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.
