An otolaryngologist, or ENT doctor, is trained to diagnose and treat diseases of the ear, nose, mouth, larynx, throat, and the structures within the head and neck.

Plastic and reconstructive surgeons can perform both cosmetic as well as functional surgery on facial trauma resulting from accident or injury as well as treating smell disorders, polyps, nasal obstructions (deviated septums), diseases of the throat, voice disorders and disorders affecting sensory function as well.

Infections and allergies that affect the ears, nose, and throat are some of the most common conditions that Otolaryngologists treat, such as hay fever, rhinitis, chronic sinusitis, and laryngitis. There are specific disorders affecting the ear, including hearing loss, ear infections, balance problems, and tinnitus.

Otology, which examines the ear, hearing, and balance, as well as conditions such as ear infection and tinnitus, is another important sub-specialty of otolaryngology. The field of rhinology treats disorders of the nose and sinuses, including nose bleeding and loss of smell.
