Hearing loss

DefinitionWHO recommened thatThe term Deaf should be applied when the sense of hearing is non functional for ordinary purposes of life.

Hearing loss more than 90

Hearing loss

Classification of hearing lossTwo types : Non-organic and OrganicNon-organic : two types 1. Malingering 2. psychogenic

Organic : three types

1. Conductive hearing loss 2. Sensorineural hearing loss

3. Mixed hearing loss

Slide5

Hearing loss

Conductive hearing loss(CHL)Any disease process which interferes with the conduction of sound to reach cochlea causes CHLMost common causes of CHLEar waxASOM

CSOM

Tympano sclerosis

OtosclerosisOtitis media with effusion (in children)

5

Slide6

Characteristics of CHL

Rinne’s test – Negative (BC > AC)Weber test – Lateralised to worst earAbsolute bone conduction – NormalSpeech understanding – Good

Intolerance to loud sound – Absent

Speech of patient – Low voice

Common associated symptom – Otorrhea/earachePure tone audiometry –

Usually lower frequencies are affected more

Air-bone gap – present

Hearing loss – Never > 60-70db

Site of lesion – External and Middle ear6

Slide7

Conductive Hearing loss

Pure tone audiometry – Usually lower frequencies are affected moreAir-bone gap – presentSite of lesion – External and Middle ear

7

Slide8

Conductive Hearing loss

Treatment Treatment of the cause1. Removal of external auditory canal occlusions Impacted wax, foreign body, tumours,

meatal

stenosis etc.

2. Myringotomy – Acute Otitis Media3. Grommet – Otitis Media with effusion

4.

Stapedectomy

– Otosclerosis

5. Tympanoplasty – TM perforations & Ossicular disruptions6. Hearing aids – When surgery is not possible, refused or failed.8

Slide9

Sensorineural Hearing loss

Results from lesions ofCochlea 8th

cranial nerve

Central auditory pathways.

Common causes of SNHLCongenital

In

fections : Labyrinthitis, Meningitis

Trauma to labyrinth and CN VIII in

fractures of temporal boneTumors : CN VIII acoustic neuromaSystemic diseases : Diabetes, Multiple sclerosis, Syphilis, hypothyroidism, Kidney disease, Autoimmune disorders.Presbycusis9

Slide10

Characteristics of SNHL

Rinne’s test – Positive (AC > BC)Weber test – Lateralised to better earAbsolute bone conduction – ReducedSpeech understanding – Poor

Intolerance to loud sound – Present in cochlear lesion

Speech of patient – Loud voice

Common associated symptom – TinnitusPure tone audiometry –

Usually higher frequencies are affected more

Air-bone gap – Absent

Hearing loss – can be >60-70 db

Site of lesion – Internal ear, CN VIII & central auditory connections10
