thanks for your query.
Opacification in sinuses s/o chronic sinusitis
and yes its a main cause for hearing loss
. As it spreads to middle ear through eustachian tube, causing middle ear effusion
and changes of inflammation in mastoid antrum.
Needs topical nasal steroidal spray like mometasone nasal spray
and gromet if impedance audiometry s/o middle ear effusion.
Many thanks, take care.
