title: [Clinical analysis of 249 cases of children with foreign bodies in the nasal cavity and paranasal sinus].
abstract: OBJECTIVE
  Insertion of a foreign body in the nasal cavity is a very common incident in children. It is easily diagnosed, but the type of foreign body varies and the extraction can sometimes be difficult with risk of complications. The present study reported nasal foreign bodies diagnosed in emergency in our ENT department, with an update on the state of knowledge.
  
  
  METHODS
  A prospective study between Feb 2013 to Sept 2015 included patients admitted to the ENT emergency unit for nasal foreign body. Data comprised age, gender, circumstances of discovery, symptoms, type of foreign body, extraction method and complications. Many patients required anterior rhinoscope for the diagnosis and removal (179/249, 71. 9%), and 170 cases were directly removed and 9 cases were into alimentary canal; Most irregularly shaped objects were removed by a endoscope under general anesthesia (70/249, 28.1%), including button batteries (n= 65), nasal calculi (n = 2) and chopsticks (n = 3).
  
  
  RESULTS
  The main types of foreign body were vegetal forms (61.8%). The incident was discovered following nasal symptoms in 24.9% (n = 62). Extraction was easy by using forceps, micro-hooks or suction in 71.9% of qn:Nasal sinuses foreign body on prevention, detailed history and make the necessary inspection, can improve the correct diagnostic rate.
