The foreign bodies in the ENT field are very common disease. The kind of foreign bodies are closely related with our life style and was represented according to culture, habit, and economical status. We analyzed retrospectively 272 cases with foreign bodies in the upper aerodigestive tract and the external auditory canal which were diagnosed and managed at the Department of Otolaryngology Chungbuk National University from Jan. 1992 to Dec. 1994. We could divided 272 cases to the three groups; Group I was 212 cases(77.9%) that the patients had foreign bodies in the external auditory canal, nasal cavity, and pharynx which didn't need to be admitted, Group II was 57 cases(22%) that the patients had esophageal foreign bodies, and Group III was 3 cases(1.1%) that the patients had bronchial foreign bodies. The most prevalent age group was under 5 years old(32.3%). The overall ratio of male and female was 1.24 : 1, and the overall ratio of urban and rural ratio was 2.31 : 1. The ratio of esophageal foreign bodies and bronchial foreign bodies was 19 : 1. The incidence of sorts of foreign bodies in Group I was fish bone(41.07%), insect(25.9%), plastic bullet(8.0%), in order of frequency. The locations of foreign bodies in Group I was external auditory canal(36.8%), the tonsil(26.9%), nasal cavity(17.0%), tongue base(10.4%) in order of frequency. The incidence of sorts of foreign bodies in Group II was coin(49.1%), chicken bone(17.5%), fish bone(15.8%), in order of frequency. The main location of foreign bodies in Group II was the first narrowing(78.9%). In the Group III, the foreign bodies were corn, peanut, and apple. One patient who was arrived too late was died.

The bronchoscopy is usually performed in the patients who present symptoms of wheezing, hemoptysis, signs of airway obstruction, unexplained long-term chronic cough with or without radiologic features of pneumonia, emphysema or atelectasis. The symptoms and signs of cases of suspected airway foreign body are of often cofused with those of asthma pneumonia and other respiratory tract disease. The ventilating bronchoscopy will be helpful for removal of certain foreign bodies as well as alleviating medically-unresponsive bronchopulmonary conditions via removing abnormal secretions or merely improving ventilation. The authors have performed clinical analysis of 59 patients who were suspected of airway foreign bodies and treated by ventilating bronchoscopy from September 1985 to February 1995. The results were as follows: 1) Among the 59 cases of bronchoscopy, 51 cases(97%) were under the age of 3. The ratio of male and female was 2.69:1 2) Most common presenting symptom was coughing(84.7%) followed by dyspnea, fever, wheezing and anterior chest pain. 3) Among 39 cases of identified foreign bodies, abnormal findings in the chest X-ray films were found in 33 cases(84.6%) and most common abnormal radiologic feature was pneumonia in 10 cases(25.6%) followed by combination of pneumonia and emphysema, or emphysema alone. All the 20 cases of absent foreign body presented abnormal radiologic features and common findings were pneumonia and atelectasis. 4) Vegetable foreign bodies were the most common form of removed airway foreign bodies(69.2%) followed by metallic foreign bodies(12.8%) and plastic foreign bodies(7.7%). 5) By distribution of the location of foreign bodies, 29 cases(74.4%) were located in the main bronchus( 16 cases of right side and 13 cases of left side), 8 cases were in the trachea and 2 cases were found at the cordal level. 6) By duration of foreign body lodgement in the airway, 9 cases(23.1%) were removed within 7 to 30 days, 10 cases(5.6%) within 3 days and 5 cases(12.8%) were enlodged over 30 days. 7) In the cases of absent foreign bodies, common bronchoscopic findings were mucopurulent or thick mucoid discharge in the main bronchi, erythema or edema of bronchial mucosa and all the cases were improved after ventilating bronchoscopy with concomitant medical management.

