Otolaryngology is a medical specialty that focuses on the diagnosis and treatment of conditions related to the ear, nose, and throat (ENT). It also includes related areas such as the head and neck. Otolaryngologists, also known as ENT doctors, are trained to manage a wide range of conditions such as hearing loss, sinusitis, tonsillitis, allergies, voice disorders, and cancers of the head and neck. They may use a variety of diagnostic tools such as endoscopes, CT scans, and hearing tests to evaluate and treat their patients. Treatment options may include medications, surgery, or other therapies depending on the specific condition.
