Otorhinolaryngology is a medical-surgical specialty that covers a wide field of study and surgical activity over the complex area of the upper aerodigestive tract. This specialty addresses the ears, nose, pharynx, larynx, neck pathology, and salivary glands. Conditions affecting these interconnected regions are studied collectively due to their close association.

Otorhinolaryngology is fundamental to communication, as it involves the organs of hearing, smell, and taste, which receive environmental information. The specialty encompasses all necessary theoretical and practical knowledge for diagnosing and treating infectious, oncological, traumatic, congenital, and degenerative conditions of the ears, nostrils, paranasal sinuses, pharynx, and larynx.