The practice of oral surgery or other dentistry possesses the danger of causing the loss of foreign bodies used within the oral cavity. If such foreign bodies would be lost, they could enter the viscera through the esophagus or tracheobroncheal tree. Ingestion is four times as frequent as aspiration and 80% to 90% of ingested foreign bodies will pass through the body spontaneously. Once the aspiration or ingestion of foreign bodies is happened, a dental procedure should be discontinued immediately. If symptoms of respiratory distress, including coughing, wheezing, or stridor, are present, a patent airway should be maintained, oxygen administered, and ventilation supported if necessary. The PA chest radiograph will identify the objects in the lung, esophagus, or stomach. Ingested gastrointestinal foreign bodies may be managed by observation, endoscopy, and or surgical intervention and aspirated tracheobroncheal foreign bodies may be managed by bronchoscopy, and or surgical intervention. This case report describes the management of ingested or aspirated foreign bodies happened to the three patients during intraoral treatment. we recommend that the preventive method of ingestion or aspiration of the dental foreign bodies should be performed prior to intraoral treatment and the immedieate measures should be carried out after ingestion or asipiration of it.

The radiologic and clinical findings of foreign bodies in the chest of children are well recognized. Foreign bodies in adults are infrequent, however, and the radiologic findings of these unusual circumstances have rarely been described. We classified various thoracic foreign bodies into three types according to their cause: Type I, Aspiration, Type II, Trauma or Accident; Type III, Iatrogenic. This pictorial essay will illustrate the radiologic findings and consequences of thoracic foreign bodies in adults, which have rarely been described in the radiologic literature. The clinical significance of thoracic foreign bodies will be also be discussed.

This study was retrospectively investigated the clinical features, diagnostic imaging, treatment, and prognosis of foreign bodies according to alimentary site and type of foreign body, in 143 dogs. Among 28 breeds, Maltese, Shih Tzu, and terriers including the Yorkshire terrier were presented with high prevalence. Bone was the most commonly identified (33%) foreign body regardless of alimentary site. Approximately 76% of foreign bodies were in the stomach and small intestine. All esophageal foreign bodies were diagnosed on survey radiography, with the most common location being the caudal thoracic esophageal segment. Further diagnostic examinations including ultrasonography or contrast studies were additionally performed to detect radiolucent foreign bodies and perforation or leakage in the stomach and intestine. However, most seeds could be identified based on the characteristic features such as hyperdense thin double lines and inner gas on survey radiography. In conclusion, complications such as peritonitis and intestinal perforation were mainly observed in cases with seeds and linear foreign bodies. Especially, fabric foreign bodies could be induce peritonitis and re-perforation with high prevalence after surgical correction.

Background and Objectives: Foreign bodies of upper aerodigestive tract are common problem for primary care physicians. Delayed diagnosis or failure of removal might cause fatal problemsand complications. Therefore proper diagnosis and management is imperative. In this study, we described clinical features of upper aerodigestive tract foreign body, and analyzed efficacy of different management modality. Materials and Methods: 250 cases of foreign bodies in the esophagus and trachea, between Jan. 1998 through Jan. 2009 has been retrospectively analyzed. A total of 24 cases and 226 cases had been found each as airway foreign bodies and esophageal foreign bodies. The clinical features are described and treatment outcomes, prognosis, and rate of complications of each management modality have been compared. Results: In airway foreign bodies, ventilating bronchoscopy yielded better results, 19 success out of 19 trials than fiberoptic bronchoscopy, 3 success out of 5 trials. Hospitalization days after removal of foreign body didn't show difference between two treatment modalities, although patients who had ventilating bronchoscopy had gone through general anesthesia. And there was no complication after removal of foreign body. In esophageal foreign bodies, rigid esophagoscope yielded better results, 99% of successful removal rate, compared to the EGD, only 78% of successful removal rate. There was no difference of hospitalization days between two modalities. And complication rate was even low in patients who had done rigid esophagoscopic foreign body removal. Conclusion: In upper aerodigestivetract foreign body. Rapid diagnosis and successful foreign body removal is important. Removal by rigid scope(ventilating bronchoscope, rigid esophagoscope) revealed less failure in both airway and esophageal foreign bodies.

