The external auditory canal is the only skin lined cul-de-sac in the whole human body. It is known to perform both auditory and non auditory functions. The auditory function is that it permits efficient sound transmission from the environment to the tympanic membrane, self maintenance of a clear passage for transmission of sound. Its non auditory functions include protection of the middle ear and inner ear from trauma and environmental insults. This article dwells in depth about the entire gamut of anatomy of external auditory canal.
Cystic fibrosis is an autosomal recessive disorder affecting the exocrine glands. It causes the secretions from these glands to become thick and viscous.

Benign paroxysmal positional vertigo is a commonly diagnosed condition 1. Studies reveal that this is the commonest cause of giddiness. This condition is commonly caused by dysfunction involving posterior semicircular canal. Lateral and superior canals have also been implicated rarely. It has been estimated that nearly 15-20% of all patients presenting with giddiness suffer from BPPV 2. This article attempts to review the current available literature in this topic.
This article reviews the history of tuning fork tests, its current status as a clinical examination tool. All the commonly performed tuning fork tests are discussed in detail. The three commonly performed tuning fork tests include: Rinne test, weber test and Absolute bone conduction test.
Carhart’s notch is classically seen as a dip centered around 2 kHz range of bone conduction curve audiometery. This feature is seen in patients with otosclerosis. This article attempts to discuss why this dip is caused in the bone conduction audiometry curve in these patients.
Malingering is common these days with liberal workmen compensation act. Lots of concessions are given to physically challenged these days. It is our duty to ensure that these incentives reach the deserving. In order to identify the beneficiaries we should weed out malingerers. Fortunately there are various tests which can be performed to weed them out. This article is a treatise of how to identify malingerers. It enumerates various bed side tests, tuning fork tests and objective tests to identify non organic hearing loss.
Eosinophilic otitis media is actually a recent introduction. These patients may manifest with sudden hearing loss. There may be associated bronchial asthma and allergic rhinitis. Diagnostic criteria of this condition are rather vague. A review of literature shows that demonstration of eosinophils in the middle ear secretion of these patients could be considered to be pathognomonic of this condition.
Malignant otitis externa is a severe debilitating disorder that involves the external auditory canal. The term “Malignant Otitis Externa” is actually a misnomer. It has been coined to indicate the destructive capabilities of this disorder. This article discusses etiopathogenesis, diagnostic problems and various management modalities available to manage the same.
