Hi,
Noted the history about your 15 months daughter getting recurrent blood tinged pus from ear, the Doctor suggested small surgery for the possible
cyst.
Yes, as per the history you have provided this seems to be a auricular
sinus hence the recurrence.
The best possible treatment is as follows:
First of all, get a proper diagnosis by taking an opinion of an ENT Surgeon as he is most exposed to such diseases and surgery.
If required a sinogram will help to establish the diagnosis and also get the extent of the cyst.
Proper antibiotic and anti-inflammatory cover till the infection settled.
Surgery under microscope gives better chance to get a cure.
Till then apply Liquid
povidone iodine locally to keep the area sterile.
Stop feeding the baby in laying down position.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, ENT and General Surgeon
