Hello,
Usually in adults, tonsillar abscess is associated with other symptoms of upper
respiratory tract like cough, fever with chills, cold,
sneezing, severe malaise, and difficulty in swallowing. As he was given IV antibiotics and
steroids, infection or tonsillar abscess must have gone.
Other investigations that may help are:
1) Modified barium swallow
2) Fiberoptic laryngoscopy
3) Fiberoptic endoscopic evaluation of swallowing
You can
consult a gastroenterologist and discuss the above methods.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Pallavi M., Anesthesiologist
