Q

which is more common syndromic or non syndromic hearing loss

A

non syndromic is 70% of congenital hearing loss cases. Its due to genetic mutations of connexin genes found on ch13 (SNHL)

Q

cholesteatoma is

A

s an abnormal skin growth that can develop in the middle ear. It usually begins as a collection of dead skin cells and develops into a cyst-like pocket behind the eardrum. It can significantly impair a person’s hearing and balance, as well as the function of their facial muscles.
