Chronic Non Suppurative Otitis Media
- Definition: A chronic inflammatory condition of the middle ear characterized by chronic eustachian tube dysfunction, mucosal hypertrophy, and atelectasis of the tympanic membrane.
- Types:
- Eustachian catarrh: A condition characterized by chronic eustachian tube obstruction, leading to eustachian tube dysfunction.
- Serous otitis media: A condition characterized by the presence of fluid in the middle ear cleft without any evidence of infection.
- Atelectasis of tympanum: A condition characterized by the collapse of the tympanic membrane due to eustachian tube dysfunction.
- Tympanosclerosis: A condition characterized by the deposition of collagen and calcium in the tympanic membrane.
Eustachian Catarrh
- Definition: A condition characterized by chronic eustachian tube obstruction.
- Causes: Allergies, cold, sinusitis, and adenoid hypertrophy.
- Clinical features: Nasal congestion, eustachian tube dysfunction, and hearing loss.
- Investigations: Nasal endoscopy, eustachian tube function test.
- Complications: Serous otitis media, hearing loss, and eustachian tube dysfunction.
- Management: Treatment of underlying cause, eustachian tube exercise, and hearing aid.
Serous Otitis Media
- Definition: A condition characterized by the presence of fluid in the middle ear cleft without any evidence of infection.
- Causes: Eustachian tube dysfunction, allergies, and cold.
- Clinical features: Hearing loss, eustachian tube dysfunction, and pressure sensation in the ear.
- Investigations: Otoscopy, tympanometry, and pure tone audiometry.
- Complications: Hearing loss, eustachian tube dysfunction, and chronic suppurative otitis media.
- Management: Treatment of underlying cause, eustachian tube exercise, and hearing aid.
Atelectasis of Tympanum
- Definition: A condition characterized by the collapse of the tympanic membrane due to eustachian tube dysfunction.
- Causes: Eustachian tube dysfunction, allergies, and cold.
- Clinical features: Hearing loss, eustachian tube dysfunction, and pressure sensation in the ear.
- Investigations: Otoscopy, tympanometry, and pure tone audiometry.
- Complications: Hearing loss, eustachian tube dysfunction, and chronic suppurative otitis media.
- Management: Treatment of underlying cause, eustachian tube exercise, and hearing aid.
Tympanosclerosis
- Definition: A condition characterized by the deposition of collagen and calcium in the tympanic membrane.
- Causes: Chronic otitis media, eustachian tube dysfunction, and trauma.
- Clinical features: Hearing loss, eustachian tube dysfunction, and pressure sensation in the ear.
- Investigations: Otoscopy, tympanometry, and pure tone audiometry.
- Complications: Hearing loss, eustachian tube dysfunction, and chronic suppurative otitis media.
- Management: Treatment of underlying cause, eustachian tube exercise, and hearing aid.
Blood Supply
- The tympanic membrane receives blood supply from the arteries of the external auditory canal, including the anterior tympanic artery and the posterior tympanic artery.
Nerve Supply
- The tympanic membrane receives nerve supply from the auriculotemporal nerve and the nerve of the tympanic membrane.
Clinical Anatomy
- The tympanic membrane is a thin, semi-transparent membrane that separates the external auditory canal from the middle ear cleft.
- The eustachian tube opens into the middle ear cleft and is responsible for equalizing the pressure between the external auditory canal and the middle ear cleft.
