The difference (or gap) between these two lines plotted on your audiogram is the air [conduction] – bone [conduction] gap or air- bone gap for short. For example, if your audiogram showed an air- conduction hearing loss of 70 dB while your bone-conduction test results only showed a 40 dB hearing loss for a given test frequency, then the ...

Perhaps the most important diagnostic feature of the audiogram is the air-bone gap. By distinguishing between conductive and sensorineural impairments, the air-bone gap profoundly influences the patient's care. A false air-bone gap can lead to inappropriate medical or surgical treatment.

air-bone gap. This difference is a measure of the loss in transmission across the middle ear and indicates the maximum improvement that may be obtained through successful corrective surgery. When the defect is confined to the organ of Corti, the bone-conduction audiogram shows the same…

If a bone conduction test is also needed, the results will be marked using a blue > line for the left ear and a red < line for the right (not pictured below). The difference between the results of air conduction and bone conduction tests is known as the air-bone gap. An air-bone gap may mean a problem in the outer or middle ear.

INTRODUCTION. An air-bone gap (ABG) is defined as the difference between air-conduction and bone-conduction audiometric thresholds. ABGs are found in patients with conductive (CHL) or mixed (MHL) hearing loss generally attributed to outer- and/or middle-ear diseases such as otitis externa, tympanic membrane perforation, interruption or fixation of the ossicular chain, and …

conduction thresholds are both abnormal, but air conduction threshold are worse than bone conduction thresholds (an air-bone gap is present). Degree (or severity) of hearing loss is determined by looking at where one’s pure tone air conduction thresholds were obtained (and are plotted on the audiogram). Degree of hearing loss can be calculated

Normal bone conduction thresholds indicate that this 30dB air-bone gap is a case of mild-to-moderate conductive hearing loss. ADHEAR would be an effective non-surgical solution for temporary conductive hearing loss, or chronic conditions such as damaged ossicles, chronic otitis media, or other causes of conductive hearing loss.

Lines may be used to connect symbols on an audiogram. When used, a solid line should connect the air conduction threshold. Typically, bone conduction thresholds are not connected by lines, especially when no air-bone gap is present. In cases of an air-bone gap, a dashed line can be used to connect bone conduction thresholds.