Ingestion of foreign bodies (FBs) is a common phenomenon among young children. Plain radiography is the first step diagnostic modality to detect the radio-opaque FBs. And computed tomography has been recommended by several guidelines as useful modalities for diagnosing ingested FBs. However, there is a risk of radiation exposure, making it burdensome to use in asymptomatic patients. Ultrasound (US) is not a commonly used technique for diagnosing ingested foreign bodies. However, US can provide real-time imaging with good resolutions without radiation exposure in pediatric patients. Herein, we report two pediatric cases of metallic foreign body ingestion that were successfully diagnosed using US for localizing foreign bodies. This study indicates that US may be used as an alternative method for detecting the localization of metallic foreign bodies in the gastrointestinal tract without exposure of radiation, particularly in pediatric patients.

Purpose: Computed tomography theoretically should improve detection of foreign bodies and provide more information of adjacent soft tissues. And the CT scanner and PACS program proved to be an excellent instrument for detection and localization of most facial foreign bodies above certain minimum levels of detectability. The severity of injury in penetrating trauma to the face, it is often underestimated by physical examination. Diagnosis of a retained foreign object is always critical. Methods: From March, 2005 to February 2008 a study was done with 200 patients who had facial trauma. Axial and coronal CT images were obtained with a General Electric(Milwaukee, Wis) 9800 CT scanner at 130 kV, 90 mA, with a 2-mm section thickness and a $512{\times}512$ matrix. Results: Axial and coronal CT images at various window widths should be used as the first imaging modality to detect facial foreign bodies. The attenuation coefficients for the metallic and nonmetallic foreign bodies ranged from -437 to +3071 HU. As a general rule, metallic foreign bodies produced more Hounsfield artifacts than nonmetallic foreign bodies, thus providing a clue to their composition. All of the metallic foreign bodies were represented by a single peak and had a maximum attenuation coefficient of +3071 HU. Of the nonmetallic foreign bodies, glass had an attenuation coefficient that ranged from +105 to +2039, while plastic had a much lower coefficient that ranged from -62 to -35. wood had the lowest range of attenuation coefficients: -491 to -437. Conclusion: The PACS program allows one to distinguish metallic from nonmetallic foreign bodies and to individually identify the specific composition of many nonmetallic foreign bodies. This program does not, however, allow identification of the specific composition of a metallic foreign body. We recommend this type of software program for CT scanning of any patient with an injury to the face in which a foreign body is suspected.

Background : The development of bronchoscopic equipment along with the precision of radiographic techniques had reduced the mortality rate of patients with tracheobronchial foreign bodies but has been no change in the incidence of tracheobronchial foreign bodies since their introduction. The aim of this study was to assess the clinical characteristics of a tracheobronchial foreign body aspiration and to evaluate the efficacy of the treatment modality in children and adults. Methods : This is a retrospective review of 64 patients who underwent bronchoscopic procedures for the treatment of aspirated foreign bodies from December 1994 through March 2004 at the Chonnam national university hospital. Results : There were 47 males and 17 females, aged from 1 month to 78 years. Most of the patients had no underlying illness except for one patient with a cerebrovascular accident that contributed to the foreign body aspiration. The most common symptom was cough, which was noted in 54 patients (84.3%). The other presenting symptoms were dyspnea (48.8%), fever (20.3%), sputum (14%), vomiting (7.8%), and chest pain (4.6%). Those whose tracheobronchial foreign bodies were diagnosed more than 2 days after the aspiration (21 patients) were more likely to have pneumonia than those whose foreign bodies were diagnosed within 2 days (p = 0.009). Foreign bodies were visualized in the plain chest radiographs in 12 cases (18.8%), while others showed air trapping (21, 32.8%), pneumonia (15, 23.4%), atelectasis (7, 10.9%), and normal findings (9, 14.1%). The foreign bodies were more frequently found in the right bronchial tree (36) compared with the left bronchial tree (22, p = 0.04). In order to remove the foreign bodies, twenty (31.2%) cases were removed using flexible bronchoscopy, while 42 (65.6%) and 2 (3.2%) cases required rigid bronchoscopy and surgery, respectively. Conclusions : Tracheobronchial Foreign body aspiration had a bimodal age distribution in the infancy and old age around 60 years. They were found more frequently in the right bronchial tree. In addition, patients whose foreign bodies were diagnosed more than 2 days after the aspiration were more likely have a infection. Rigid bronchoscopy is the procedure of choice for uncooperative children and for those with foreign bodies lodged deeply in the small bronchial tree.
