Hi Radio 247....
You have developed pansinusitis and may be some add-on infection in the sinuses
Sinuses are empty spaces in our facial and skull base bones which are lined by mucosa-thin protective membrane. These cavities make the bones lighter and give our voice a typical tone.
When we get an attack of cold
there is change in our usual tone because there is inflammation and thickening of this mucosa,its cause is mostly viruses-adeno and rhino viruses in particular. Other frequent causes include allergic rhinitis-seasonal/perennial, vasomotor rhinitis
, chemical fume induced rhinitis.
Probably you had this problem for longtime and left it untreated so now it has spread to the extent as to warrant a surgery.
I would advise you to follow the advice of operation from your surgeon asap because the kind and extent you have usually results in excessive exudation from mucosa and the secretions are not drained effectively due to hypertrophic mucosae and this also blocks the ostia- the small opening through which the sinuses actually drained.
The mucosa needs to be debulked surgically so that normal physiology can be restored otherwise serious infection may crop up and due to proximity to brain, there is fairly high risk of meningoencephalitis
and brain abscess
Surgery is highly recommended and it's off course a major surgery but today anesthesia
is fairly safe and you can expect an uneventful recovery.
