An 11-year-old, castrated Maltese dog presented with a 3-week history of periocular swelling, epiphora, and intermittent strabismus. On examination, a foreign body was observed in the anterior chamber, along with orbital cellulitis. Severe gingivitis and plaque accumulation were also diagnosed. The foreign body was surgically removed, and dental prophylaxis and dental extraction were performed. The foreign body entrance could not be found intraoperatively, and the foreign body, later identified as a feather, was removed through a clear corneal incision. The right maxillary molar, which had periodontal inflammation, was also extracted. One day postoperatively, severe hypopyon developed, although the periocular swelling was reduced. These signs persisted despite topical and systemic antibiotic and anti-inflammatory therapy; therefore, the right eye was enucleated 1 week later. Intraoperatively, a fistula was found connecting the orbital medial wall, right maxillary molar root, and sclera. The fistula entered the dorsomedial sclera approximately 7 mm behind the limbus. Enterobacteria were cultured from the area. Foreign bodies can enter the anterior chamber not only through the cornea, but also through the mouth. Therefore, when the entry point cannot be found in the cornea, a careful dental examination is required, and the foreign body must be removed through the sclera rather than the cornea.

Objective : The aim of this study was to investigate risk factor, precaution and treatment of aspirated foreign body during dental procedure. Material and Methods : Twenty cases of accidental aspiration of the foreign body, which removed by bronchoscopy at the Asan Medical Center between 2008 and 2012, were analyzed retrospectively. Results : Ten cases of accidental aspiration were occurred during dental procedure. Symtoms include cough(65%), dyspnea(50%), sputum(25%) and wheezing(25%). The most common location of foreign body was right bronchial tree(50%), left bronchial tree(45%) and carina(5%). Patients risk factors were chronic obstructive pulmonary disease, lung cancer, pulmonary tuberculosis, esophageal cancer and vegetative state. Conclusion : Accidental aspiration or swallowing of dental instrument or material is not uncommon accidents in dental practice. Most foreign bodies enter into gastrointestinal tract spontaneously. But aspiration into broncho-trachea can be more serious events and must be treated as an emergency situation. Prompt emergency treatment and removal of the foreign body is necessary to avoid complication. Dentists must have knowledge about the precaution and be ready to deal with foreign body aspiration during dental procedures.

A foreign body in the airway can be a potentially life-threatening event. The diagnosis and treatment of foreign bodies in the airway are a challenge for otolaryngologists. Despite the improvements in medical care and public awareness, approximately 3,000 deaths occur each year from foreign body aspiration. A high degree of vigilance is required to ensure prompt treatment and avoid the complications of foreign body aspiration. The author encountered a case of a 77-year-old female patient who had aspirated an unknown foreign body that was fixed in her main bronchus. An initial attempt was made to remove it with a flexible bronchoscope but failed due to the patient's hypoxemic state during the procedure. Under general anesthesia, a rigid bronchoscopic examination was performed, but it was difficult to approach the object due to the bronchus curvature. Instead, a cryotherapy instrument of bronchoscopy was applied. The foreign body was frozen and removed to the carina, where a laryngoscope and laryngeal forceps were used to remove it.

Baculovirus occlusion bodies have been recently engineered to incorporate foreign protein such as the Bacillus thuringiensis (Bt) CrylAc protein for improvement of insecticidal activity. In this study, polyhedrin, cylAc, egfp and crylCa genes were fused to produce occlusion bodies that contain novel recombinant crystal protein by homologous recombination between cylAc and crylCa genes in insect cells.

Fractured tracheostomy tube presenting as foreign body in the tracheobronchial tree is very rare. Authors experienced a case of broken tracheostomy tube presenting as a foreign body in the trachea, which was removed with the help of flexible bronchoscope. A few causes could be suggested for the tube break: aging and deterioration of the tube with repeated use, a flaw of the tube in the manufacturing process, and a wrong sterilization.method causing weakness of the tube. We report this case with brief literature review.

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.

Foreign bodies of the parapharyngeal space can cause severe complications such as descending suppurative mediastinitis, jugular thrombophlebitis, cavernous sinus thrombosis and carotid erosion. Therefore, early diagnosis and surgical intervention are needed to reduce morbidity and mortality. We present a case of a toothbrush as foreign body in the parapharyngeal space in 28-year-old male patient. The tooth brush was broken and the remnant of that was left in the patient's mouth. Under general anesthesia, intraoral approach was undertaken and successfully the toothbrush was removed, and then incision and drainage was done by transcervical approach. We report this case with review of literature.

식도 이물은 이비인후과 영역에서 흔히 볼 수 있는데 이중 주화가 대부분을 차지한다. 대부분의 경우는 내시경적 방법으로 용이하게 제거할 수 있지만 특수한 경우에는 수술을 요한다. 최근 본교실에서 경험한 1례는 약 1년 여의 병력을 가진 4세의 여아로서 기관분지 부의 상부, 기관과 식도사이에 개재한 동전(10원)을 전신마취 하에서 관혈적으로 제거하는데 성공하였다. 본증례는 빈도가 극히 희귀하고 흥미있게 생각되어 문헌고찰과 함께 보고하는 바이다.

A 33-year-old man presented to the plastic surgery department for foreign body removal 1 month after the insertion of a continuous glucose monitoring (CGM) sensor (Dexcom G5) in the left upper arm. The patient had used the CGM system for 5 years, and the insertion was done in the usual manner. The entire sensor wire was visible on simple radiography and ultrasonography. In the operating room, and the sensor wire was identified in the intermuscular septum and removed. No foreign body reaction or inflammatory signs were found around the CGM, and the extracted wire measured 2.5 cm. Thus, it was assumed that the whole sensor wire was detached from the transmitter, not fractured. No remnant foreign body was observed on follow-up simple radiography.
