Hello and thank you for posting your query.
The CT report of your 7 year old daughter indicates that all her sinises are inflammed. There are four set of sinuses
in head known as maxillary sinus, frontal sinus, sphenoid
sinus and ethmoid sinus
These sinus provide resonance and make the head light.
These sinus communicate with nasal cavities and through the nasal cavity
with the ear.
The inflammation has spread from sinuses to the ear.
Choleastetoma means extention of skin into the middle ear where it is not normally present. This occurs secondary to inflammation.
You will be requiring antibiotics for this problem.
Your specialist will examine your daughter and will have a better idea about the problem.
I hope my answer is of help to you.
