[@141velpulasrinavyatejaswin8]

Hyperacusis is the reduced intolerance to sound and is caused by the facial nerve palsies which causes loss of protective stapedial reflex

[@mahitareddy7019]

That's causes paralysis of the stapedius muscle

[@cyanide0269]

Increased intolerance or reduced tolerance

[@cyanide0269]

Not reduced intolerance ... that just means increased tolerance to sound .. that is simply deafness

[@tanaytejus3589]

It is the enhanced sensitivity to the sound waves due to lesion in stapedius branch of facial nerve

[@viral_edits99]

Hyperacusis can be due to injury of facial nerve above origin of nerve to stapedius or due to injury of nerve to medial pterydoid supplies (tensor tympani).

[@121nitishapareek6]

Great!!🙌

[@sandeepchoudhary7855]

Explanations 🔥🔥🔥🔥

[@sparksfly759]

Thank you sir!!

[@faizmudassir5011]

really amazing fantastic

[@sheetalkatoch2997]

Thankyou sir ✨

[@piyushsethiya5295]

Paralysis of stapedius muslce causes wider ranger of osscilation, leading to hyper-reaction of auditory ossciles to sound vibration. This condition is called hyperacusis. Paralysis of stapedius muscle occurs in lesion of facial nerve

[@simrank29]

What a coincidence sir!
I just came to understand this topic only..and u talked abt India Australia match in video...that was held today also!!😁😁

[@85-subhadrapanda80]

Injury to facial nerve- branch is nerve to stapedius
Or injury to Medial ptetygoid branch of Mandibular nerve, supplies Tensor tympani.
Or other reasons that affect attenuation mechanism cause Hyperacusis

[@Aiming-zw8xo]

Tq sir ❤❤ lots of love

[@alanothomas8563]

awesome flowchart

[@shaziafarooq7804]

Sir Loudness of sound has no relationship with its frequency ..... And if there's some relation please let me clear it

[@aniteshroychowdhury1227]

Injury of nerve to stapedius, branch of facial nerve

[@harshapriyabandaru9466]

Sir types of hypoxias bhi explain kar dijiye😁

[@shekharsuman300]

Simple n Concise !! 👍👍

[@_komal18]

Thank you sir

[@ayushigouri7699]

Injury or paralysis of nerve to stapedius

[@agkomal2002]

Facial nerve palsy. Nerve to stapedius is affected.

[@diotpit5842]

Notes where

[@Vishnu-Prasath]

Facial Nerve which supplies Stapedius muscle

[@zoyanoonari9289]

Due to injury of nerve to stapedius which is branch of facial nerve.

[@thefactfactory898]

sir...it is due to damage in inner ear..for ageing process...is it correct??

[@AkshatJuneja]

Yupp

[@arunsharma3016]

Pinna external auditory canal tympanic membrane

[@tejeswarpavan7650]

Nerve to stapedius a branch of facial nerve

[@gokult.r9219]

Paralysis of stapedius

[@awaisahmed7400]

It is outward movement of malleus not stapes

[@awaisahmed7400]

Stapes moves inwards

[@shannuneeha2552]

Injury to nerve to stapedious

[@nivethasenthil9644]

Hypercusis is excessive hearing due to intolerance to loud sounds

[@bhargavithakrar9532]

When attenuation mechanism is damaged at that time?

[@AkshatJuneja]

Yupp

[@adhithyarider1323]

Due to damage of stapedius muscle

[@maximuslonsdale9499]

anda perlu melaraskan kandungan

[@neha6931]

It is a damage of nerve connection between ear and brain.

[@palakbhanushali4499]

Sir u have explained from which book

[@pearlshah7236]

visual: lateral geniculate body
auditory: medial geniculate body

[@mohammadshehbazuddin8031]

Hope you are prepared for paper 2 physiology 😂 ATB

[@pearlshah7236]

@@mohammadshehbazuddin8031 prepared? And that tooo physiology? Is it ever sufficient 😂😂

[@raushniriya8296]

Stapedius

[@sanketnawghare7601]

Watch ur speed......!!!!!!!

[@harshmarathe1288]

Injury to stapedial branch of Facial

[@harshmarathe1288]

P.S. Same reason for Hyperacusis in Ramsay Hunt Syndrome - Herpes infection of geniculate ganglion. , Is there any specific condition like this for damage of nerve to medial pterygoid ???(supplying tensor Tympani )

[@AkshatJuneja]

Tonic tensor tympani syndrome (TTTS) can cause TT spasm leading to tinnitus and hyperacusis.It is due to an overlying anxiety disorder, which causes a reduction in the threshold required to trigger the TT muscle reflex.
All the best for tomorrow :)
