What is a foreign body?

Nasopharyngeal foreign bodies may be related to unreasonable diet, degenerative changes, foreign body retention and other factors.

1. Irrational diet

includes eating too fast, overeating, talking while eating, etc., which may swallow unchewed food and bones and cores mixed in food, causing foreign body obstruction, thus causing the above abnormal conditions.

2. Degenerative changes

With age, degenerative changes may occur in tissues such as teeth and pharynx, which may cause incomplete chewing, decreased tissue elasticity, and easily lead to related discomfort symptoms.

3. Foreign body retention

For patients undergoing nose and throat surgery, cotton balls, gauze and other items may remain at the surgical site due to surgical errors, causing nasopharyngeal foreign body retention.
