An ENT doctor focuses on the medical and surgical management and treatment of patients with diseases of the ear, nose, and throat (ENT) and related structures of the head and neck. 

• Ear: ENT specialists address conditions affecting the ears, causing hearing impairment, and balance issues. They treat ear infections, balance disorders, ringing in the ears (tinnitus), and ear pain.
• Nose: Conditions affecting the nose, nasal cavities, and sinuses can lead to problems with the sense of smell, breathing, and physical appearance. ENT specialists manage allergies, deviated septum, rhinitis, sinusitis, sinus headaches, migraines, nasal obstruction, and perform related surgeries.
• Throat: ENT specialists manage conditions affecting the throat, causing speech, eating, and swallowing difficulties. They treat sore throat, hoarseness, gastroesophageal reflux disease (GERD), infections, throat tumours, airway, and vocal cord disorders.
• Head and Neck: Issues affecting the neck and head, such as diseases, tumours, trauma, and deformities of the head, neck, and face, are addressed by ENT specialists. This includes thyroid and salivary gland disorders.

Additionally, an ENT doctor can perform cosmetic and reconstructive surgery to address issues in these areas.
