A foreign body (Latin: corpus alienum) is any object originating outside the body. Of all specialties, otolaryngology covers the greatest number of natural body orifices, making foreign bodies a common diagnosis. Foreign bodies of the ear canal and nose often occur in children and are easily accessible during physical examination. Foreign bodies of the oral cavity and oropharynx are also easily removed. Esophageal and tracheobronchial foreign bodies are common in children and the elderly. A number of rigid and flexible endoscopic techniques are available for foreign body removal. In Germany, flexible endoscopy is six times more common than rigid endoscopy. Both methods are highly effective, and each has its advantages in certain situations. Rigid endoscopy is still a key in otolaryngology and can be used in case of failure of flexible techniques. It is therefore important for otolaryngologists to be proficient in both techniques.
