EAR 9 | Diseases of the External Ear: From Otitis Externa to Anotia

Описание: Welcome to MedMghwary, where we dive deep into the fascinating world of medical education! In this video, we explore the intricate diseases of the external ear, shedding light on the pathology of the ear that affects countless individuals worldwide. From common conditions like otitis externa (swimmer’s ear) to more complex disorders such as secretory otitis media and congenital anomalies like anotia and microtia, this video is your ultimate guide to understanding these conditions.

Join us as we break down the causes, symptoms, diagnosis, and treatment options for various diseases of the ear, including:

Otitis Externa: Acute and chronic inflammation of the ear canal, often caused by infections or allergies.
Necrotizing (Malignant) Otitis Externa: A severe, potentially life-threatening infection that can spread to surrounding tissues.
Otitis Media with Effusion (Secretory Otitis Media): Fluid buildup in the middle ear without signs of acute infection, leading to hearing difficulties.
Anotia: The complete absence of the external ear, a rare congenital condition.
Microtia: Underdevelopment of the external ear, often associated with hearing loss.
Impacted Cerumen: Excessive earwax buildup causing discomfort and hearing impairment.
Eczematoid Otitis Externa: Dermatological conditions like eczema or psoriasis affecting the ear canal.
Otomycosis: Fungal infections of the ear canal, often seen in warm, humid climates.
Exostosis (Surfer’s Ear): Bony growths in the ear canal due to repeated cold water exposure.
Foreign Bodies in the Ear Canal: Common in children, leading to irritation or infection if untreated.
Tumors of the External Ear: Benign (e.g., osteomas) and malignant (e.g., squamous cell carcinoma) growths.
Trauma to the External Ear: Injuries like hematomas or lacerations affecting the auricle or canal.
Keratosis Obturans: Abnormal accumulation of keratin in the ear canal, causing pain and hearing loss.
Perichondritis: Infection of the cartilage of the auricle, often following trauma or piercing.
Congenital Anomalies: Beyond anotia and microtia, including conditions like preauricular sinuses and tags.
We’ll also discuss the pathology of the ear, exploring how infections, environmental factors, and genetic conditions contribute to these diseases. Whether you're a medical student, healthcare professional, or simply curious about ear health, this video offers valuable insights in an easy-to-understand format.
