Ingested foreign bodies are common occurrences in the pediatric population. From October 2002 to April 2006, eight patients (6 male, mean age: $30.9{\pm}14.4$ months, range: 7~45 months) who had ingested metallic foreign bodies, such as bar magnets, coin-type magnets, screws, metal beads, and disk batteries, were selected for foreign body removal using a magnetic device under floroscopic control. A 1-cm-long cylindrical magnet (6 mm in diameter) was placed at the end of a 150-cm-long plastic tube from an IV set. The magnet was passed through the mouth into the stomach. Under fluoroscopic control, the magnet was maneuvered so that it attached to the metallic foreign bodies. The forgeign body was then easily removed by retracting the magnet with the metallic object attached. This procedure was successful in six patients of 8 patients. This procedure is a minimally-invasive and may avoid the use of anesthesics, endoscopy or surgery.

Laryngeal foreign bodies are not common among the foreign bodies of aerodigestive tract. It is relatively easy to diagnose in acute phase of entry because of a readily\ulcorner available history of intake, and signs or symptoms referable to the foreign body in the highly sensitive air passage. However, on occasion, sudden death by respiratory failure occurs due to complete obstruction of airway. Therefore, it is common and safe to remove the laryngeal foreign bodies by suspension laryngoscope under general anesthesia after tracheostomy. Recently, the authors experienced a case of metallic foreign body in larynx penetrating neck, which was removed by suspension laryngoscope under general anesthesia without any life threatening complication.

Endobronchial foreign bodies are difficult to diagnose as the cause of obstructive pneumonia and atelectasis, However, once discovered, they can generally be removed, leading to an immediate and dramatic resolution of the symptoms. Occasionally, small foreign bodies that lodge in the peripheral airway are often initially asymptomatic but become symptomatic several years later. We reported a case of obstructive pneumonia and massive hemoptysis caused by a foreign metallic body. The patient knew that the foreign body was lodged in the peripheral airway on the chest X-ray, but did not want treatment. Several years later, he had a massive hemoptysis and obstructive pneumonia. Removal with a flexible bronchoscope failed, but the metallic foreign body was self-expectorated by coughing after the procedure. The pneumonia was resolved after removing the foreign body. The patient improved and was discharged without any sequela.

On occasion there were reports of foreign body of paranasal sinuses. Most common site is the maxillary sinus. But it is very rare to experience a long-term foreign body in maxillary sinus. There are two types of maxillary foreign bodies according to etiology, one is caused by various traumatic accidents, and the other is iatrogenic cause which mainly retaining gauze or medical instruments after sinus operation or teeth extraction. We experienced an interesting case of over fifty yews resided metal foreign body in maxillary sinus caused sinusitis, and report with a brief literature review.

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.

The esophageal perforation with foreign body is very rare. It is usually caused by sharp metallic foreign body or bone piece and rarely caused by long standing of foreign body. The authors observed 5 cases of esophageal perforation with foreign body among 48 cases of esophageal foreign body during the period from Jan. 1976 to Dec. 1977. There were two cases of esophageal foreign body with curved wire. a case with bone piece. a case with safty pin and a case with fish hook.

Penetrating neck injuries constitute 5-10% of all trauma cases. These injuries may cause life-threatening suppurative or vascular complications, but the severity and extent of damage depends upon the inflicting object and the involved structures. If significant complications are not expected, then it is best to leave the foreign body embedded and avoid surgical risks. We present a rare case of a foreign body embedded in the neck causing tinnitus and foreign body sensation.

We report the case of a seven-year-old boy with an ingested foreign body, which was retained within the appendix for a known duration of ten months, ultimately requiring appendectomy. The ingested foreign body was incidentally discovered by abdominal x-ray at an emergency room visit for constipation. Despite four bowel cleanouts, subsequent x-rays showed persistence of the foreign body in the right lower quadrant. While the patient did not have signs or symptoms of acute appendicitis, laparoscopic appendectomy was performed due to the risk of this foreign body causing appendicitis in the future. A small metallic object was found within the appendix upon removal. This case highlights the unique challenge presented by foreign body ingestions in non-verbal or developmentally challenged children and the importance of further diagnostic workup when concerns arise for potential retained foreign bodies.

Foreign bodies in upper aerodigestive tract migrating into retropharyngeal space are rarely encountered emergent cases in otolaryngologic fields. A 60-years-old female presented throat pain and lump sense after a meal. Computer tomography showed metallic foreign body impacted in the retropharyngeal space. A hypopharyngeal perforation was suspected by through flexible laryngoscopy and gastrointestinal endoscopy. It was successfully removed by external cervical approach, and we report this case with a review of the related literatures.
