ENT's can do surgery and treat many different medical conditions. You would see one if you have a problem involving:

An ear condition, such as an infection, hearing loss, or trouble with balance

Nose and nasal issues like allergies, sinusitis, or growths

Throat problems like tonsillitis, difficulty swallowing, and voice issues

Sleep trouble like snoring or obstructive sleep apnea, in which your airway is narrow or blocked and it interrupts your breathing while you sleep

Infections or tumors (cancerous or not) of your head or neck
