If the foreign body is small or few in number, it can be removed by blowing the nose or by sucking back the nasal mucus. If this does not work, you may need to go to the hospital to have the foreign body removed by nasal endoscopy. 1. If the foreign body is small, you can blow your nose or inhale forcefully to increase the flow rate of air through the nose to expel the foreign body. 2. If the foreign body is large in size and in a deeper location, making it difficult to remove by oneself, it is recommended to go to an ear, nose and throat specialist hospital to avoid using tools such as tweezers and pliers on your own, which can cause secondary injuries and lead to damage to the mucous membranes of the nasal cavity and worsening of the condition. If there are old or young patients, due to the body’s immune defense function, the body’s exclusion function and other system imperfections, making it difficult to expel the foreign body by themselves, it is recommended to go to the outpatient emergency clinic, with the help of the relevant equipment, to remove the foreign body in the nasal cavity, so as to avoid causing secondary damage and delay the condition.
