According to the history of laryngeal foreign body inhalation; laryngoscopy to find the foreign body; laryngeal anteroposterior and lateral x-ray; laryngeal CT scanning, fiberoptic laryngoscopy can be diagnosed with the shape of the foreign body, the location of the foreign body and embedded condition, which can provide the basis of the removal of the foreign body. Remove the foreign body, the methods are as follows: 1, indirect laryngoscopy or fiberoptic laryngoscopy under the removal of foreign objects Applicable to the foreign body is located in the laryngeal vestibule or above, can cooperate with the patient. After surface anesthesia of the laryngeal mucosa, the foreign body is removed under indirect laryngoscopy, and small foreign bodies can also be removed under fiberoptic laryngoscopy. Direct laryngoscopy can be used for both adults and children. General anesthesia can be given, and sedatives are forbidden before the operation, because they can inhibit breathing and lead to insufficient ventilation and aggravate respiratory distress. 3.In cases of large foreign body, serious airway obstruction and dyspnea, it is estimated that it is difficult to remove the foreign body under direct laryngoscopy, tracheotomy can be performed first, and after the dyspnea is relieved, general anesthesia can be administered, and then remove the foreign body under direct laryngoscopy. After laryngeal foreign body removal, antibiotics and glucocorticoid nebulized inhalation should be given to prevent the occurrence of laryngeal edema, bronchitis and pneumonia.
