Otolaryngology, sometimes known as ENT, is a branch of medicine that focuses on diagnosing and treating problems involving the ears, nose, throat, and other head and neck regions. Otolaryngologists are medical professionals who focus on treating disorders affecting the skin, ears, sinuses, head and neck, breathing, swallowing, and speech. Generally speaking, issues with your ears, nose, and throat don't offer any serious risks to your health, however they may temporarily affect how you live your life and frequently go away on their own. Your primary care physician can suggest an ENT specialist if your symptoms are overly bothersome, severe, or chronic.
