient to rate pain levels for accurate assessment.
- Be mindful of any potential exposure to ototoxic substances that may affect hearing.
