Normal ear drum. A perforated eardrum (tympanic membrane perforation) is a prick in the eardrum. It can be caused by infection (otitis media), trauma, overpressure (loud noise), inappropriate ear clearing, and changes in middle ear pressure. An otoscope can be used to view the eardrum to diagnose a perforation. Perforations may heal naturally ...
Conductive hearing loss (CHL) occurs when there is a problem transferring sound waves anywhere along the pathway through the outer ear, tympanic membrane (eardrum), or middle ear . If a conductive hearing loss occurs in conjunction with a sensorineural hearing loss, it is referred to as a mixed hearing loss.
Eighth nerve deafness typically starts with high-frequency hearing loss between eight and ten years old, but can start at a younger age. [7] It may have sudden onset in one or both ears, and can progress rapidly. It can induce permanent hearing loss. [14] There may also be a deformity on the nose known as saddle nose deformity. [15]
Hearing loss is a partial or total inability to hear. [5] Hearing loss may be present at birth or acquired at any time afterwards. [6] [7] Hearing loss may occur in one or both ears. [2] In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. [8]
The link between NSAIDs and hearing loss tends to be greater in women, especially those who take ibuprofen six or more times a week. [36] Others may cause permanent hearing loss. [37] The most important group is the aminoglycosides (main member gentamicin) and platinum based chemotherapeutics such as cisplatin and carboplatin. [38] [39]
The infection may be either subacute or acute and is characterized by itching in the ear, malodorous discharge, inflammation, pruritus, scaling, and severe discomfort or ear pain. The mycosis results in inflammation, superficial epithelial exfoliation, masses of debris containing hyphae, suppuration, and pain. [2] Otomycosis can also cause ...
Most forms of nonsyndromic deafness are associated with permanent hearing loss caused by damage to structures in the inner ear. The inner ear consists of three parts: a snail-shaped structure called the cochlea that helps process sound, nerves that send information from the cochlea to the brain, and structures involved with balance.
Ototoxicity is defined as the toxic effect on the functioning of the inner ear, which may lead to temporary or permanent hearing loss (cochleotoxic) and balancing problems (vestibulotoxic). [1] Drugs or pharmaceutical agents inducing ototoxicity are regarded as ototoxic medications. Anatomy of the human ear
