Study Notes
External Auditory Canal Hematoma
- Treatment includes aspiration in mild cases.
- Incision and drainage under aseptic conditions.
- Pressure dressing is also part of the treatment.
- Silastic suturing may be needed to prevent reaccumulation.
- All treatment options should be performed with antibiotics.
Congenital Anomalies
- Aural atresia refers to the absence or incomplete formation of the external ear canal.
External Otitis
- Most common organisms: Aspergillus, Candida, or a mix of both.
Symptoms of External Otitis
- May be indistinguishable from bacterial otitis externa.
- Pruritus and itching deep within the ear.
- Dull ear pain may occur.
- Hearing loss due to debris obstructing the ear canal.
- Tinnitus can occur in some cases.
Signs of External Otitis
- Erythema of the ear canal.
- Mild edema is present.
- White or gray debris is indicative of Candida.
- Black spores with fungal hyphae are indicative of Aspergillus.
External Otitis Treatment
- Thorough cleaning of the ear canal.
- Dry water precautions should be followed.
- Topical antifungals are used.
- Nystatin is used to treat Candida.
- Clotrimazole is a broad-spectrum antifungal.
Malignant External Otitis
- A potentially life threatening infection of the ear canal and surrounding structures.
- Often considered an infection of the skull base.
- Commonly seen in poorly controlled diabetics and immune comprised patients.
- Pseudomonas aeruginosa is the usual causative microorganism that spreads to the bone.
- Can cause periostitis, osteitis, and osteomylitis of the skull base.
Symptoms of Malignant External Otitis
- Found in poorly controlled diabetics.
- Deep seated otalgia is common.
- Chronic otorrhea that is unresponsive to usual treatments.
- Aural fullness may occur.
Signs of Malignant External Otitis
- Inflammation and granulation tissue in the canal floor.
- Purulent secretions are present.
- Occluded ear canal.
- Cranial nerve palsies, including the facial nerve (VII), may occur.
- Nerves exiting the jugular foramen (IX, X, XI) can be involved as the infection spreads across the skull base.
Imaging of Malignant External Otitis
- Computerized tomography.
- Bone scans:
- Technetium-99m reveals bone infection.
- Gallium scan is used for monitoring treatment.
- Magnetic Resonance Imaging (MRI).
Malignant External Otitis Treatment
- Strict glycemic control for diabetic patients.
- Intravenous antibiotics for at least eight weeks with monthly gallium scans.
- Antipseudomonas drugs such as quinolones are used.
- Local canal debridement until healing is complete.
- Pain control measures.
- Surgical debridement for refractory cases.
Ramsay Hunt Syndrome
- Also known as Herpes Zoster Oticus.
- A Herpes Zoster virus infection of the geniculate ganglion of the facial nerve.
Ramsay Hunt Syndrome Treatment
- Antiviral agents, such as acyclovir or famciclovir for about one week.
- Steroids, such as prednisone, for 10-14 days in tapered doses.
- Pain medications.
Ear Wax (Cerumen)
- Composed of secretions from the ceruminous and sebaceous glands with desquamated skin cells.
- Located in the cartilaginous portion of the external auditory canal.
- Color of wax varies from yellow to brown, gray or black when mixed with desquamated epithelium and dried.
- Removal methods:
- Ear syringing for soft wax.
- Suction clearance for hard wax.
